Wednesday Forecast: Tracking afternoon rain, snow and mix

KENNEWICK, Wash. — It will be very cold and dry this Wednesday morning, but that will change as a winter storm is moving into our region this afternoon bringing rain, snow and snow mix. 

Temperatures are low in the 20s and will drop again in the evening. Bundle up and plan ahead for some morning frost on your windshields both Wednesday and Thursday. The Futurecast shows rain, snow, and mix in the Columbia Basin by 3 p.m. today and will continue into the evening as snow levels are expected to drop to 800 feet in the Basin. Snow accumulations in the lower levels will be light to none. The snow chances could drop for the Tri-Cities and Walla Walla depending on if the temperatures warm up.
