Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
10/4/2015 11:59 PM 0.33 M M M M Hit & miss tropical-like showers tracked E/NE across our location this day as an U/L low spins across northeast FL. Cooler & drier air on the backside of this feature & C-3 Hurricane Joaquin has brought our temps down several degrees. This variable, in addition to some low-level convergence has triggered bouts of scattered rain.
10/27/2015 11:59 PM 0.37 M M M M A surface disturbance, remnants of what was once Hurricane Patricia, continues to track across the northern Gulf states. This feature has an associated cold boundary stretching from NE/SW separating a very rich tropical air mass east of the boundary w/ a much drier air mass west. Ahead of this advancing front is a large warm sector w/ precipitable water values trending to nearly 2.00 inches...a 90th percentile above historical norms for late October. Showers & a few embedded isolated low-topped convective cells have been slowly advancing eastward toward the FL west coast. The front is expected to cross our location sometime tomorrow afternoon. Until then, we can expect scattered rain w/ pds of heavier rainfall during the overnight hrs & tomorrow.
10/28/2015 11:59 PM 0.62 M M M M Light to moderate steady rain fell during the early morning hrs in advance of a cold boundary advancing from the NW. Our region continues to remain w/in the warm sector thou a much drier air mass will filter in from north to south. Warm temps, however, are expected to remain.
11/7/2015 11:59 PM 0.22 M M M M Scattered sea breeze related showers have been drifting from east/west as 2 large dominating highs remain anchored across the eastern third of the US. Unseasonably warm temps w/ many areas breaking all time highs continue into its 7th day over the southeastern US & the FL peninsula w/ temps in the low 90s & dew pt values ranging from the low/mid 70s. No changes are expected for at least the next 48 hrs as an U/L disturbance moves across the FL/GA border bringing changes on Monday.
11/19/2015 11:59 PM 0.77 M M M M N/A

11/24/2015 11:59 PM 0.04 M M M M N/A
12/30/2015 11:59 PM 0.06 M M M M Passing tropical-like showers during the early morning hrs w/ on & off sprinkles. Record heat w/ temps trending in the mid-80s for across most regions.
1/2/2016 11:59 PM 0.16 M M M M A wide & mostly light/moderate rain column preceding a cold front had finally arrived after wks of record heat. On & off light showers should continue into the morning hrs although the precip will gradually clear from north to south. Temps that were trending at or above record levels (mid 80s)for nearly the entire month of December are expected to trend anywhere from 15-20 degrees cooler...& back to where they should be for early Jan.
1/8/2016 11:59 PM 0.31 M M M M One in a series of passing boundaries produced pre-frontal scattered showers w/ patchy & isolated heavier rain. Over the next few wks our region is anticipating a series of conga fronts that will provide warm & humid conditions w/in a large warm sector w/ much colder & blustery NW winds behind the front. A few of these will be of Arctic origin that may provide an excellent breeding ground for isolated severe weather.
1/14/2016 7:00 AM 0.60 M M M M SPC Marginal Risk threat for severe weather for all of west/central FL. Intense surface low (1005mb/29.68") formed over the NW Gulf & tracked quickly across the northern Gulf. Weakening squall line crossed our region & was quickly gone. Tornado confirmed in Cape Coral.
1/22/2016 11:59 PM 0.81 M M M M Another round of quick-moving thunderstorms...w/ at least 3 EF-1 tornadoes touching down in Sarasota & Manatee Ctys w/ 1 twister claiming 2 lives. All of west/central & southwest FL were shaded w/ a Slight Risk threat for organized storms this afternoon & evening. Most of the concentrated energy was located south of our location.
1/27/2016 11:59 PM 1.60 M M M M A Marginal Risk threat for organized thunderstorms was issued by the SPC for all of west/central, southwestern, east/central & southeastern FL this afternoon. Mostly cloudy skies & a rain-cooled environment acted to stabilize our atmosphere w/ light to moderate rain over our region. At least 3 confirmed EF-1 tornadoes touched down in southeastern FL w/ 1 twister causing damage in Coconut Creek...about 10 miles north of Pompano Bch. This has been the 3rd straight week the SPC had shaded our region w/ the threat of organized thunderstorms w/ a Marginal or Slight Risk. It's still January w/ more to come.
