AREAS AFFECTED...PA/MD/NJ/DE/SRN NY

CONCERNING...SEVERE THUNDERSTORM WATCH 487...488...

VALID 172022Z - 172145Z

A WIND DAMAGE POTENTIAL WILL CONTINUE WITH THE STRONGER CELLS LATE
THIS AFTERNOON FROM THE CNTRL APPALACHIAN MTNS TO THE MID-ATLANTIC
STATES.

SCATTERED STRONG TO SEVERE STORMS ARE ONGOING ACROSS THE CNTRL PARTS
OF WW 487 AND 488. THE ACTIVITY WILL CONTINUE TO FEED OFF OF THE
STRONG INSTABILITY HELPING THE STORMS TO REMAIN NEAR SEVERE LEVELS
AS THEY MOVE EWD ACROSS MD AND SRN PA TOWARD THE COASTAL AREAS LATE
THIS AFTERNOON. A 40 KT MID-LEVEL JET LOCATED ACROSS CNTRL PA IS
ENHANCING SHEAR ACROSS THE REGION WITH A FEW SMALL SUPERCELL STORMS
ONGOING ALONG THE INSTABILITY AXIS IN MD. THE POTENTIAL FOR
SUPERCELLS WILL CONTINUE ESPECIALLY AS THE LOW-LEVEL JET STRENGTHENS
LATE THIS AFTERNOON. WARM TEMPS ALOFT WILL KEEP THE LARGE HAIL
POTENTIAL LOW. THE MAIN THREAT WILL BE WIND DAMAGE CONSIDERING THE
SHEAR AND STEEP LOW-LEVEL LAPSE RATES THAT EXIST ACROSS SRN PA
ACROSS MD INTO NJ AND DE.
