Hooking down by Potomac MD... but that's due to new development I believe

Yep - new little cell. Not seeing much lightning on it. We are probably transferring to more of a heavy rain threat with any new activity. Beefy stuff up by Baltimore could still trigger a warning or two.

Looks like I’ll come home from vacation to a brown lawn and dead plants. Happy July!

Nah, sunny in Maui and nothing measurable at the PWSs near home

[Hank Scorpio]

At least this storm looked nice as it missed me just to the north 

[Kmlwx]

Somewhere in the area between Wolf Trap to NW DC up in the MoCo Belway area to College Park is probably going to see a Flood Warning (or FFW) at some point. Lots of heavy rain sticking around.

[mappy]

Little rain coming through now, hope it stops in time for Big Truck to set off fireworks

Outstanding photograph

Why are the airport radars throwing up TVS and rotation sigs but not LWX?

TDCA and TBWI are on Radarscope 

ETA: they aren't now... but we're earlier for a good time period 

[aldie 22]

So far I got nothin 

[MN Transplant]

Would be nice if some of this built south.  0.09”

Worst gif ever, but the base was showing the tiniest little itty bitty signs of rotation just as this cell got going. Guessing lots of storms do this though, and it's only through the power of a sped up gif I noticed anything

[09-10 analogy]

This is the definitive garden-variety thunderstorm. But I'm drinking because my wife and daughter are out of town, and I'm blasting Tom Waits and relieving the glories of bachelorhood. So it's OK.

ETA: Although that was a pretty impressive strike just now. Rattled the windows I think. 

[yoda]

Watch out by McLean... storm strengthening

Surprised we don’t have a FFW for northern DC/Silver Spring

[Scraff]

Reporting the Elkridge / Columbia line as “safe”.  5 drops of rain. Maybe 6.

enforcement and request they pass this information to the National
Weather Service when you can do so safely.

[09-10 analogy]

It's raining hard, but I've certainly seen heavier. Then again, "heavier" in my head canon is June 2006.

[MN Transplant]

No rain at IAD or DCA while miles away are getting pounded.  Mid-Atlantic summer in action.

[Eskimo Joe]

SVR w/ TOR possible tag coming for Cecil.

[biodhokie]

Non-stop fire sirens in Silver Spring. Makes me wonder if multiple water rescues are needed since people weren't turning around when I saw flooded roads.

[Kmlwx]

0z HRRR keeps activity forming overnight - appears non-severe of course, but some areas could still be in the game for some quick downpours even as late as 10z.