1/28/2016 11:59 PM 1.38 M M M M Bands of moderate/heavy rain associated w/ an approaching cold boundary crossed our region this day. The SPC shaded most of west/central & southwest FL under a Moderate Risk threat as a series of impulses trained along a cold front that stretched from NE/SW. There were no reports of severe weather across our immediate area. However, areas across southern/southeastern FL reported at least 3 EF-1 tornadoes doing damage...specifically Coconut Creek. No injuries and/or casualties. Much cooler air mass to filter down the spine of FL
2/4/2016 11:59 PM 0.87 M M M M Pre-frontal rain finally arrived as the cold front draped across our Big Bend region that stalled for a time yesterday resumed its E/SE propagation. Moderate to heavy rain continued for most of the afternoon into the evening hrs. Record highs of 84 yesterday & 84 Tuesday (2nd) will be replaced w/ temps trending 25-30 degrees colder this weekend.
2/16/2016 11:59 PM 0.15 M M M M Quick-moving pre-frontal rain w/occasional lightning flashes passed thru during the early morning hrs. A tornado watch was issued btwn 2 & 8am for most of west/central FL although no reports of any damage or specific activity were rec'd. However, at least 2 tornadoes were reported south of Miami during the morning rush hr w/ damage to various structures (EF-1). Much cooler & drier for the remainder of the wk.
2/22/2016 11:59 PM 0.15 M M M M The initial surge of tropical moisture well ahead of an intensifying surface low forming over eastern TX triggered brief showers across our region tonight. A deeper moisture surge will be well underway by the morning as this surface low tracks E/NE thru the Arklatex tomorrow. This system is expected to trigger a widespread & significant outbreak of severe weather across the south/central Gulf state beginning Tuesday afternoon (2/23) into our region Wednesday morning (2/24). The SPC has elevated the threat to Enhanced Risk for most of the region w/ a Slight Risk for most of west/central FL.
3/13/2016 11:59 PM 0.11 M M M M Scattered light/moderate rain crossing our location during the early evening as a stationary front stalls to our NW. Additional light/moderate rain is expected tomorrow
3/19/2016 11:59 PM 0.33 M M M M Bands of pre-frontal showers/storms tracked across our location thru out our morning hrs. There were embedded strong clusters that showed vortex signatures as they approached from the NW. This prompted the SPC to post a severe thunderstorm watch for our southern/southwest regions. Temps behind the boundary are trending some 10-15 degrees below mid-March norms w/ blustery NW winds. Much cooler weather will settle across west/central FL w/ a rapid warming trend beginning by mid-wk
3/24/2016 11:59 PM 1.76 M M M M Cold pool driven QLSC advanced from NW/SE producing torrential rainfall, damaging wind swaths 65+mph & small hail crossed our location. System was part of a much larger convective system that produced damaging winds & large hail across our Panhandle earlier this afternoon/evening. The entire region of west/central & areas of east/central FL have been shaded for a Marginal Risk threat for tomorrow as well. Stalled boundary along the base of a large trough will remain draped across the FL/GA border region for at least the next 24-48 hrs. Model guidance shows several weak energy vorticies will spin across the boundary while surface CAPE, PWAT & dew pt values will offer decent instability & marginally favorable environment for strong/severe thunderstorms.
3/26/2016 11:59 PM 0.65 M M M M A picturesque, spectacular shelf-cloud preceded a line of marginal/strong thunderstorms crossed our location this afternoon. The low-hanging, multi-layered QLSC produced downdraft winds of 50+ mph & torrential rain. Temps dropped 15 degrees in about 20 minutes w/ some areas sustained damage.
4/2/2016 11:59 PM 1.24 M M M M Another QLSC crossed our location early this morning. The NWS issued marine warnings from Englewood to Tarpon Spgs w/ wind gusts exceeding 40 kts. In addition, there was a tornado warning issued for our area (radar observed) w/ some brief mid-level rotation indicated. That expired quickly. Much cooler & drier air to filter in for the early work wk
4/7/2016 11:59 PM 0.17 M M M M Strong QLSC moved onshore producing a waterspout which became an EF-0 tornado causing damage to a small region near Pt. Richey. More fronts are expected to cross our region over the next 48 hrs bringing unusually cold air into west/central FL
4/20/2016 11:59 PM 0.12 M M M M Pre-frontal rain quickly crossed our location today. Warm & moist sector to be replaced w/ some slightly drier air offering an excellent rest of the wk into our weekend.
