Updated forecast on storm

by

I’m expecting snow to develop Thursday across the region temperatures may spike above freezing for a few hours across the south and east but come down quickly once precipitation starts thu an all snow event. One streak of snow moves along I-64 overnight Wednesday night getting into Lexington and Louisville for the Thursday commute around an inch of snow is expected as this streak moves across I-64 by noon Thursday. With temperatures in the 20’s roads will become slick and hazardous quickly.
