Widespread Rain and High Elevation Snow

🌧️ Widespread valley rain and high elevation snow are heading our way Thursday night into Friday! Most lower elevations will see 0.10" to 0.50"+ of mostly beneficial rain. Watch out for ponding on the roads and an increased hydroplaning risk! ❄️ Heading into the mountains? Snow levels will drop to 5000-6000 feet by Friday evening. Expect 1-4" of wet snow above 6,000 feet, which could lead to slushy conditions on passes like Homestake (I-90) and MacDonald (Hwy 12).
