AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
927 PM EST SUN NOV 2 2025
SYNOPSIS
HIGH PRESSURE SHIFTS FARTHER OUT TO SEA TONIGHT. WEAK LOW PRESSURE
THEN APPROACHES FROM THE SOUTH MONDAY AHEAD OF A FAST MOVING COLD
FRONT PASSAGE OCCURRING MONDAY NIGHT. HIGH PRESSURE RETURNS TUESDAY
INTO WEDNESDAY. A QUICK PASSING LOW MOVES THROUGH WEDNESDAY
NIGHT INTO THURSDAY FOLLOWED BY HIGH PRESSURE AGAIN FOR FRIDAY.
ANOTHER LOW MAY IMPACT THE AREA FRIDAY NIGHT INTO SATURDAY.
NEAR TERM /UNTIL 6 AM MONDAY MORNING/
LOWERED TEMPERATURES AS CALM WINDS AND GOOD RADIATIONAL COOLING
HAVE COMMENCED. FOR EXAMPLE, KMGJ IN ORANGE COUNTY DROPPED 13
DEGREES IN AN HOUR EARLIER TONIGHT AS WINDS SLACKED. LOCATIONS
ON EASTERN LONG ISLAND HAVE ALSO COOLED ALREADY INTO THE LOWER
40S. A CIRRUS DECK ADVECTING FROM THE SOUTHWEST ALONG WITH
INCREASING SOUTHERLY FLOW AND RISING DEWPOINTS SHOULD ACT TO
TEMPER THE COOLING A BIT OVER THE NEXT COUPLE OF HOURS. PREVIOUS
DISCUSSION FOLLOWS.
SURFACE AND UPPER RIDGES SHIFT FARTHER EAST OUT TO SEA TONIGHT.
LIGHT SOUTH TO SOUTHWEST WINDS FOR COASTAL AREAS, WITH MUCH OF
THE INLAND LOCATIONS DECOUPLING WITH WINDS GOING CALM. THE
AMOUNT OF RADIATIONAL COOLING AND POTENTIAL FROST FORMATION
COULD HOWEVER BE HAMPERED FOR A PERIOD TONIGHT BY A BROKEN DECK
OF CIRRUS PROGGED TO PASS THROUGH. WILL KEEP PATCHY FROST IN THE
FORECAST FOR SOME OF THE INTERIOR AS THERE COULD BE ENOUGH TIME
TOWARDS DAYBREAK FOR THE CLOUDS TO THIN OUT AND BE LESS OF A
MITIGATING FACTOR.
SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/
WEAK LOW PRESSURE EMERGES OFF THE CAROLINA COAST EARLY ON
MONDAY AND HEADS NE THROUGH THE DAY. AN INVERTED TROUGH EXTENDS
NORTH TOWARD THE FORECAST AREA, ACTING AS A FOCUS FOR MOISTURE
CONVERGENCE. MEANWHILE, UPPER TROUGHING EXTENDING SOUTH FROM
CANADA HELPS PUSH A COLD FRONT THROUGH THE GREAT LAKES REGION
WITH THE FRONT CROSSING THE LOCAL AREA IN THE EVENING. THERE
WILL BE A BRIEF PERIOD OF SUBSIDENCE CREATED BY THE TWO SYSTEMS.
SHOWERS WILL STILL BE POSSIBLE FROM LATE MORNING THROUGH EARLY
EVENING WITH LIFT FROM THEIR RESPECTIVE MID LEVEL SHORTWAVES
COMBINED WITH AN APPROACHING LEFT EXIT REGION OF A STRONG UPPER
JET STREAK FROM THE NORTHERN STREAM SYSTEM. MODELS CONTINUE WITH
THE TREND OF A WETTER SCENARIO, SO HAVE INTRODUCED LIKELY POPS
FOR EASTERN LI AN SE CT. HIGHEST OVERALL CHANCES OF RAIN WOULD
BE IN THE AFTERNOON TO EARLY EVENING.
HIGH PRESSURE THEN BUILDS IN FROM THE WEST WITH A STRONGER PRESSURE
GRADIENT OVER THE REGION. DRY AND TURNING BREEZY OVERNIGHT MONDAY
INTO TUESDAY WITH WNW GUSTS 20-30 MPH. WINDS DIMINISH TUESDAY NIGHT
WITH THE SURFACE RIDGE SHIFTING IN. NBM TEMPS WERE CLOSELY FOLLOWED
IN THE SHORT TERM. SEASONABLE TEMPS ARE IN THE FORECAST.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
A VERY PROGRESSIVE PATTERN SETS UP IN THE LONG TERM WITH A SERIES OF
HIGH AND LOW PRESSURE SYSTEMS PASSING THROUGH WEDNESDAY INTO NEXT
WEEKEND.
HIGH PRESSURE REMAINS OVER THE AREA ON WEDNESDAY MORNING WITH AN
AREA OF LOW PRESSURE DEVELOPING TO THE NW THAT SLIDES NORTH OF THE
AREA BY WEDNESDAY NIGHT. MUCH OF THE DAY WEDNESDAY IS EXPECTED TO BE
DRY WITH INCREASING CHANCES FOR SHOWERS TOWARD EVENING AND INTO
WEDNESDAY NIGHT.
THE LOW QUICKLY MOVES THROUGH BY THURSDAY MORNING WITH ANOTHER DAY
OF GUSTY NW FLOW EXPECTED AS HIGH PRESSURE BUILDS IN ONCE AGAIN FROM
THE WEST. HIGH PRESSURE SETTLES OVER THE AREA LATE THURSDAY NIGHT
AND INTO FRIDAY MORNING WITH ONCE AGAIN ANOTHER LOW PRESSURE SYSTEM
APPROACHING FROM THE GREAT LAKES REGION. THE LOW PUSHES A COLD FRONT
THROUGH THE AREA WITH A CHANCE OF SHOWERS FRIDAY NIGHT INTO
SATURDAY. ANOTHER PAIR OF SUCCESSIVE HIGH AND LOW PRESSURE SYSTEMS
MAY IMPACT THE AREA SATURDAY AND SUNDAY RESPECTIVELY.
REGARDING TEMPERATURES, HIGHS EACH DAY WEDNESDAY THROUGH SUNDAY WILL
BE FAIRLY SEASONABLE WITH TEMPERATURES GENERALLY IN THE UPPER 50S TO
POSSIBLY LOWER 60S. THE COOLEST DAYS WILL BE THURSDAY AND SUNDAY
WITH GUSTY NW FLOW ADVECTING IN COOLER AIR WHERE THE HIGHS ARE
EXPECTED TO BE IN THE LOWER TO MIDDLE 50S. LOWS FOLLOW A SIMILAR
PATTERN WITH TEMPERATURES EACH NIGHT BEING IN THE MID TO UPPER 30S
INLAND TO THE UPPER 40S ALONG THE COAST. THE EXCEPTION IS THURSDAY
NIGHT WHERE COOLER TEMPERATURES ACROSS THE AREA WILL MEAN LOWS IN
THE 30S FOR MUCH OF THE AREA, TO NEAR 40 ALONG THE COAST.
