TLDR: A mild air mass will give way to cold polar air and a moderate powder drop Tuesday night. Scroll down for an initial snowfall probability forecast.
One-Month Probability Forecast
It seems out of the norm that a series of big powder dumps isn’t in the extended forecast. One storm this week will be followed by a period of low chances for a powder day. The next month, however, may favor wetter-than-normal precipitation according to NOAA’s CPC climate outlook:
Though from my experience these outlooks tend to provide less useful information than we ever expect. In this case, there’s about a 60% chance that the SLC area will receive more precipitation than is normal for the next month—a 40% probability for equal-to- or below-average precipitation—according to climate models. These aren’t incredible odds if you ask me.
Looking at the more reliable short-term forecast, we see one big system heading toward the interior west as the week carries on.
Daytime temperatures at ski resorts begin relatively mild (around or just below freezing) through Tuesday night. Some instability today (Monday) and Tuesday may allow light snow showers or overcast to exist at high elevations.
The mild early-week air mass will give way to cold polar air in time for the next powder drop. A moderate snowstorm Tuesday night will usher in unseasonably cold air that will remain over a few days.
You can expect a period of heavy precipitation with the arrival of a cold front Tuesday morning, but altogether this is a quick-hitter. This storm should drop a nice layer of fresh powder overnight for the mid-week crowd, and then another thin coating throughout the daytime.
The snowfall forecast is still uncertain. Here’s mine, just to give you a sense of the range of possibilities for this event at Utah resorts.
So still some uncertainty heading into the next storm, and then quite a bit more uncertainty reserved for next week. My suggestion is that you brace for a cold powder day Wednesday, then hold your dice until late this week when the day 5+ forecast may become clearer.
