DETAILED FORECAST
THIS EVENING & OVERNIGHT: Heavy rain and storms south of I-70 will decrease into the early evening, Storm Center 7 Chief Meteorologist McCall Vrydaghs said. Areas north will remain dry. It will be warm and muggy with temperatures in the 80s. Because of the amount of moisture in the environment and the nature of these slow moving storms, flash flooding will be a threat. Skies will become mainly clear overnight. Still mild and muggy with lows around 70 degrees.
