AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
1001 AM EDT SAT MAY 24 2025
SYNOPSIS
A STALLED OUT LOW PRESSURE SYSTEM WILL KEEP CLOUDS IN PLACE
WHILE BRINGING MORE PERIODS OF WIDESPREAD SHOWERS AND
UNSEASONABLY COOL WEATHER TODAY. LESS RAIN IS EXPECTED ON
SUNDAY, AS SHOWERS WILL BE MORE SCATTERED IN NATURE WHILE
TEMPERATURES WARM CLOSER TO NORMAL. DRY, SUNNY, AND WARM
CONDITIONS WILL RETURN FOR MEMORIAL DAY THROUGH WEDNESDAY, THEN
RAIN CHANCES INCREASE BEGINNING THURSDAY.
NEAR TERM /THROUGH SUNDAY/
AS OF 955 AM EDT SATURDAY...WE CONTINUE TO SEE WAVES OF SHOWERS
THIS MORNING AS MOISTURE AND WEAK SHORTWAVES ROTATE AROUND THE
UPPER LOW LOCATED OVER NE MAINE/NW NEW BRUNSWICK. WHILE THERE'S
BEEN A RELATIVE LULL FOR A TIME, EXPECT THINGS TO BECOME MORE
WIDESPREAD/NUMEROUS BY THIS AFTERNOON. LIKE YESTERDAY,
TEMPERATURES ARE CURRENTLY IN THE 40S IN MOST AREAS THIS
MORNING, THOUGH A FEW SPOTS ARE REPORTING 50F OR A TOUCH WARMER
AT THIS HOUR. REGARDLESS, DON'T ANTICIPATE MUCH WARMING TODAY,
THOUGH THERE COULD BE A FEW BREAKS IN THE CLOUD COVER,
ESPECIALLY ON THE E/SE SLOPES OF THE ADIRONDACKS/GREENS. WINDS
WILL BE A LITTLE STRONGER YESTERDAY, THOUGH STILL RELATIVELY
LIGHT AT 10 MPH OR LESS. HAVE MADE SOME TWEAKS TO POPS AND WINDS
TO MATCH THE LATEST TRENDS, BUT OVERALL THE FORECAST REMAINS IN
GOOD SHAPE THIS MORNING.
PREVIOUS DISCUSSION... WE ARE PLAYING THE SAME TUNE TODAY AS
YESTERDAY FOR THE MOST PART. IT WILL BE WET, INCLUDING PERIODS
OF STEADIER RAIN, AND UNSEASONABLY COOL AND CLOUDY WEATHER IS
GUARANTEED. DISORGANIZED BANDS OF SHOWERS WILL PINWHEEL IN FROM
THE NORTH AND EAST AROUND THE OLD COASTAL LOW, NOW STALLED OUT
JUST EAST OF NORTHERN MAINE. TIMING OF STEADIER SHOWERS VERSUS
LIGHT RAIN/DRIZZLE IS GETTING INTO BETTER FOCUS AS UPSTREAM
OBSERVATIONS AND MODEL GUIDANCE SEEM FAIRLY CONSISTENT, WITH A
PLUME OF DEEPER MOISTURE AND AMIDST STEEPER 700-500 MILLIBAR
LAPSE RATES PRESENT EARLY THIS MORNING IN SOUTHEASTERN QUEBEC.
THIS ACTIVITY IS SLOWLY PIVOTING TOWARDS VERMONT, SUCH THAT
NORTHEASTERN VERMONT SHOULD SEE PERIODIC SOAKING RAIN BY MID-
MORNING. IT WILL GRADUALLY EXPAND SOUTH AND WEST THROUGH THE
DAY. HIGHEST PROBABILITIES OF RAIN GENERALLY ARE DURING THE MID-
AFTERNOON AND EVENING; LIKE YESTERDAY, COVERAGE OF LIGHT TO
MODERATE RAIN SHOWERS SHOULD BE WIDESPREAD REGARDLESS OF SMALL
DIFFERENCES IN POP ACROSS THE REGION. TEMPERATURES ALOFT WILL
REACH BEGIN TO CLIMB A BIT AFTER REACHING THEIR NADIR THIS
MORNING, ENOUGH SO THAT EVEN MOUNTAIN SUMMITS THAT HAVE SEEN
SOME SNOW OR RAIN/SNOW MIX WILL SWITCH OVER TO RAIN BY EVENING.
