Hottest Weather All Summer May Be on Way

The next few days may bring the most humid weather D.C. has seen all summer.

Stifling heat moved into the region Thursday. With the heat index, it could feel like 105 degrees or hotter. 

A heat advisory has been issued for the D.C. area until 8 p.m. Thursday. The heat advisory likely will stick around through the weekend.

"It's going to be an ugly shade of humid today and all the way through this coming weekend," Storm Team4 meteorologist Chuck Bell said. 

The high temperatures may affect your commute.

Due to the high track temperatures, Metro trains are operating under a 35-mph speed restriction at all above-ground stations, Metro said Thursday. System-wide delays are possible.

Storm Team4 has declared Weather Alert Days for Thursday through Sunday.

On Friday, the temperature is expected to peak at 94 degrees, with a 20 percent chance of rain.

Temperatures likely will be at their highest on Saturday, when we could see 96 degrees and an isolated chance of showers.

On Sunday, thunderstorms are possible in the evening, while temperatures may lower slightly to 94 degrees.

The previous heat wave was record-breaking for D.C., with 35 consecutive days over 70 degrees. The streak ended August 9, after temperatures dipped into the 60s.
