MYRTLE BEACH, S.C. (WBTW) – Muggy conditions and mild temperatures top headlines for tonight with lows only in the mid-70s. There is a small chance for an isolated storm inland after 10 p.m., but any storms fizzle out before hitting the coast. Highs for tomorrow will be in the 90s with the heat index approaching 100 degrees – a partly sunny start before a more active evening.
