Surface high pressure will build across the area, with light winds and cool temperatures today.
Winds will become southerly by tonight, with warmer overnight lows on Thursday.
Next cold front will move across Kansas on Thursday, with gusty south winds and more clouds ahead of the boundary for Eastern Oklahoma and Western Arkansas.
To the south, a warm front will approach the red river by Thursday evening, and this could be a focus of some elevated storms late Thursday night.
The better chances for storms will be across Southeast Oklahoma.
On Friday, the cold front will move south across Northeast Oklahoma, and there should be a tight gradient with temperatures falling into the 40s across Northeast Oklahoma and Northwest Arkansas on Friday afternoon with mid-60s to lower 70s across Southeast Oklahoma.
Widespread rain and storms should develop by Friday afternoon, with a chance for some strong or severe storms.
The main threat will be large hail. Temperatures fall below freezing by or shortly after midnight on Saturday morning across Northeast Oklahoma, and any ongoing precipitation could end or transition to flurries or even some sleet.
Accumulations will be light so any impacts will be minimal.
Saturday will stay cool, before a warmup on Monday and Tuesday.
