Temperatures are expected to hit 100° away from the coast this afternoon. If this forecast verifies, it would be the earliest a 100° temperature has been recorded at the North Charleston climate site since records began in 1938. Combined with humidity, this will feel more like 103°-107°. Heat Advisory will be in effect from 11am-8pm. Heat safety is a must today — fluids, shade, rest! More on the heat wave later today.
