DISCUSSION
KEY MESSAGE 1...
SNOW CONTINUES TO MOVE NORTHWARD THROUGH THE REGION THIS
AFTERNOON AS LOW PRESSURE DEVELOPS IN THE DELMARVA REGION BY
EVENING. SOMEWHAT WARMER AND MOISTER AIR WILL CONTINUED TO BE
ADVECTED INTO THE REGION THROUGH THE EARLY EVENING. FEGN FORCING
FROM 600-800 MB CONTINUES TO SUPPORT THE POTENTIAL FOR SNOWFALL
RATES FROM BANDING AROUND 2 INCHES PER HOUR FOR MOST OF CNY AND
NEPA FROM EARLY THIS AFTERNOON INTO THE EARLY EVENING HOURS.
THIS SIGNAL IS STILL SHOWING UP ON MOST OF THE HIRES MODEL
GUIDANCE. LIGHTER SNOW SHOWERS SHOULD LAST THROUGH THE OVERNIGHT
AND MONDAY. OVERALL, TIMING CONTINUES TO TREND SLIGHTLY FASTER.
MODELED SOUNDINGS AND OBSERVATIONS SEEM TO INDICATE RATIOS OF
15-20:1 TOO. THESE STILL MAY LOWER SOME IN THE WYOMING VALLEY AS
WARMER AIR ALOFT MOVES IN. A CHANGEOVER TO SLEET IS LOOKING TO
BE LESS OF A POTENTIAL NOW THOUGH. OVERALL, TOTALS HAVE COME UP
A BIT FOR NEPA (10-15IN) AND ARE ABOUT THE SAME IN CNY (15-20IN).
TEMPERATURES LOOK TO REMAIN IN THE SINGLE DIGITS TODAY, PERHAPS
RISING INTO THE TEENS TONIGHT. WITH A LITTLE BIT OF WIND,
SINGLE DIGIT TO BELOW ZERO WIND CHILLS ARE POSSIBLE AS WELL.
COLD WEATHER CONTINUES MONDAY WITH TEMPERATURES STILL MAINLY IN
THE TEENS FOR HIGHS, MAYBE A FEW LOW 20'S. OUR MAIN CONCERN
WILL BE FROM BLOWING SNOW AS WINDS INCREASE DURING THE
AFTERNOON HOURS. SOME ADDITIONAL SNOW SHOWERS SHOULD OCCUR AS
WELL. WITH A WEST TO NORTHWEST FLOW SOME LAKE RESPONSE IS
LIKELY TO OCCUR OFF OF LAKE ONTARIO BRINGING A HIGHER COVERAGE
OF SNOW SHOWERS TOWARD THE NY THRUWAY CORRIDOR. RATIOS SHOULD
CONTINUE TO HIGH, SO ANOTHER INCH OR TWO OF FLUFF IS QUITE
POSSIBLE BY MONDAY NIGHT.
KEY MESSAGE 2...
AS THE UPPER TROUGH MENTIONED ABOVE DEPARTS TO THE EAST AND WEAK
RIDGING BUILDS IN ALOFT, WINDS BECOME MORE WEST THEN SOUTHWESTERLY
EARLY TUESDAY MORNING WHICH WILL LIFT THE LAKE EFFECT SNOW TO THE
NORTH OF THE I-90 CORRIDOR TOWARD DAYBREAK. WIND GUSTS OF 20-30 MPH
ARE STILL LIKELY MONDAY NIGHT, WITH AREAS OF BLOWING SNOW EXPECTED,
ESPECIALLY BEFORE 4 AM EST. LOWS MONDAY NIGHT WILL BE IN THE SINGLE
DIGITS TO A FEW DEGREES BELOW ZERO. WIND CHILLS BE VERY COLD MONDAY
NIGHT INTO TUESDAY MORNING, BETWEEN 0 TO 15 BELOW FOR MOST
LOCATIONS. COLD WEATHER ADVISORIES MAY BE NEEDED IF CONFIDENCE
INCREASES IN THESE VERY COLD WIND CHILL VALUES.
