NWS STORM PREDICTION CENTER NORMAN OK
0303 PM CDT MON JUL 07 2025
AREAS AFFECTED...FAR NORTHEAST NEW YORK...NORTHERN VERMONT AND NEW
HAMPSHIRE...AND INTO CENTRAL MAINE
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 072003Z - 072200Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...ISOLATED STRONG THUNDERSTORMS MAY POSE A SEVERE WIND/HAIL
RISK THROUGH THE AFTERNOON AND EARLY EVENING HOURS. THIS THREAT IS
EXPECTED TO REMAIN SUFFICIENTLY ISOLATED TO PRECLUDE WATCH ISSUANCE.
DISCUSSION...LATEST REGIONAL RADAR IMAGERY SHOWS A GRADUAL
MATURATION OF CONVECTION ACROSS FAR NORTHEAST NY AND ACROSS CENTRAL
ME ALONG/AHEAD OF A COLD FRONT. TEMPERATURES WARMING INTO THE LOW
80S WITH DEWPOINTS IN THE UPPER 60S TO LOW 70S IS SLOWLY ERODING
INHIBITION WITH MLCAPE INCREASING TO AROUND 500-1000 J/KG REGION
WIDE. THIS WARMING TREND SHOULD CONTINUE AND WILL PROMOTE FURTHER
THUNDERSTORM INTENSIFICATION OVER THE NEXT COUPLE OF HOURS. 30-40
KNOT MID-LEVEL WINDS IN PROXIMITY TO A WEAKENING UPPER TROUGH ARE
SUPPORTING SUFFICIENT HODOGRAPH ELONGATION FOR ORGANIZED CONVECTION.
WHILE CONVECTIVE MODE WILL LIKELY TRANSITION TO PREDOMINANTLY A
SEMI-ORGANIZED CONVECTIVE BAND DUE TO STRONG FLOW ALONG THE
INITIATING COLD FRONT, AN INITIAL SUPERCELL OR TWO APPEARS POSSIBLE
AND MAY POSE A SEVERE HAIL/WIND RISK THROUGH THE AFTERNOON -
ESPECIALLY ACROSS CENTRAL ME WHERE FORCING FOR ASCENT IS CURRENTLY
MORE NEBULOUS. WITH TIME, STRONG TO SEVERE WINDS SHOULD BECOME THE
PREDOMINANT HAZARD AS A BAND OF STORMS BEGINS TO EMERGE. DESPITE
THESE CONCERNS, THE OVERALL SEVERE THREAT IS EXPECTED TO REMAIN
SUFFICIENTLY ISOLATED TO PRECLUDE WATCH ISSUANCE.
