2:35pm: Storms continue to weaken as they enter Montgomery County and move into Leesburg as well in Loudoun County. There is still some gusty winds and heavy rain associated. I have seen winds in the mid 30s and rainfall totals up to a quarter of an inch with this line. The southern extent of the line has drastically weakened.
2:13pm: This line of heavy rain and gusty winds will move into the City of Frederick in the next 5 minutes as well as Leesburg, VA in the next 15 minutes. This line still doesn't have any severe characteristics.
2:02pm: Thank you everyone for your reports of heavy rain entering the western suburbs with this line. It will move into Frederick and Loudoun Counties now and towards the D.C. Metro closer to 3pm if it holds together. The highest wind gusts were 41mph in Brunswick in Frederick County, MD and 40mph in Woodstock along I-81 in Shenandoah County, VA.

1:33pm: A Mesoscale Discussion was put out for the majority of our area around Noon highlighting the fact that the severe threat would decrease through the afternoon hours. With that being said, this lone of storms is continuing to move through the Shenandoah Valley with some of the stronger parts of the line moving through Washington Co., MD and Berkeley County in WV. Shepherdstown and Myersville down the line should prepare to seek shelter indoors as this line moves into those areas in the next 10 (Shepherdstown) to 30 (Myersville) min.
1:25pm: Here is video of the tornado that went through parts of northern Georgia earlier today. Video Here
1:17pm: The current line of storms west of the D.C. area will move into Hagerstown, Martinsburg and Winchester all along the I-81 corridor in the next 10-15 minutes. Wind gusts to 50mph are possible along with very heavy rainfall, though there are no warnings in place at this time.
TIMING: We think this first line that is currently moving into the Shenandoah Valley will weaken as it crosses the Blue Ridge. The main timing for the stronger, heavier rain and storms will be closer to Midnight, with the timing even sooner, 10-11pm in the western and far western suburbs. Here is a good look at a trustworthy model showing a line of storms pushing through the D.C. area right after Midnight.

12:49pm: Check out our Live Super Doppler Radar. The line of heavy rain that is currently on it is a low-topped line which should move closer to the Blue Ridge Mountains around 2pm. We currently don't think this line will hold together as it moves east of the Blue Ridge into a more stable atmosphere. That line has already showed signs of weakening as it has been exiting West Virginia.
12:39pm: Here is a look at the current outlooks as far as the risk for severe weather from the Storm Predicition Center. Just about the entire east coast has a chance for severe weather, with the primary threat coming in the form of damaging winds.
- Current Outlook from the Storm Prediction Center
12:30pm: Winds are already gusting from the 20 to 30 mph range right now out of the south out ahead of the cold front. Even some of the sustained winds are at or just above 30 mph. This gives a good idea of just how strong this front is.
12:14pm: A Flash Flood Watch is in effect for parts of the D.C. area including the D.C. Metro from 3pm through late tonight. It is a Flash Flood Watch and not a Flood Watch in our area as very heavy rainfall may fall in a very short period of time, leading to Flash Flooding.
