For those still without power following Friday night’s storms, the heat could become an added concern Sunday afternoon. Temperatures near 100 degrees will make it important to stay hydrated and find a cool place if needed.

Expect sunny, hot weather Sunday with highs in the mid-to-upper 90s, near 100 degrees in some areas. Drier air and high pressure will limit rain chances and keep temperatures just below extreme levels.
RAIN CHANCES REMAIN LOW
A weak disturbance moving inland from the Gulf could bring a few isolated showers or thunderstorms to the Coastal Plains Tuesday and Wednesday.

Most of these storms should remain close to the coast, although an isolated shower could attempt to move farther inland. Any showers that develop will likely be brief and provide little meaningful rainfall or relief from the heat.
EXTENDED FORECAST
Hot and mostly dry conditions are expected to persist through much of the upcoming week, with highs generally in the 90s. By next weekend, the persistent ridge of high pressure may begin to weaken, potentially allowing a more active weather pattern to develop as winds turn more northerly.
