A moderate temperature inversion is firmly in place over the Treasure Valley, trapping cold air, while higher elevations undergo a warming trend. Also, some low clouds are persisting along the Snake River and will expand overnight into other parts of the valley by morning. Otherwise, partly cloudy and dry through Thursday. Lows 6-12. Highs mid-upper 20s.
A weak storm on Friday will bring clouds and a chance of light snow showers beginning late Thursday night and lasting into early Saturday. Mountain areas stand the best chance of snow accumulations. In the valley, snow showers might produce a trace to 1/2" of snow.
The storm isn't strong enough to sweep out the inversion. The weekend will by mostly cloudy by dry with high temperatures staying in the upper 20s each day through Monday. Another system next week is expected to allow temperatures to warm into the upper 30s by midweek.