A WEAKENING CLIPPER APPROACHING FROM THE NORTH AND WEST TUESDAY CAN
LEAD TO SOME SCATTERED LIGHT SNOW SHOWERS ACROSS THE AREA,
ESPECIALLY OVER CNY. THIS SYSTEM WILL BRING WITH IT A REINFORCING
SHOT OF COLD AIR AND AS THE UPPER LEVEL SHORTWAVE WITH THIS
DISTURBANCE SWINGS THROUGH, WEST TO NORTHWESTERLY WINDS ARE EXPECTED
TO LEAD TO LAKE EFFECT SNOW SHOWERS DROPPING BACK SOUTH INTO CNY
TUESDAY NIGHT INTO WEDNESDAY MORNING. THIS LAKE EFFECT SNOW BAND
COULD BE RATHER WELL ORGANIZED ALONG OR JUST NORTH OF I-90 FOR A
TIME OVERNIGHT INTO WEDNESDAY MORNING, WITH SEVERAL INCHES OF SNOW
POSSIBLE HERE.
HIGHS TUESDAY RANGE FROM THE UPPER SINGLE DIGITS TO MID-TEENS. LOWS
TUESDAY NIGHT RANGE FROM ABOUT 5 DEGREES ABOVE TO 5 DEGREES BELOW
ZERO AROUND THE AREA.
THE NEXT DEEPER 500MB TROUGH DROPS INTO THE REGION WEDNESDAY NIGHT
AND THURSDAY, ALONG WITH A POTENTIAL CLIPPER SYSTEM. THIS WILL KEEP
CHANCES FOR SNOW SHOWERS IN THE FORECAST, ESPECIALLY ACROSS CNY. AT
THIS TIME, MODEL GUIDANCE KEEPS A RATHER STAGNANT PATTERN OVER THE
AREA RIGHT INTO NEXT WEEKEND, WITH THE A 500MB TROUGH IN PLACE
ACROSS THE GREAT LAKES AND NORTHEAST BRINING OCCASIONAL CLIPPER
SYSTEMS AND LAKE EFFECT SNOW SHOWERS OFF OF LAKE ONTARIO. WITH THE
NBM BEING UNDERDONE WITH THIS LAKE EFFECT SETUP, THE CANADIAN WAS
BLENDED INTO THE FORECAST THROUGH THE END OF THE WEEK TO INCREASE
POPS, QPF AND SNOW AMOUNTS IN THE FAVORED LOCATIONS. TEMPERATURES
REMAIN STEADY, WITH LOWS 5 BELOW TO 5 ABOVE ZERO, AND HIGHS IN THE
UPPER SINGLE DIGITS TO TEENS THROUGH AT LEAST FRIDAY. TEMPERATURES
MODERATE SOME, CLOSER TO, BUT STILL BELOW AVERAGE BY NEXT WEEKEND.
HIGHS WILL BE IN THE UPPER 10S TO 20S BY SUNDAY UNDER PARTLY
SUNNY SKIES.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
WIDESPREAD SNOW WITH LIFR/VLIFR CONDITIONS ACROSS THE REGION.
THIS IS EXPECTED TO CONTINUE THROUGH THE AFTERNOON AS HEAVIER
SNOW MOVES INTO THE AREA. RESTRICTIONS SHOULD RISE TO IFR/LIFR
BY MID EVENING AS THE HEAVIER SNOW MOVES OUT OF THE AREA. SNOW
SHOULD END AT ELM/AVP DURING THE OVERNIGHT HOURS WITH MVFR
CONDITIONS STICKING AROUND. BGM/ITH/SYR/RME WILL CONTINUE TO SEE
SNOW SHOWERS THROUGH THE OVERNIGHT HOURS WITH IFR RESTRICTIONS
EXPECTED. BGM AND ITH SHOULD LIFT TO MVFR BY MID MORNING WHILE
SYR/RME REMAIN IFR AS SNOW REMAINS.

EFFECT POSSIBLE WITH ASSOCIATED RESTRICTIONS. BLOWING SNOW IN
THE AFTERNOON AS NW WINDS GUSTS 25-35 MPH AT TIMES.