5/4/2016 11:59 PM 2.96 M M M M Two rain events this day as a late season powerful cold front approached: the first convective system crossed around dawn as a QLSC pushed thru our location. These storms caused scattered pwr outages, downed trees & wires as the entire line tracked E/SE. The 2nd came as the actual boundary moved thru our location w/ prolonged pds of moderate to heavy rain. Clearing skies quickly appeared w/ much drier air building down from the NW. Beautiful weather expected for the next several days.
5/16/2016 11:10 PM 0.63 M M M M Sea breeze rainfall was triggered in 2 phases during the late afternoon/early evening. Elevated moisture from an area of disturbed weather will be moving into our region during the early morning hrs. Surface instability & cold temps aloft will provide an extra punch for storms tomorrow. Some may become severe. Looks like our summer rainy pattern has started early.
5/17/2016 11:59 PM 0.54 M M M M Large MCS tracking across the northern Gulf arrived around the dinner hr w/ numerous marine warnings generated. Regions east of our location received several inches of rain w/ Vero Bch recording 11+" & widespread flooding. This meso complex will be 1 of several impulses moving across our region over the next 48 hrs. A Marginal Risk threat was shaded late in the afternoon.
5/28/2016 11:59 PM 0.26 M M M M Sea breeze boundary combined w/ just enough moisture available provided a sun shower. PWAT values were just over 1.00"...nearly 2 std deviations below late May norms...but enough for the unexpected rain.
5/29/2016 11:59 PM 0.77 M M M M Gulf breeze had much more moisture to work w/ today. In addition, the breeze moved inland fairly early. Temps were already at 90 as towers began building from the west. Temps @ 500mb were -9C/-10C thus some storms had an extra punch. Fairly robust downdrafts w/ a few as well. Looks like the rainy season has started.
5/31/2016 11:59 PM 0.36 M M M M Convective line formed & tracked eastward around the dinner hr. Storms were slow movers thou most activity passed our location early. Some inland zones received large amts of rain while those areas along the western beaches received nothing. More is expected tomorrow as we move into our summer pattern.
6/5/2016 11:59 PM 0.20 M M M M A very brief & quick-passing shower crossed our area. This was one of many scattered shower/outer rain bands from newly upgraded TS Colin currently located about 480 miles SW of Tampa. TS warnings have been posted for the entire FL west coast from Sarasota northward to our Panhandle. A flood watch has also been issued for all rivers & streams. Coastal flood watch also in effect for the TS warned region. Colin's numbers: 1003mb/29.62"; PWATs 2.25+"; wind field 45; radius wind envelope 325 miles; track 360 degrees @ 9
6/6/2016 11:59 PM 2.42 M M M M Torrential rain from TS Colin began being felt late last night w/ a few quick-passing showers occurring overnight. As his ctr moved closer toward our Big Bend, his winds & rain bands became more frequent. Two outer bands crossed our location during the morning commute w/ the heavier squalls & sustained rain taking place during the mid-afternoon/early evening. Wind gusts reported @ TIA reached 41 while some other communities exceeded 50. Flooding took place at the Bayshore area via south Tampa. Flood watches are also posted for Tuesday morning thru 5pm. Will be on vacation beginning tomorrow thru 6/14.
6/7/2016 10:13 AM 2.91 M M M M Additional training rains continued during the early morning hrs as Colin vacates into the Atlantic. A thin corridor of moderate to heavy rain remains in progress across our region & this corridor is expected to drift & meander north-to-south & back north again thru out the day. Leaving for vacation in about 15 minutes.
6/15/2016 7:00 AM 0.00 0.0 M M M Returned from vacation
6/18/2016 11:59 PM 0.24 M M M M Sea breeze triggered storms tracked across our locations this afternoon. Storms formed late.
6/23/2016 11:59 PM 0.17 M M M M Late activity from outflow boundaries made their way thru my location which took place after midnight. Another round of mid-level sea breeze activity came thru around the dinner hr. Strong subsidence capped our atmosphere limiting any significant activity today.
6/26/2016 11:59 PM 0.55 M M M M Active convection propagated from NE/SW triggered from a series of U/L vorticity max vacating the FL/GA border into the Atlantic. This convective line encountered a robust Gulf breeze w/ 500mb temps on the cool side (-8 C) triggering severe thunderstorms across our location. Some damaging winds were reported w/ these storms in addition to qtr size hail. None of these were present at my location. More storms are expected tomorrow although not as severe.
