AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
159 PM EDT WED MAR 26 2025
SYNOPSIS
SHOWERY WEATHER WILL CONTINUE THROUGH TODAY, WITH SLIGHTLY COLDER
CONDITIONS LEADING TO MINOR SNOW ACCUMULATIONS ACROSS HIGHER
ELEVATIONS. AFTER A COUPLE OF DRIER DAYS TO END THE WEEK, A PATTERN
SHIFT IS EXPECTED FOR THE WEEKEND IN WHICH MORE WIDESPREAD WINTRY
AND WET PRECIPITATION IS EXPECTED.
NEAR TERM /THROUGH THURSDAY/
AS OF 159 PM EDT WEDNESDAY...FORECAST IS GENERALLY IN GOOD
SHAPE. NUMEROUS SNOW SHOWERS CONTINUE THIS AFTERNOON IN EASTERN
NEW YORK INTO NORTHERN VERMONT. LOCALLY MODERATE SNOWFALL RATES
ARE LIKELY IN THE HEAVIER CORES TRACKING FROM NEAR THE
ADIRONDACK HIGH PEAKS NORTHEASTWARD ACROSS MUCH OF NORTHERN
VERMONT, AND WITH WARM SURFACE TEMPERATURES ON TRAVELED ROADS,
STILL EXPECT ANY HAZARDS RELATED TO BURSTS OF LOWER VISIBILITY.
TOYED WITH THE IDEA OF ADDING A SLIGHT CHANCE OF THUNDER AS
INSTABILITY HAS INCREASED AND WILL PEAK OVER THE NEXT FEW HOURS.
PREVIOUS DISCUSSION...AN UPPER LEVEL TROUGH AND A WEAK SURFACE
COLD FRONT WILL PUSH THROUGH THE REGION TODAY, WHICH WILL
CONTINUE TO BRING COOL AND UNSETTLED CONDITIONS THROUGHOUT THE
DAY. SOME INSTABILITY ACROSS THE REGION WILL ALLOW FOR A FEW
HEAVIER SNOW SHOWERS IN THE AFTERNOON, AS WELL AS THE POTENTIAL
FOR SOME GRAUPEL TO MIX IN AS WELL. TEMPERATURES IN THE VALLEYS
SHOULD BE WARM ENOUGH TO SEE PRIMARILY RAIN THIS AFTERNOON. AS
THE COLD FRONT PUSHES THROUGH, WINDS WILL BECOME MORE WESTERLY,
ALLOWING FOR SOME ADDITIONAL UPSLOPE SNOW INTO THE OVERNIGHT
HOURS. IN GENERAL, ACCUMULATIONS WILL BE FAIRLY MINOR, WITH A
DUSTING TO A FEW INCHES ACROSS HIGHER ELEVATIONS. WITH PLENTY OF
CLOUDS AND SHOWERS, TEMPERATURES WILL BE ON THE COOLER SIDE OF
SEASONABLE, WITH HIGHS IN THE MID 30S TO LOWER 40S. OVERNIGHT
LOWS WEDNESDAY NIGHT WILL GENERALLY BE IN THE 20S TO NEAR
FREEZING.
SHOWERS WILL BEGIN TO TAPER OFF HEADING INTO THURSDAY AS A PERIOD OF
BRIEF RIDGING BEGINS TO BUILD IN, BRINGING A PERIOD OF QUIETER
WEATHER IN VERY ACTIVE WEATHER PATTERN. THE DRIER AND QUIET
CONDITIONS WILL CONTINUE FOR MUCH OF THE DAY THURSDAY, WITH SOME
BLUE SKIES AND SUNSHINE POSSIBLE. TEMPERATURES DURING THE DAY
THURSDAY WILL BE RATHER SEASONABLE, WITH HIGHS REACHING THE UPPER
30S TO MID 40S.
SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/
AS OF 408 AM EDT WEDNESDAY...A TROUGH IS EXPECTED TO PUSH THROUGH
THURSDAY NIGHT AND EARLY FRIDAY BRINGING SHOWER CHANCES AND SOME
LIGHT SNOW ACCUMULATIONS OF UP TO 2 INCHES MAINLY TO ELEVATIONS
ABOVE 1000FT. QPF AMOUNTS ARE MEAGER WITH LIQUID EQUIVALENTS FROM
AROUND A HUNDREDTH OF AN INCH UP TO A TENTH OR SO OF AN INCH. SHOWER
INTENSITY IS EXPECTED TO BE WEAK BUT THERE COULD BE A FEW PELLET
SHOWERS AS THE BASE OF THE SHALLOW TROUGH SWINGS BY FRIDAY MORNING.
