NWS, local officials keeping eye on forecast for heat wave next week in Hagerstown region

A heat wave is expected to hit the Tri-State area next week before summer officially arrives. Heat indexes could reach 100 degrees next week, according to National Weather Service meteorologists for the region. The stretch of hot, humid days is forecast to start Monday, though the main concern for heat is expected to be mid to late next week, meteorologist Jeremy Geiger said.
