That I66 line got lame in a hurry.  Down to 78 with the outflow here.  Practically pleasant.

Personal amateur thoughts (correct me where needed):

Yeah. That I-66 line was doomed once the southern storms quickly matured (close enough to the I-66 line to rob it of lift.) They would also have to deal with the high clouds blowing northwards from the southern storms blocking sunshine from reaching the surface stunting low-level mixing, again, making storm survival more difficult. The gust front from the southern storms sealed the deal.

I was thinking the same as George BM above - that it might crumble as the first line blew up and robbed the trailing line of energy.

Sometimes it seems to play a huge factor, and other times it doesn’t.  I’m sure it is all about the structure of the atmosphere above the surface.  My 0.01” suggests that it was a killer this time.

Okay.. so my dad who is 73 years old, lives in Rosedale and who's hobby is the weather.. just told my mom that that storm was the worst storm he ever saw in his life.  

I guess we dont have any representation from that side of Baltimore county here :)

there were posts on it in the disc/obs thread from a few over that way

From SPC-

Effective bulk shear of 30-35 kt with straight hodographs, MLCAPE of 1000-2000 J/kg, and steep low-level lapse rates will favor a mix of clusters and splitting cells capable of producing damaging gusts and isolated large hail until the storms shift offshore by this evening.

 

I'm down for that. My yard is probably due for a miss though.

Maybe a few isolated severe storms this afternoon?

   Definite competing factors today.     As noted above, the instability, deep layer shear, and low-level lapse rates are really good.    On the downside, low-level westerly flow here (which occurs when the surface low is well to our northeast) tends to dry out the lower levels and limit convergence along the cold front.      The threat is certainly better the further east and northeast one goes, but the overall trend in the CAMs for the local area is positive, especially with the HRRR seeming to come on board this morning.
