About as wintery as it can get this early in the season (yesterday's mean temperature of 10F was more than 30F below the long-term average). Light flurries in AM yesterday, riming overnight.

Breezy rest of the day, but apparently not enough to dislodge snow off trees about 1000' below us as witnessed this morning. Fairly calm and mostly clear this morning. |

Just saw a report that our biggest neighborhood lake (1/8 mile across) is 4" frozen, enough to carry people safely. This is one of the later reliable freeze-overs I can remember (lakes actually froze over in early October with that first cold snap, but then melted out again; ditto in early November).

Tmax: 15 (12 before midnight); Tmin: 0 (9 since midnight). Another windy day, messing up driveways... I just crunched thru the numbers from December 1-10, and my average temperature was +3F, or about 20F below my 1990-2009 averages! I can think of only one cold snap that was colder since 1990, and that was back in late December 1990. Of course, there were a couple of cold snaps in the 80s that would have been colder, especially in February '89 and December '83. |

Measured 0.10/1.2" on snowboard late today upon our return from Redstone, I prorated the snow based on one day settling on snowboard (assuming that there was no sublimation in gage, but that the initial 0.2" two days ago and about 1.3" yesterday reduced to 1.2". One more note: we drove up to McClure's pass in morning (8am), and it was -4F (car thermometer) at the base of the pass (near the turnoff to Marble), but +10F at pass level, a typical midwinter inversion. |

Oh well, this one got away (radar seemed to indicate earlier and heavier snow as close as Nederland). Clear this morning at our house, but a cloud deck below about 7.5-8K to keep the lower elevations much warmer overnight. |

While we started with 10:1 ratios early yesterday, we finished off extremely fluffy in the evening (last 1.8" after 8pm contained 0.03" of water, snow ending by about midnight). Fairly gusty north to (later) east winds during the storm, but dead calm and mostly clear this morning. Snow depth last evening: 30" - settling fast with such fluffy snow... 2d storm totals: 20.4/1.06" (4th(9th) biggest March snow-(H2O-)storm since 1991). |

Tmax: 35; Tmin; 13. Good 2nd storm within five days! We reached over 2"/h from about 4:30-7:30pm, and at least 1"/h from about 4pm until past midnight MDT. According to a neighbor, we had 'blizzard conditions' right after noon, followed by a lull in the early afternoon, while heaviest snow in the early evening had some gusty winds out of the northerly sector. That wind may have prevented our power from going out (it sure flickered a few times), since it reduced the load on the power lines. It is still snowing lightly this morning at 7am, but should be over soon. Total so far for storm: 21.5/1.60", should end up just above 22". Combined with the storm five days ago, we have received 41.9/2.66", surpassing the snowfall totals of a similar double-hit in early March 1992 (by about 1"), but lagging behind by more than 1" for H2O. Because this second storm had more water than the first, the snow depth increase ended up being more impressive as well, from 19" before onset to 36" earlier this morning, before it started settling. |

Interesting tidbit: on our drive along 285, the temperature dropped from the low 40s near Bailey to the low 20s near Fairplay and 10F by the time we reached the southern end of South Park (just before noon MDT). It was also pretty unique to have full snowcover all the way to Salida, can't remember the last time I have seen that. I guess the snowstorm earlier this week refreshed the snowcover of the whole region. |

Snow finally began well after midnight, must have reached 1"/h or more before sunrise. Still snowing pretty good, with big fluffy flakes reducing visibility to about 1/4 mile.

A second round of storms rumbled thru later that evening, changing to wet sloppy snow (about 0.1" H2O with 0.2" slush) after midnight. That slush was still there this morning, along the edges of the leftover snowfields (~30% coverage), and on elevated surfaces. More to come in the next 48h, looks like this April will redeem itself after all... |

Tmax: 53; Tmin: 28 (it dropped just below freezing by midnight MST - now the continuous run of freezing lows has tied the record of 180!); spill-over precipitation switched to snow after being measurable (8pm), clear and finally near-calm this morning. Yesterday's winds reached 61mph on a neighbor's wind gage before knocking out power at 3:20am (took almost 6h to restore it). Apparently some full trees toppled onto powerlines in our neighborhood to cause this outage. |

Need another 22" and change to break my all-time record (1997-98) - thought this was out of reach, not so sure anymore (although it will be harder to get better than last night's snow-H2O ratios from here on out, looking at next week's storm temperatures). |

The 3d total of 2.49" is also my 2nd highest June total (early June 91 had 3.84" in 3d). Some snow pellets mixed in for the evening thunder shower after 6pm to give me a 2nd trace for frozen precipitation. Drove up Brainard Lake road to the gate where I talked with people who told me that they had received 5" of snow overnight at the lake. At this time (3pm), it was sleeting at the gate (10K), and there was snow on the ground just one mile above Peak-to-Peak highway (I would say above 9.5K). More showers today, then a slow warm-up/drying out for the rest of the week, although I am not convinced that the next trough will pass by without triggering more thundershowers around Wednesday/Thursday. |

Looks like our little wet spell (triggered by Alex?) is winding down, but not before dropping almost 2" of rain on us since July 1st. A remarkable wet spell, second only to the same period in 2006 which dropped over 2.6" on us. The median precipitation for the same period (July 1st thru 8th) is only 0.23", reflecting that this is typically one of our driest times of year, so this is is oven more impressive compared to what we normally get. Should keep the fire danger down a little longer. |

We got side-swiped twice yesterday - once around 3:30pm when somewhere close to 8" of hail were reported near Nederland (and radar estimates of 2-3" southwest of NED), and once a little later when a big storm raked southern Larimer County east of Longs Peak (based on radar). Oh well, 0.19" is the highest since July 8th, so I am grateful for every fraction of an inch these days. In fact, our total of 0.41" for the 20 days from July 9th through July 28th is the lowest in my 21-year record! |

Drove to ELDORA (about 3W Nederland) yesterday evening to 'sample' the after-effects of the big hail storm they had the day before. There was still plenty of pea- to marble-sized hail that had been plowed to foot-high berms on the side of the road mostly just east of Hessie, with sufficient ground cover everywhere to still be on the order of 2-4" on average. Lots of aspen foliage down as well, and a layer of haze (around 7pm MDT) from the local evaporation. What a scene! |

Tmax: 60; Tmin: 31. Very windy yesterday morning, estimating top gusts around 60mph, right around the time that the Four Mile Canyon fire took off (10am-1pm or so). Wind switched from strong northwesterly to light upslope in the evening so that we got to see some floating ash flakes from the fire (which burned about 5-6 miles southeast of us). Clearing late, and drainage flow to give us much better air quality at home than down here in Boulder where we had to go today. Second freeze of the season, probably helped in containing the fire this morning. |

Today is the best chance for moisture all week, with what looks like remnants of the moisture that 'Karl' brought to Baha from the Atlantic being steered into Western Colorado (I am just hoping for some of that to spill-over). There is actually a flash-flood watch in SW Colorado where 1-2" are expected/possible. Due to tropical origin of this moisture, snowlines should stay mostly above treeline. |
