3-22-21: 2pm Update: Our trough-closed low on the way, but taking a little longer to arrive…
Even though we haven’t seen much snow over the past 24 hours, that has not been the case to our north. Click here for some snow reports.
We are now surrounded by advisories and watches as of 3:30pm from Tuesday afternoon through Wednesday afternoon:

Our next trough-closed low will take a little longer getting its act together than was forecast yesterday. Now it looks like snow/rain won’t arrive until Tuesday afternoon and won’t move out until Wednesday afternoon. Because the best odds for snow will now be Tuesday night, there will be a chance for accumulation in the valley. For the mountains it will be all snow. Between now and then, we will continue to see a chance for snow and rain showers, especially in the mountains. High temperatures will be at their warmest today (mid 40’s) then trend downward the rest of the week under mostly cloudy skies. Lows will remain in the teens to low 20’s. We could see winds gusting to 30mph on Wednesday as the trough moves through.
As our first storm moves through on Wednesday, hot on its heals will be our second trough. By Thursday afternoon, snow comes back into the picture and we can expect another round of rain/snow through mid day Friday. This second storm has the potential to be as wet, if not wetter than the first storm. I’ll get into totals tomorrow, but we could easily see a half an inch of liquid (3-5 inches of snow) for the valley and double that or more for the mountains.
For the valley between now and Wednesday: 0.10-0.30 of liquid and or 1-3 inches of snow that could accumulate Tuesday night.
For the mountains between now and Wednesday: 10-15 inches of snow.
