As far as I can tell, this is going to be the longest dry stretch of the year so far. It hasn’t snowed since Wednesday, and there won’t be another significant snow for a bit. But it has been a pretty good winter. The mountains around Utah have slightly above normal snow pack, and we’ve been having small to large storms around once a week.
The latest snowpack measurements across Utah show near to slightly above normal readings. This is much better than this time last year when readings were running at half or less of normal. #utwx #utsnow pic.twitter.com/p8uh4DD42p

This change in pattern is related to the cold weather that is invading the center of the country this week. As the frigid air plunges into the heartland, the winds aloft are blowing nearly due north-south just to our east. This highly-amplified flow is very different than the progressive flow with lots of small disturbances that we’ve seen for the last few months. No wet storms can make it across that obstacle, and we’ll be waiting until that cold air has moved to the Atlantic coast before we can resume our regularly scheduled storminess.
As far as periods of benign weather go, it could be worse. It’ll be cloudy on Tuesday, but the other days will range from sunny to partly cloudy. Temperatures in the mountains will be below freezing (except in the sunniest of spots). The pollution vented out partially today, which is nice, but it should build up again over the next few days.
The date we’re watching for the next storm is Saturday the 2nd. That’s pretty far out there, so stay tuned as we discuss how things are shaping up. Right now it looks like a moist, warmish, multi-day event similar to a few storms we’ve already had this winter. I’ll leave off with the Climate Prediction Center’s graphic showing likelihood of wetness during the first several days of next week. The dry times won’t last forever!
