Snow began around 3:30 and lasted through the night. Heaviest snow occurred from just before 4pm through just after 5pm. 2.5" fell between 3:30-5:30pm. A total of 3.9" was measured shortly after midnight, with some compression occurring by morning. Light flurries continue at time of observation.

New snowfall measurement made at 1pm, but is consistent with new snow depth this morning as well. Total SWE is down likely due to fluffier snow on top (20:1) and some heavier snow leaking water into layer of ice underneath snow (frozen sleet/rain mix; not included in snow depth or SWE measurements).

Between 3-5pm and after 8pm were some of the heaviest rates, approaching an inch/hr. 4.3" measured as of 11pm last night. Stayed north of heaviest banding per radar. With some wind, gauge appears to have under-caught snow vs. core SWE. 6.1" represents depth, likely with some compaction despite crystaline/"fluffy" nature of snow.

Fine flakes fell through most of the day, with only a few tenths down as of the evening. Measurement after 10pm recorded about 1.8" of new snow. New snow depth was 5.3", combining measurements of 1.8" and 3.6" for a new snow total of 5.4". Snow is currently heavy as of time of report (30 mins after listed ob time).

Snow fell throughout much of the day yesterday, with a couple of heavier bursts in the early afternoon. 1.7" of new snow fell, although it only measured 1.5" by this morning. Snow depth/liquid values getting a bit more approximate as the snow depth doesn't all fit in the tube. Fluffy snow compaction is helping to make a core sample work.
1/30/2019 7:00 AM T T T M M Did not go outside for measurement - temp at time of ob was -28F with a notable breeze.
2/1/2019 7:00 AM 0.03 1.1 0.03 15.8 2.08 Light snow began yesterday evening and accumulated quickly through at least 11pm. Snow is very high ratio due to sub-zero temperatures while snow was falling. Light snow continues this morning. Snow depth seems accurate, but the snow water equivalent values seems artificially high compared to previous values. It is hard to speak to how accurate that is given the snow depth is in excess of the depth of the outer gauge used for the core.

2/6/2019 7:00 AM 0.21 0.3 0.21 M M Precip began briefly as a light mix before heavy sleet-dominated mixed precip moved in around 5:15. Most snow/sleet accumulation is from this ~30 min period. Light sleet continued after, and freezing drizzle dominated the precip later in the evening. The sleet on the ground has a noticeable (but difficult to measure) crust of freezing rain/ice accretion above it this morning.
2/7/2019 7:00 AM 0.08 T T M M Unable to distinguish sleet from rain last night, but a period of heavy mixed precip moved through. With sleet, little measureable accumulation occurred, but likely more than a T should come from the melted core. It's frozen to everything though, and is not measurable. Some light snow may have also come through overnight, as the ice seems to have a light dusting on most things this morning.
2/8/2019 7:00 AM 0.26 T M M M Precip is largely freezing rain and a little bit of sleet through around 1pm yesterday, at which point precip switched over to light snow at the back end of the storm. Freezing rain was heavy at times. A brief round (~30-60 seconds) of small hail, perhaps pea-size, also occurred around 11:35am. Flash freeze of post-storm slush in the evening. Report delayed due to rain gauge frozen in place this morning - some sun (despite only being 8F) and a few more firm hits freed it this afternoon.

Early yesterday morning, ice accretion was occurring - some on sidewalks/pavement, but much more (and for longer) on elevated surfaces and plant life - perhaps a bit more than 0.10" of accretion. Almost no ice is left due to above-freezing temps for most of the day yesterday and overnight last night. Much more in the way of rain came late yesterday with some convective elements coming through. Observed two flashes of lightning, one with an audible rumble of thunder following.
