Cooler than normal temperatures hold through Friday, when a warm front lifts into the region and brings showers and a few thunderstorms.
After a few days of cooler weather to end the work week, heat and humidity is forecast to return this weekend and last into early next week. Right now, it appears that Sunday and Monday will be the hottest days with heat index values of 100-105+ possible each of those afternoons/evenings.
