Severe Thunderstorm Watch coming out. A smaller Tornado Watch may be right on it's heels.

I would be surprised if the bay bounties didn't get a TOR watch.

If you want some real giggles, head on over to the SPC meso analysis and see where the Violent Tornado Parameter (located under Composite Indices) is bullseyed.

Surprised no tor watch. 5% typically means one here. And w/ the CIG1 hatched area?

Georgteown storm appears supercellular.

EDIT: Now a TOR issued.

That sure looks like a supercell for Loudoun

That kind of SCP/SIGTOR bulls-eye is excellent for this time of year Mid-Atlantic or NEUS.

And despite all the clouds and earlier showers, sfc-based CAPE is high w/ the bulls-eye just SE of the metro and a good gradient N suburbs.  Current svr storm to the W ride that gradient (boundary)!

Did give the Tornado Possible in the warning. Good looking hook at times.

I don't think I have ever seen a TOR watch "nested" inside a larger SVR watch.  Has that ever occurred before?

Got clipped in Frederick by what can only be described as a tropical level downpour. It completely matches the humidity level preceding it.

That cluster looks like garbage. Just a bunch of crapvection. Tornado risk is the best east of here into S New Jersey, IMO.

Absolutely felt tropical. A few rumbles of thunder but just poured for 30 min straight

[yoda]

40/20 tor probs... pretty decent for our area.  50/30 wind

I can see the Owings Mills split already coming 

[SomeguyfromTakomaPark]

I'm not seeing much signs of life on the radar for DC, is it supposed to fire up later?

Fwiw, SPC disco from the tornado watch makes it seem we see storms this evening 

SUMMARY...Scattered severe thunderstorms are forecast to continue to
   develop and intensify through the afternoon and into the evening.  A
   few of the stronger storms will be supercells capable of a risk for
   tornadoes, damaging gusts, and large hail.  A consolidation of
   storms will probably occur during the evening as one or two line
   segments develops with an attendant risk for damaging winds and
   possibly a tornado.

[Kleimax]

Storm east of Thurmont could get interesting
