This Afternoon: Hot and Humid, Storms Possible

Highs: Around 100 | Heat Index: 105+

Lows: 70s | Precipitation: 50%

Thursday: Mostly Cloudy, Storms Likely, Not as Hot

A Severe Thunderstorm Watch is in effect until 9 p.m. Check out the details of the watch here. A frontal system is approaching the D.C. area from the northwest and will bring the chance for storms through the afternoon and continue overnight.

Temperatures near 100 degrees and dew points around 70 will make for large amounts of instability and could lead to severe weather in the form of damaging winds in some of these storms. A Heat Advisory is also in effect until 9 p.m. for the D.C. area.

A ground stop has temporarily been put into place at all three D.C. area airports due to the threat of severe weather, according to the FAA.

Scattered showers and storms will persist as night comes with lows in the 70s. Thursday and Friday will continue to see the potential for showers and thunderstorms. Some may produce some heavy rainfall and there is the potential for a few inches of rain by Friday evening. Temperatures will drop back into the low 90s tomorrow and mid 80s Friday, so at least cooler air is on the way.
