2/4/2020 7:00 AM 0.21 0.9 0.12 M M Once again, because of the wind, the depth of snow on my snow board is totally bogus.

2/26/2020 6:00 AM T T M M M Not predicted by the forecast, yesterday, about 14:30, we received some very light, delicate snowflakes from a sky only partly cloudy. They vanished the instant they touched a surface. This lasted for perhaps 15 minutes.
2/27/2020 6:00 AM 0.00 0.0 M M M Snow coverage over 50%. Locally deep in shaded areas; shallow where unprotected. Streets and sidewalks clear and dry.
2/28/2020 6:00 AM 0.00 0.0 M T M Snow cover continues at 50% or better. Temperatures in the low 40s (°F) yesterday, with a strong wind, resulted in significant snow melt. Drifts in shaded locations still calf- or knee-deep. Snow elsewhere quite shallow. Little snow remains in street gutters. Northern exposures of surrounding hillsides still mostly covered, with some bare patches beginning to appear. Areas with full sun exposure mostly clear.
2/29/2020 6:00 AM 0.00 0.0 M T M Snow cover continues to diminish; about 50% now. Bare spots appearing on northern exposures of surrounding hillsides. Drifts in shaded locations remain deep.
3/1/2020 6:00 AM 0.00 0.0 M T M Snow cover below 50% now. Warm temperatures yesterday resulted in substantial snow melt. Bare spots increasing on northern hillsides. Drifts becoming shallower. Snow forecast for today.
3/2/2020 7:00 AM 0.21 1.2 0.11 T M Snow cover 100% again. Yesterday's snow took a long time to build up on sidewalks and streets, and with a warm, breezy, sunny day forecast, those will likely melt by the end of the day. Windy yesterday afternoon: falling snow built drifts back up that had been melting. Snowfall measurement certainly low: temperatures above freezing melted much snow as it fell, and wind was blowing surfaces clear in places.
3/3/2020 6:00 AM 0.00 0.0 M T M Snow cover near 100%, though much of the new snow melted yesterday. Streets and sidewalks dry.
3/4/2020 6:00 AM 0.00 0.0 M T M Snow cover around 50%. Most of the new snow from Sunday's storm has melted now, and we're nearly back to how it was.
3/5/2020 6:00 AM 0.00 0.0 M T M Snow cover around 33%. Warm days with wind have led to rapid snow melt. Deep drifts in shaded areas persist.
3/6/2020 6:00 AM 0.00 0.0 M T M Snow cover around 25%, but what remains is in shaded locations, and only melting slowly. It will take many warm days to finish melting sheltered snow and drifts. Otherwise, the ground is clear after several warm days this week.
3/7/2020 6:00 AM 0.00 0.0 M T M Snow cover continues to decrease. Around 20-25% now, with snow even in shaded areas beginning to melt.
3/8/2020 6:00 AM 0.00 0.0 M T M Snow cover nearly gone: it lingers only on the north-facing hillsides and shaded areas.
3/9/2020 6:00 AM 0.03 T M T M Minimal snow cover remains; perhaps 10%. New snow fell yesterday, but it was a warm day in the low 40s, and it melted as it touched any surface.

3/14/2020 7:00 AM 0.13 1.5 0.14 1.5 M Snow cover 100%. Snow did not, for the most part, accumulate on streets or sidewalks, where it melted as it fell.
3/15/2020 7:00 AM 0.00 0.0 M T M Snow cover down to a few percent. A warm day yesterday (in the low 50s) with a steady wind melted all of Friday's snowfall quickly, and made additional inroads into the snow lingering in shaded areas. Warm this morning: 38.5° at 0700.

3/17/2020 7:00 AM 0.00 0.0 M T M Very little snow cover remaining on hillsides and shaded areas. With another few days of warm weather, we could be snow free.

3/20/2020 7:00 AM 0.06 0.2 0.03 M M Light snow fell much of the day yesterday, but with no accumulation. The only accumulation began very late in the afternoon, and during the night time. Snow on the ground minimal; limited to overnight snow, plus very small amount from the winter, which has not yet melted.
3/21/2020 7:00 AM 0.01 T M T M All of Thursday night's light snow melted quickly yesterday, and snow on the ground is once again limited to those small amounts hiding in shaded areas. Light snow fell in the morning yesterday, but with no additional accumulation.

9/8/2020 7:00 AM M M M M M Power is still out in Green River. Just got internet back. Major storm during the night, with extremely high winds. Snow varies in depth from 8" in places, to bare earth, due to the high winds. A lot of snow, in any event. My snowboard held nothing, and my gauge froze and collected only what the funnel could hold: no reliable reading is available, therefore.
9/9/2020 6:00 AM 0.27 2.3 M M M Snow cover approaches 100%, deep in most places, from 6" to nearly a foot, from the drifting caused by yesterday's intense wind- and snow storm. Streets and sidewalks are largely melted. Water running in the gutters at 06:00. Significant overnight snow.
9/10/2020 6:00 AM 0.00 0.0 0.00 M M Temperatures rose into the low 40s yesterday, and there was significant snowmelt. Streets, sidewalks and parking lots are now clear. Elsewhere, snow cover is still close to 100%, and several inches deep; though in some of the sheltered areas that collected less snow, bare patches are showing through.
9/11/2020 6:00 AM T 0.0 M M M Temperatures in the 40s yesterday led to significant snow melt. Snow on the ground is now about 20%, and may finally vanish today. A light drizzle in the afternoon, but nothing significant.
9/12/2020 6:00 AM 0.00 0.0 M M M Very little snow remains on the ground. Warm, with a slight breeze yesterday--snow was melting quickly.
