0713 PM CDT THU JUL 02 2026
AREAS AFFECTED...FAR NORTHEAST NEW YORK INTO NORTHERN VERMONT...NEW
HAMPSHIRE...AND WESTERN MAINE
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 030013Z - 030215Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A BAND OF THUNDERSTORMS CROSS THE INTERNATIONAL BORDER MAY
POSE A DAMAGING WIND THREAT IN THE COMING HOURS ACROSS PORTIONS OF
THE NORTHEAST. WATCH ISSUANCE IS NOT LIKELY, HOWEVER.
DISCUSSION...LATEST MRMS MOSAICS SHOW A BROKEN BAND OF STORMS
MIGRATING EASTWARD ACROSS SOUTHERN QUEBEC AND BEGINNING TO
CROSS/APPROACH THE INTERNATIONAL BORDER. VELOCITY DATA FROM CASBV
SHOWS SOME POCKETS OF STRONGER WINDS, BUT AN OUTFLOW BOUNDARY IS
ALSO NOTED EMANATING FROM THE SOUTHWESTERN FLANK OF THE BAND. THIS
SUGGESTS THAT WHILE SOME SWATHS OF STRONG/DAMAGING WINDS ARE
POSSIBLE IN THE NEAR TERM, THE NEAR-STORM ENVIRONMENT IS NOT
FAVORABLE FOR ADDITIONAL DEVELOPMENT. FURTHERMORE, GOES IR IMAGERY
HAS SHOWN SOME DEGREE OF CLOUD-TOP WARMING OVER THE PAST HOUR,
SUGGESTING A SLIGHT WEAKENING TREND. NONETHELESS, RECENT RAP
MESOANALYSIS DEPICTS 30-40 KNOTS OF EFFECTIVE SHEAR AND AROUND 1500
J/KG MLCAPE ACROSS THE REGION THAT MAY SUPPORT THESE BANDS FOR THE
NEXT COUPLE OF HOURS. BASED ON THE AFOREMENTIONED VELOCITY
OBSERVATIONS, SOME THREAT FOR DAMAGING WINDS WILL LIKELY ACCOMPANY
THESE STORMS. WITH TIME, NOCTURNAL COOLING WILL PROMOTE INCREASING
INHIBITION AND WILL ACT AS A MODULATING FACTOR FOR THUNDERSTORM
INTENSITY, WHICH SHOULD LIMIT THE OVERALL SEVERE RISK AND NEGATE THE
NEED FOR A WATCH.
