If you’ve got last minute Christmas shopping to do this weekend, the weather won’t be of much help.
A low pressure system will develop in the Gulf of Mexico today and strengthen while slowly moving northeast across Florida and off the Southeast Atlantic coast by Monday. Meanwhile, clockwise flow around high pressure centered over the Virginias will assist this area of low pressure in funneling plenty of moisture out of the Atlantic Ocean into Georgia and South Carolina.
At the beginning of December, the area was in a bit of a rainfall deficit, but in the last week, upwards of 7 inches of rain has fallen in some parts of the Central Savannah River Area. This new storm system is expected to bring another 2 to 5 inches of rain Saturday through Monday. The highest rain totals from this system are expected to be south of Interstate 20, and especially heavy in the coastal plain regions of Georgia and South Carolina. No severe weather is expected in the CSRA, but some flooding may occur in flood prone areas. The onset of the rain is expected to be Saturday night, but a few spotty light showers or sprinkles are possible as early as midday Saturday.
If you are traveling this weekend, particularly Sunday, in Georgia, Florida or South Carolina, please allow extra time to get to your destination.
Looking ahead to Tuesday and Wednesday (Christmas Eve and Christmas Day), much drier weather is expected with a return to sunshine. High temperatures will reach the mid to upper 60s on Tuesday (great for Christmas Eve services) and near 70 on Wednesday.
