AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
715 PM EDT MON MAR 23 2026
WHAT HAS CHANGED
AS OF 228 PM EDT MONDAY...
TEMPERATURES FOR TODAY HAVE BEEN REDUCED, AND THE CHANCES FOR
SNOW SHOWERS IN THE NORTHEAST KINGDOM INCREASED. OTHERWISE,
TEMPERATURES ON THURSDAY HAVE BEEN TRENDING WARMER WITH
NORTHWARD SHIFTS IN TRACK. NO ADDITIONAL CHANGES WERE NEEDED.
KEY MESSAGES
AS OF 228 PM EDT MONDAY...
1. ISOLATED TO SCATTERED SNOW SHOWERS EXPECTED LATER THIS
AFTERNOON AND EVENING, WITH COLD TEMPERATURES TOMORROW MORNING.
2. WARMING UP FOR THE MIDWEEK WITH A PAIR OF SYSTEMS WITH LIGHT
PRECIPITATION.
3. RAIN THURSDAY NIGHT INTO FRIDAY FOLLOWED BY BRIEF COLD.
DISCUSSION
AS OF 228 PM EDT MONDAY...
KEY MESSAGE 1: VERMONT AND NORTHERN NEW YORK HAVE BEEN SHROUDED IN
CLOUD COVER. LATER THIS AFTERNOON AND EVENING, AN INVERTED SURFACE
TROUGH AND WEAK SURFACE INSTABILITY COINCIDENT WITH PASSAGE OF AN
UPPER TROUGH AXIS WILL CAUSE COVERAGE OF SNOW SHOWERS TO INCREASE.
EMBEDDED HEAVIER ELEMENTS ARE POSSIBLE, BUT MOST ACTIVITY WILL BE
FAIRLY LIGHT. A QUICK COATING OF SNOW UP TO LOCALIZED 1-2" AMOUNTS
ARE POSSIBLE, WITH THIS MOST LIKELY IN THE NORTHEAST KINGDOM OF
VERMONT. HIGHER ELEVATIONS MAY OBSERVE INTERMITTENT ACTIVITY, AND
HAVE GREATER CHANCES FOR 1-3" OF SNOW, ESPECIALLY NORTHERN SUMMITS.
EVENTUALLY, DRY AIR DOES WIN OUT. SNOW SHOWERS WILL GRADUALLY TAPER
TO THE SUMMITS OVERNIGHT. NORTHWEST WINDS WILL BRING IN COLD AIR
THAT WILL PUSH LOW TEMPERATURES INTO THE TEENS TO LOWER 20S TO OPEN
UP TUESDAY. TUESDAY WILL AT LEAST BE DRY, WITH MODERATING
TEMPERATURES.
KEY MESSAGE 2: EARLY WEDNESDAY MORNING, A POSITIVE TILT TROUGH WILL
SHUFFLE EAST. SURFACE LOW PRESSURE WILL RESIDE IN FAR NORTHERN
QUEBEC PROVINCE WITH THE TAIL END OF ITS COLD FRONT JUST NOSING INTO
NORTHERN NEW YORK AND NORTHERN VERMONT. TYPICALLY, THESE SYSTEMS
HAVE THEIR DYNAMICS WELL REMOVED FROM THE REGION, BUT THERE'S A
SOMEWHAT FAVORABLE ALIGNMENT OF A JET STREAK JUST SOUTH AND A
REASONABLY DEFINED AXIS OF DEFORMATION/FRONTOGENESIS. MOISTURE IS
STILL LACKING, THOUGH. BUT SOME LIGHT SNOW SHOWERS WILL BE POSSIBLE
ALONG THE INTERNATIONAL BORDER. COOL AIR BACK BEHIND THIS FRONT WILL
BE SHORT-LIVED, WITH DEEP SOUTHWESTERLY FLOW TAKING HOLD DURING THE
AFTERNOON. TEMPERATURES WILL START CLIMBING INTO THE UPPER 30S TO
MID 40S ON WEDNESDAY.
