9/25 – Payton’s Monday Afternoon Forecast
At the surface, high pressure over the St. Lawrence River Valley extends southwest into east Texas. Aloft, a weak low is centered near the Gulf Coast. The weak upper low near the area will gradually sink southward into the northern Gulf of Mexico as it weakens. This will bring one more day of rain chances a little higher than climatology with most areas in the 40-50 percent range, before falling to 30-40 percent tomorrow as mid level drying starts to build back in. This will lead to a dry forecast on Wednesday.
Mid level drying will continue through Thursday before a strong northern stream moisture-starved cold front through the area Friday and Friday night. Expect little, if any, precipitation with this front. What the front will do is bring drier and cooler air into the area for the weekend. The tropics continue to be quiet for South Mississippi.
