8/17 – Rob’s “Dangerous Heat” Thursday Forecast

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 today 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 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.
