0607 PM CDT SUN JUL 20 2025
AREAS AFFECTED...PARTS OF SOUTHEAST NEW ENGLAND
CONCERNING...SEVERE THUNDERSTORM WATCH 530...
VALID 202307Z - 210030Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 530
CONTINUES.
SUMMARY...DAMAGING WIND REMAINS POSSIBLE THIS EVENING BEFORE STORMS
MOVE OFFSHORE.
DISCUSSION...A SMALL CLUSTER OF STORMS HAS RECENTLY INTENSIFIED AND
PRODUCED SOME REPORTS OF WIND DAMAGE, AND WILL LIKELY CONTINUE TO
POSE SOME SEVERE THREAT TO THE COAST, WITHIN A MODESTLY UNSTABLE AND
FAVORABLY SHEARED ENVIRONMENT. AN EMBEDDED SUPERCELL WITHIN THIS
CLUSTER COULD ALSO POSE A SHORT-TERM THREAT FOR A BRIEF TORNADO.
STORMS FARTHER NORTH INTO EASTERN MA HAVE BEEN SOMEWHAT LESS
ORGANIZED, BUT THE KBOX VWP CURRENTLY SHOWS MODERATE (25-35 KT)
WESTERLY FLOW IN THE 1-3 KM AGL LAYER, AND THERE IS SOME POTENTIAL
FOR THESE STORMS TO LOCALLY INTENSIFY AND POSE AT LEAST A LOCALIZED
WIND-DAMAGE THREAT BEFORE MOVING OFFSHORE LATER THIS EVENING.
