Tommy makes sure we measure snow properly… Pic taken 2/22/2022
Tuesday – 22 Feb 2022 – 1:30pm
At Stevens Field the high temp yesterday afternoon was 39 and the low this morning was 28. The peak wind at the airfield in the last 24 hours was 43mph and it occurred around 10pm last night. Winds most of the night were gusting into the 20-35mph range. The Wolf Creek summit peak wind was 52mph at 9:15pm and it stopped reporting shortly after.
Precip in the last 24 hours to around 9am… Most reports were in the 1-3” range but there were a couple of overachievers in the 4-6” range. Wolf Creek reported 9” this morning.
The first wave is still moving through. It doesn’t look impressive on satellite, but Mother Nature’s snow machine is turned on. Cyclonic flow, upslope southwest flow, moisture, and probably the most helpful ingredient right now, cold air advection, are keeping the snow going, especially in the mountains.
The next wave, which will be stronger, will move across our area tonight through tomorrow night. The upper level trough will finally move through Thursday morning.
Thursday night through Saturday… Some models show a weak trough moving through Saturday afternoon and kicking up a few scattered snowshowers over the mountains, while other models show nothing. At this point I think we’ll see a few spotty snowshowers but don’t expect much accumulation.
This afternoon… Mostly light snow will fall on and off in the valley. Heavy snow will continue to fall in the mountains. Highs will be in the upper 20s to mid-30s. In the wind prone areas, winds will peak in the 20-25mph and taper off in the evening. Those of you not getting the winds, consider yourselves lucky!
Snowfall amounts to 8pm…
*** There is still a Winter Weather Advisory valid until 5pm today for the upper San Juan Basin, which includes Pagosa Springs. 1-3” of additional snow is expected. ***
This evening into Thursday afternoon… Expect periods of heavy snow, blowing snow, poor visibility, and bad driving conditions through Wednesday night. The bulk of the snow will be done by early Thursday morning, though scattered showers will persist through the day, especially over the mountains.
Winds… Winds will pick up again after midnight and gust 25-35mph causing periods of significant drifting snow, especially Wednesday afternoon. Winds up at Wolf Creek will consistently gust into the 45-55mph range into Wednesday evening.
Drifting snow… In wind prone areas, I expect 3-5 foot high drifts, and roads will fill shortly after the plow goes through.
Temps… Lows tonight will be in the low to mid-20s. Highs tomorrow and Thursday will be in the upper 20s to mid-30s and lows tomorrow night will be in the low-teens to low-20s.
My snowfall forecast to Thursday at noon…
Valley below 7,600ft: 8-14”
Valley above 7,600ft: 12-18”
*** The Pueblo NWS has issued a Winter Weather Warning for the Eastern San Juan Mountains above 10,000ft valid from until 11am Thursday. It’s for 1-3 feet of snow and winds up to 50mph. ***

Thursday night through Saturday… Clouds will gradually clear Thursday night leading to a cold Friday morning. For the rest of this period skies will be partly cloudy with a few spotty snowshowers over the mountains on Saturday.
Temps… Lows Thursday night will be -10 to 10. Highs will be in the lower to upper 30s and lows will be 0 to 15.
