Thunder potential Sunday PM-Monday

Recommended Posts

we had a heavy T'storm move through here in Kennebunkport between 10:15 and 10:45. I saw 2 lightning strikes in the woods behind the house

and 3/4 inch hail. A pretty impressive storm considering it's been cloudy and drizzling all morning with a Temp of 47*.

Yeah, our best storms are usually on the cool side of the wf this time of year rather than being in the "warm sector" and getting a cf passage.

Case in point:

CURRENT INDICATIONS

ARE THAT SCATTERED THUNDERSTORMS WILL DEVELOP BY MID AFTERNOON OVER

PORTIONS OF NY/PA INTO THE CENTRAL APPALACHIANS AND SPREAD QUICKLY

EASTWARD. ONSHORE FLOW AND ASSOCIATED MORE STABLE AIR MASS WILL

LIMIT EASTWARD PROGRESSION OF STORMS TO THE COAST.

There's actually an elevated mixed layer across portions of the northeast. Check out the sounding from IAD and those mid level lapse rates!!

ALY's 12z sounding had a bit of an EML with steep mid level lapse rates as well. Those helped us generate a lot of MUCAPE above the stable boundary layer to fuel those nasty storms in N NY and N New England this morning.

Yeah I saw that. Albany had an impressive sounding.

For sure. IAD had a 500-700mb lapse rate of 8.8 c/km!

Places that can generate surface based CAPE today are going to have some fun. Possible tornado threat too around Albany if boundary layer winds stay backed.

Very interesting to see the focus shift yesterday to today from the severe weather over the Midwest continuing into the Northeast, to the Southeast. Definitely indicative of the trough fracture, and the central Plains disturbance becoming dominant
