DISCUSSION
KEY MESSAGE 1...
ENOUGH LIFT AND MOISTURE LOOKS TO BE PRESENT TO DEVELOP AN AREA
OF LIGHT SNOW ACROSS NE PA AND THE SOUTHERN TIER OF NY AROUND
SUNRISE. THIS AREA OF SNOW SHOULD PUSH TO THE NORTHEAST AS LOW
PRESSURE TRACKS UP THE EAST COAST THROUGH TONIGHT. MODELS HAVE
STRUGGLED WITH THE TRACK AND RESULTANT QPF FROM THIS SYSTEM FOR
DAYS NOW. STILL QUITE A RANGE IN HI-RES DATA IS PRESENT AT THIS
LATE STAGE. INCORPORATED ELEMENTS OF THE NAM, RGEM AND HRRR
WHICH DID NUDGE SLIGHTLY HIGHER AMOUNTS OF SNOWFALL FURTHER WEST
TODAY. A QUICK 1 TO LOCALLY 3 INCHES OF SNOW COULD FALL WITH
THE HIGHEST AMOUNTS IN PIKE AND SULLIVAN COUNTIES BY THIS
EVENING. AMOUNTS ARE UNDER ADVISORY CRITERIA BUT A FEW SLICK
SPOTS COULD STILL OCCUR.
KEY MESSAGE 2...
ANOTHER LOW PRESSURE SYSTEM MOVES THROUGH THE GREAT LAKES MONDAY
AND TUESDAY. A FEW OF THE HIRES MODELS DO DEVELOP A FEW SNOW
SHOWERS/SQUALLS MONDAY AFTERNOON AND EVENING. MOISTURE CONTINUES
TO BE LACKING ON MODELED SOUNDINGS FOR A MORE WIDESPREAD
POTENTIAL. HOWEVER, WINDS SHOULD INCREASE ALONG WITH ANOTHER
SHOT OF COLD AIR ENTERING THE REGION. THE MEAN SOUTHWESTERLY
FLOW SHOULD KEEP OUR REGION MAINLY FREE OF LAKE EFFECT SNOW
MONDAY.
TUESDAY CONTINUES TO BE INDICATED AS THE COLDEST DAY WHERE HIGHS
WON'T GET OUT OF THE TEENS. GUSTY WESTERLY WINDS OVER 20 MPH
SHOULD OCCUR AS WELL DROPPING WIND CHILLS BELOW ZERO. WE MAY
REACH COLD WEATHER ADVISORY CRITERIA FOR PARTS OF THE REGION AS
WELL. BRIEF INTERVALS OF WESTERLY FLOW MAY BRING A FEW LAKE
EFFECT SNOW SHOWERS INTO OUR REGION OFF OF LAKE ONTARIO AND/OR
ERIE. IT WOULD BE A VERY FLUFFY SNOW GIVEN THE TEMPERATURES.
KEY MESSAGE 3...
ANOTHER CLIPPER SYSTEM TO LIKELY MOVE THROUGH WEDNESDAY AND
THURSDAY. LIKE THE PAST FEW, SOUTHWESTERLY FLOW WILL LIKELY RING
OUT MOISTURE AS IT IS COMING INTO THE REGION WITH MOISTURE/
ACCUMULATING SNOW INCREASING AGAIN EAST OF OUR REGION. SOME
LAKE EFFECT SNOW COULD MATERIALIZE. HOWEVER, A LOT OF US IN THE
MIDDLE LOOK TO BE LEFT OUT OF ANYTHING MORE THAN A DUSTING
AGAIN.
A MORE FAVORABLE SETUP FOR WIDESPREAD SNOWFALL IS POSSIBLE NEXT
WEEKEND AS LARGE SCALE OVERRUNNING OCCURS AHEAD OF A LOW
PRESSURE SYSTEM TRACKING THROUGH THE SOUTH TO THE EAST COAST.
THE GEFS ARE MOST AGGRESSIVE ON THIS WITH THE EPS A BIT SLOWER
IN THE TIMING. KEPT THE FORECAST CLOSE TO OUR NBM FOR THE TIME
BEING.
AVIATION /12Z SUNDAY THROUGH THURSDAY/
SNOWFALL AND RESTRICTIONS CURRENTLY IMPACTING BGM AND AVP WILL
CONTINUE FOR THE NEXT FEW HOURS, WITH BGM IMPROVING FIRST. ON
RADAR, BGM IS CURRENTLY ON THE EDGE OF THE SNOWFALL, WITH
CURRENT IFR CONDITIONS EXPECTED TO IMPROVE BY 13Z TO MVFR/FUEL
ALT, AND THEN VFR IN THE AFTERNOON. FOR AVP, SNOWFALL AND
RESTRICTIONS LINGER FOR A BIT LONGER, WITH FUEL ALT IMPROVING TO
MVFR BY THE AFTERNOON.
ALL OTHER TERMINALS WILL REMAIN VFR FOR THE 12Z TAF PACKAGE.
OUTLOOK...
MONDAY THROUGH TUESDAY...OCCASIONAL RESTRICTIONS POSSIBLE IN
SCATTERED SNOW SHOWERS, ESPECIALLY ACROSS CENTRAL NY.
WEDNESDAY...AN APPROACHING SYSTEM KEEPS THE CHANCE OF SNOW
SHOWERS AROUND AND ASSOCIATED RESTRICTIONS, MAINLY FOR NY
TERMINALS (LOW CONFIDENCE).
THURSDAY...STRONGER SIGNAL FOR A FRONT OR A LOW PRESSURE SYSTEM
PASSING BY WITH RESTRICTIONS POSSIBLE (MEDIUM CONFIDENCE).
BGM WATCHES/WARNINGS/ADVISORIES
