NATIONAL WEATHER SERVICE BINGHAMTON NY
806 PM EDT WED MAY 13 2026
WHAT HAS CHANGED
CHANCES OF PRECIPITATION WERE EXPANDED IN SPACIAL AND TEMPORAL
COVERAGE THURSDAY WITH THE WRAP AROUND PRECIPITATION. EARLY
NEXT WEEK HIGH TEMPERATURES WERE COORDINATED WITH WPC TO LOWER
THEM TO NOT HAVE WIDESPREAD 90S IN LOWER ELEVATIONS CONSIDERING
INCREASE IN POTENTIAL CLOUD COVER.
KEY MESSAGES
1) COLD FRONT FINISHES MOVING THROUGH THIS EVENING, ENDING THE
THREAT OF GUSTY THUNDERSTORMS. COOL WEATHER AND WRAP AROUND
PRECIPITATION CONTINUES THROUGH THURSDAY NIGHT.
2) WARM UP BEGINS THIS WEEKEND WITH A LARGE SCALE PATTERN SHIFT,
HIGH TEMPERATURES CLIMB INTO THE 80S AND PERHAPS A FEW AREAS TO
REACH THE 90S EARLY NEXT WEEK.
DISCUSSION
KEY MESSAGES 1...
THUNDERSTORMS DEVELOPED ALONG A COLD FRONT WITH SMALL HAIL, SOME
MEASURED GUSTS OF 40 TO 50 MPH, AND EVEN SPORADIC WIND DAMAGE
IN THE FINGER LAKES REGION SUGGESTIVE OF BORDERLINE SEVERE GUSTS
AROUND 60 MPH. HOWEVER, THE STORMS HAVE PROGRESSED INTO MORE
STABLE AIR, AND WELL AFTER DAYTIME HEATING, SO THEY WILL BE SUB-
SEVERE THE REST OF THIS EVENING WHILE TREKKING EAST OF
INTERSTATE 81. THEY WILL STILL GENERATE SOME LIGHTNING, AND
GUSTS OF 35 MPH WILL BE POSSIBLE IN THE STRONGEST REMAINING
CELLS.
ONCE THE FRONT IS THROUGH, A COASTAL LOW DEVELOPS NEAR SOUTHERN
NEW ENGLAND TONIGHT INTO THURSDAY. AS THIS LOW DEEPENS, WRAP
AROUND MOISTURE KEEPS CLOUDS AND RAIN SHOWERS AROUND TOMORROW
FOR MOST OF THE REGION. TERRAIN ENHANCEMENT IN THE CATSKILLS
COULD LEAD TO A FEW AREAS TO GET NEAR AN INCH OF RAIN THOUGH
MOST OF THE AREA WILL JUST SEE INTERMITTENT LIGHT RAIN SHOWERS.
CHANCES OF PRECIPITATION WERE EXPANDED THROUGH THE MORNING INTO
THE EARLY AFTERNOON TO COVER THIS WRAP AROUND PRECIP.
KEY MESSAGE 2...
THE LONG WAVE TROUGH THAT HAS BEEN PERSISTENT OVER THE LAST
SEVERAL WEEKS WILL BREAK DOWN THIS WEEKEND WITH FLOW BECOMING
MORE ZONAL AND EVEN SOME RIDGING BY THE END OF THE WEEKEND. 850
MB TEMPERATURES GO FROM AROUND FREEZING UP TO OVER 10C BY
SATURDAY NIGHT AND EVEN APPROACHING 20C MONDAY INTO TUESDAY.
HIGH TEMPERATURES IN THE 80S ARE LIKELY NEXT WEEK AND PERHAPS
SOME 90 DEGREE READINGS IN THE WYOMING VALLEY. RH FIELDS ALOFT
HAVE TRENDED A LITTLE MORE SATURATED SO CLOUDS ARE UNCERTAIN SO
DECIDED TO BACK OFF FROM ORIGINAL FORECAST HIGHS MONDAY AND
TUESDAY AND DROPPED THEM 3 TO 5 DEGREES FROM PREVIOUS FORECAST.
LOWER ELEVATIONS ARE ON THE DRIER SIDE SO DESPITE THE MUCH
WARMER TEMPERATURES, DEW POINTS REMAIN IN THE 50S TO LOW 60S
HELPING TO KEEP HEAT INDICES IN CHECK.
AVIATION /00Z THURSDAY THROUGH MONDAY/
THUNDERSTORMS PASSED THROUGH SEVERAL OF THE TERMINALS LATE THIS
AFTERNOON, AND AS OF 00Z IS STILL IMPACTING KAVP WITH AT LEAST
SHOWERS STILL HANGING AROUND KBGM. BEHIND THE FRONT, WIND WILL
TURN LIGHT AND VARIABLE OVERNIGHT. CLOUDS WILL HAVE SOME BREAKS
SO FOG AND LOW STRATUS DEVELOPMENT DETAILS ARE TRICKY. HOWEVER,
ENOUGH BREAKS ARE FIGURED ALONG WITH MOIST CONDITIONS FROM
RECENT RAINFALL TO CAUSE RESTRICTIVE VALLEY FOG AT KELM, AND
POST-FRONTAL CEILINGS SETTLING INTO MVFR TO FUEL ALTERNATE
REQUIRED LEVELS OVERNIGHT. WITH A CHILLY UPPER LOW WOBBLING OVER
THE REGION, MOISTURE WILL REMAIN STUCK WITH 1500-2500 FT
CEILINGS ACROSS THE NY TERMINALS, THOUGH KAVP IS MORE LIKELY TO
ACHIEVE LOW END VFR CEILING IN THE AFTERNOON. WINDS WILL REMAIN
LIGHT THOUGH PREDOMINANTLY FROM THE NORTHWEST THURSDAY.
OUTLOOK:
THURSDAY NIGHT...SCATTERED SHOWERS WITH OCCASIONAL RESTRICTIONS,
ESPECIALLY FOR THE NY TERMINALS.
FRIDAY...GRADUAL IMPROVEMENT BACK TO VFR BY THE AFTERNOON.
FRIDAY NIGHT THROUGH MONDAY...MAINLY VFR; SMALL CHANCE FOR AN
ISOLATED SHOWER OR THUNDERSTORM SATURDAY NIGHT INTO SUNDAY.
