The first day of February is going to be a cold one! Temperatures will drop even lower over the next few days, so make sure you're bundled up before you head out in the mornings.
The next weather system will cross Utah later tonight and tomorrow. It's still very dry, so the mountains will only get some light snow. The best chance of snow will actually be in Tooele and Skull valleys, where lake effect is possible later tonight and early Wednesday. If it does develop, an inch of snow is pretty likely on the valley floor, but there's a chance there could be 2-4 inches. Some locations could get even more if snow is persistent and stationary.
Gusty winds will also be possible near the canyons of Washington County tonight and early tomorrow.
