Trace so far.  Hoping for that cell back west of IAD, but that one holding together is asking a lot.

Just got SVR warned

Mesoscale Discussion 0952
   NWS Storm Prediction Center Norman OK
   0457 PM CDT Sun Jun 02 2019

   Areas affected...Eastern Virginia into the Delmarva Peninsula

   Concerning...Severe potential...Watch possible 

   Valid 022157Z - 022330Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Numerous storms in central Maryland and north central
   Virginia have produced severe hail for the past couple of hours. A
   new severe thunderstorm watch may be needed downstream of watch 315
   and 318.

   DISCUSSION...A combination of multicell and occasional right and
   left moving supercell thunderstorms have developed in north central
   Virginia and central Maryland over the past few hours. The
   environment ahead of these storms is characterized by around 1500
   J/kg of MLCAPE and mid-level lapse rates around 7 C/km per RAP
   mesoanalysis. In addition, the LWX VWP shows around 30 knots of
   mostly unidirectional deep layer shear. This parameter space will
   continue to support both left and right moving storms with a primary
   threat of large hail with some damaging winds possible as well. 

   A combination of ongoing convection drifting east-southeast out of
   the current watch area and new development on the southern flank of
   these storms may necessitate a new severe thunderstorm watch south
   and east of watch 315 and 318. The southern extent of the threat is
   uncertain. Primarily unidirectional westerly flow would suggest
   storm propagation mostly to the east, but guidance suggests
   thunderstorms will continue to develop southward with the cold
   front. However, by the time any storms arrive in far southern
   Virginia, the boundary layer may start to stabilize and limit the
   intensity of these storms.

Bwahaha now that's Damascus for you!

Whoa, lots of hail just started in Germantown

[smokeybandit]

Hail in odenton . Only fish egg sized though 

[Scraff]

Holy hell! Whatever just blew threw Elkridge was fun!  No thunder or lightning which is weird, but damn it ripped hard for a bit. Loved it!

Are you there?  What part?  I am 2 mile NE Germantown in the Milestone area, and have whiffed on everything again.  Saw purple on radar 2-3 miles north from one cell, then 2 miles south with this one.  Got nothing more than a brief shower.

I'm curious to know what those storms were like in Germantown and Gaithersburg - they looked wild on radar.

I live near the Chipotle in the town center. Pretty cool, pea sized hail

[BlizzardNole]

Nice video ge0 - thanks for posting!  Hard to believe that's so close -- I am just N of the intersection of 355 and Rt 27 and got 0.15 of rain and nothing else.  Clarksburg just as close to my north got a strong storm too.  This spot and Stephens City are uncanny.

[jacindc]

I had hail the size of whatever is one step up from pea sized on Capitol Hill. Jawbreaker size, I guess.

[AmericanWxFreak]

Fair amount of tree damage in Columbia again. I can't remember a stretch of severe like this in a VERY long time.

Lost two ~3” limbs off my sycamore plus lots of smaller branches. Strongest winds from any storm this year.

Yeah I was just getting some very distant rumbles and then the sky opened up and the wind got going. Pretty good storm with no T&L.

[nj2va]

Drove through the storm that hit the American Legion bridge/Beltway around 5p or so...lots of quarter sized hail.  Had to pull over on the shoulder on the Beltway with my hazards on since it was nearly impossible to see at one point.

Probably 545 I would guess reading the storm reports from Aspen Hill and Glen Echo

[Herb@MAWS]

Best storm in years IMBY in terms of wind + rain.  Started with a bit of T&L but then just pouring sheets of rain for a solid 30 minutes and quite windy for a solid 10-15 mins (it felt longer).  Tropical storm-like during the 10-15 mins of strong winds.  About 3/4"-1" rain.  Temp dropped from 84 to 71 during storm.

[yoda]

Huh... never seen STW issued by Fairbanks AK WFO before... they have issued 3 tonight

5 people were injured in Prince William county

Pretty tame in Columbia - but today was a BIG hail day for a good chunk of the area. Wow...severe season has been generous to this region this year. 

Let's see what we can do Wednesday.

.02” of rain as all storms missed me yesterday. 

[smokeybandit]

0.44". Fun storm, but short lived.

Yup. Missed as well, but, gotta say, was thrilled to miss rain and wind. Still needing things to dry out a bit in my part of the area from the last year's onslaught of moisture.
