TORNADO WARNING FOR THE MALL

 

I had a great view of that as it passed south of my office.  There was definitely some lowering and broad rotation.  Skies were about as green as I've seen them as the line was rolling in.

Alright so THAT was a good line and some good thunderstorms. I always joke that the "severe thunderstorms" we get up here are basically what we get every day in Louisiana.

 

This one though, this one was legit.

...A SEVERE THUNDERSTORM WARNING REMAINS IN EFFECT UNTIL 415 PM EDT
FOR THE DISTRICT OF COLUMBIA...SOUTH CENTRAL ANNE ARUNDEL...SOUTH
CENTRAL MONTGOMERY...NORTHWESTERN CALVERT...PRINCE GEORGES...NORTHERN
CHARLES...ARLINGTON...EASTERN FAIRFAX...AND SOUTHEASTERN PRINCE
WILLIAM COUNTIES...THE CITY OF FALLS CHURCH AND THE CITY OF
ALEXANDRIA...

At 350 PM EDT, severe thunderstorms were located along a line
extending from College Park to Alexandria to near Montclair, moving
east at 45 mph.

These are very dangerous storms.

HAZARD...80 mph wind gusts and quarter size hail.

SOURCE...Automated weather station. Reagan National Airport recorded
         a wind gust to 68 mph.

IMPACT...Expect considerable damage to trees and power lines. Your
         life is at significant risk if outdoors. In addition to
         some trees falling into homes, wind damage is possible to
         roofs, sheds, open garages, and mobile homes.

Locations impacted include...
Arlington, Alexandria, Waldorf, Dale City, Bethesda, Bowie,
Annandale, Clinton, Springfield, College Park, Fort Washington,
Langley Park, Fort Hunt, Groveton, Forestville, Falls Church,
Huntington, Largo, Coral Hills and Bladensburg.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Remain alert for a possible tornado! Tornadoes can develop quickly
from severe thunderstorms. If you spot a tornado go at once into the
basement or small central room in a sturdy structure.

This is an EXTREMELY DANGEROUS SITUATION with tornado like wind
speeds expected. Mobile homes and high profile vehicles are
especially susceptible to winds of this magnitude and may be
overturned. For your protection move to an interior room on the
lowest floor of a building. These storms have the potential to cause
serious injury and significant property damage.

This is going to stabilize us pretty good. HRRR says nothing after. Which is fine by me - this was a GREAT event for our area. 

Yea this was okay.

Great looking storm though nothing really noteworthy in upper NW. Some good wind and the obligatory 3-min cloudburst. As often the case some good stokes and booms even as the western sky is clearing.I thought I might have heard some hail as I was driving back from my vantage but it was pollen-size if it was and thus pretty much indistinguishable from raindrops. But the storm did have a great look— best I’ve seen in a while, I know that’s totally subjective but I,ve always been into weather for the aesthetics and the theater of it: great shelf cloud, a lot of green tint (maybe that’s why I had an audio-llucination of “hail”), some profound CG off to the distance. Looked particularly nasty as I looked due north from Ft Reno; no surprise as central MOCO seemed to have this one’s beam on it,

It just passed thru Glen Burnie on the north end and it was pretty garden variety here.  Some wind but nothing too serious and some heavy rain.  Got some lightning but again nothing more than they typical summer storms.  Sounds like the real stuff was to the south.

This is reminiscent of the "classic" solid lines of storms that some of us have discussed as being less common than in the 90s and earlier 2000s. 

I always just thought I was crazy for thinking this. It’s so rare that we get these classic, quick squall lines anymore, yet I remember them being a sort of regular occurrence when I was a kid.

AA county holding dismissal due to tornado warnings.

 

Fun little storm, but mostly wind.  Only .25" as it was a fast mover

Same here, I swear in Columbia in the 90s we would get those lines all the time and hail was a lot more frequent as well.  Up until last year I think it had been 8 or 9 years since I had seen a good hail storm at home.  I guess some of those little quirks of climate change.

8 hours ago, high risk said:

The CAM solutions are a bit mixed, mostly based on how they evolve the ongoing OH storms.    The "good" CAM solutions have storms forming on the outflow of that system (or least some sort of remnant boundary) and rolling through here during the 3-5pm timeframe or so.   Mappy correctly notes that getting some good heating would help a ton, and most guidance makes that happen.      The shear definitely supports some supercells in addition to line segments, although I think it's more of a hail/wind day than a tornado day.

            This post aged fairly well.     :P

Sheesh.
 

You normally see that kind of damage with a tornado, right?

For Northern Delaware the incoming line dissapated, maybe a trace of rain at my location.  What a dissapointment. 

Looks like Philly got hit and you guys from Baltimore SW got it good. So then continues the now growing dry spell for the majority of the Northern 1/3 of the Delmarva.

Really impressive downpour here. Wind was nothing special, although it still knocked the power out for a few minutes lmao. Sun is already peeking back out. It was cute!

Props to @high risk Good job !

He said the line would intensify for some areas and it did so.

Some pretty impressive wind gusts and damage reports comming in now for areas far to my SW.
