DISCUSSION

KEY MESSAGE 1: Dry conditions will persist through the weekend with rain chances increasing early next week.

Ridging aloft will remain the driving feature across the Southeast U.S. through the weekend. Dry high pressure will be situated directly across the forecast area this afternoon then will gradually shift east out into the Atlantic through the weekend. Temperatures will be typical of early summer with upper 80s/lower 90s with the potential for some mid 90s by Sunday and Monday. Overnight lows will gradually warm each night, with upper 60s/lower 70s inland with lower/mid 70s at beaches and Downtown Charleston into early next week.

Rain chances will begin to increase early next week as a weakness develops in the ridge and the area of broad subsidence lessens across the region. This result in a more typical, diurnally driven pattern of showers/tstms from Tuesday onward. A weak cold front could approach from the north Tuesday, but model trends suggest the front may dissipate prior to reaching the South Santee River.
