AREAS AFFECTED...A LARGE PORTION OF THE NORTHEAST
CONCERNING...SEVERE THUNDERSTORM WATCH 501...502...
VALID 102251Z - 102345Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
501...502...CONTINUES.
NUMEROUS STRONG/SEVERE THUNDERSTORMS HAVE EVOLVED ACROSS A LARGE
PORTION OF THE NORTHEASTERN U.S. FROM UPSTATE NY...SWD INTO MD.
THIS ACTIVITY IS EXPANDING IN AREAL COVERAGE WITHIN A BROADER ZONE
OF LOW LEVEL CONFLUENCE AND VERY STEEP LOW LEVEL LAPSE RATES.
BOUNDARY LAYER AIRMASS IS QUITE WARM AND UNTIL SIGNIFICANT
CONVECTIVE OVERTURNING OCCURS AN ENHANCED SEVERE THREAT WILL
PERSIST. OVER THE NEXT FEW HOURS IT APPEARS MULTIPLE MCS'S WILL
EMERGE ACROSS THIS REGION AS DEEP BROAD SWLY FLOW FORCES
THUNDERSTORM COMPLEXES INTO SRN NEW ENGLAND. IT'S NOT ENTIRELY
CLEAR HOW UPDRAFTS WILL INTERACT WITH SEA BREEZE OVER SRN NEW
ENGLAND...BUT AIRMASS REMAINS BUOYANT AND SHOULD SUPPORT
STRONG/SEVERE UPDRAFTS.
