NATIONAL WEATHER SERVICE BURLINGTON VT
640 AM EDT WED JUN 3 2026
WHAT HAS CHANGED
AS OF 157 AM EDT WEDNESDAY...
NO SIGNIFICANT CHANGES TO THE FORECAST.
KEY MESSAGES
AS OF 157 AM EDT WEDNESDAY...
1. DRY AND WARM WEATHER IS EXPECTED FROM TODAY THROUGH FRIDAY
AS SURFACE AND UPPER LEVEL RIDGES BUILD OVER THE REGION.
2. WARM AND SHOWERY CONDITIONS, POSSIBLY WITH THUNDERSTORMS,
FOR THE WEEKEND, WITH A RETURN TO DRY WEATHER INTO NEXT WEEK.
DISCUSSION
AS OF 157 AM EDT WEDNESDAY...
KEY MESSAGE 1: WARMING TEMPERATURES ARE EXPECTED OVER THE NEXT
FEW DAYS WITH MAXIMUM TEMPERATURES RANGING THROUGH THE 80S EACH
AFTERNOON. LARGE RIDGES OF SURFACE AND UPPER LEVEL HIGH PRESSURE
WILL BE OVER THE NORTHEASTERN CONUS. MINIMUM TEMPERATURES WILL
RANGE THROUGH THE 50S AND 60S EACH OVERNIGHT. THE HIGH WILL
START TO BREAK DOWN AND SLIDE SOUTHEASTWARD ON FRIDAY MAKING WAY
FOR APPROACHING LOW PRESSURE SYSTEM WHICH WILL BRING RAIN TO
OUR AREA OVER THE WEEKEND. DEWPOINTS WILL REMAIN PRETTY LOW
THROUGH THE PERIOD, THEREFORE COMFORTABLE HUMIDITY LEVELS AND WE
DON'T HAVE TO BE CONCERNED ABOUT HEAT RISK THIS TIME.
KEY MESSAGE 2: AN UPPER TROUGH IS PROGGED TO RIDE ALONG THE
NORTHERN PERIPHERY OF AN SOUTHWARD RETREATING UPPER RIDGE ACROSS
OUR REGION HEADING INTO THE WEEKEND, IS ASSOCIATION WITH AN
AREA OF CYCLONIC FLOW OVER THE GREAT LAKES SUNDAY. A SLOW MOVING
FRONTAL BOUNDARY WILL SLIDE SOUTH OVER THE COURSE OF THE
WEEKEND WITH PRECIPITATION CHANCES SATURDAY GREATEST OVER THE
INTERNATIONAL BORDER AND ST. LAWRENCE VALLEY, SHIFTING SOUTH
INTO THE REST OF THE REGION ON SUNDAY. DEPENDING ON CLOUD COVER
ASSOCIATED WITH THE FRONT, IN ADDITION TO HOW MUCH DAYTIME
HEATING OCCURS, SOME RUMBLES OF THUNDER ARE POSSIBLE BOTH
SATURDAY AND SUNDAY AFTERNOON, THOUGH OVERALL DYNAMIC GUIDANCE
DENOTES ONLY MARGINAL THUNDER POSSIBILITIES. MORE NOTABLY IS
THAT PRECIPITABLE WATER FORECAST IS CONSISTENTLY AROUND 1.5 TO
1.75 INCHES IN BOTH THE DETERMINISTIC, AI, AND ENSEMBLE MODELS.
AS A RESULT ANY SHOWERS COULD HAVE LOCALLY HEAVY RAIN ASSOCIATED
WITH THEM, IN ADDITION TO ANY POSSIBLE THUNDERSTORM ACTIVITY.
PRECIPITABLE WATER FORECASTS ACROSS THE ST. LAWRENCE VALLEY AND
EASTERN VERMONT ARE IN THE 90TH PERCENTILE SATURDAY AFTERNOON
INTO SUNDAY MORNING ON THE NAEFS. GIVEN THE EXTENT OF THE
DRYNESS LEADING UP TO THE RAIN THIS WEEKEND, DO NOT ANTICIPATE
MUCH CONCERN WITH REGARDS TO A FLOOD RISK, THOUGH SOME RIVER
RISES CAN BE EXPECTED ESPECIALLY IF A BASIN RECEIVES ANY
THUNDERSTORMS SATURDAY, FOLLOWED BY ADDITIONAL STEADIER LIGHT
RAIN SUNDAY.
TEMPERATURES THIS WEEKEND WILL COOL TO MORE SEASONABLE LEVELS
WITH HIGHS IN THE MID TO UPPER 70S TO NEAR 80, WITH COMFORTABLE
HUMIDITY LEVELS AS DEWPOINTS LOOK TO BE IN THE UPPER 40S TO LOW
50S. INTO EARLY NEXT WEEK, LARGE SCALE RIDGING LOOKS TO BUILD IN
FROM THE NORTHWEST WITH ENSEMBLES FAVORING A RETURN TO DRY AND
WARM CONDITIONS.
AVIATION /12Z WEDNESDAY THROUGH SUNDAY/
THROUGH 12Z THURSDAY...HIGH CONFIDENCE IN ALL TERMINAL VFR CONDITIONS
THROUGH THE ENTIRE TAF PERIOD. LIGHT NORTHWEST GRADIENT FLOW WILL
DEVELOP BETWEEN 12 AND 15Z THIS MORNING WITH WINDS 10 KNOTS OR LESS
EXPECTED THROUGH THE AFTERNOON. A LAKE BREEZE IS LIKELY TO
DEVELOP AT PBG THIS MORNING BEFORE TURNING TOWARDS MORE
PREVAILING NORTHWESTERLY BY THIS AFTERNOON. WINDS WILL TREND
CALM ONCE AGAIN BEYOND SUNSET THIS EVENING. MSS SHOULD SEE
PERSISTENT WEST TO SOUTHWEST FLOW INTO TONIGHT DUE TO SOME
SUBTLE CHANNELED FLOW. HIGH CLOUDS ABOVE 15000 FT AGL WILL