6/28/2016 11:59 PM 0.77 M M M M Sea breeze set up & moved eastward firing off slow moving cells. PWATs nearing 2" for precip loading w/ very little in terms of steering flow yielding torrential rainfall over our location. Wind fields will be mostly W/SW for the next several days providing a typical convective set up.
7/1/2016 11:59 PM 0.07 M M M M Sea breeze outflow boundary skimming our location as our region remains locked w/in a dominant W/SW flow tapping pure Caribbean moisture. Storms initiate early & advect E/NE where heaviest activity is found across our east/central zones. More of the same for the next several days.
7/7/2016 11:59 PM 0.57 M M M M Nasty convective cells sprung in spite of a hostile environment along an advancing sea breeze. Cells formed along a narrow corridor across our location w/ vivid CG strikes every 10-12 seconds. Storms are slow movers due to our region close to a ridging high ctr. Cells had to fight suppressive subsidence w/ a marginally strong cap @ 875mb/0.625 miles.
7/8/2016 11:59 PM 0.15 M M M M Storms fired along a convergence zone although the most active convection remained to our NW. Stacked ridging remains nearly on top of our location w/ most zones suppressed w/ strong subsidence. The land breeze that is generated during the early morning hrs gives way to the sun which cuts off the land breeze & the convective process begins along the west coast. Only spotty storms in the forecast once again for tomorrow.
7/9/2016 11:59 PM 1.12 M M M M Sea breeze convection fired along the Gulf convergence in spite of hostile U/L subsidence. West/central FL remains wedged btwn 2 ridging highs w/ the first (1021mb/30.11")sitting nearly on top of our location w/ the 2nd (1024mb/30.24") being the sub-tropical ridge located about 1000 miles east of Ft. Lauderdale. Better chances for afternoon storms will take place this wk.
7/10/2016 11:59 PM 1.31 M M M M Highly electrified CGs embedded w/ severe thunderstorms crossed our location during the late afternoon hr. Brief pwr outage occurred. Storms fired along an advancing Atlantic breeze as the Gulf breeze collapsed. More storms are expected tomorrow.
7/11/2016 11:59 PM 0.31 M M M M Another round of sea breeze convection crossed our location although not as severe as yesterday.
7/12/2016 11:59 PM 0.07 M M M M
7/15/2016 11:59 PM 0.33 M M M M A line of severe thunderstorms passed just south of our location tonight. This line formed late along the advancing Atlantic breeze & numerous outflow boundaries and tracked SE/NW. Pwr outages reported in areas of northern Hillsborough Cty although Pasco remained fairly unscathed. Awesome shelf cloud was observed in advance of this line. Half inch hail & 65mph downdrafts accompanied this storm.
7/18/2016 11:59 PM 0.33 M M M M The sub-tropical ridge (1024mb/30.24") remains anchored about 1000 miles east of the FL/GA border. This is expected to move closer to our peninsula over the next few days offering a dominant easterly flow pinning the Gulf breeze close to the beaches. This has yielded storms west of the I-4/I-75 corridors over the past few days w/ a few crossing our area. In the meantime, record heat is also in place (95 today @ TIA). Temps @ 500mb remain quite cold for mid-July (-8 C). This has yielded a few strong/severe storms locally. More of the same expected for tomorrow.
7/19/2016 11:59 PM 0.27 M M M M Sea breeze storms kicked off a bit faster than anticipated as the sub-tropical ridge's westernmost axis gradient firmed up during the early morning. This escorted the Atlantic breeze across our peninsula much quicker which fired off convection sooner. Some storms attained severe limits w/ over 200 CG strikes w/in a 30 minute time. There were at least 2 house fires caused by the strikes in addition to separate CGs striking at Clearwater Bch & Sand Key causing 2 injuries; 1 critically. Tomorrow's set up looks similar to today's w/ little change for our overall synoptic environment.
7/21/2016 11:59 PM 0.06 M M M M
7/24/2016 11:59 PM 1.62 M M M M Sea breeze circulations, relatively cold 500mb temps & a weak U/L disturbance combined to produce scattered strong/severe thunderstorms across our region this afternoon. Storms also produced pds of torrential rain as they passed from SE-NW. Scattered swaths of damaging winds were reported in Hudson...not very far from here. Some drier air will be filling the vacating TUTT tomorrow. That, w/ slightly warmer temps aloft will reduce the overall convective coverage thus much less activity is expected.
