AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
227 AM EST SAT MAR 7 2026
WHAT HAS CHANGED
AS OF 227 AM EST SATURDAY...
NO SIGNIFICANT CHANGES.
KEY MESSAGES
AS OF 227 AM EST SATURDAY...
1. PATCHY FREEZING RAIN AND DRIZZLE INTO THE MORNING.
2. WARM, WINDY AND SHOWERY TODAY AND TONIGHT.
3. THE POTENTIAL FOR SOME RIVER ICE MOVEMENT/BREAKUP AND THE
POTENTIAL FOR A FEW ICE JAMS REMAINS POSSIBLE LATER THIS WEEKEND
INTO EARLY NEXT WEEK.
4. ADDITIONAL CHANCES FOR RAIN AND CONTINUED WARM TEMPERATURES
THROUGH MID WEEK.
DISCUSSION
AS OF 227 AM EST SATURDAY...
KEY MESSAGE 1: TEMPERATURES FOR MOST AREAS EAST OF THE GREENS AND IN
SOUTHERN ESSEX COUNTY NY HAVE FALLEN BELOW FREEZING. INCREASING
MOIST SOUTHEASTERLY FLOW OFF THE ATLANTIC OCEAN WILL CAUSE AREAS OF
MIST AND DRIZZLE IN THOSE AREAS. TEMPERATURES WILL GRADUALLY RISE
ABOVE FREEZING IN THOSE AREAS BUT IT WILL LIKELY TAKE UNTIL MID
MORNING FOR THIS TO HAPPEN IN THE COLDEST PLACES EAST OF THE GREENS.
RAIN SHOWERS WILL ALSO MOVE IN FROM THE WEST LATER IN THE NIGHT AND
TOMORROW MORNING, AND THESE WILL FALL AS FREEZING RAIN IN THOSE
AREAS. HOWEVER, THOSE SHOWERS SHOULD BE MOSTLY RESTRICTED TO CENTRAL
AND NORTHERN AREAS (ORANGE COUNTY AND NORTH) WHERE UP TO AROUND A
TENTH OF AN INCH OF ICE IS EXPECTED. THE REST OF THE AREAS BELOW
FREEZING SHOULD ONLY SEE UP TO A LIGHT GLAZE FROM THE FREEZING MIST
AND DRIZZLE.
KEY MESSAGE 2: AN AREA OF LOW PRESSURE TRACKS OVER THE GREAT LAKES INTO
CANADA DURING THE DAY TODAY, AS A BERMUDA TYPE HIGH REMAINS
ESTABLISHED OFF THE COAST. THIS SETS THE STAGE FOR STRONG WARM AIR
AND MOISTURE ADVECTION. INCREASING WINDS SHOULD PREVENT SIGNIFICANT
FOG FROM FORMING, BUT WITH THE WARM MOIST AIR OVER EXTENSIVE
SNOWPACK IT IS STILL POSSIBLE, ESPECIALLY IN THE PROTECTED HOLLOWS.
TEMPERATURES LOOK TO EVENTUALLY REACH THE 50S FOR MOST AREAS TODAY,
WITH A RUN AT 60 POSSIBLE FOR PARTS OF NORTHERN NEW YORK. WHILE A
ROUND OF SHOWERS IS LIKELY FOR NORTHERN AREAS IN THE MORNING, MOST
OF THE DAY SHOULD BE DRY. THE COLD FRONT COMES THROUGH LATE IN THE
DAY AND OVERNIGHT, BRINGING A ROUND OF POTENTIALLY HEAVY SHOWERS. A
FEW RUMBLES OF THUNDER ARE POSSIBLE OVER NORTHERN NEW YORK. FROM A
HYDRO PERSPECTIVE, THE AMOUNT OF RAIN SHOULD NOT BE OVERLY HIGH. THE
LINE SHOULD BE RELATIVELY FAST MOVING AND MOST OF THE DAY SHOULD BE
DRY. HOWEVER, COMBINED WITH WARM TEMPERATURES AND DEW POINTS
REACHING THE 40S, SIGNIFICANT SNOWMELT WILL OCCUR, THOUGH THE
FASTEST RATES WILL BE PRETTY SHORT LIVED. GUSTY SOUTHERLY WINDS WILL
OCCUR ON SATURDAY, WITH LOCALIZED ENHANCEMENTS IN THE CHAMPLAIN
VALLEY DUE TO CHANNELING AND IN THE NORTHERN ADIRONDACKS DUE TO
DOWNSLOPING. THESE WINDS WILL ALSO ENHANCE SNOWMELT.
