Yep I at .62” as of now. 

[BlizzardNole]

Man did my area get cut down.  Forecast went from 0.5 to 0.75 for today and tonight to just 0.25 to 0.5 for tonight after nothing today.  Oh well I guess the all day thick overcast killed it

Looking at that line die a little in the middle gives me Stephens City vibes

[nw baltimore wx]

A little over half an inch earlier and now some sun through breaks in the clouds.

[dailylurker]

Damn. Not looking that impressive. Just a wall of severe thunderstorm warnings for average looking scattered storms. 

 

Edit: Looking a little better 

[RDM]

Odd - hearing a regular bout of thunder rumble from the inbound system approaching NOVA.  But the Lightening app shows only a few hits out by Winchester and more to the SW.  Wonder if there isn't a bug in the app and/or some sensors that are down?   

[IronTy]

Doing caterpillar work, could it be any more gross outside?  Perfectly still, disgusting air.

Activity has picked up on that cell by Dulles.

Dud out here 

[Wintrest]

Resonant thunder heard from miles out. I hope this first line just dumps.

[Weather Will]

Heavy rain moving back in!

[SnowenOutThere]

2-3 inches of rain per hour rates right now with over .7 in the gauge. 

[WxUSAF]

Damn going to be a pretty awful bust for MBY. Euro was steady with 1.5”+ today for many runs. 

[Mrs.J]

Well my area went back to look at that storm coming in, oh wait it is Ballenger Creek que up the split and then reform just to the East.

That cell just south or south southwest of Urbana could be on the way, close call.

[jewell2188]

What a joke lol

[Weather Will]

About .75 for the day.  

[CAPE]

Yet another turd here lol

S MD and down towards Richmond looking pretty good. 

[IronTy]

Well this event sucked.  Was it even supposed to rain today?

[CAPE]

Impressive how often there has been heavy rain wording in the AFDs with inch+ amounts in the forecast that literally yield nothing. All summer long. They must be just using AI or guessing because the globals are awful with resolving convection(not their forte) and all the mesos suck and are always all over the place. Today is a classic example. Need better hi-res models I guess. When they all depict different outcomes run to run something isn't working right. Too many forecast busts tell the story.

Ended with 1.37 inches of rain throughout today. Watching an epic light show to the southeast of me from my deck. One of the best I’ve seen in years.

Lucked out here with this one  .84"   Most we've had in this immediate area for a while...
