Severe storms crossing D.C. metro area

By Capital Weather Gang

Live NWS warnings & CWG alerts
Fed by CWG's @dcWeatherAlerts. See warning map and radar below.
Full warning text: DC | MD | VA.

4:50 p.m. The Tornado Warning for some eastern suburbs has been canceled. Additional storms continue to drift south and east mainly across the southern half of the area. While severe weather remains a threat, we should be transitioning away from that soon as the atmosphere continues to stabilize thanks to the storms that have passed through.

4:30 p.m. A Tornado Warning has been issued for our far eastern suburbs as the storm which caused damage across portions of the area continues to move east. If you're in Anne Arundel, Prince Georges and Calvert county, take cover now. This storm should head over the Bay shortly. Additional storms still moving east across the area are generally weaker than the first batch, but some additional severe weather is still possible. A line moving toward the area from West Virginia appears to be weakening.

Showers and storms should gradually shift south and east over the next few hours, with most of the immediate metro area probably pretty quiet by around 7 p.m. onward.

Monitor severe warnings issued by the National Weather Service and radar on our Severe Weather Tracking Station below. Check out our full forecast through the weekend. Keep reading for earlier updates and stay tuned for more this afternoon.

4:00 p.m. update: The strongest storms are now moving into central and southern Prince George's County and northern Charles County, where Severe Thunderstorm Warnings are in effect until 4:45 p.m. West of there, new warnings have been posted for Fairfax, Prince William and the District, also through 4:45 p.m., as a new line of storms approaches and moves through over the next hour. The National Weather Service reports a 69 mph wind gust in northwest Arlington just before 3:40 p.m. Montgomery County is the quite spot right now, with storm activity limited to the southeastern edge of the county. From our Twitter followers...

@libby21: "Practically a monsoon in College Park right now."
@resqgal: "Alexandria has been getting slammed for the past 10 minutes. Very high wind. Loud thunder."

3:30 p.m. update: Severe thunderstorms that moved into the area from the west are now reaching the District. These storms continue to carry the potential for damaging winds near or over 60 mph. Twitter follower @T2Va says: "Northwest Arlington constant (loud) thunder, frequent lightning, steady rain." Severe thunderstorm warnings in effect for the western suburbs and the District until 3:45 p.m. should shift east/southeast shortly. Meanwhile another area of severe storms to the southwest has prompted warnings in southern Fauquier, Prince William and Stafford counties.

3:00 p.m. update: A severe thunderstorm is now in central and eastern Loudoun county and starting to impact parts of western Fairfax county. Twitter follower @vtjawo says: "Some heavy bands of rain are beginning to move through Reston" This storm should reach the western beltway in about 30-45 min and the District in 45 mins to an hour. A Severe Thunderstorm Warning is in effect for much of the western suburbs and the District through 3:45 p.m. Strong winds of up to 60 mph are possible along with torrential rain and dangerous lightning.

2:30 p.m. update: A broken line of storms is developing just west of Loudoun county and extends into central western Va. These will probably reach some of the western suburbs (e.g. eastern Loudoun County) in about an hour and, may reach the beltway in about two hours. A Severe Thunderstorm Warning has been issued for parts of Loudoun (south and west), Fauquier (north) and Prince William (north) until 3:15 p.m.

From 1:30 p.m.: For the second day in a row, a Severe Thunderstorm Watch has been issued for the entire metro area, this one in effect until 10 p.m. While yesterday's storms weakened as they approached and moved through, a more unstable atmosphere today could mean a better chance of some severe storms, though the most frequent and intense activity may end up just south and east of the metro area. From NWS:

HAIL TO 1.5 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE

As of early afternoon, isolated thunderstorms were developing in northwest Va. Storms may become better organized and start moving into the metro region between 2:00 p.m. and 6 p.m.

Any signs of a potential for rotation?

Great! On the day I find and purchase the first Sam Adams Octoberfest of the season, the power will go out, the beer will spoil and the chaos of a disintegrating society will take place. Summer lovers, I hope you revel in your favorite time of the year :)

On a side note, I was at Yankee stadium when A-Ro(i)d hit his 600th homer. Great thing to witness!

Rotation threat is pretty small but not zero.

CWG - I know you guys addressed flights in one of your earlier posts today, but in light of the new watch I was curious as to your thoughts.

Flying out of DCA around 8 tonight. You think we'll get off the ground on time? (I'm already assuming it's going to be a wild ride and I'll be white knuckling the arm rests.)

Posted by: AlexandriaAnnaTH | August 5, 2010 2:25 PM | Report abuse

@AlexandriaAnnaTH

Things should be quieting down weather-wise by around that time, so it may be more a matter of whether there's any residual effects from earlier potential delays.