7/27/2016 11:59 PM 0.16 M M M M The convective field was late to get going due to sinking subsidence aloft & the over abundance of dry air. Capping layer was also marginal to strong @ 810mb/2640 ft. However, a handful of cells broke thru the cap quickly rising to 8+ miles @ their EL. Storms approached from the SW late offering quite the light show.
7/30/2016 11:59 PM 0.16 M M M M Only a shower from a passing & dying thunderstorm during the early afternoon. Pattern change has convective activity taking place during the early part of the day while our east/central zones get the heavy stuff late. A TUTT disturbance is expected to cross south FL tomorrow w/ a much drier air mass aloft. Thus, the convective process will occur late in the day west of I-4/I-75
7/31/2016 11:59 PM 0.91 M M M M A TUTT disturbance is expected to track over our peninsula tomorrow. Ahead of this feature is a larger column of colder & drier air aloft. This feature, in addition to two ridging highs on each side of FL , has increased subsidence & suppression...inhibiting and/or delaying the convective process. Storms arrived much later than normal as the Atlantic breeze encountered the Gulf winds. Storms initiated along our beaches w/ outflow boundaries generating secondary storms. Some of these secondary storms crossed our location generating quite the light show for all.
8/2/2016 11:39 PM 2.13 M M M M The atmosphere was set for strong/severe thunderstorms as surface diurnal heating trended from 95-100 degrees; PWATs nearing 2" & 500mb temps ranging from -7/-8 C. The LFC was a marginal 820mb/2000 ft w/ CAPE values for Lapse Rates @ 3000+ j/kG. Torrential downpours & vigorous CG strikes were common as these cells tracked W/NW tonight
8/6/2016 11:59 PM 0.25 M M M M FLOOD WATCH ISSUED-An U/L disturbance continues to spin across our Big Bend drawing a pure tropical air mass into/over FL. This system is also being monitored for potential development later next wk. In spite of only 1/4" rain measurement, the blanket of rainfall will begin to spread southward into Pasco Cty later tonight thru Sunday.
8/7/2016 11:52 PM 0.73 M M M M Tone alarm for strong thunderstorms triggered early this morning as we moved to 48 hrs of rain fall. U/L low continues to spin over NW FL/NE Gulf w/ a pure tropical air mass (PWATs ~2+")continues to sprawl across the FL peninsula. Flood Watch posted for Pasco Cty northward to Levy. Rain retreated during our afternoon hr w/ only very light sprinkles. A third round of heavy rain is expected overnight & most of the day Monday
8/8/2016 11:59 PM 0.97 M M M M Another day of torrential rainfall w/ below avg temps. The surface & U/L low (1010mb/29.83") spinning across our NE Gulf continues to dominate our weather w/ spokes & energy ripples over/thru our location. Depending where you are, rounds of heavy rainfall has trained over the same areas causing minor flooding & standing water in isolated spots. The pattern begins during the early morning hrs w/ a 2nd round arriving during the mid-afternoon. This non-tropical low is expected to slowly drift NW & lose its grip on our weather while western Atlantic ridging finally builds across. This is expected to begin late Tuesday/early Wednesday.
8/10/2016 11:59 PM 0.23 M M M M Sea breeze storms approached w/ a vengeance although our location was spared w/ most of the torrential rainfall. Some locations just west of here rec'd 2+" of rain. More of the same is expected tomorrow.
8/17/2016 11:59 PM 0.94 M M M M Late sea breeze storms crossed our location tonight. Dominant E/SE Atlantic breeze continues to cross the FL peninsula & encounter the Gulf winds. Most activity has been confined west of the I-75 & has arrived late. Temps at 500mb remain btwn -7/-8 C & has elevated our instability values. PWATs have also remained near 2". Thus, in spite of the brevity of the storms, they have put down good rainfall. More is expected tomorrow.
8/18/2016 11:59 PM 0.27 M M M M Passing sea breeze storm brushed our location as cells moved from SE/NW. Pattern change is expected to bring our winds from the W/SW this weekend suggesting storms to fire during the early morning hrs & track eastward toward our central zones.
