Scattered Showers & Storms

It doesn't seem like it will ever stop raining, and unfortunately, this trend will continue today as a cold front slowly advances toward the state. This front currently stretches from Minnesota to Fort Smith, AR to the Big Bend of Texas. By late tonight, the front should be just west of the Mississippi River. However, the front will outrun the cut-off low spinning across the central Plains. Instead of heights typically falling in advance of a cold front, heights will actually rise throughout the day as the cut-off low digs southward. It will be interesting to see whether the surface convergence with the front or the warming temperatures aloft will win out today. Either way, this argues for less widespread rain today, but scattered showers and thunderstorms will still develop beginning late this morning. I'm not expecting any severe weather today since vertical wind shear will be much less impressive than yesterday.

Patchy fog is around the area this morning so use caution going to work or school. The fog should dissipate by 9 a.m. and give way to a few peaks of sunshine this morning and afternoon. Accordingly, highs should be able to top out near 84 this afternoon. Showers and thunderstorms should dissipate by 9 p.m., but skies will remain mostly cloudy overnight. Although the chance for rain is not zero overnight, I think we should remain on the dry side. Lows tomorrow morning will be near 71.