THEN, A WARM FRONT WILL ANGLE NORTHWARDS WEDNESDAY NIGHT INTO
THURSDAY. THERE COULD BE SOME LIGHT SNOW. THEN A TRANSITION TO RAIN
WILL TAKE PLACE AS WE ENTER THE WARM SECTOR. OVERALL IMPACTS APPEAR
MINOR, AND THERE'S SOME DEGREE OF UNCERTAINTY TO THE TRACK SPEED AND
INTENSITY WHICH AFFECTS THURSDAY AFTERNOON. THURSDAY COULD FEATURE
SOME BRIEF DRYING AS THE WARM FRONT PULLS AWAY, OR RAIN SHOWERS MAY
START CREEPING IN TOWARDS EVENING. THURSDAY'S HIGH TEMPS WILL LIKELY
RISE INTO THE MID 40S TO MID 50S.
KEY MESSAGE 3: THE NORTHWARD SHIFT IN MODEL GUIDANCE CONTINUES FOR THE
THURSDAY NIGHT INTO FRIDAY SYSTEM. TEMPERATURES RISE ABOVE FREEZING
BEHIND THE WARM FRONT ON THURSDAY, LIKELY EVEN IN THE MOUNTAINS. AN
AREAS OF RAIN LOOKS TO DEVELOP AHEAD OF AND WITH THE COLD FRONT.
THIS LOOKS TO MELT THE SNOW OUTSIDE THE HIGHER ELEVATIONS BUT WITH
RELATIVELY LOW QPF, LOW DEW POINTS, AND LOW SWE, FLOODING IS NOT
EXPECTED. TEMPERATURES DROP PRETTY DRAMATICALLY BEHIND THE COLD
FRONT AND THE HIGHS SHOULD OCCUR AROUND MIDNIGHT FOR MOST PLACES.
DAYTIME HIGHS LOOK TO BE IN THE 20S AND 30S ON FRIDAY, BEFORE
TEMPERATURES DROP BACK INTO THE SINGLE DIGITS AND TEENS FRIDAY
NIGHT. PLATTSBURGH HAS VERY LOW HANGING FRUIT FOR A RECORD LOW
FRIDAY NIGHT, WITH TEMPERATURES ONLY NEEDING TO DROP BELOW 10 TO SET
IT. ACROSS THE LAKE IN BURLINGTON WHERE THERE IS A MUCH LONGER
PERIOD OF RECORD, THE RECORD LOW IS -5.
AVIATION /00Z TUESDAY THROUGH SATURDAY/
THROUGH 00Z WEDNESDAY...CONDITIONS ARE SLOWLY IMPROVING ACROSS
MANY OF OUR TAF SITES THIS EVENING, AS LIGHT SNOW SHOWER
ACTIVITY CONTINUES. CONDITIONS RANGE FROM MVFR AT SLK/MPV/BTV/EFK
AND RUT TO VFR AT MSS/PBG WITH MOSTLY VFR VISIBILITIES, EXCEPT
SOME LINGERING MVFR AT EFK/MPV. SOUNDING DATA SUGGESTS LOWERING
CIGS TOWARD IFR AGAIN AT RUT AROUND 04Z THIS EVENING, FEEL THE
PROBABILITY OF THIS OCCURRING IS 40-60%, SO HAVE UTILIZED A
TEMPO GROUP TO COVER THIS POTENTIAL. NEXT CHANCE FOR IFR WOULD
BE EFK AND MPV THIS EVENING IN LIGHT SNOW AND LOWERING CIGS, BUT
FEEL GIVEN LATEST TRENDS, THIS IS A 30 TO 40% PROBABILITY, SO
HAVE MOSTLY KEPT OUT OF TAF ATTM. OTHERWISE, ANY MVFR CIGS AT
SLK SHOULD IMPROVE TO VFR BY MIDNIGHT WITH VFR CONDITIONS
TRENDING AT ALL SITES BY 12Z TUES AND PREVAILING ALL DAY. WINDS
ARE GENERALLY FROM THE NORTHWEST AT 4 TO 8 KNOTS OVERNIGHT,
BEFORE SHIFTING TO THE SOUTHWEST AFTER 21Z TUES AT 5 TO 10
KNOTS.
