Hot Weekend Ahead for the South

If you live in the Deep South or Texas, get ready for an early taste of summer this weekend as above normal temperatures are expected across a good portion of the area. High pressure building into the mid levels along with a brisk southerly wind flow will allow temperatures to rise through the weekend. Across South Texas today heat index values may top out near to slightly above 100F.

A wide swath of excessive heat is expected this weekend into the middle of next week as a strong upper level high builds across a good portion of the Deep South. Both today and tomorrow we expect heat index readings to top out near or above100 degrees across the central and western Gulf as well as into portions of the Southern Plains. It’s even possible that heat index values may rise above 105F over the middle to lower Texas coast tomorrow. Hot and humid weather will continue to effect much of the Gulf Coast and Southern Plains on Sunday with above normal highs expected over parts of the Southeast as well. Heat index values in excess of 100F are anticipated, and the Texas Gulf Coast could see heat index values up to 105-110F.

Hot weather will continue into early next week across the Gulf Coast, Southern Plains and Southeast. Heat index values could possible reach in excess of 105F across the central and western Gulf Coast. Image: ImpactWeather

This will be the first significant heat event of 2010, but as we all know we’re just getting started. The first official day of summer in the Northern Hemisphere isn’t until June 21, 2010 at 7:28 am EDT…which is almost three more weeks from now!
