AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
139 AM EDT MON MAR 31 2025
SYNOPSIS
THE FREEZING RAIN THREAT HAS COME TO AN END WITH A PERIOD OF
WET WEATHER EXPECTED TO CONTINUE THROUGH MONDAY AFTERNOON. A
BRIEF PERIOD OF DRIER WEATHER IS EXPECTED FOR TUESDAY AND MUCH
OF WEDNESDAY BEFORE ANOTHER FRONTAL SYSTEM BRINGS A MIX OF RAIN,
SNOW, SLEET, AND FREEZING RAIN BACK TO THE REGION WEDNESDAY
NIGHT AND THURSDAY. UNSETTLED WEATHER LOOKS TO CONTINUE ON
FRIDAY AND THIS UPCOMING WEEKEND WITH CHANCES FOR RAIN AND/OR
SNOW SHOWERS EACH DAY.
NEAR TERM /THROUGH TUESDAY/
AS OF 124 AM EDT MONDAY...NO MAJOR CHANGES TO THE FORECAST WITH
THIS UPDATE. SOME LIGHT RAIN SHOWERS CONTINUE ACROSS THE REGION,
WITH TEMPERATURES CONTINUING TO WARM OVERNIGHT.
PREVIOUS DISCUSSION...PRECIPITATION CONTINUES TO LIFT NORTH
THIS AFTERNOON WITH WARM AIR EVER SO SLIGHTLY BEGINNING TO
DISPLACE THE BELOW FREEZING AIR THAT HAS BEEN ENTRENCHED ACROSS
THE REGION OVER THE PAST 36 HOURS. THIS IS ALLOWING FOR FREEZING
RAIN TO CHANGE TO PLAIN RAIN BEFORE ULTIMATELY ENDING. WE HAVE
BEEN ABLE TO SLOWLY CANCEL THE WARNINGS AND ADVISORIES ACROSS
THE REGION AS A RESULT BUT IT SEEMS PLENTY OF DAMAGE WAS SEEN
WITH THE ICE ACROSS PORTIONS OF NORTHERN NEW YORK AND VERMONT.
BASED ON THE LATEST OBSERVATIONS, THERE ARE ONLY A HANDFUL OF
PLACES AT OR BELOW FREEZING BUT ARE EXPECTED TO RISE ABOVE
FREEZING RIGHT AT PRECIPITATION ENDS. THUS, WE HAVE DECIDED TO
GO AHEAD AND CANCEL ALL WARNINGS AND ADVISORIES WITH THE
ISSUANCE OF THIS FORECAST PACKAGE.
LOOKING FORWARD, WE WILL CONTINUE TO SEE DISORGANIZED RAIN
SHOWERS THROUGH THE OVERNIGHT PERIOD AS WE WILL SEE A SERIES OF
SHORTWAVE TRAVERSE THE WESTERN PERIPHERY OF THE UPPER LEVEL
RIDGE. GIVEN CONTINUED WARM AIR ADVECTION, WE WILL SEE
TEMPERATURES SLOWLY RISE THROUGHOUT THE OVERNIGHT PERIOD. WE
WILL SEE TEMPERATURES "SKYROCKET" TOMORROW AFTERNOON INTO THE
60S WITH A FEW PLACES NEARING 70 DEGREES ACROSS SOUTHERN
VERMONT. MODEL SOUNDINGS AND HREF MEMBERS ARE HINTING AT 100-500
J/KG OF CAPE DEVELOPING WITHIN THE WARM SECTOR, MAINLY ACROSS
VERMONT. THIS MAY SUPPORT SOME EMBEDDED THUNDERSTORMS AHEAD OF A
COLD FRONT TUESDAY AFTERNOON. OVERALL RAINFALL AMOUNTS WILL
RANGE FROM A QUARTER TO HALF OF AN INCH BUT COULD SEE VERY
LOCALIZED AMOUNTS UP TO AN INCH WHERE THUNDERSTORMS DEVELOP. FOR
MORE ON FLOODING POTENTIAL, PLEASE SEE THE HYDRO SECTION BELOW.
WE WILL ALSO SEE SOME GUSTY WINDS ON MONDAY AHEAD OF THE
AFOREMENTIONED COLD FRONT WITH WINDS GUSTING BETWEEN 15 AND 30
MPH WITH GUSTS UP TO 40 MPH ACROSS LAKE CHAMPLAIN. THESE WINDS
ARE EXPECTED TO WEAKEN SLIGHTLY AND SHIFT TO THE NORTHWEST IN
THE WAKE OF THE COLD FRONT MONDAY EVENING.
