A few thunderstorms may develop on Monday afternoon and into the evening hours, possibly causing in flooding or damaging wind gusts west of the Blue Ridge Mountains and south of Route 50, according to the NWS forecast.

Monday will be mostly sunny with a high of 93. As clouds begin to move into the region during the evening hours, temperatures will drop to around 69 degrees.

The combination of hot weather and high humidity from Tuesday afternoon to at least Sunday afternoon could result in heat indices above 100 degrees, according to NWS.

"At least 135 million people across the eastern United States and parts of eastern Canada will experience a heat wave this week," according to AccuWeather's forecast. "The peak of the heat wave for most of this zone is expected around the same time as the start of astronomical summer, which takes place on Thursday, June 20, at 4:50 p.m. EDT."

NWS shared the following precautionary information on how to prepare for a heat wave:

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.
