Another day of high humidity and temperatures that could feel like more than 100 degrees are in the cards for the D.C. area. The only potential break will be a few scattered thunderstorms Thursday afternoon.

A heat advisory is expected to begin for most of the metro area along and east of Interstate 95 at 11 a.m. lasting through 8 p.m.



Storm Team4 meteorologist Doug Kammerer said we can already feel the humidity likely to drive our heat indexes upward of 100 degrees.

“We’re going to see that right on through the morning hours into the afternoon,” Kammerer said. “I’m going for a high temperature in the mid-90s, going 96-97 (degrees) in the city.”

The chance of scattered thunderstorms also increased to 40% from yesterday, with Storm Team4 expecting showers to fall along and east of I-95 during the afternoon.
