A coastal storm moving southeast across Nevada spreading some precipitation into southern Idaho. Snow showers began early in the morning for eastern Oregon and continue to spread into the lower Treasure Valley and southwest Idaho. Southeastern Oregon, Owyhee county and southern Twin Falls county will be in the bullseye of this system, with 2-5 inches of snow accumulation. Elsewhere, amounts will be minimal and generally under an inch.
Temperatures warm into the mid to upper 30s in the valley, so snow will mix with rain and any accumulation will remain confined to grassy surfaces. However, wet roadways will lead to a slick evening commute. Overnight temperatures dip into the 20s resulting in icy start to our Thursday. For the Magic Valley, snow showers arrive later this evening lingering into Thursday morning with up to an inch of accumulations. Slippery roads can be expected for Thursday morning.
High pressure will strengthen following today's system leading to areas of dense fog Thursday morning. Temperatures climb into the lower 40s on Thursday and Friday. A burst and rain and snow will arrive Friday morning ahead of a cold front. A strong northwest breeze picks up into Friday evening.
A more potent storm arrives into the weekend. The storm's origin is the Gulf of Alaska, so it will drag in very chilly air with snow levels dipping to the valley floors. By the end of the weekend, 1-3" of snow can be expected for the valley and 6-12" above 5000 feet.
