Cold front bringing valley rain & mountain snow overnight

The daily forecast from Idaho's largest, most experienced team of meteorologists.

BOISE, Idaho — Light showers are starting across southern Idaho and eastern Oregon, and they're expected to increase ahead of a cold front that will move through mainly overnight. So, likely that many of us are waking up to soggy conditions in the valleys and a few inches of fresh snow in the mountains.

Temperatures warmed into the upper 50's as a weak warm front drifted through today. Mountain areas got into the 30's and low 40's while light snow accumulated. Ski areas saw anywhere from trace amounts up to 4 inches.

A storm system off the west coast will continue its slow trek inland along with the associated cold front. Light snow accumulations possible today above 5,000' and then a steadier snowfall expected overnight. 5-10" of accumulation is possible by Thursday evening above 6,000', with an inch or two possible in mountain valleys. Across the Snake Plain, 1/3" of rain or more is possible in the Boise area from Wednesday night through Thursday morning.

On Friday, the storm system digs south along the west coast and then moves eastward, taking most of the precipitation with it. Some lingering showers are possible along the ID/NV border Friday into the weekend as southern Idaho will remain on the northern periphery of that slowly exiting system.

Easter weekend is looking mainly dry in SW Idaho with temperatures rebounding to near 60°, with a stray sprinkle or two possible on Sunday, especially towards the Magic Valley.  Early next week, spring sunshine returns and temperatures warm, with Boise back up to 70° by Tuesday.
