2022 Mid-Atlantic Severe Wx Thread (General Discussion Etc)

[Kmlwx]

TDWRs are showing echo tops already nearing 50kft now with that cell. 

[Hank Scorpio]

Towers going up looking towards southern Loudoun / northern PW county. Guessing we see radar light up down that way shortly

[batmanbrad]

cell near Potomac/Rockville has 1.5" hail tag per RadarScope

[Kmlwx]

PWS lightning detector keeps going up, up, up. 62 69 strikes associated with this storm already - and it's definitely missed some I'm sure. 

[Kmlwx]

TDCA showing 52kft tops now. Nearly continuous rumbles of thunder being heard here now. The little "arms" of the storm are into Glenmont now. Should be raining here momentarily. We'll see if it maintains or starts to collapse. Decent amount of juice to work with based on the earlier SPC meso maps.

Is that a potential downburst signature on that cell now? Looks like all the TDWRs and the LWX radar are seeing winds moving away from each other. 

Yes.

[MN Transplant]

Lightning indicators showing up well away from the MoCo cell.  Good idea to be inside.

[batmanbrad]

I'm up here near Laytonsville and I can hear rumbles of thunder - distant/faint, but I hear them nonetheless.  Don't see anything close on radar, can those actually be from that cell downcounty?  Seems like a rather large distance between it and me.

Doing a rough summation of the lightning indicators from AllisonHouse yields really high numbers. This weekend in particular...likely to be tons of people outdoors. Hope they are heeding the warnings.

Yes. THere are strikes being shown between Montgomery Village and Brookeville.

Two CG strikes a little bit east of Falls Church just in past few minutes 

[Kmlwx]

VIL numbers are weakening from the LWX radar on this storm. 

[Kmlwx]

TDCA still has a good hail indicator on it, though. CIMMS probsevere product has 57% for wind and 20% for hail. 

[Kmlwx]

MCFRS PIO is tweeting several storm reports of trees down in the Potomac area. 

[yoda]

That's a sharp NE turn on the newest STW from LWX on the Montgomery County storm

[09-10 analogy]

Yeah, really nice V-shaped notch on that MOCO cell. Constant low rumbling thunder in upper NW, this one will miss to my north, but I opened the window because I love that sound. Nature's version of Jason Newsted. Well, maybe not *that* loud.

Seems there are two "cores" or local maxes in reflectivity. One is down W of Kensington area and the other is that new warning. The new warning is the dominant one it seems. 

[Kmlwx]

The original warning was updated as well to indicate the trees down reports from Potomac, MD (pretty close to my office, actually!). 

[Kmlwx]

Some new strikes being shown near Potomac on the ENTLN data coinciding with some weak but new reflectivity returns in that area. Maybe some back building? These storms are relatively slow movers too...definite risk of urban or small stream/creek flooding.

Really blew up just east of Potomac in past 10 minutes

Doesn't look like it'll cycle up like the original storm did. Radar looking messy now as more little cells start to pop up elsewhere (W of Leesburg, Laytonsville, Sykesville, N of Ellicott City.

Everything had missed or died out and I couldn’t be happier. 

[mappy]

I’m also fairly intoxicated, happy 4th friends!

DRUNK: Reported
HANGOVER: Possible

[nw baltimore wx]

Sitting on the porch and lots of CG lightning just southeast. Good rains and nice breeze here.

[09-10 analogy]

Clouds getting a bit of ye old mammatus look to my NW. 

[batmanbrad]

fairly heavy rain and occasional lightning/thunder here in Gaithersburg (east side, just west of Laytonsville).  Definitely looks like some of this recent development here in mid county could be due to interactions with some of those outflow boundaries that dropped south from the earlier storms near Frederick/I-70.

[AmericanWxFreak]

Crazy crazy CG in Columbia. WOW. 

[nw baltimore wx]

Damn. Probably should be inside. Check out this feeler trying to get to us on the porch.

[WEATHER53]

Intense in Baltimore by the stadiums
