2:09 p.m.: The gust front preceding the thunderstorm moves over Tysons Corner, Va. The Tysons Galleria is visible in the foreground. This photo was taken facing east.

About 1:45 p.m. on Monday, I received a call from my son who said our neighborhood pool in Oakton, VA had closed due to thunder and he and friend had taken cover from the approaching storm in our house, which is a short walk from the pool. He said the storm had not yet reached Oakton and they were safely inside. I work just to the east of Oakton, in Tysons Corner, and I could see the clouds approaching from the northwest.

Within moments, dark, swirling clouds associated with the thunderstorm's gust front moved overhead, providing a strong warning of the approaching storm. About 30 minutes later, the core of the thunderstorm hit Tysons Corner, blasting the area with heavy rain and strong winds.

The photos that follow show the progression of the storm through Tysons Corner and are time stamped. The last photo is of storm-related damage in Fairfax, Va.

Love it.
We were driving thru the Tysons about 40 minutes before these were taken. It was obvious that there was a serious incoming storm & we were grateful to make it home before the skies opened up. Received about 1.5 inches of much needed rain in Centreville.
Looks like that will have to do for a while, as no rain is in the forecast.
Thanks for pics!

in the last pic, is the black inside the tree rot, or burn from being struck by lightning?

Thanks for the great pics!

Sara, the tree was hollow and stained black on the inside. I don't think that was from lightning.

Writing from IL, that looks like a wall cloud with some decent rotation and not just a gust front.

That might be a funnel cloud over Tysons.

I did see a nice "beavertail" with the earlier Tuesday night storm a week ago...it was at middle-cloud altitude.

There was no rotation in the storms yesterday and a wall cloud would be at the backside of a storm in most cases. From reports and seeing myself plus in these pictures the gust front was pretty ragged and filled with scud clouds, which may be why it looks like that.

The storm brought a huge oak down on our house in Fairfax too. Major damage to the house, but thankfully no one was hurt. We have multiple, healthy trees down in a small path from our back yard through several of the neighbors. Many of the trees were snapped off right in the middle, but a block away there weren't even branches on the ground. Someone suggested a microburst...? Is that a possibility with this storm? It was the most violent wind I had ever experienced for a few minutes there, I was sure we were being hit by a tornado. Everything outside looked like it was made of rubber it was tossed around so much.

ucayaliblue, were the trees blown down in the same direction? It is possible that the winds were related to a microburst, see http://en.wikipedia.org/wiki/Microburst.
