12:55 AM Update:  These storms won't quite tonight More moving south of Warrenton and some more warnings  These storms should stay south DC metro area and are strong storms with heavy rain and gusty winds.  Most tomorrow should be south DC area as finally the heat wave has broken

t8:06pm Update: Here's a link to the Fredericksburg Patch about the damage down there. Couple of quotes as well from people that were affected. Sounded pretty rough but the National Weather Service still believes it was a microburst and not a tornado. Don't feel like that is a diminished hazard, microbursts can contain wind gusts up to 100 mph or greater. I imagine the NWS will send a survey team out there this week.

7:20pm Update: Here's a news story out of Fredericksburg.com about buildings being collapsed. Apparently there were a couple of injuries down there as well but I do not have any concrete information on that. Storms are now crossing the Bay and moving towards Salisbury on the Eastern Shore. I am hoping people know about this storm as they are leaving Ocean City heading back to the D.C. area.

7:14pm Update: It appears some people think a tornado went through portions of Fredericksburg earlier tonight. I was watching doppler and think it was more along the lines of straight line winds, potentially from a microburst. We're sending a crew down there to take a look at the damage and will report on it at 10pm on Newschannel 8 and 11pm on ABC 7.

7:02pm Update: Here's another photo from Mark Ellinwood who tweets as @MADUSWX for the Mid Atlantic. Thanks for the picture Mark!

More damage around the Fredericksburg area

6:56pm Update: I've been seeing some moderate damage in Fredericksburg of structures and homes. Check out this one below from Twitter user @Weatherwarrior1 who works with Weather Warrior Entertainment.

6:24pm Update: It appears Reston in Fairfax County and the Fredericksburg area were hit hard and have power outages to deal with tonight. The bright side of this news is we'll be heading into the next 7 days with temperatures in the 80s, not near or over 100.

6:14pm Update: Strong storms are moving through Calvert and St. Mary's Counties with a ton of lightning and heavy rain in Prince Frederick, MD. This will continue to move south and east towards Lusby and Lexington Park.

The other severe storm will move towards Montross in Westmoreland County in VA and south through the Northern Neck of VA.

6:09pm Update: Nice picture of mammatus clouds from Poolesville, MD sent in from Twitter User @DanielO6_08

6:03pm Update: I've now seen a report of trees down and scattered damage south of Fredericksburg along Jefferson Davis Hwy and Harrison Rd. on Twitter. What are you seeing down there? The strong storm that passed through is now headed through King George County and will affect Southern Maryland and the Northern Neck of VA.

5:54pm Update: A few positive lightning strikes have been in the D.C. area over the past 20 minutes. One hit right along Beach Drive in NW D.C. These are the stronger strikes and make up only 5% of all lightning strikes. You may still want to wait to go outdoors for a while if you're in the D.C. area even though storms are so far south. This lightning is coming from the anvil clouds way up in the atmosphere. There's still enough charge seperation in the D.C. area for a few of these strikes to happen.  

5:24pm Update: Fredericksburg has gotten in on the action with a lot of intense lightning, gusty winds, heavy rain and some potential hail. This will move to the east towards King George County in VA over the next 15 minutes.

The northern portion of that line is moving over Aquia right now in Stafford County east across the Potomac into western Charles County by Nanjemoy.

Trees have been reported down in Reston now as well from the storms earlier. Please send me any pictures of damage to @alexliggitt on Twitter or iwitness@wjla.com.

5:10pm Update: Thanks for the comment below about Stafford being out of power. There is a strong storm headed to Stafford over the next few minutes. A ton of lightning, winds potentially to 70mph and some large hail is embedded in that cell. Here's a picture of it as of 5:12pm.

5:04pm Update: Just had a report of some trees down on power lines in the Woodbridge area. That storm will push east in the next 20 minutes or so.

4:53pm Update: A ton of lightning in the storms currently affecting the Dale City area. That storm will head across the Potomac into Charles County near Marbury.

Another strong storm with a lot of lightning is in Southern Fauquier County moving towards Stafford County in VA. This will approach I-95 over the next 15 minutes.

Another heavy line of storms will move back into the Warrenton area in the next few minutes.

Finally, a severe storm is located around Winchester moving east back into Clarke County which has already had a few rounds of storms today. 

4:37pm Update: It appears the main threat for storms will be south of the D.C. Metro, which is good for people in MD still without power. Strong storms are all over parts of Virginia from Frederick County to Fairfax County and south through Stafford. These storms will move across the Potomac and into Southern Maryland and the Northern Neck of Virginia as well.

4:27pm Update: Storms continue to roll through Virginia and D.C. Let us know if you lose power at @alexliggitt and @steverudinABC7 on Twitter and we'll be sure to retweet your outage. Check Dominion Power's Interactive Outage Map here.

4:20pm Update: Strong storm affecting the western portion on the Beltway now moving into Arlington and Alexandria. Tons of lightning in these storms today so stay inside if you can!

4:12pm Update: Severe storm now moving inside the Beltway towards Arlington, Alexandria and D.C. Time to get indoors! Another severe storm is continuing to move east along I-66 in Fauquier County. It is moving into Prince William County at this time and will move southeast. Winds are possible up to 80 mph in this potentially destructive storm. Watch out if you're in Haymarket or Warrenton.

3:53pm Update: Severe storms moving into Fairfax and Montgomery Counties. Another strong storm is located in Fauquier and Loudoun Counties moving east along I-66.

There is a ton of instability in the D.C. area so these storms shouldn't have any problem continuing east.

3:38pm Update: Here is the storm risk graphic that we are using today. Damaging winds are the most likely along with some large hail. Lightning also is a big threat as of the latest radar image over 325 lightning strikes have been detected in the D.C. area.

3:12pm Update: If the storms weren't enough, Reagan National broke the record high of 100 set back in 1993. It's currently 102 and feels like 110. Might as well stay inside until after the storms exit by this evening!

3:02pm Update: Numerous thunderstorms have developed along and west of the Blue Ridge mountains. There is one strong storm east of the Blue Ridge in Loudoun County headed towards Leesburg. Damaging wind gusts appear possible in this storm. Take cover in a safe place in your house until the storm clears your area.

Another severe storm is in Frederick County, VA and headed into Clarke County, VA and will affect Berryville, Bluemont and Delaplane. Winds to 60mph are possible in this storm.
