12/26 – Payton’s Tuesday Night Forecast

The surface low over northwest gulf continues to track east to the mouth by
tomorrow morning. At the same time, the frontal zone over the Mid
South will track south into the forecast area. GFS and ECMWF models are
showing a high pressure over Iowa with tight pressure from the Mid
South to the Gulf Coast. Flow aloft will remain westerly with mean
relative humidity values remaining elevated through Thursday. As a result, rain
chances will remain in the forecast through this periods.

Upper level flow will become more northwesterly as a clipper
deepens the main trough over the Great Lakes to the Mid Atlantic
states Thursday into Friday. This feature will displace moisture
south of the forecast area Thursday night through Saturday. Will
maintain a dry forecast for this periods with slightly warmer high
temps.

Into the New Year we could have a strong cold front move into the area. Right now there are still plenty of uncertainties with just how cold we will get. )
