AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
644 AM EDT SUN SEP 14 2025
SYNOPSIS
A WEAK COLD FRONT APPROACHES FROM THE NORTH TODAY AND PASSES
THROUGH BY EARLY MONDAY. HIGH PRESSURE THEN RETURNS, EVENTUALLY
SETTLING EAST OF THE REGION TOWARDS THE MIDDLE OF THE WEEK. A
WEAK LOW TO THE SOUTH COULD IMPACT THE AREA WEDNESDAY INTO
THURSDAY. A COLD FRONT DRIFTING DOWN FROM THE NORTH ON FRIDAY
WILL PASS THROUGH FRIDAY NIGHT, AND REMAIN TO THE SOUTH ON
SATURDAY AS STRONG HIGH PRESSURE BUILDS IN ITS WAKE.
NEAR TERM /THROUGH TONIGHT/
THERE ARE PATCHES OF DENSE FOG ACROSS PARTS OF THE INTERIOR
THIS MORNING. EXPECTING THIS TO LAST UNTIL 9AM WITH SOME
DECREASE BETWEEN 8AM AND 9AM. WITH RAPID CHANGE IN VISIBILITIES,
HAVE SPS OUT TO ADDRESS THIS.
A WEAK COLD FRONT APPROACHES FROM THE NORTH TODAY INTO THIS
EVENING, BEFORE EVENTUALLY MAKING ITS WAY THROUGH BY EARLY
MONDAY. OTHERWISE, WEAKENING HIGH PRESSURE WILL BE IN PLACE.
WINDS WILL BE MORE SOUTHERLY TODAY AND THEN BECOME MORE VARIABLE
TONIGHT, EVENTUALLY SWITCHING TO MORE NORTHEASTERLY FLOW BY
EARLY MONDAY.
UPPER LEVEL TROUGH MOVES THROUGH NORTHEAST WITH COLDEST AIR
ALOFT AND LOWEST GEOPOTENTIAL HEIGHTS TOWARDS MORE EASTERN
SECTIONS OF THE FORECAST REGION.
CAMS DEPICT SHOWER DEVELOPMENT ONCE AGAIN AND MADE THE CHANCE
POPS FARTHER EAST ACROSS SOUTHEAST CONNECTICUT AND EASTERN LONG
ISLAND WITHIN THE AFTERNOON INTO EARLY EVENING. THIS IS CLOSER
TO THE APEX OF THE MID LEVEL TROUGH AND ASSOCIATED HIGHER
POSITIVE VORTICITY ADVECTION. FARTHER WEST, POPS LIMITED TO
SLIGHT CHANCE. MODEL BUFKIT SOUNDINGS CONVEY A PROMINENT MID
LEVEL CAP SO THAT IS EXPECTED TO LIMIT THE INSTABILITY AND
THEREFORE KEPT THE MENTION OF THUNDER OUT OF THE FORECAST.
NBM EXHIBITED A RECENT WARM BIAS FOR SOME LOCATIONS WITH MOS
CONSENSUS PERFORMING BETTER REGARDING HIGH TEMPERATURE FORECAST
FOR THE PREVIOUS DAY. TEMPERATURE FORECAST USED AN EQUAL BLEND
OF NBM AND MAV MOS AS WELL AS MET MOS. FORECAST HIGH
TEMPERATURE RANGE MAINLY FROM MID 70S TO LOWER 80S.
FOR TONIGHT, THE UPPER LEVEL TROUGH AXIS EXITS FARTHER SOUTHEAST
OF THE REGION. IN ITS PLACE ACROSS THE LOCAL REGION WILL BE AN
AREA OF NEGATIVE VORTICITY ADVECTION. INSTABILITY WILL LOWER AS
WELL WITH TEMPERATURES COOLING. THE WEAK COLD FRONT MOVES
THROUGH BUT WILL ESSENTIALLY DISSIPATE AS IT MOVES THROUGH.
THERE ARE SOME SLIGHT CHANCE POPS FOR EASTERN SECTIONS OF THE
REGION EARLY IN THE EVENING BUT OTHERWISE A MAINLY DRY NIGHT IS
EXPECTED.
FOLLOWED A COMBINATION OF THE NBM AND MOS CONSENSUS FOR LOWS
TONIGHT AS THERE WILL BE SOME RADIATIONAL COOLING. CLOUDS
DECREASE AND WINDS BECOME LIGHT AND VARIABLE, EVENTUALLY
SETTLING UPON A MORE NORTHEAST DIRECTION TOWARDS DAYBREAK
MONDAY. THE FORECAST LOWS TONIGHT RANGE FROM THE LOWER 50S TO
MID 60S.
IN ADDITION, A COMBINATION OF RADIATIVE AND ADVECTIVE FOG
FORMATION COULD OCCUR FOR SOME LOCATIONS LATE TONIGHT INTO EARLY
MONDAY MORNING. HAVE THIS IN THE FORECAST AS PATCHY FOG.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
UPPER LEVELS EXHIBIT THE LOCAL AREA IN BETWEEN A CUTOFF LOW
WELL TO THE SOUTH AND WEST AND A SUBTLE TROUGH TO THE NORTH AND
EAST. THE CUTOFF LOW STARTS TO APPROACH THE AREA TOWARDS
MIDWEEK. AT THE SURFACE, HIGH PRESSURE BUILDS IN FROM THE NORTH
MONDAY AND THEN SHIFTS OFFSHORE TO THE EAST ON TUESDAY.
THE MORE EASTERLY FLOW EACH DAY, MONDAY AND TUESDAY, WILL MAKE
FOR A COOLING TREND TO HIGH TEMPERATURES, ESPECIALLY ALONG THE
COAST WITH MORE MARITIME INFLUENCE. THE HIGH TEMPERATURES ARE
MAINLY IN THE MID 70S TO NEAR 80 MONDAY AND THEN LOWER TO UPPER
70S ON TUESDAY.
DRY CONDITIONS CONTINUE UNTIL TUESDAY NIGHT, WHEN CHANCE FOR
RAIN RETURNS FROM SOUTH TO NORTH AS A WEAK LOW APPROACHES FROM
OFFSHORE.
LOWS FORECAST AT NIGHT INTO EARLY MORNING ARE SIMILAR FOR LATE
MONDAY NIGHT INTO EARLY TUESDAY MORNING AND FOR LATE TUESDAY
NIGHT INTO EARLY WEDNESDAY MORNING. FOR LATE MONDAY NIGHT INTO
EARLY TUESDAY MORNING, SOME LOCATIONS COULD HAVE FOG DEVELOP
ONCE AGAIN.
