Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Clouds linger with some clear skies at times as a weak low travels South of the area tonight. Northwest winds will usher in much colder air by dawn with temperatures near 0 by am. Tomorrow through early Wednesday high pressure will build in keeping skies clear but with fresh snow on the ground temperatures will fall below zero both Monday night and Tuesday night. During the days temperatures will be hard pressed to get into the teens. These temperatures with light winds will cause for cold wind chills as low as -15 at times. Southerly flow will return ahead of an approaching front on Thursday getting temperatures briefly above freezing with some melting. Thursday night and Friday the front will bring snow showers and colder air back for the Presidents Day weekend.
Long range: Models continue to hint at some milder air next week as a trough digs into the West Coast and a ridge may build East.