WINDS WILL GENERALLY BE LIGHT AS BRIEF HIGH PRESSURE CREST LATE
FRIDAY. TEMPERATURES WILL REMAIN AROUND SEASONAL AVERAGES FOR MOST
LOCATIONS WITH HIGHS ON FRIDAY A FEW DEGREES BELOW AVERAGE FOR THE
CHAMPLAIN VALLEY.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
AS OF 408 AM EDT WEDNESDAY...LOW PRESSURE IS PROGGED TO DEVELOP OFF
THE NORTHERN ROCKIES AND TRACK INTO THE REGION SATURDAY. SYSTEM
TRAJECTORY WILL FAVOR A CLIPPER TYPE PATH, BUT STRENGTH WILL BE
INCREASING AS IT IMPINGES UPON PERSISTENT BERMUDA HIGH OFF THE NORTH
CAROLINA COAST. MODELS OVERWHELMINGLY FAVOR A TIGHTENING THERMAL
GRADIENT SATURDAY THROUGH THE WEEKEND INTO EARLY NEXT WEEK. THIS
SETUP WILL PROMOTE AN EXTENDED PERIOD OF PRECIPITATION WITH COLD AIR
PRESSING IN FROM THE NORTH BUT NOT ABLE TO BREAK THROUGH AND DROP
SOUTH OF NEW ENGLAND DUE TO THE AFOREMENTIONED BERMUDA HIGH. AS SUCH
AND WITH SOUTHWESTERLY FLOW IN THE 925-850MB, THE DEVELOPMENT OF A
WARM NOSE IS FAVORED. THIS SUGGESTS THERE IS BETTER THAN AVERAGE
POTENTIAL FOR A PERIOD OF FREEZING RAIN SPREADING NORTHWARD SATURDAY
AND POSSIBLY EXTENDING INTO SUNDAY FOR SOME LOCATIONS. THERE ARE
SOME MODEL DISAGREEMENTS ON DEPTH/EXTENT OF THE WARM LAYER BETWEEN
MODEL SUITES, BUT THE IDEA OF MIXED PRECIPITATION EXISTS IN THEM
ALL. ALSO, THIS WILL BE A WET PERIOD FOR THE NORTH COUNTRY. INITIAL
QPF ESTIMATES ARE FOR OVER AN INCH OF LIQUID FROM SATURDAY THROUGH
MONDAY AS ADDITIONAL WAVES MOVE ALONG THIS PATTERN. WHAT IS UNCLEAR
IS HOW MUCH ICE/SNOW/RAIN WILL OCCUR AS THE QUASI-STATIONARY SURFACE
FRONT WAVERS NORTH AND SOUTH. FOR NOW, PLAN ON AT LEAST SOME SLICK
CONDITIONS SATURDAY INTO SUNDAY LIKELY TRANSITIONS TO FREEZING RAIN
AND RAIN.
MODELS SUPPORT A PATTERN SHIFT TUESDAY INTO WEDNESDAY WITH THE
BERMUDA HIGH SHIFTING EASTWARD. THIS MAY BE A BIT PREMATURE, BUT
UPSTREAM HIGH MOVEMENT DOES SUGGEST THIS SHIFT IN THE
TUESDAY/WEDNESDAY TIMEFRAME AS WELL. TEMPERATURES THROUGH THIS
PERIOD WILL GENERALLY BE AROUND SEASONAL AVERAGE WITH NOT SHARP
TRANSITIONS, JUST OSCILLATING STATIONARY FRONT. HIGHS IN THE UPPER
30S TO LOW/MID 40S AND LOWS IN THE 20S TO LOWER 30S ARE ANTICIPATED.
AVIATION /18Z WEDNESDAY THROUGH MONDAY/
THROUGH 18Z THURSDAY...ALL TERMINALS ARE EXPERIENCING VFR
CONDITIONS AT THIS TIME, BUT WITH COVERAGE OF SNOW SHOWERS
INCREASING, THERE IS A MODERATE CHANCE (30-50%) OF BRIEF
VISIBILITY REDUCTIONS AT BTV, EFK, AND MPV MOVING THROUGH THE
NEXT FEW HOURS. GREATER CHANCE AT SLK, ESPECIALLY TOWARDS 00Z,
OF MORE PERSISTENT SNOW SHOWERS. CEILINGS THROUGH THE PERIOD
WILL LIKELY STAY ABOVE 3000 FEET, ALTHOUGH SOME MVFR CEILINGS
BETWEEN 00Z AND 12Z AT EFK ARE POSSIBLE.
WINDS ARE GENERALLY LIGHT AND VARIABLE, AND SHOULD TREND
WESTERLY. LOCALIZED STRONGER WINDS NEAR PRECIPITATION WILL
CONTINUE TO OCCUR. SOME GUSTS NEAR 20 KNOTS WILL BE POSSIBLE.