Posted by: CapitalWeatherGang | August 5, 2010 2:39 PM | Report abuse

CuseFan - I was thinking the same thing. My wife thinks I am crazy for always talking about Octoberfest, but for me, it represents the transition to Fall, my favorite time of year. I admire Summer Ale fans though :) As long as you like Sam Adams, you can't go wrong in my book!

The gust front appears to be blasting thru Manassas, and spouse reports that in Centreville it started raining minutes ago and "even if it stopped right now you won't have to water tomorrow".
Guess that means a lot of rain.

Nice wind core heading toward Fairfax.

Once this line goes through will that be it or do we need to worry about the storms out in WV? I'm supposed to be driving up to Hagerstown after work and I'm trying to figure out if I'll get blasted either going or coming home later this evening.

Temp dropped from 91 to 71 in 10 minutes here in Fairfax.

Storms a brewin' here in Adams Morgan! A couple raindrops fell and everyone outdoors scattered. Dark as night out there and distant rumbles of thunder. Needless to say, I am giddy!

And yes, a Cuse Fan from MA...living in MD now! Both Fenway & the brewery tour are awesome :)

It looks like the bulk of the storms are staying on the south side of the state border. This bodes well for us Rockville folk huh?

Incredibly dark here in Dupont Circle, and thunder is rumbling. No rain so far but I'm sure it'll come within ten minutes.

First rumble of thunder heard in Rosslyn. Was going to walk up to CVS but I think I'll wait awhile. Looking to the north it's very dark. Still some light blue in the sky to the south.

CWG - hoping to catch some tennis at Legg Mason tonight. What's your forecast for this afternoon and evening? Is this the only line of t-storms? Weather.com (for what it's worth) is saying storms should end by 5.

Winds around Alexandria look very strong, radar looking somewhat similar to July 25 now in the core wind area.

Power is out at home in Del Ray. Flickering on-and-off at the office in Tysons.

I'd estimate we had some gusts around 45mph at Nationals Stadium.

About 10 minutes ago in Huntington I watched a gust of wind pull a tree apart like a wishbone. Wow.

First wave seems not to have caused much damage in downtown Silver Spring and Rock Creek Forest. Power still on @ 3:55 pm.

Posted by: Hendo1 | August 5, 2010 3:57 PM | Report abuse

Winds in Seminary Hill section of Alexandria were worse than July 25, based on the amount of tree damage, and the extent of tree lean. Power flickered, and went out for about 20 seconds, but surprisingly, is back on now.

It looked like Isabel out there. I would not be surprised if winds hit 70+.

Nice gust front in Suitland, 35 mph winds and about a 15 degree drop in seconds. I'm back in the Ops room now and still hearing some pretty sick thunder.

Hendo1, most of D.C. missed out on the worst winds, it traveled just south this time. The core SE of D.C. looks really wicked right now, serious winds probably heading towards Andrews etc.

And there goes the power. Luckily we have backup generators in our ops room. My car's stuck in the parking garage now until we get it back though.

well...there was sound and fury for a while here, but ultimately...nothing: no 1.5" hail, no wind damage i can see, and fortunately, no power outage for me anyway. looks to be on the way out.

so is that it for today? i do see another batch on doppler radar out in west virginia possibly headed our way.

Still have power in Huntington. Ride home was wild. Gust front hit while at the signal on St. Barnabas at the Beltway about 3:45. Rain hit before I even made the Inner Loop split. Then between driving rain, cloud-to-ground lightining hitting lightpoles all over the place, what I'd estimate as 50-55mph winds, and stupid drivers stopping under the overpasses WHILE STILL IN THE TRAVEL LANE, it took a good 10 minutes just to get down to the Wilson Bridge. Things improved after that.

looks like it's trying to get interesting here again. light rain, a bit of wind, and rolling thunder off in the distance.

i've got to say, something is off with the timing on the "d.c. area radar and lightning loop" radar. the time stamp on it says one minute ago, and it's showing a clear spot over me, but looking out the window, well, i'm seeing something....

Brian-
The view across the intersection of Silver Hill Road and Suitland Road was quite impressive. I couldn't even see the "tactical" Subway at the peak, and there were a number of lighting strikes within a quarter mile.

I thought this would be winding down out here in the PWC/western Fairfax area by now, but it looks as if there's more coming in so I'll be driving in it.
We've had heavy rains in Manassas, so I'll avoid Groveton Road; it often floods.

Western Fairfax being hit with round two. Heavy rain and thunder and lightning and it looks like a horizontal line of storms has formed stretching from western Fairfax County all the way to the West Virginia border. Let's hope these things don't train for hours from west to east. So much for the atmosphere stabilizing.