KEY MESSAGE 3: THERE DOES NOT LOOK TO BE ENOUGH RAIN OR RIVER ICE MELT
TO CAUSE MUCH IN THE WAY OF FLOODING OR ICE BREAKUP TODAY, THOUGH
VERY LOCALIZED ICE MOVEMENT COULD OCCUR. THE SUSTAINED WARM WEATHER
ON SUNDAY AND MONDAY, THOUGH THANKFULLY WITHOUT ANY ADDITIONAL
PRECIPITATION, MAY CAUSE MORE WIDESPREAD ICE BREAKUP TO START TO
OCCUR, AND THERE IS THE POTENTIAL FOR A FEW ICE JAMS. WHILE
LOCALIZED FIELD FLOODING IS POSSIBLE, SIGNIFICANT FLOODING IS NOT
EXPECTED DUE TO A LACK OF PRECIPITATION ACCOMPANYING THE
SNOWMELT.
KEY MESSAGE 4: A LOW PRESSURE SYSTEM WILL TRACK FROM THE PLAINS
NORTHEASTWARD THROUGH THE GREAT LAKES BRINGING ADDITIONAL
PRECIPITATION TO OUR REGION ESPECIALLY WEDNESDAY BUT ALSO ON
THURSDAY AS THE LOW WILL THEN PUSH EAST OF OUR REGION. AT THIS TIME
LOOKS LIKE WE'LL MAINLY SEE RAIN ON WEDNESDAY, AND THE PRECIPITATION
ON THURSDAY COULD END WITH A CHANGEOVER TO SNOW. STILL A LOT OF
UNCERTAINTY AS WE'RE TALKING ABOUT DAYS 5 AND 6, MODELS LACK
AGREEMENT.TEMPERATURES WILL CONTINUE TO BE WARM FROM TUESDAY NIGHT
THROUGH SATURDAY. WITH WARM AIR AND ADDITIONAL PRECIPITATION WILL
CONTINUE TO WATCH FOR POTENTIAL OF FLOODING DUE TO ICE JAM BREAKUP.
AVIATION /07Z SATURDAY THROUGH WEDNESDAY/
THROUGH 06Z SUNDAY...THROUGH 06Z SUNDAY...MOST SITES ARE CURRENTLY
MVFR AS CEILINGS MOVE INTO THE AREA AHEAD OF APPROACHING RAINFALL.
MPV IS DOWN TO IFR WITH SOME LOW CEILINGS IN THAT AREA. WINDS
CONTINUE TO BE GUSTY OUT OF THE SOUTH AREAWIDE, SOUTHEAST AT RUTLAND
WITH SOME DRAINAGE FLOW INFLUENCE. DEWPOINTS WILL RISE ABOVE
FREEZING AS PRECIPITATION MOVES INTO OUR AREA, AND SOME FOG OVER
SNOWPACK MAY DEVELOP. AREAS EAST OF THE GREENS COULD SEE SOME
FREEZING RAIN AS TEMPERATURES ARE IN THE MID 20S IN THAT AREA. HAVE
UTILIZED PROB 30 GROUPS FOR PRECIPITATION MOVING INTO OUR AREA.
35-45 KNOTS AT 2000 FT WILL LIKELY PRODUCE LLWS AT ALL TERMINALS.
ALTHOUGH IT'S EXPECTED TO INCREASE FURTHER, AREAS LIKE KBTV MAY NOT
TECHNICALLY MEET THRESHOLDS AT TIMES AS SURFACE WINDS INCREASE MOST
IN THE CHAMPLAIN VALLEY WITH GUSTS NEAR TO ABOVE 30 KNOTS AT KBTV.
SHOWER ACTIVITY WILL DIMINISH ABOUT 15- 18Z. SOME IMPROVEMENT TO
CEILINGS IS POSSIBLE, AND DEFINITELY VISIBILITY, AS DAYTIME HEATING
TAKES PLACE. A COLD FRONT WILL APPROACH FROM THE WEST TOWARDS KMSS
ABOUT 22Z SATURDAY.
