A system is swinging through the Pacific Northwest and will move straight through southern Idaho Wednesday night into Thursday.
Although there isn't a lot of moisture with this sytem we do expect some rain and snow. Elevations at or above 5,000 ft. will see a coating to three inches of accumulation and elevations above 7,000 ft. seeing 4-8 inches. Most valley locations will see all light rain with some snow trying to mix in. No accumulation is expected in the valleys. The rain and snow will get here at around midnight.
The biggest impact this system will have on valley locations is that it will cool temperatures down and kick up the wind. Highs tomorrow will only reach the mid 40s to low 50s. Sustained winds of 20-30 are expected with possible gusts of up to 40 mph.
This system will pass quickly and by Thursday afternoon/evening most of this storm will have passed and some clearing is possible.
The brunt of this storm will hit areas just to our east and possibly drop eighteen inches of snow in parts of Wyoming and southern Montana.
