8/17 – Rob’s “Friday-Eve” Afternoon Forecast

As an area of high-pressure moves close to the N’tern, daytime heating has temps in the low 90s with the “FEELS LIKE” temps around 107 degrees…

Upper level analysis shows a somewhat weak are of high-pressure centered over the northeastern Gulf of Mexico while a trough races northeast across the upper Mississippi River Valley towards Canada. Subsidence/compression from the high pressure aloft will limit t-storm coverage this afternoon compared to previous days. Fewer t-storms in general, means more opportunity to warm closer to the mid 90s. Very humid air coupled with daytime and compressional heating will make for DANGEROUS HEAT this afternoon/tomorrow with the HEAT INDICES between 105-110 degrees. A HEAT ADVISORY is in effect through 7 p.m.

A return to a more typical wet mid-August pattern is expected over the weekend as a cold front will track west-east north of Hattiesburg. Rain potential will return above 50% this weekend into early next week.
