Southwestern Carroll County in north central Maryland... Northwestern Howard County in central Maryland... Central Montgomery County in central Maryland... Southeastern Frederick County in north central Maryland... Central Loudoun County in northern Virginia... Northern Fairfax County in northern Virginia... * Until 245 PM EDT. * At 213 PM EDT, severe thunderstorms were located along a line extending from near Linganore-Bartonsville to near Point Of Rocks to 6 miles north of Poolesville to near Leesburg to Purcellville, moving east at 25 mph. HAZARD...60 mph wind gusts and quarter size hail. SOURCE...Radar indicated. IMPACT...Damaging winds will cause some trees and large branches to fall. This could injure those outdoors, as well as damage homes and vehicles. Roadways may become blocked by downed trees. Localized power outages are possible. Unsecured light objects may become projectiles. * Locations impacted include... Germantown, Rockville, Gaithersburg, Leesburg, Olney, Damascus, Lansdowne, Lowes Island, Poolesville, Ashburn, Montgomery Village, North Potomac, Redland, Countryside, Purcellville, Round Hill, Boyds, Green Valley, Clarksburg, and Darnestown. PRECAUTIONARY/PREPAREDNESS ACTIONS... For your protection move to an interior room on the lowest floor of a building. Large hail, damaging wind, and continuous cloud to ground lightning are occurring with these storms. Move indoors immediately. Lightning is one of nature`s leading killers. Remember, if you can hear thunder, you are close enough to be struck by lightning. Torrential rainfall is occurring with these storms, and may lead to flash flooding. Do not drive your vehicle through flooded roadways. Link to comment Share on other sites More sharing options...

SnowenOutThere Posted Thursday at 06:30 PM Share Posted Thursday at 06:30 PM That MD cell has some storm rotation. Not tight or anything but I’m sure someone will get a nice storm picture of a sculpted base or something. 1 Link to comment Share on other sites More sharing options...

As details on this system become more defined, will have to continue to monitor synoptic fluctuations in model guidance to help identify any hazards associated with this system in the coming days.

high risk Posted 1 hour ago Share Posted 1 hour ago The rare Day 7 SPC outlook for our area! 1 Link to comment Share on other sites More sharing options...
frd Posted 1 hour ago Share Posted 1 hour ago https://www.spc.noaa.gov/products/exper/day4-8/ ... Friday/Day 7 and Beyond -- Upper Great Lakes into the Mid-Atlantic ... Strong northwest flow will be established between the previously described western US ridge and eastern Canadian trough. Rich boundary layer moisture is expected to be present to the south of a residual cold front that will be draped somewhere from the Great Lakes southeast into the Mid-Atlantic/Southern New England. Strong diurnal heating each afternoon will support scattered thunderstorm development capable of producing damaging outflows. Severe probabilities were introduced for Day 7 with this outlook given increasing confidence in thunderstorms developing within surface troughing east of the Appalachians. The exact location of these highlights will likely be refined with subsequent outlooks. Additionally, the overall large-scale pattern seems conducive for one or more shortwave troughs to move through the broader northwesterly flow across this region. Given the (seasonably) strongly unstable and sheared environment, one or more southeastward moving MCSs may be possible during the Day 7 - Day 10 period. Ensemble guidance varies significantly as to the timing and location of these potential short-wave troughs, but the overall pattern would suggest additional severe weather potential at the end of the forecast period and in the days that follow. ..Marsh.. 07/11/2026 Link to comment Share on other sites More sharing options...
