DC Forecast for Tuesday, July 24, 2012


Published on by Jason Fouchard

Storms so far today have been keeping to the West of the DC area, for the most part, with numerous Severe Thunderstorm and Tornado warnings issued in Virginia and West Virginia earlier today. However, unstable air is still over much of the DC area, which should allow storms entering the area to continue and intensify.

This is evident by the severe warned storm moving through Frederick southward [UPDATE: The NWS has allowed this warning to expire at 5pm]. The storm should be affecting Montgomery County and DC within an hour.

Isolated thunderstorms, some severe, can still be expected to form throughout the rest of the afternoon and early evening. By sunset, most thunderstorms will have progressed to the south of DC.

The thunderstorms today are forming ahead of the cold front which is moving south towards the DC Metro. This will lead to slightly cooler temperatures tonight and tomorrow, with the high not breaking 90°. Expect tomorrow to be a nicer day to do outside activities with the sun shining brightly over the area.

And you better enjoy the weather outside tomorrow, because Thursday the hot and muggy temperatures return, with highs up around 100°, and the heat index even higher. There is a chance of showers and possible thunderstorms to the extreme northern counties in Maryland along a front Thursday.

On Friday, the front will progress southward leading to more showers and thunderstorms Friday afternoon. These are expected to continue into Saturday and will bring cooler temperatures once again for the weekend. The chance of rain will continue into Sunday and Monday.

However for the moment, you should be keeping a close eye on the weather today, as more severe storms are still possible. The severe thunderstorm watch remains in effect until 8 PM. [UPDATE 6:50 PM: The SPC has cancelled the Severe Thunderstorm Watch for the entire DC Metro Area]
