Discussion

Despite the fact that the center of Tropical Storm Debby will likely not move to the Mid-Atlantic region until the end of the week, its influence around here will actually begin late today and tonight. The combination of an increasingly tropical air mass and an incoming cold frontal system will result in late day and nighttime showers and thunderstorms. Some of the rain will be heavy at times and flash flooding may become a concern during the overnight hours. It turns much cooler for the second half of the week following the passage of the cold frontal system which will actually stall out just to the south of here.

Tropical Storm Debby is now near the Georgia/South Carolina coastal border region and it will meander to a position just off the South Carolina coast by late today and tonight. Some re-intensification is possible on Wednesday while TS Debby is out over the open waters of the southwestern Atlantic and then a second landfall is likely on Thursday somewhere along the South Carolina coast. After that, the tropical storm is probably going to be kicked out to the north and move into the Mid-Atlantic region which likely results in additional heavy rainfall around here from later Thursday into early Saturday.
