Oppressively Hot and Humid / August 13

Partly sunny very hot and humid. High temperature of 100 with heat index values close to 115. Heat advisories and warnings have been posted for entire area.

Later this afternoon: Scattered showers and thunderstorms redeveloping around the area. Storms will be capable of producing torrential downpours, gusty winds and dangerous cloud-to-ground lightning.

-This is all due to a Bermuda high sitting off the eastern US coast near the Carolines. The return flow is Southwesterly which is helping to move in warm, very humid air from the SE states and Gulf of Mexico into our area. Sea-surface temperatures off the SE coastline and the gulf of mexico are in the lower to mid 80’s. This high is forecast to remain in place over the next few days.
