After seeing the potent line of storms form west of the mountains moving east towards D.C., we quickly scrambled to get all of the necessary information out before clicking a few buttons to record a time lapse! Check it out here.

Did you happen to see it? If you did and took any pictures or video, feel free to share them to our Stormwatch 7 Facebook page!

Hottest stretch so far this year looks to continue into September

After a hot end to August, the heat doesn’t want to go anywhere for the beginning of the month. Check out the 7-Day forecast here. Tuesday through Saturday all appear like they will at least be close to the 90 degree mark, with the hottest day for the remainder of the week Tuesday. Oddly enough, Reagan National Airport hasn't recorded four days in a row with highs at or above 90 degrees this year. The 15th through 21st of July 2013 was the last time we've experienced a prolonged period of high heat, with 7 days in a row at or above 93 degrees.

Last September also started off on a hot note, but beyond the first few weeks there was a nice cool down with a long stretch of days in the 70s. The average high is 84 degrees to start the month, but falls to 74 degrees by the end of the month.

90 degree days as of September 1

Temperatures should get back near normal come Sunday as cooler air moves in after a cold front. For the year, D.C. is still below the normal number of 90 degree days, with 19 as of Monday, compared to the 28 we were at by September 1st in 2013, and compared to the 36 average D.C. typically records in a year. With the recent hot summers, however, this is nothing compared to the record 67 90-degree days in 2010 or even the 56 in 2012, so at least it has been nice!

What about storm chances the rest of the week? After a stormy past two days in parts of the area, a cold front will move into the region late Tuesday bringing an additional chance for afternoon storms. A break in the action will be likely Wednesday and Thursday before chances return Friday in an isolated nature and more widespread action with a potent cold front on Saturday.
