Nice little swirl over West Virginia. If we can get enough sunshine today, we might get some decent storms south of I-70. Might be a DC to EZF special.

HRRR actually has something coming through Central Maryland this afternoon.

Am more worried about heavy rain / flash flooding the next few days. Storms will be moving but PWAT's near 2" will dump no matter what. One of our stations (Hancock) got 1/2" in 10 minutes at 4AM this morning in a relatively benign shower.

Sligo Creek, I'm looking at you.

Someone (or a few people) in the next few days - will get microbursted I think. But probably not a region-wide event. 

    I agree that SVR potential today is limited by lousy shear, although MCVs can be sneaky   Lousy shear will also be an issue Friday, although high instability and organization of storms along the front might counteract that.   But Thursday might have the best combination of shear and instability and allow for a more widespread event, although the source of triggering is less obvious than on the other two days.

Quite a bit of initiation happening on the higher terrain to the west. 

Yeah, even though the timing/coverage differ, the fact that EVERY CAM has storms in the DC area later today was such a great sign this morning.  An MCV with favorable timing is usually a great combination.

Per the latest SPC mesonanalysis, there appears to be a bit of a lee trough running from CHO up to Harrisburg. 

Will that help with severe chances today or just help convection start? Seems we have Cape and not much else to work with today (bad shear, bad ML lapse rates, okay surface lapse rates). Either way how likely do you think it is we get some thunder today? I’m head coach for a swim team from 3:45 to 6:15pm so I gotta monitor the situation.

They can and often do act as a forcing mechanism. More lift!
