After a nice start to you Wednesday, clouds have been on the increase and precipitation is moving into the area. Snow started in the McCall area just afternoon and will increase into the night. I expect 4"-6" of snow in McCall by sunrise Thursday. Snow levels will rise to 4500ft in central Idaho with mix precipitation and rain falling below that.
In the Treasure Valley I expect periods of rain through sunrise Friday but the first part of Thursday may remain mostly dry & mild in the valley. The western valley near Ontario will have the most precipitation with Boise potentially seeing up to a half inch of rain. Along the Snake River from Murphy south and east I do not expect much precipitation at all due to rain shadowing from southwest winds blowing down the slopes of the Owyhees which dries out the air.
For the mountain of central Idaho, snow totals through Friday morning could range from up to 8" in McCall and other areas at 5000ft to 10"-17" in the ski areas such as Bogus, Tamarack, and Brundage and other areas above 6500ft.
We will see a break from the precipitation Friday and Saturday with comfortably mild valley temperatures topping 50. Another round of valley rain and mountain snow will arrive Saturday night lasting through midday Sunday. Another 5" of snow is possible in the ski areas with this system.
