DISCUSSION
KEY MESSAGE 1...
AFTER A DRY DAY TODAY WITH SHORT WAVE RIDGING AT THE SURFACE,
SHOWERS WILL BECOME LIKELY FROM THIS EVENING THROUGH TONIGHT, AS
A UPPER LEVEL DISTURBANCE MOVES THROUGH. THIS DISTURBANCE WILL
ROTATE AROUND THE SOUTHERN PERIPHERY OF A LARGE SCALE TROUGH IN
PLACE OVER THE GREAT LAKES AND NORTHEAST, WITH THE PARENT UPPER
LOW LOCATED NEAR THE SOUTHERN ONTARIO/QUEBEC BORDER. GUIDANCE
HAS CONTINUED TO TREND HIGHER WITH POPS, NOW 60-70% ACROSS MUCH
OF THE AREA. QPF OF 0.10"-0.25" LOOK TO OCCUR WITHIN THE MOST
PERSISTENT SHOWERS. TEMPERATURES WILL BE COLD ENOUGH FOR WET
SNOW SHOWERS TO MIX IN ACROSS THE WESTERN/SOUTHERN ADIRONDACKS,
WHERE MINOR ACCUMULATIONS < 1" COULD OCCUR ON NON-PAVED
SURFACES. WITH EXTENSIVE CLOUD COVER AND NUMEROUS SHOWERS, THE
THREAT FOR FROST HAS DIMINISHED. BELOW NORMAL TEMPERATURES WILL
PERSIST THROUGH THE WEEKEND WITH THE UPPER LEVEL TROUGH
REMAINING IN PLACE. CHANCES FOR FROST LOOK LOWER EVEN FOR SAT
NIGHT NOW, WITH AND UPPER TROUGH AXIS OVER OUR AREA NORTH/WEST
OF AN OCEAN STORM PASSING JUST SOUTH/EAST OF NEW ENGLAND WITH
MORE CLOUDS AND WIDELY SCATTERED SHOWERS. WITH SOME SHORT WAVE
RIDGING AT THE SURFACE RETURNING SUN NIGHT, THERE MIGHT BE SOME
PATCHY FROST IN THE UPPER HUDSON VALLEY.
KEY MESSAGE 2...
AN UNSETTLED PATTERN IS EXPECTED TO DEVELOP TUE THROUGH THU,
WITH A STRENGTHENING UPPER LEVEL JET AND SW FLOW ALOFT
DOWNSTREAM OF ANOTHER LARGE SCALE UPPER LEVEL TROUGH. AT THE
SURFACE, A COLD FRONT LOOKS TO APPROACH ON TUE, THEN POTENTIALLY
STALL NEAR OUR AREA WED INTO THU, WHILE A POSSIBLE WAVE OF LOW
PRESSURE TRACKS ALONG THE FRONT. THERE ARE STILL WIDELY VARYING
SCENARIOS AMONG THE GUIDANCE AT THIS POINT, BUT THE OVERALL
TREND HAS BEEN FOR A SOUTHWARD SHIFT WITH THE FRONT/WAVE. SHOULD
THIS TREND CONTINUES, IT WOULD RESULT IN LOWERING CHANCES FOR
THUNDERSTORMS WED-THU, BUT THE THREAT FOR HEAVY RAIN WOULD STILL
EXIST AS THE NAEFS ARE STARTING TO INDICATE PWAT ANOMALIES
INCREASING TO +1 TO +2 STDEV. WITH SUCH STRONG KINEMATICS AND
THE APPROACH OF THE UPPER TROUGH, THE THREAT FOR SOME STRONGER
THUNDERSTORMS CANNOT BE RULED OUT THOUGH.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
VFR CONDITIONS CONTINUE FOR ALL TAF SITES THROUGH 02/03Z.
TOWARDS THE END OF THE TAF PERIOD, MVFR CONDITIONS COULD
