The National Weather Service issued an Excessive Heat Warning on top of the Heat Advisory that’s in effect until 8 p.m. on Thursday.
Heat index values (the temperature it actually feels like) could get as high as 110 degrees.

The heat index is likely to hit 106 degrees Thursday, 110 degrees Friday, and 108 degrees Saturday, according to NBC4 at 1 p.m.
When the heat combines with the humidity, NoVA could see the risk of severe thunderstorms from about 3 p.m. to 7 p.m., said NBC4 meteorologist Chuck Bell.
Bell said in his morning forecast that there aren’t necessarily going to be a lot of storms, but those isolated storms could bring heavy rain and high winds.
According to Bell, there is a chance that Thursday’s temperature could break the record of 98 degrees at Dulles International Airport set in 1993.
The last time the region saw a stretch of weather with temperatures reaching 100 degrees, Bell said, occurred in 2016.
