Precipitation summary… Wolf Creek reported 10” of new snow this morning. Snow amounts in the valley were mostly in the 1-3” range. The winners were north of town with 4.7” to 7”.
Rest of today… Storm 1… A vigorous cold front will move through in the early afternoon. We’ll see occasional blizzard conditions ahead of the front.
What’s the criteria for a “blizzard”?
– Winds: sustained or frequent gusts 35mph or greater – check!
– Heavy snow, blowing snow, and poor visibility: ¼ mile or less visibility for 3 hours or more – We’ll cut this one close but will see periods of ¼ mile or less.
Snow… We’ll see a one to two hour burst of heavy snow, blowing snow, white-out conditions, and possible thundersnow late morning into early afternoon as the cold front moves through. Then we’ll see a one to two hour lull behind the front with scattered snowshowers. Snowshowers of varying intensity will continue to move through into the evening. It will snow heavily up at Wolf Creek all day.
Winds… 40-50mph winds will persist into the evening. Peak gusts will be 55-60mph. Winds will decrease some Wednesday night but still gust into the 20-30mph range. Winds in the mountains will consistently gust 60-70mph early Wednesday morning to late Wednesday evening and peak gusts will be 80-90mph.
Temps… Temps will hover in the upper 20s to low 30s until the cold front moves through noon to 1pm. Behind the front temps will drop rapidly 5-10 degrees and we’ll be in the teens by sunset. Lows Wednesday night will be in the mid-single digits to mid-teens.
*** There will be a one to hour burst of heavy snow, blowing snow, white-out conditions, and possible thundersnow late morning into early afternoon. ***
*** Winds will gust 40-50mph until 9pm this evening. Winds will peak 55-60mph 11am-3pm. This will cause significant blowing snow, white-out conditions, and possible power outages. ***
*** Winds in the mountains will consistently gust 60-70mph to late Wednesday evening. Winds along mountain ridges could peak in the 80-90mph range roughly 10am to 3pm. ***
*** The Grand Junction NWS has issued a WINTER STORM WARNING for the San Juan River Basin, which includes Pagosa Springs, for a total of 4-10” of snow and winds 45-55mph with potential for higher gusts valid until 5am Thursday. ***
*** The Pueblo NWS has issued a BLIZZARD WARNING for the eastern San Juan mountains which includes Wolf Creek Pass for total accumulations of 1-3 FEET of snow and winds up to 80mph valid until 5am Thursday. ***
*** The Colorado Avalanche Information Center has issued an AVALANCHE WARNING valid until midnight tonight. Large and dangerous avalanches will be easy to trigger. *** I expect this warning to be extended.
My snow forecast between 10am to midnight…
Thursday through Friday morning… Storm 2… This storm won’t be as organized and will have less moisture. There will be a bit of a lull Thursday morning, but clouds and scattered snowshowers will persist. Snow will increase slightly Thursday afternoon and into Friday morning. Most of the snow will be done by noon Friday, but a few scattered snowshowers will persist over the mountains through Friday afternoon.
Winds late morning to late afternoon both Thursday and Friday will gust 20-30mph.
Temps… Thursday highs will be in the mid-20s to low 30s and lows will be in the low teens to low 20s. Friday will be a little warmer with highs in the low to high 30s and lows in the low teens to low 20s.
My snow forecast…
Saturday… There will be a lull, but mostly cloudy skies will persist and a few spotty snowshowers are possible over the mountains. The lucky spots in the mountains could get an inch.
Sunday… The next system will move through with more clouds and another round of snow. This storm will move through pretty quickly and won’t have much moisture. Snow amounts don’t look impressive.
My snow forecast…
I’ll probably do a quick Facebook post after the cold front moves through. My next thorough post will be tomorrow morning.