VALLEY TEMPERATURES WILL TOP OUT NEAR YESTERDAY'S HIGHS,
ALTHOUGH TIMING OF STEADIER RAIN IN NORTHERN NEW YORK ALONG WITH
A COOL START TO THE DAY FAVORS SLIGHTLY LOWER TEMPERATURES. IT
WILL ALSO BE A BIT BREEZIER THAN YESTERDAY WITH NORTHWESTERLY
FLOW IN PLACE, WHICH WILL ALSO PROVIDE MORE UPSLOPE GENERATED
LOW CLOUDS/FOG. EXPECT MISTY OR FOGGY CONDITIONS IN PATCHES THIS
EVENING INTO EARLY SUNDAY AS PRECIPITATION CHANCES DECREASE.
WITH LOW OVERCAST SUNDAY MORNING, IT WILL BE DAMP WITH TEMPERATURES
NOT TOO FAR OFF OF SATURDAY'S HIGHS. AS SUCH, WITH DAYTIME HEATING
AND THINNING CLOUDS, IT WILL WARM NOTICEABLY COMPARED TO THE LAST
FEW DAYS EVEN IF THE AIR MASS REMAINS CHILLY FOR THIS TIME OF YEAR.
LINGERING CYCLONIC FLOW AND DIURNALLY DRIVEN INSTABILITY WILL SPARK
ISOLATED TO SCATTERED SHOWERS, WITH GREATEST CHANCES OF RAIN IN THE
AFTERNOON OVER NORTHERN NEW YORK WHERE LOW/MID LEVEL LAPSE RATES
SHOULD BE STEEPEST. HIGHS WILL RANGE FROM THE MID 50S TO LOW 60S, OR
ABOUT 10 DEGREES WARMER THAN RECENT DAYS AND STILL 10 DEGREES BELOW
NORMAL.
SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/
AS OF 400 AM EDT SATURDAY...SUNDAY NIGHT AND MONDAY WILL
CONTINUE WITH A DRYING AND WARMING TREND AS SURFACE HIGH
PRESSURE RIDGES INTO THE NORTH COUNTRY. SURFACE HIGH WILL RIDGE
SOUTHWARD FROM CANADA, AND WE'LL FINALLY SEE SOME SUNSHINE IN
THIS PERIOD ALSO. FOG FORMATION IS LIKELY SUNDAY NIGHT AS WINDS
BECOME LIGHT TO CALM AND SKIES WILL BE CLEARING. MINIMUM
TEMPERATURES WILL DIP INTO THE 40S AREAWIDE. WITH CLEARING SKIES
AND WARMING TEMPERATURES, OUR MAXIMUM TEMPERATURES ON MONDAY
WILL FINALLY BE VERY CLOSE TO SEASONAL NORMALS AGAIN, RANGING
FROM THE LOW 60S TO LOW 70S.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
AS OF 400 AM EDT SATURDAY...MONDAY NIGHT THROUGH WEDNESDAY WILL
FEATURE MORE DRY WEATHER AND WARMING TEMPERATURES AS SURFACE
AND UPPER LEVEL RIDGES BUILD OVER THE AREA. TEMPERATURES WILL
RETURN TO SEASONAL NORMALS DURING THIS TIMEFRAME. CHANCES FOR
PRECIPITATION WILL RETURN ON THURSDAY AS AN UPPER LEVEL TROUGH
AND SHORTWAVE ENERGY PASSES OVERHEAD. UPPER LEVEL PATTERN
BECOMES PROGRESSIVE TOWARDS THE END OF THE WEEK AND THERE WILL
BE ADDITIONAL CHANCES FOR PRECIPITATION FOR FRIDAY AND INTO THE
WEEKEND.
AVIATION /14Z SATURDAY THROUGH WEDNESDAY/
THROUGH 12Z SUNDAY...VERY CHALLENGING AVIATION FORECAST
CONTINUES THIS MORNING AS CIGS BOUNCE BETWEEN IFR AND MVFR AT
MANY TAF SITES ALONG WITH LIGHT RAIN THROUGH THE PERIOD,
ALTHOUGH CHANCES OF RAIN WILL DIMINISH OVERNIGHT. HAVE
OFFERED MAINLY TEMPORARY IFR AS PREVAILING LOW CEILINGS ARE NOT
LIKELY. VISIBILITIES ARE ALSO TRICKY BUT GENERALLY 4SM OR
GREATER. LIGHT NORTH/NORTHWEST FLOW WILL CONTINUE WITH WINDS
MAINLY 4 TO 8 KNOTS, DIMINISHING SLIGHTLY AFTER 00Z.
