Only the HRRR has anything decent for today and it's mostly south of DC. Would argue we all temper our expectations greatly.

Very messy radar now in WV. It's too early for this unfortunately if clouds or the activity itself moves into our area. Will be interested to see the 12z runs. 

[Kmlwx]

One encouraging sign is that my dewpoint has risen to the upper 60s (even pushing 70 at times). So the moisture has certainly advected back in. Some of the models that really didn't develop much instability seemed to have a dry pool of air in the area and especially in the eastern half of the area on earlier runs. However, I see dews are almost entirely into the mid to upper 60s across the area now...even low 70s in southern Maryland.

       While I agree that we should keep expectations in check, I'm sure if I totally agree with the details of this take.    The NAM Nest has certainly hated today for most of us in multiple runs, but last night's HiResWs ARW2 and FV3 were fine.   And while the HRRR doesn't like the tier of counties along the PA border, several runs have been plenty active for Montgomery/Howard/Baltimore.      Shear is fine today;  the question will how much of a westerly component is in the 850 flow and whether the early morning convection messes things up - both are certainly plausible fail scenarios.

[Kmlwx]

Hopefully that WV activity can stay out there for the morning at the very least. I saw a few runs yesterday that brought activity in as early as 17z in spots. If we can prevent crapvection from forming closer in to the major metro - we might be okay.

Sunny in the AM for a change on a day w/ potential storms at the moment in downtown Baltimore.

40 minutes later...never mind.

12z HRRR seems like it missed/is missing all of the crapvection in WV...but it delivers a healthy line into the area this afternoon.

13z HRRR is nice too, but it seems to be on an island.

12z RAP brings a nice line through as well.

Actually so is the 12z FV3, ARW, ARW2 AND the HERDERPS.

Take a look at the visible loop. Looks like a little swirl or vort max near Pittsburgh diving SE. Might be what's going to trigger our line this afternoon.

Let’s just keep that cell rolling down 66

Certainly seems like all this messy convection about to come off the high terrain will be here very early. There's a lot of it too...not just a few cells. If that doesn't intensify it'll probably dampen our instability big time.

I have a feeling it's going to consolidate and intensify just as it hits Rt 15, and that will be the event for the day.

I bet that stuff in Ohio and central WV sinking SE steals all of the love for later and this first batch is it. Seen this movie before

2% tor introduced on 1630z OTLK 

[AmericanWxFreak]

So we thinking this initial activity blows through and we get a the main round a couple hours later?

D3 SLGT too

[Kmlwx]

I'm starting to think either we are cooked for severe today or this stuff gets out of the way and something forms/comes through late afternoon/early evening. 

[Kmlwx]

Latest HRRR sucks. 

[weatherCCB]

Looks like this first batch should be outta here by 2 pm.

light rain here now

First batch is optimistic... I like it.

Just had a decent storm roll through just North of FXBG. Over 1.5” inches of rain wind gust to 42mph, it’s now warned East of here.

[Eskimo Joe]

TOR possible now on the King George, VA cell.

Your area sure has cashed in a lot within the past year or so.

The fat lady is warming up for those of us not being impacted by the King George, VA cluster. HRRR continues to suck for this afternoon.

Sun is back out in Rockville. 79/75 on my PWS

I swear the dog-leg turn in the Potomac causes things to spin up down there more than normal. Anyone know if this has ever been looked into?

[mappy]

misty rain in Hunt Valley, nada at home. Everything went south.
