Tomorrow looks ok to me.

 

...PA/NY/NEW ENGLAND...
AN UPPER-LEVEL TROUGH WILL MOVE EWD ACROSS THE LOWER GREAT LAKES
REGION ON THURSDAY. AT THE SFC...A COLD FRONT SHOULD ADVANCE SEWD
INTO THE CNTRL AND NRN APPALACHIAN MTNS. THUNDERSTORMS APPEAR LIKELY
TO BE ONGOING ALONG THE FRONT THURSDAY MORNING AND A GENERAL
INCREASE IN CONVECTIVE COVERAGE SHOULD OCCUR DURING THE DAY AS
INSTABILITY INCREASES AHEAD OF THE FRONT. SFC DEWPOINTS IN THE MID
TO UPPER 60S F ACROSS MUCH OF THE NERN STATES SHOULD ALLOW MODERATE
INSTABILITY TO DEVELOP ACROSS A BROAD AREA. THIS COMBINED WITH
WELL-FOCUSED LARGE-SCALE ASCENT AHEAD OF THE UPPER-LEVEL TROUGH
SHOULD ENABLE A SQUALL-LINE OR MULTI-SEGMENTED ORGANIZED LINE OF
STORMS TO MOVE ACROSS THE SLIGHT RISK AREA THURSDAY AFTERNOON.

FORECAST SOUNDINGS AT 21Z THU FROM MAINE SWWD INTO SERN NY SHOW
MLCAPE IN THE 2000 TO 2500 J/KG RANGE WITH 35 TO 40 KT OF 0-6 KM
SHEAR. THIS SHOULD BE ENOUGH TO SUPPORT SUPERCELL DEVELOPMENT MAINLY
WITH DISCRETE CELLS THAT INITIATE AHEAD OF THE DEVELOPING LINE TO
THE WEST. AN ISOLATED TORNADO AND LARGE HAIL THREAT WILL BE POSSIBLE
WITH SUPERCELLS. THE GREATER THREAT COULD BE FOR WIND DAMAGE WITH
THE POTENTIAL MAXIMIZED WHERE INSTABILITY AND LAPSE RATES BECOME
MOST FAVORABLE.

Capes look to push 5000 today. Haven't seen that in a while. A few showers with a few strikes already in WV/OH. Probably a bunch of pulse storms later today. 

It has come close a few times this summer and always the day before a cold front arrives so we end up lacking a "trigger" to really set things off... aka screwed as usual

 

then tomorrow we will prob get clouds or cloud debris early and values will not end up as high as today...

a nice looking slow moving cell in southeast Perry/northeast Cumberland right now... watch this slowly move over the city of Harrisburg but completely miss KMDT... home for me is 12 miles as the crow flies from KMDT and I am sitting on 6.11" since August 1st while airport has reported 3.12