8/19/2016 11:59 PM 1.27 M M M M Slow moving sea breeze storms get a late start as a change to our pattern has initiated. Atlantic winds arrived late to the Gulf while the Gulf breeze advected further inland. Storms fired along the convergence & were slowly pushed back west. Today was considered our transition day as activity will begin early along the coast tomorrow & push inland for the afternoon & into the Atlantic during the evening.
8/31/2016 11:59 PM 3.27 M M M M Outer rain band from Invest 99-L soon to become TD #9 crossed our region for most of the day w/ squalls containing very heavy rain. 99-L/TD 9 has sustained winds of 35 mph w/ higher guts & is currently located about 435 miles W/SW of Tampa moving W/NW @ 5. 99/TD-9 is expected to take a turn toward the N/NW & then N/NE by tonight morphing into a tropical storms by that time. TS watches are likely along the FL west coast sometime tomorrow morning w/ all of the associated problems.
9/1/2016 11:59 PM 2.70 M M M M TD 9 morphed into TS Hermine this afternoon w/ sustained winds of 45mph. Hermine is located about 235 miles W/SW of Tampa moving N/NE @ 7. Central pressure 1005mb/29.68" w/ most of the heaviest weather confined to his eastern semi-circle. After a rainy night our morning broke quiet. This was the quiet before Hermine's secondary precip wall advanced from the S/SW. Hermine became a C-1 storm just before the dinner hr w/ sustained winds of 75. Hurricane warnings/TS warnings posted for all of FL west coast from Englewood northward to Apalachiacola. A tornado watch #460 was issued w/ #461 replacing it from 11pm thru 8am tomorrow morning. More squalls to cross our location during the night as Hermine made landfall near St. Marks.
9/2/2016 11:27 PM 4.20 M M M M Relentless squalls from Hurricane Hermine crossed our locations during the early morning hrs triggering tremendous amts of rainfall tropical storm-force winds. One squall crossed our location @ 4:45am that was very frightening. Amazingly we did not lose pwr although the house shook w/ the wind's pulsation. Hermine made landfall last night near St. Marks, FL as a C-1 storm. Many areas along the FL western coast from Tampa northward were flooded, down trees & pwr lines, reported structure damage & there were a few reports of isolated tornadoes. Scattered pds of torrential rainfall associated w/ Hermine continued to train across our area. One for the history books.
9/3/2016 11:59 PM 0.33 M M M M Hurricane Hermine is now moving thru the Carolinas. In spite of his being long gone, very deep moisture remains behind w/ a very deep SW/NE flow. Numerous tropical rainfall in trailing pools have crossed our location very quickly today. Our atmosphere will attempt to dry out as drier air tries move southward. Flooding remains a large issue for many communities north & west of here.
9/5/2016 11:59 PM 0.37 M M M M Afternoon sea breeze generated showers crossed our location w/ much heavier storms SW of here. Rich PWATs remain in place in lieu of Hermine's departure. Some drier air is expected to filter in tomorrow & offer good drying over the next few days. We need it.
9/13/2016 11:59 PM 0.55 M M M M TS Julia formed a few hrs ago off the coast of Jacksonville. Winds are sustained at 40 w/ most, if not all, heavy weather confined to her eastern semi-circle. On her western side, not much is taking place w/ winds mostly light & variable & only scattered showers/storms. Winds have shifted from the W/SW allowing quick-moving tropical-like showers to cross our location. More of the same is expected tomorrow.
9/14/2016 11:59 PM 0.07 M M M M Scattered tropical-like showers crossed our location today although depending where you were specifically located highly depended on your total precip. Julia's winds continued to dominate our flow w/ a W/SW field keeping most activity confined to our interior. However, significant rain fell only 5 miles east of our location. Less steering flow will offer a better Gulf breeze tomorrow providing similar hit-&-miss activity w/ most taking place across our interior zones.
9/21/2016 11:59 PM 0.11 M M M M Late sea breeze convection developed as the Gulf winds encountered the Atlantic's flow w/ most activity tracking eastward. The overall convective field was hostile w/ PWATs above 600mb btwn 1.30-1.50". In addition, sinking subsidence aloft provided CINH of -132 keeping most cells at bay for vertical updrafts. Similar set up is likely for tomorrow as the Autumn Equinox begins.
9/26/2016 11:59 PM 0.13 M M M M Late & brief sea breeze crossed our area as summer continues to hold on.