SHORT TERM /TUESDAY NIGHT/
AS OF 243 PM EDT SUNDAY...OUTSIDE OF SOME MORNING SNOW OR RAIN
SHOWERS, TUESDAY IS SHAPING UP TO BE DRY WITH SEASONALLY COOL
TEMPERATURES IN THE 30S. MOST SNOW SHOWERS WILL BE LIMITED TO
THE HIGH TERRAIN WITH SNOW ACCUMULATIONS WELL UNDER AN INCH
EXPECTED. ALTHOUGH SURFACE HIGH PRESSURE BEGINS TO NOSE INTO THE
REGION ON TUESDAY, WE SHOULD STILL SEE ENOUGH GRADIENT FLOW TO
SEE NORTHWEST WINDS OF 10 TO 20 MPH THROUGHOUT THE DAY.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
AS OF 243 PM EDT SUNDAY...WHILE WEDNESDAY LOOKS TO START OFF
RELATIVELY CALM, HIGH PRESSURE WILL DEPART TO THE NORTHEAST AS A
TROUGH AND ASSOCIATED PRECIPITATION APPROACHES BY WEDNESDAY
NIGHT. TEMPERATURES LOOK TO BE IN THE LOW 40S FOR HIGHS AND MID
TO LOW 30S FOR THE OVERNIGHT LOWS. PRECIPITATION LOOKS TO BEGIN
AS SNOW ACROSS MOST OF THE REGION, WITH SOME RAIN MIXING IN
ACROSS THE ST. LAWRENCE AND CHAMPLAIN VALLEYS. A WARM FRONT WILL
LIFT INTO THE REGION FROM THE SOUTH WEDNESDAY NIGHT WHICH WILL
DRAW IN ELEVATED WARM AIR, HOWEVER, WITH THE DEPARTING HIGH TO
THE NORTHEAST AND NORTHERLY COOLER AIR AT THE SURFACE, A DEEP
WARM NOSE ALOFT LOOKS TO FORM WITH A COOL SURFACE. CONFIDENCE
HAS GROWN IN THE WINTRY MIX POTENTIAL AS COLD AIR LOOKS TO
REMAIN ENTRENCHED EAST OF THE GREENS AND WITHIN THE ADIRONDACKS
WEDNESDAY NIGHT. ALL WINTER PRECIPITATION TYPES LOOK TO BE IN
POSSIBLE. BY THURSDAY MORNING, STRONGER WAA WILL ALLOW A
CHANGEOVER TO ALL RAIN, WHICH LOOKS TO PERSIST THROUGH THURSDAY
NIGHT AS A COLD FRONT HELPS TO CLEAR OUT THE REGION OF MOISTURE.
TEMPERATURES THURSDAY AND FRIDAY WILL BE SEVERAL DEGREES ABOVE
AVERAGE WITH HIGHS IN THE 50S AND 60S. BEYOND FRIDAY
TEMPERATURES LOOK TO WILL FALL SLIGHTLY BELOW AVERAGE AS A BROAD
RIDGE OF HIGH PRESSURE FILTERS IN.
AVIATION /06Z MONDAY THROUGH FRIDAY/
THROUGH 06Z TUESDAY...VARIABLE FLIGHT CONDITIONS CURRENTLY
PREVAIL ACROSS THE REGION TONIGHT, WITH TERMINALS RANGING FROM
LIFR TO VFR WITH LIGHT RAIN SHOWERS MOVING ACROSS, ALTHOUGH MOST
TERMINALS ARE CURRENTLY EXPERIENCING MVFR CEILINGS AND
CONDITIONS. CEILINGS HAVE BEEN THE MAIN REASON FOR REDUCED
FLIGHT CONDITIONS, RANGING FROM 300 FT AGL AT KMSS TO 3000+ FT
AGL AT KPBG, WITH MOST OF THE REGION CURRENTLY SEEING CEILINGS
BETWEEN 1500 TO 2800 FT AGL. MVFR CONDITIONS ARE EXPECTED TO
PREVAIL FOR MOST OF THE FORECAST PERIOD, WITH SOME ADDITIONAL
CHANCES FOR LIGHT RAIN SHOWERS. SOUTHERLY WINDS WILL GENERALLY
BE BETWEEN 5 TO 15 KNOTS, BECOMING MORE WESTERLY THROUGHOUT THE
DAY WITH GUSTS OF 15 TO 25 POSSIBLE. WIDESPREAD LLWS CONTINUES
TO BE A CONCERN FOR A LARGE PORTION OF THE FORECAST PERIOD,
BEFORE IMPROVING AFTER 00Z OR SO.

HYDROLOGY
AS OF 245 PM EDT SUNDAY...RECENT MODEL DATA CONTINUES TO
SUGGEST WE WILL SEE BETWEEN A QUARTER AND HALF OF AN INCH OF
RAINFALL ON MONDAY WITH THE POTENTIAL FOR SOME LIGHT RAIN
SHOWERS TONIGHT AS WELL. GIVEN RECENT SNOWFALL AND TEMPERATURES
IN THE 60S TOMORROW, THE COMBINATION OF SNOW MELT AND ADDITIONAL
RAINFALL IS EXPECTED TO CAUSE SHARP RISES ON AREA RIVERS. WHILE
WIDESPREAD FLOODING IS NOT ANTICIPATED AT THIS TIME, THE LATEST
RIVER FORECASTS BRING THE EAST BRANCH OF THE AUSABLE RIVER AT
AUSABLE FORKS AND THE MAD RIVER AT MORETOWN RIGHT TO MINOR FLOOD
STAGE. SEVERAL OTHER RIVERS WILL LIKELY APPROACH BANKFULL AS
WELL. CRESTS SHOULD GENERALLY OCCUR MONDAY NIGHT INTO EARLY
TUESDAY.
