NATIONAL WEATHER SERVICE BINGHAMTON NY

SYNOPSIS
ANOTHER AREA OF LOW PRESSURE WILL MOVE THROUGH WEDNESDAY AND
THURSDAY, WHICH WILL BRING ADDITIONAL RAIN AND SNOW SHOWERS. HIGH
PRESSURE BUILDS INTO THE REGION FOR THE WEEKEND, WHICH WILL
BRING DRIER WEATHER TO THE AREA. TEMPERATURES WILL TREND A BIT WARMER
THROUGHOUT THE REMAINDER OF THE WEEK.
NEAR TERM /THROUGH THURSDAY/
HIGH RES MODELS SHOW A SUBTLE RIDGE THAT BUILDS IN TONIGHT IN
THE 925 TO 850 MB LAYER. WITH FLOW GOING FROM NW TO SLIGHTLY SW
LATER THIS EVENING, REMAINING LAKE EFFECT SNOW BANDS WILL SHIFT
NORTH. THAT LOW LEVEL RIDGE AXIS MOVES THROUGH THE REGION
QUICK, WITH SW FLOW AND STRONGER WARM AIR ADVECTION LATE TONIGHT
INTO WEDNESDAY MORNING HELPING GENERATE SOME LIFT. THERE IS NOT
A LOT OF MOISTURE IN PLACE, THOUGH SOME LIGHT SNOW WILL DEVELOP
ALMOST REGION WIDE WITH THE WARM FRONT'S PASSAGE AFTER MIDNIGHT
AND LAST A FEW HOURS. COLD AIR IN PLACE KEEPS PTYPES AS SNOW
THOUGH GIVEN QPF AMOUNTS ARE EXPECTED TO BE LESS THAN 0.05
INCHES, SNOW AMOUNTS WILL LIKELY BE A TRACE WITH UP TO A HALF
INCH AT HIGHER ELEVATIONS IN CNY.
WITH ANOTHER 500 MB SHORTWAVE DROPPING THROUGH THE EASTERN
GREAT LAKES WITH NW FLOW RETURNING BY THE EARLY AFTERNOON. THERE
IS NOT MUCH ADDITIONAL COLD AIR ADVECTING IN WITH THIS
SHORTWAVE AS THE LONG WAVE TROUGH WE HAVE BEEN UNDER BEGINS TO
MOVE EAST. STILL WITH 850 MB TEMPERATURES DOWN AROUND -5C TO -7C
LAKE EFFECT PRECIPITATION WOULD CONTINUE THROUGH WENDESDAY
NIGHT. PRECIPITATION TYPE IS A BIT MORE UNCERTAIN AS THE LAKE
TEMPERATURES ARE STILL WARM AND WITH STEEP LOW LEVEL LAPSE RATES
THANKS TO HEATING FROM THE LAKES, SURFACE TEMPERATURES DOWN
WIND OF THE GREAT LAKES MAY WARM INTO THE MID 30S. HIGHER
ELEVATIONS OF THE TUG HILL AND THE HILLS SOUTH OF THE NY THRUWAY
MAY STILL SEE SOME SNOW ACCUMULATIONS WITH THIS SYSTEM
WEDNESDAY AFTERNOON AND NIGHT BUT THE SNOW TOTALS REMAIN ON THE
LIGHTER SIDE.
SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/
LATE THIS WEEK, WE GET STUCK ON THE BACK SIDE OF THE UPPER
LEVEL LONG WAVE TROUGH AS NORTH ATLANTIC BLOCKING SLOWS ITS
EASTERLY PROGRESS. MOISTURE IS CUT OFF FROM THE NORTHEAST WITH
HIGH PRESSURE OVER THE SE US SO DESPITE CLIPPER SYSTEMS
DESCENDING DOWN THE BACK SIDE OF THE TROUGH INTO THE NORTHEAST,
NOT MUCH PRECIPITATION IS EXPECTED OUTSIDE OF THE LAKE EFFECT
REGIONS. LAKE EFFECT PRECIPITATION THURSDAY AND FRIDAY IS
LOOKING TO ALSO BE MOSTLY RAIN AS THE WARM LAKES AND NOT AS COLD
TEMPERATURES ALOFT KEEPS SURFACE TEMPERATURES ABOVE FREEZING.
STILL, SOME HIGHER ELEVATIONS MAY DO WELL ABOVE 2000 FEET OR SO
BUT BELOW 1200 FEET, MOSTLY RAIN IS EXPECTED. UPPER LEVEL
RIDGING STARTS TO BUILD IN SATURDAY AS WELL AS A PUSH OF MUCH
WARMER TEMPERATURES ALOFT.
LONG TERM /SATURDAY THROUGH TUESDAY/
LATE THIS WEEKEND INTO EARLY NEXT WEEK, THE WEATHER PATTERN
REMAINS ACTIVE WITH FREQUENT SHORTWAVE TROUGHS MOVING THROUGH.
SUNDAY WILL LIKELY BE THE WARMEST DAY OF THE NEXT 7 WITH 850 MB
TEMPERATURES BACK ABOVE 0 AND SOME SUN IS POSSIBLE TO HELP WARM
THINGS UP. SUNDAY NIGHT INTO MONDAY THERE IS GOOD MODEL
AGREEMENT OF A MORE AMPLIFIED SHORTWAVE, POTENTIALLY EVEN A
CLOSED LOW THAT TRIES TO DEVELOP IN THE GREAT LAKES AND MOVE SE
INTO THE MID ATLANTIC. FREEZING RAIN WAS INTRODUCED TO THE
CATSKILLS AND MOHAWK VALLEY SUNDAY NIGHT AS HIGH PRESSURE TO THE
EAST ALONG WITH A WARM FRONT LIFTING IN MAY LEAD TO SOME
OVERRUNNING PRECIPITATION OVER COLDER AIR NEAR THE SURFACE BEING
PUSHED IN FROM THE EAST. LAKE EFFECT RETURNS EARLY NEXT WEEK AS
THIS LOW MOVES EAST WITH GOOD ENSEMBLE AGREEMENT OF COLDER AIR
MOVING BACK IN. THIS NEXT WAVE OF COLDER AIR DOES NOT LOOK AS
COLD AS THE CURRENT EVENT BUT STILL LIKELY COLD ENOUGH THAT THE
LAKE EFFECT PRECIPITATION WILL BE SNOW SO WILL NEED TO BE
WATCHED.
AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
THERE IS SOME LIGHT SNOW OR FLURRIES PUSHING THROUGH CENTRAL NY EARLY
THIS MORNING AND THIS MAY LEAD TO MVFR RESTRICTIONS. HOWEVER, IT

YET. ADDITIONAL RAIN AND SNOW SHOWERS ARE POSSIBLE, ESPECIALLY
