AREAS AFFECTED...CENTRAL AND SRN OH / SWRN PA / NRN KY / NRN WV AND
THE WV PANHANDLE

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 041439Z - 041645Z

LINE OF THUNDERSTORMS MOVING ACROSS WRN OH / SERN IN ATTM SHOULD
SLOWLY INCREASE IN INTENSITY THROUGH EARLY AFTERNOON.  WW MAY BE
REQUIRED IN THE NEXT 1 TO 2 HOURS.

GENERALLY CLEAR SKY IS EVIDENT ACROSS SRN OH AND INTO SWRN PA / WV /
KY ATTM...WHERE DEWPOINTS REMAIN IN THE UPPER 60S TO NEAR 70. 
CONTINUED HEATING THROUGH THE MORNING WILL ALLOW AIRMASS TO
DESTABILIZE...THOUGH DEGREE OF DESTABILIZATION WILL BE LIMITED DUE
TO WEAK LAPSE RATES EVIDENT ACROSS THIS AREA.

NONETHELESS...MCS REMAINS FAIRLY WELL-ORGANIZED...WITH LEADING
CONVECTIVE LINE EXPECTED TO INTENSIFY OVER THE NEXT COUPLE OF HOURS.
 LATEST ILN /WILMINGTON OH/ VWP SHOWS MODERATE / GENERALLY
UNIDIRECTIONAL LOW- TO MID-LEVEL WIND FIELD...WHICH SHOULD FURTHER
INTENSIFY AS WEAK TROUGH AND ASSOCIATED / STRONGER FLOW ALOFT SHIFTS
EWD INTO THIS REGION.  COMBINATION OF INCREASING INSTABILITY AND
SUFFICIENT DEEP-LAYER WIND FIELD INDICATE THAT LOCALLY DAMAGING
WINDS WILL BECOME INCREASINGLY LIKELY THROUGH THE MORNING AND INTO
EARLY AFTERNOON.
