MYRTLE BEACH, S.C. (WBTW) — Tonight will be muggy, mild, and partly cloudy. There are a couple of severe thunderstorms in the upstate, but those will fall apart before making it to our area. A brief shower after midnight is possible.

For tomorrow a pop-up storm is expected, but it does look mostly sunny throughout the morning and early afternoon. High temperatures tomorrow will be in the low-90s at the coast and upper-90s in the Pee Dee. The heat index is the real concern.
