The forecasted storm for this week is still on track, but it looks like the timing will be a bit later, and the precipitation amounts in the models have decreased since I last updated on Friday. That said, there are a lot of precipitation features within this system that could develop in the right place to bring us much more precipitation than the models are depicting, so we could get a nice surprise, but I would not bet on it.
Summary: a strong, cold upper-level trough will move into the area tomorrow (Tuesday) morning, and linger over us for a few days, with periods of mountain snow through Thursday. We will warm up and dry out over the weekend, with our next shot at a storm about a week from now.
Snow Levels: beginning at around 8500ft on Tuesday morning, and lowering rapidly through the day. Temps will likely be cold enough on Wednesday and Thursday for snow all the way to the valley floors.
Snowfall: generally 4-8″ for most of the Wasatch, with 6-12″ in the upper Cottonwoods.
Lake-Effect Wildcard: with a cold upper-level trough this time of year, and a VERY warm Great Salt Lake, there is a good chance of lake-effect snow. If a lake-effect band can organize and sustain itself over an area for some time, totals could be higher. Let’s hope for some magic from our Salty neighbor to the Northwest.
P.S. the winds will be howling this afternoon. Prepare yo’self
