More Severe Storms, Dangerous Heat In VA Forecast: See Details, Timing

More severe storms are in store for Northern Virginia on Friday, while dangerous heat and humidity are expected to linger through the weekend, according to the latest forecasts.

A heat advisory remains in effect until 8 p.m. Friday for the region, the National Weather Service said. In the D.C. area, temperatures are expected to climb into the upper 90s, with heat index values reaching around 105 degrees.

"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors," the National Weather Service warned. "Take extra precautions when outside, and take action when you see symptoms of heat exhaustion and heat stroke."

Expect high temperatures to remain in the upper 80s to the low 90s on Saturday and Sunday before much cooler air eases into the state by early next week.

The hot, moist air is expected to fuel more severe thunderstorms on Friday. The greatest chance of storms will be between 2 p.m. and 8 p.m., according to the National Weather Service.

The biggest threats accompanying Friday's storms will be damaging wind gusts or large hail.

While Saturday should be dry, shower and thunderstorm chances return late Sunday into next week as a cold front moves through the region.
