That I-81 corridor is cooking pretty good.  Hagerstown and Harpers Ferry into the low 80s.  York and Gettysburg are now well into the upper 70s too.  That seems like the zone.  Wouldn't shock me if SPC pulls the ENH back west of the cities with the afternoon update.

Mesoscale Discussion 0623
   NWS Storm Prediction Center Norman OK
   1241 PM CDT Mon May 01 2017

   Areas affected...western New York through central Pennsylvania

   Concerning...Severe potential...Tornado Watch likely 

   Valid 011741Z - 011845Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Severe storm threat with damaging wind and a few tornadoes
   should continue to expand eastward into western NY and central PA
   this afternoon. A tornado watch will likely be issued soon.

   DISCUSSION...Organized line of storms with embedded mesovortices and
   bowing segments from Lake Erie through extreme eastern OH is moving
   east at around 40 kt. VWP data and special Pittsburg RAOB show very
   favorable wind profiles for embedded supercells with large 0-1 km
   hodographs. Latest visible imagery also show numerous cloud breaks
   which will promote further destabilization of the boundary layer
   with 500-1000 J/kg MLCAPE this afternoon.

We'll be surrounded by tornado watches at this rate :lol:

Clouds coming back in it seems. Not sure we got enough sun - guess we'll see. I hope we can stop with these puny events soon and get some fun severe.

And when we do get one I can see it now - 

WATCH UNLIKELY

Storms could produce isolated severe wind gusts but the overall threat is waning due to loss of heating. Watch not anticipated at this time but trends will be monitored.
