Friday night's storm system also welcomed a winter wallop to the Central and Boise Mountains! A Winter Weather Advisory kicked off Friday night at 11pm and is expected to end at 5am Sunday morning. During this time, 3-6" inches of snow is expected in the mountain valleys while 1-2' of snow is expected at 6,000' and above in the Boise and West Central Mountains as well as the Camas Prairies.
🚨 The National Weather Service emphasizes hazardous road and driving conditions on Highways 55, 21, and 20 on Saturday night. Roads could present with difficult-to-impossible conditions. Experts advise local travelers to prep for emergency situations by keeping flashlights, food, water, and blankets in their vehicle.
A Winter Storm Warning enters the mix at 2am Saturday and is expected to end at 5am Sunday morning. Between 5-10" of snow is expected at elevations below 7,000' and closer to 1' in the Ketchum area. Throughout the greater Sun Valley region, a whopping 10-14" is expected above 7,000'.
Lingering inversion conditions should have completely scoured out by Sunday afternoon introducing sunny skies and the atmosphere returning to warmer valleys and cooler mountains. Monday evening into Tuesday morning another system briefly visits the Treasure Valley followed by high temps returning to seasonal norms and partly sunny skies through Friday! 😊
