Severe weather warning for the Washington, DC area until 10:00 p.m.

* Overheat warning until 8 p.m. | storm warning until 10pm *

The combination of heat and humidity has pushed heat indices in the Washington metropolitan area above 105 degrees for the third day in a row. The moist air could trigger some severe thunderstorms in the region Wednesday evening.

The National Weather Service has issued a severe weather warning until 10 p.m. This means the ingredients for severe storms are in place and you should keep an eye on the weather. While severe storms are not guaranteed for any particular location, they can bring damaging winds in addition to heavy rain and lightning. There is also a small chance of a tornado in the area. If a severe weather warning is issued for your location, seek shelter immediately.

The storms will bring much-needed rain to the locations where they hit and help reduce some of the heat and humidity on Thursday.

Until tonight: Toward the evening, a broken line of storms will approach from the west. It should reach the Interstate 95 corridor around sunset. Although it should pass quickly, brief torrential rain, lightning and perhaps some wind damage or an isolated tornado are possible. When the storms dissipate, lows will be between 70 and 75 degrees Fahrenheit.

Watch the Current weather conditions in the Washington Post.

Tomorrow (Thursday): Behind the weak cold front fueling the storms comes a little less humidity. Sunshine dominates as highs are likely to reach 90 degrees and below 90 degrees.

Storms could produce one or two tornadoes: The weather system affecting our region Wednesday afternoon and evening includes the remnants of Hurricane Beryl, which passes just north of us and has already spawned tornadoes in New York State. We are usually cautious when the swirling wind fields of these larger systems approach. This tends to increase wind shear (change in wind speed and direction) in the lower atmosphere and can contribute to the creation of small areas of increased rotation during thunderstorms. We believe the tendency for weak tornadoes is greatest toward the Mason-Dixon line and particularly in Pennsylvania, but cannot rule out a fast-moving tornado near Washington.
