AREAS AFFECTED...PORTIONS OF CENTRAL AND EASTERN NY
CONCERNING...SEVERE THUNDERSTORM WATCH 631...
VALID 272022Z - 272215Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 631
CONTINUES.
SUMMARY...THROUGH 22-23Z, THE GREATEST SEVERE WEATHER THREAT IS
EXPECTED TO SPREAD EAST FROM THE EASTERN FINGER LAKES AND VICINITY
TOWARD THE HUDSON VALLEY/CAPITAL DISTRICT. DAMAGING WINDS WILL
REMAIN THE PRIMARY HAZARD, WITH MARGINALLY SEVERE HAIL AND A BRIEF
TORNADO OR TWO ALSO POSSIBLE.
DISCUSSION...DESPITE CONSIDERABLE CLOUDINESS, WHICH HAS SLOWED MORE
ROBUST AIR MASS DESTABILIZATION, BROKEN BANDS OF SEMI-DISCRETE
STORMS HAVE EVOLVED OVER PORTIONS OF CENTRAL NY, WITH THE MOST
INTENSE STORMS EXTENDING FROM NORTH OF BINGHAMTON TO NORTHEAST OF
UTICA AS OF 2015Z. THAT ACTIVITY IS OCCURRING WITHIN A KINEMATIC
ENVIRONMENT FEATURING 30-35 KT OF DEEP-LAYER SHEAR, PER CURRENT KBGM
VWP.
LATEST MODEL GUIDANCE SUGGESTS THAT STORMS WILL CONTINUE TO
INTENSIFY OVER THE NEXT 1-3 HOURS WHILE PROGRESSING TOWARD THE
HUDSON VALLEY/CAPITAL DISTRICT. HOWEVER, VISIBLE SATELLITE IMAGERY
SHOWS THE PRESENCE OF WAVE-TYPE CLOUDS OVER THE CATSKILLS, WHICH ARE
INDICATIVE OF SOME DEGREE OF STABILITY. ON THE CONDITION THAT
SUFFICIENT INSTABILITY EXISTS, LOCALLY BACKED SURFACE WINDS AND
RESULTANT STRONGER LOW-LEVEL SHEAR EVIDENT IN THE KENX VWP (COMPARED
TO KBGM) MAY SUPPORT AN INCREASED SUPERCELL RISK LATE THIS
AFTERNOON. DAMAGING WIND GUSTS WILL REMAIN THE PREDOMINANT HAZARD,
THOUGH MARGINALLY SEVERE HAIL AND A BRIEF TORNADO OR TWO ARE ALSO
POSSIBLE.
