If you do not like these above average temperatures, you can look forward to a pattern change; however, there will be an increase in humidity and rain chances. Flash flooding will be possible by the end of the week and over the weekend.
The heat remains for your Monday; however, you will begin to notice the humidity values increase. By Tuesday an upper level disturbance will be located in the Gulf of Mexico, and the Bermuda High will help to pump moisture into the Carolinas. This will lead to afternoon showers and thunderstorms.
The upper level disturbance is expected to stall across the Gulf Coast, and this will help to funnel moisture across the entire southeast. Afternoon showers and thunderstorms are expected to continue through your weekend.
Locally heavy rain is expected with these storms. Many areas will see 2-4 inches of rain through Sunday, with some areas receiving higher amounts where thunderstorms train over the same area. Flash flooding will be possible with the slow moving nature of the storms.
