AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
133 PM EDT SAT MAR 28 2026
WHAT HAS CHANGED
BOOSTED WINDS AND GUSTS TODAY AND LOWERED
DEWPOINTS THIS AFTERNOON. REMAINDER OF FORECAST IS VERY CLOSE TO THE
PREVIOUS OUTLOOK.
KEY MESSAGES
1) COLD TODAY WITH SCATTERED LAKE EFFECT FLURRIES DEVELOPING MAINLY
OVER CENTRAL NY. SUNDAY AND MONDAY WILL TREND MILDER WITH DRY
CONDITIONS IN PLACE AND HIGH PRESSURE OVERHEAD.
2) SHOWERS RETURN NEXT WEEK AS LOW PRESSURE SYSTEMS TRACK ACROSS THE
NORTHERN TIER STATES. A CHANCE OF THUNDERSTORMS ENTERS THE PICTURE
TUESDAY INTO WEDNESDAY, AND LOCALLY HEAVY RAIN IS POSSIBLE.
DISCUSSION
KEY MESSAGE 1...
A WEAK UPPER LEVEL TROUGH OF LOW PRESSURE WILL MOVE THROUGH THE
REGION TODAY, TRIGGERING SCATTERED FLURRIES AND SOME LAKE SNOW
SHOWERS LATER THIS MORNING INTO THE AFTERNOON HOURS. TEMPERATURES
ALOFT WILL DROP TO NEAR -15C AT 850 MB LEADING TO STEEPENING LAPSE
RATES AND SUFFICIENT INSTABILITY TO TRIGGER SOME LAKE PLUMES. THE
AIRMASS IS QUITE DRY ALREADY, BUT THESE OTHER FACTORS ALONG WITH
LAKE ONTARIO MOISTURE SHOULD BE SUFFICIENT FOR SCATTERED
PRECIPITATION. A SECOND UPPER WAVE WILL PIVOT THE FLOW MORE TO THE
WEST TONIGHT FOCUSING WHAT'S LEFT OF ANY LAKE SHOW OVER ONEIDA
COUNTY PRIOR TO DAYBREAK SUNDAY. SNOWFALL AMOUNTS WILL BE NEGLIGIBLE
IN MOST LOCATION WITH UP TO A HALF INCH POSSIBLE WITHIN THE
MOST PERSISTENT BANDS. TEMPERATURES WILL REACH THE 30S TODAY AND
THEN 40S TO LOWER 50S ON SUNDAY AFTERNOON. ANOTHER COLD NIGHT
IN BETWEEN WITH LOWS IN THE 20S.
KEY MESSAGE 2...
AS HIGH PRESSURE SLIDES TO THE EAST AND A MORE ZONAL UPPER LEVEL
FLOW DEVELOPS, MULTIPLE DISTURBANCES WILL LEAD TO THE CHANCE FOR
SHOWERS EARLY TO MID NEXT WEEK. WHILE THERE IS SOME UNCERTAINTY WITH
THE TIMING OF SHOWERS ON MONDAY, BUT THE CONSENSUS IS LEANING ON A
PRIMARILY DRY DAY, FOLLOWED BY DEVELOPING SHOWERS MONDAY NIGHT.
CONFIDENCE INCREASES TUESDAY AND WEDNESDAY FOR SHOWERS AS LOW
PRESSURE PASSES BY TO THE NORTH. MOST OF OUR AREA IS EXPECTED TO BE
DEEP INTO THE WARM SECTOR SOUTH OF A FRONT ON TUESDAY, FOLLOWED BY A
COLD FRONTAL PASSAGE ON WEDNESDAY. MODEL RH AND CLOUD SIMULATION
FIELDS SUGGESTS A DIRTY WARM SECTOR WHICH SHOULD LIMIT INSTABILITY.
GENERAL THUNDER SEEMS POSSIBLE, HOWEVER DEEP CONVECTION LOOKS TO
REMAIN OVER THE OHIO VALLEY WHERE THE PROBABILITY FOR CAPE > 500
J/KG IS HIGHEST. SSW FLOW WILL ADVECT DEEP MOISTURE FROM THE
GULF INTO THE FRONTAL SYSTEM APPROACHING FROM TUESDAY TO WEDNESDAY.
WILL NEED TO CLOSELY WATCH THE TRENDS IN PRECIPITATION AS HYDROLOGIC
ENSEMBLES DO SUGGEST A LOW CHANCE PROBABILITY (10-20%) FOR RIVER AND
STREAM FLOODING DURING THE LATTER HALF OF NEXT WEEK.
TEMPERATURES ARE EXPECTED TO TREND WARMER MONDAY THROUGH WEDNESDAY
THROUGH THE 50S AND 60S WITH THE LOWER 70S INDICATED IN THE 25TH TO
10TH PERCENTILES IN THE ENSEMBLE GUIDANCE. THE SPRING SEE-SAW
TO COOLER AIR TEMPERATURES IS EXPECTED TO FOLLOW THE FRONT LATER
IN THE WEEK.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
MAINLY VFR CONDITIONS ARE EXPECTED THIS AFTERNOON, ALTHOUGH
OCCASIONAL/BRIEF SNOW SHOWERS MAY RESULT IN BRIEF MVFR VISBY
RESTRICTIONS AT KRME, KITH, AND KBGM. IF A HEAVIER SNOW SHOWER
HAPPENS TO IMPACT ONE OF THOSE TERMINALS, VERY BRIEF IFR VISBY
RESTRICTIONS CANNOT BE RULED OUT, BUT CONFIDENCE IS TOO LOW TO
INCLUDE IN THE TAFS. ANY REMAINING SNOW SHOWERS LIKELY MOVE EAST
OF THOSE TERMINALS BY 20Z, WITH VFR CONDITIONS RETURNING FOR THE
REMAINDER OF THE PERIOD (AT LEAST THROUGH 18Z SUNDAY).
GUSTY NORTHWEST WINDS ARE EXPECTED THIS AFTERNOON (OCCASIONAL
GUSTS UP TO 25KTS POSSIBLE, BEFORE QUICKLY DIMINISHING THIS
EVENING. WINDS WILL SHIFT TO MORE SOUTHWESTERLY BY LATE
TONIGHT/EARLY SUNDAY MORNING AT LESS THAN 10KTS.
