AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
152 PM EDT MON OCT 6 2025
SYNOPSIS
HIGH PRESSURE DOMINATES AND CONTINUES THE DRY WEATHER PATTERN WITH
WELL ABOVE NORMAL TEMPERATURES ACROSS THE REGION THROUGH
MONDAY. A PASSING COLD FRONT WILL BRING A BATCH OF RAIN AND
POSSIBLY A STORM LATE TUESDAY INTO EARLY WEDNESDAY, FOLLOWED BY
DRY AND COOLER WEATHER THROUGH SATURDAY.
NEAR TERM /THROUGH TUESDAY/
AN EXPANSIVE UPPER LEVEL RIDGE OF HIGH PRESSURE REMAINS FIRMLY
IN PLACE ALOFT, WITH FULL SUNSHINE. AT THE SURFACE, HIGH
PRESSURE CENTERED TO THE SOUTH AND EAST OF THE AREA HAS PLACED
OUR REGION IN LIGHT SOUTHWEST RETURN FLOW. WITH THE CLEAR SKY
AND VERY LIGHT WIND, WE ARE GETTING WIDE DIURNAL RANGES BETWEEN
COOL MORNINGS AND WARM AFTERNOONS WITH HIGHS AROUND 15 TO 20
DEGREES ABOVE AVERAGE TEMPERATURES FOR THIS TIME OF YEAR.
WITH WARM AIR ADVECTION CONTINUING, TEMPERATURES WILL NOT BE
QUITE AS COOL AS PRIOR NIGHTS. OVERNIGHT TEMPERATURES TONIGHT
ARE EXPECTED TO ONLY GO AS LOW AS INTO THE MID 50S TO LOW 60S.
SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/
HIGH PRESSURE BEGINS TO SLIDE EAST AND OUT TO SEA AS AN INCOMING
FRONTAL SYSTEM APPROACHES. A LARGE UPPER LEVEL TROUGH DRIVES THE
SYSTEM, WITH AN EMBEDDED WAVE HELPING TO PUSH THE FRONT ALONG
AND TOWARDS OUR AREA. DUE TO THIS SYSTEM BEING A LITTLE
UNORGANIZED, IT'LL LIKELY BE SLOWER IN NATURE. PWAT VALUES
INCREASE TO UP TO AN INCH AND A HALF WITH THIS FRONT, WITH
ACCUMULATING RAINFALL LIKELY SPANNING FROM TUESDAY MORNING
THROUGH WEDNESDAY AFTERNOON. WITH CURRENT DROUGHT CONDITIONS,
ANY HYDROLOGICAL ISSUES SUCH AS FLASH FLOODING IS NOT A CONCERN.
A FEW HUNDRED J/KG OF CAPE COULD BRING SOME EMBEDDED ORDINARY
STORMS AS THE FRONT PASSES THROUGH, MAINLY BETWEEN TUESDAY
AFTERNOON AND EVENING TIMEFRAME.
AFTER THE PASSAGE OF THE FRONT WITH THE MUCH-WELCOMED RAIN, THERE
WILL BE A SOLID 14-18 DEGREE DROP IN HIGHS WEDNESDAY. AFTER
UPPER 50S-MID 60S WEDNESDAY, COLD AIR ADVECTION WILL SEND
TEMPERATURES TO MAINLY 30S WEDNESDAY NIGHT WITH A MOSTLY CLEAR
SKY AND NORTH-NORTHWEST WIND. SOME OF THE HIGHEST TERRAIN AREA
COULD GET AROUND FREEZING, AND SHELTERED VALLEYS ALSO COULD GET
FROST.
LONG TERM /THURSDAY THROUGH SUNDAY/
BACK TO DRY WEATHER FOR THE REMAINDER OF THE WEEK, WITH COOLER
TEMPERATURES YET ALSO FAIRLY CLOSE TO CLIMATOLOGY.
A LARGE HIGH PRESSURE WILL MOVE DIRECTLY OVER THE REGION
THURSDAY-FRIDAY, AND STILL AT LEAST BE DOMINANT EVEN INTO THE
START OF THE WEEKEND. IDEAL RADIATIONAL COOLING SET UP IS LIKELY WITH
LIGHT-CALM WINDS AND CLEAR SKY THURSDAY NIGHT, AND THUS OUR
HIGHEST CHANCE FOR AREAS OF FROST WITH LOWS OF UPPER 20S-MID
30S; MORE LIKE UPPER 30S NEAR THE FINGER LAKES AND WYOMING
VALLEY. THIS OF COURSE IS NOT AT ALL UNUSUAL GIVEN THE TIME OF
YEAR. THAT WILL BE BOOKENDED BY MID 50S-LOWER 60S FOR HIGHS
THURSDAY, AND UPPER 50S-MID 60S ON FRIDAY.
MANY MEMBERS OF MODEL ENSEMBLES DEPICT AN UPPER LEVEL WAVE OR
EVEN LOW ATTEMPTING TO DIG INTO THE WESTERN GREAT LAKES
SATURDAY, YET SKEWING SOUTH WITH TIME. OUR AIR MASS LOOKS MORE
LIKELY TO REMAIN DRY WITH SURFACE HIGH PRESSURE HANGING ON.
THUS RAIN CHANCES ARE AROUND OR LESS THAN 10 PERCENT DURING HE
WEEKEND, AND THE NATIONAL BLEND OF MODELS IS AROUND CLIMATOLOGY
WITH HIGHS OF 60S-NEAR 70 AND LOWS OF MID 30S-LOWER 40S.
AVIATION /18Z MONDAY THROUGH SATURDAY/
CLEAR SKIES WITH WIDESPREAD VFR CONDITIONS WILL CONTINUE THE
REST OF THIS AFTERNOON, EVENING AND INTO THE OVERNIGHT HOURS.
THERE COULD BE SOME PATCHY FOG AFTER MIDNIGHT, INTO THE PREDAWN
HOURS TUESDAY AT ELM; BRINGING THE POSSIBILITY FOR INTERMITTENT
IFR OR LOWER RESTRICTIONS...MAINLY IN THE 07-11Z TIME FRAME
TUESDAY. THIS WILL BE A TRICKY FOG FORECAST, AS SKIES ARE LIKELY
TO REMAIN CLEAR BUT WINDS OFF THE SURFACE WILL CONTINUE OUT OF
THE SOUTH-SOUTHWEST UP TO 8-10 KTS.
MID AND HIGH LEVEL CLOUDS INCREASE LATE TONIGHT INTO TUESDAY
MORNING. EVENTUALLY MVFR CLOUD BASES AND CIGS WILL BE POSSIBLE
AT ELM, ITH AND BGM BY THE MID TO LATE MORNING HOURS TUESDAY AS
A SYSTEM MOVES IN, BRINGING LIGHT RAIN SHOWER CHANCES TOO.
LIGHT SOUTH WINDS UP TO 10 KTS WILL CONTINUE THROUGH SUNSET,
AND INTO THE OVERNIGHT...ALTHOUGH SOME OF THE DEEPER VALLEYS
COULD DECOUPLE WITH VARIABLE OR CALM WINDS. SOUTH-SOUTHWEST
WINDS CONTINUE ON TUESDAY 6-15 KTS.
