Torrential downpour

It is funny how much the HHHR can swing in just an hour

Classic wet microburst signature on the Loudoun County cell.

Radarscope showing some increase in hail size, POSH's up to 40-50% on some of those cells out west including the one you mention.

.41 and counting the wind was a bit nuts at first so probably a bit more than that

If I recall correctly, the HRRR initializes off radar? Can @Ellinwood, @wxmeddler, @MillvilleWx, @wxmvpete or someone else confirm?

[87storms]

Whiteout rain with some hail mixed in.

[SnowenOutThere]

Areas along the Fredrick cells might need a flash flood warning with the training motion if they don’t collapse on themselves. 

[aldie 22]

Another round incoming thunder pretty impressive 

[batmanbrad]

current radar trends are supporting the earlier thinking that most of the major activity will be north of DC...

[aldie 22]

Im sitting on the porch and a lightning strike right in front of me yikes...pouring again 

[AnEndlessMaze]

I finally got that rain magnet fully calibrated. Enjoy! @EastCoast NPZ

.68 so far

[Hank Scorpio]

That lead cell in Loudoun missed me by just a few short miles. Interestingly even with no rain, just the outflow was able to drop the temp from 94° to 85°.

My kid is supposed to have a flag football game at 6 this evening. Guessing that isn't gonna happen. 

[Mrs.J]

Picked up .32” in a clear slot now. But all the thunder is so nice to hear. 

[Wxtrix]

made it almost all the way home from Winchester and now there’s a deluge outside—the roads are rivers. there was some debris on the road in Berryville so it must have gusted there decently.

[WEATHER53]

60 mph gusts in Frederick with 70mph peak possible.  Torrential rain 2-3” ph rate 

[kgottwald]

Looks like that stuff due W or NW of Warrenton will hit Merrifield in maybe an hour.

Wrong tense.

Patiently waiting here in Alexandria

[Weather Will]

HRRR is well underdone.....  lots of rain in Frederick area. I did not post earlier but the WB RRFS from 12Z did very well for this afternoon.  Will start using it.

[SnowenOutThere]

Southern severe cell is aimed directly at my backyard. Time to see if it falls apart or microbursts overhead. 

[Weather Will]

WB 18Z RRFS thru early am Friday.

[MN Transplant]

Need to build that line south to get some breathing room.

[scope1]

Gust front blowing through here right now. Windy. 

[Kmlwx]

Wind signature near The Plains. 

[SnowenOutThere]

I need that cell out near the plains to hold together and not drift north. Still hasn't shown a microburst signature of collapse yet, but the gust front is far out ahead of it so I doubt it can keep going forever.

Random TW from RLX near Charleston, WV

[Eskimo Joe]

Several LSRs out of Frederick County, MD. Looks like they were the "winners" today.

[WxUSAF]

Commute home looks entertaining
