Health officials are warning of dangerous outdoor conditions Wednesday after issuing a heat advisory for D.C., Virginia, Maryland and several other states.

The average high temperature for June 20 is 85 degrees. But by noon we had topped that and hit 93. A thermometer in Crystal City registered at 101 at around 4 p.m.

And Thursday is expected to be even worse.

Many Joggers like Matt Thayer from Denver, got out on the National mall very early this morning, but even that proved difficult.

"It's killing me, the humidity,” Thayer says. “Melting away to nothing."

Multiple cooling centers are opening in the area for people looking to beat the heat.

Kids at a northwest Washington camp, Georgetown Day School, were taken inside and out of the heat.

The extreme heat prompted Metro to lift its no drinking policy. Passengers were allowed to drink water only on trains and buses.

Temperatures will stay very warm tonight with lows in the 70s outside the beltway and{ }to the lower 80s downtown. There could be an isolated thunderstorm tomorrow afternoon, but chances are better that we will see afternoon showers and thunderstorms on Friday as a cold front approaches the area.

The weekend will be partly sunny and very warm, with highs in the upper 80s, but it will be a bit less humid. This forecast is exactly what we would expect for a summer weekend. Summer officially begins with the Summer Solstice at 7:09 pm this evening.
