Yea this was okay.

Almost looks like serial bow echos (not using the D-word as it doesn't meet the criteria) - but with the Columbia bow and now the DC one. Cool radar signature.

[09-10 analogy]

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,

Was decent with winds when it hit. Maybe gusts to 40 IMBY. Nice storms

Wow, I wasn’t anything close to that up here. Maybe 45-50 tops.

[MDphotog]

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.

[WEATHER53]

BW parkway by blue plains had flying leaves and branches, no real limbs, would estimate 60mph 

[NorthArlington101]

[bigjohndc]

It looked ugly at the capital, but only a brief gust and rain. Nothing close to the 68mph to our south.

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.

[cheese007]

Man I came to DC from DFW thinking I would avoid all of this and I ended up under my first tor warning in ages

[09-10 analogy]

Outperformed for sure. Would love a round 2 even if it’s only GV.

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.

Sheesh.

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

[frd]

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.    

 

[Tater Tot]

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!

[frd]

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. 

[mattie g]

One large tree ripped out of the ground and another split in half down by the Tidal Pool. Lots of smaller branches down, too.

What are our chances at a round 2?

Probably nothing.  Not that there was even a round one up here.  Just a quick shower and one, yes one rumble of thunder!  Big NON event here and we were solidly in enhanced whereas y'all to our south got legit severe.

[NorthArlington101]

Sure it was nothing like Superstorm Sandy!

Dont come stirring pots in here. It’s one of the few remaining severe threads worth a damn.

Tons of damage here in Columbia. Took a ride back to my old neighborhood because I saw the worst of the velocities pass over and found trees into houses and many roads impassable due to several massive trees across the road. Trying to upload some pictures as I was let inside the house before it was officially condemned. This was by far the best storm in fairly recent memory - possibly since  the derecho.

Got a text from a friend leaving his office near Ellicott City.  He sent me a pic of the ramp at 32 and 100 with a tree blocking everything except the shoulder.  Looks bad.  Stay safe out there!  Lots of trees can still fall after the storm, been there done that!

[snjókoma]

Power’s out. Great storm. No trees down in the hood but a bunch of construction barriers at the nearby high school were blown over.

That is saying a lot. Remember that like it was yesterday. Sounded like a freightr train for a good 15 minutes , took down countless 50 to 200 feet Pines on the road in front of our development. Took many days to recover in regards to tree clean-up, and getting power to those who did not have underground electric hook-up. 

Interesting the enhanced area today,  to a degree today fizzled,  where as the slight risk become the real deal. Maybe the heating, and more sun, not sure.
