Partly Cloudy, Warmer

Cloud cover associated with a band of showers to our south kept temperatures in the lower 60s overnight. The rain band is currently located east of I-55 and between Highway 82 and I-20. A very subtle upper level disturbance is causing these showers, but we should remain on the dry side this afternoon. It appears as though clouds will thin out through the morning hours and should allow for enough sunshine to warm temperatures into the lower 70s later this morning. Cloud cover will likely increase this afternoon as an upper air disturbance approaches from the northwest. Still, we should be able to top out near 81 this afternoon.

The forecast for tonight is extremely tricky. It appears likely that a large convective complex will develop across Eastern Oklahoma tonight and move east southeast across Arkansas overnight. The upper level pattern remains more east to west over Mississippi, and I believe this will keep the convective complex across just to our north and west through sunrise. However, a chance of showers can't be completely ruled out early tomorrow morning. The low tomorrow morning will be a very muggy 67. I'll post an update later today if it appears that our upper level pattern will break down enough to allow the complex to move through our area.
