Locally, the chance of rain will increase tonight and tomorrow in conjunction with a passing cold front. This front will then turn stationary over the Ohio Valley region, generating showers again on Tuesday.
Elsewhere, the coldest air of the season will briefly settle into northern portions of the Rockies and Plains, with daytime highs averaging up to 30°below normal on Saturday
Looking ahead to the Thanksgiving Holiday Weekend, the 6- to 10-day outlook calls for near- to above-normal temperatures over much of the nation, with cooler-than-normal weather confined to the southern Pacific Coast. Wetter-than-normal conditions are expected west of the Rockies and from the northern Delta into Mid-Atlantic and Northeast. In contrast, below-normal precipitation will prevail over the Great Plains, upper Midwest, and southern Florida.
