Friday will be the driest day but with lingering clouds at times and just a 20% chance of an isolated shower. Temperatures will remain in the lower to middle 80s.


A surge of very high humidity and tropical moisture will be funneled into the Carolinas starting Friday night and lasting into early next week. The result will be periods of showers and thunderstorms with several rounds of heavy rain looking more likely. Rain chances on Saturday have been increased to 70% and Sunday’s rain chances have been increased to 60%.
