A quiet week is expected across the southeast as high pressure dominates the sensible weather, with the only exception being the southeast coast.
Showers and storms will be possible tomorrow across the midlands of South Carolina, Georgia, and far eastern portions of North Carolina tomorrow. The front that is currently sweeping across the Carolinas will be pushing east through the overnight hours; however, it will still be close enough to the coast tomorrow to cause afternoon showers and storms. Behind the front, you will notice the drier and cooler temperatures. High temperatures tomorrow will be 5-10 degrees below Sunday for areas west of I-95.
By Tuesday, the upper level trough should be off the coast and nearly all of the southeast will be under the influence of high pressure. Rain chances remain extremely low to non-existent across a large portion of the southeast. Temperatures may actually be a little cooler for your first full day of fall.
Wednesday will be similar to Tuesday, but by Thursday a front off the coast may drift westward back towards the Carolina and Georgia coast. The GFS shows rain showers along the coast on Thursday and Friday. The GFS keeps a majority of the rain right along the coast of South Carolina through Friday, with heavy totals hugging the coast. This will need to be watched and monitored moving forward to see if the front pushes farther east than what the models are showing, or if the front stalls further west than what the models are showing.
For everyone west of I-95 and north of the Fayetteville, Jacksonville area of North Carolina, I expect clouds to begin increasing on Thursday and Friday with northeasterly flow. Temperatures should remain lower with the thicker clouds in the low to mid 70s.
By the weekend, uncertainty evolves with the development of an upper level trough over the plains and an upper level ridge over the northeast. We will need to watch both features as they could impact the weather for the end of the weekend into next week.
