MESOSCALE DISCUSSION 0815
NWS STORM PREDICTION CENTER NORMAN OK
0517 PM CDT WED MAY 27 2015

AREAS AFFECTED...CENTRAL AND NE MAINE

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

VALID 272217Z - 272315Z

PROBABILITY OF WATCH ISSUANCE...20 PERCENT

SUMMARY...ISOLATED SEVERE WIND GUSTS AND LARGE HAIL ARE POSSIBLE
ACROSS CENTRAL AND NE MAINE OVER THE NEXT HOUR OR SO...BUT WATCH IS
NOT NEEDED.

DISCUSSION...A BROKEN LINE OF STRONG TO SEVERE THUNDERSTORMS HAVE
DEVELOPED FROM CENTRAL TO NE MAINE. SOME OF THESE STORMS WILL POSE A
DAMAGING WIND AND ISOLATED LARGE HAIL THREAT DUE TO 500-1000 J/KG OF
MUCAPE...DEEP LAYER SHEAR AROUND 35 KNOTS...AND 20F DEWPOINT
DEPRESSIONS SUPPORTING SOME DOWNBURST POTENTIAL. ISOLATED BRIEF
ROTATION HAS DEVELOPED IN THE STRONGEST STORMS...ALSO LOCALLY
ENHANCING THE DOWNBURST THREAT. A GRADUAL WEAKENING TREND SHOULD
COMMENCE WITHIN THE NEXT HOUR AS STORMS MOVE EAST INTO A MORE STABLE
ATMOSPHERE. GIVEN THE BRIEF TEMPORAL NATURE OF THE SEVERE THREAT...A
WW IS NOT ANTICIPATED AT THIS TIME.
