AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
657 AM EST SUN NOV 16 2025
SYNOPSIS
A TROUGH WILL SETTLE OVER EASTERN GREAT LAKES THROUGH MONDAY AS
HIGH PRESSURE SLOWLY BUILDS IN FROM THE WEST. THE HIGH WILL MOVE
OVER THE AREA MONDAY NIGHT BEFORE EXITING TO THE EAST ON TUESDAY.
WEAK LOW PRESSURE WILL MOVE INTO THE OHIO VALLEY LATE TUESDAY
INTO WEDNESDAY WITH A STRONGER LOW PRESSURE SYSTEM LIFTING
NORTHEAST INTO THE REGION TOWARDS THE END OF THE WEEK.
NEAR TERM /THROUGH MONDAY/
LAKE EFFECT PRECIP WILL DEVELOP OVER NW PA THIS MORNING AND
CONTINUE THROUGH THE REMAINDER OF THE NEAR TERM PERIOD AS AN
UPPER TROUGH SETTLES OVER THE EASTERN GREAT LAKES. THE VAST
MAJORITY OF THE LAKE EFFECT PRECIP WILL BE CONFINED TO NW PA
SINCE QUITE A BIT OF DRY AIR WILL BE IN PLACE OVER NE OH. PRECIP
WILL LIKELY START OFF AS RAIN EARLY BEFORE TRANSITIONING TO A
RAIN/SNOW MIX AS 850MB TEMPS COOL TO -5C TO -6C AND SURFACE
TEMPS FALL TO THE MID TO UPPER 30S BY LATE MORNING. A TRANSITION
TO SNOW AT INLAND LOCATIONS WILL LIKELY OCCUR AT SOME POINT LATE
THIS MORNING INTO THIS AFTERNOON WITH MORE EFFICIENT SNOWFALL
RATES DEVELOPING AS 850MB DROP TO -7C TO -8C THIS EVENING. THERE
WILL MOST LIKELY BE A PRIMARY BAND THAT WILL DEVELOP AND BECOME
ENHANCED BY A LAKE HURON CONNECTION DURING THE DAY TODAY BEFORE
WAVERING SOMEWHERE NEAR THE NW PA/NY BORDER THROUGH MONDAY
MORNING. THE BAND WILL LIKELY WEAKEN AS IT SHIFTS INTO WESTERN
NEW YORK MONDAY AFTERNOON.
LOOKING AT FORECAST SOUNDINGS, THE SETUP FOR HEAVY SNOWFALL
RATES AND SEVERAL INCHES OF SNOW ACCUMULATION APPEARS TO BE
FAVORABLE WITH AMPLE FORCING, VERY LITTLE SHEAR, AND EQUILIBRIUM
LEVELS AS HIGH AS 10KFT ANTICIPATED TONIGHT INTO MONDAY
MORNING. THE HEAVIEST SNOWFALL RATES AND GREATEST IMPACTS WILL
LIKELY OCCUR LATE TONIGHT INTO THE PRE-DAWN HOURS MONDAY. THE
MAJORITY OF HIGH RES GUIDANCE PLACES A SWATH OF 6-8 INCHES OF
SNOW (AND LOCALIZED AMOUNTS AS HIGH AS 8-10 INCHES) OVER
LOCATIONS WHERE THE BAND OF SNOW PERSISTS, HOWEVER THERE IS
QUITE A BIT OF UNCERTAINTY IN WHERE THAT OCCURS. THE WESTERN
EDGE OF THE SNOWFALL GRADIENT WILL BE VERY TIGHT AND WILL MAKE
THE DIFFERENCE BETWEEN IMPACTFUL SNOW AMOUNTS AND VERY LITTLE
(IF ANY) SNOWFALL THROUGH MONDAY AFTERNOON. THERE'S POTENTIAL
FOR FETCH TO VARY JUST ENOUGH TO MAKE THE BAND SOMEWHAT
TRANSIENT, WHICH COULD RESULT IN MORE EVENLY DISTRIBUTED SNOW
AMOUNTS AND OVERALL LOWER IMPACTS AND THERE'S ALSO A CHANCE THAT
THE BAND COULD SHIFT EAST INTO WESTERN NEW YORK.
WITH ALL OF THAT BEING SAID, CONFIDENCE IN THE PLACEMENT OF THE
PRIMARY LAKE HURON ENHANCED BAND IS TOO LOW TO WARRANT THE
ISSUANCE OF A LAKE EFFECT SNOW WARNING, SO HAVE OPTED FOR A
WINTER WEATHER ADVISORY THAT IS IN EFFECT FOR INLAND ERIE COUNTY
AND CRAWFORD COUNTY FROM 15Z TODAY TO 18Z MONDAY. WILL CONTINUE
TO MONITOR THE PLACEMENT OF THE LAKE EFFECT BAND AND ADJUST THE
FORECAST AND POSSIBLY UPGRADE HEADLINES IF NEEDED. THE MAJORITY
OF THE IMPACTS WILL LIKELY OCCUR IN THE HIGHEST TERRAIN OF THE
EASTERN PORTIONS OF NW PA (INCLUDING CORRY AND WATTSBURG AND
POSSIBLY SPARTANSBURG AND UNION CITY).
IT WILL BE QUITE GUSTY ACROSS THE ENTIRE TODAY WITH WIND GUSTS
TO 30 TO 40 MPH ANTICIPATED ACROSS THE ENTIRE AREA LATER THIS
MORNING THROUGH THIS EVENING. WINDS MAY BRIEFLY GET CLOSE TO 45
MPH ALONG THE LAKESHORE OF NE OH/NW PA AND ACROSS THE HIGHER
TERRAIN OF NORTHERN OHIO DURING PEAK DIURNAL MIXING TODAY. HIGHS
TODAY AND MONDAY WILL LIKELY REACH THE UPPER 30S TO LOWER 40S
ACROSS THE SNOWBELT REGION WITH WARMER TEMPS IN THE MID 40S
ANTICIPATED TO THE WEST. TONIGHT'S LOWS WILL BE IN THE 20S AND
LOWER 30S.
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/
ANY LINGERING LAKE EFFECT PRECIP SHOULD LIFT INTO WESTERN NEW
YORK AND CONTINUE TO WEAKEN AS HIGH PRESSURE EXPANDS EAST ACROSS
THE REGION MONDAY NIGHT. HOWEVER, BY TUESDAY, WEAKENING LOW
PRESSURE WILL TRACK EAST INTO THE OHIO VALLEY AS AN UPPER TROUGH
DROPS SOUTHEAST ACROSS THE LOCAL AREA. ISENTROPIC LIFT AHEAD OF
THE LOW WILL USHER PRECIP INTO THE LOCAL AREA TUESDAY MORNING
OR AFTERNOON THROUGH TUESDAY EVENING. GENERALLY EXPECT RAIN AS
THE PRIMARY PRECIP TYPE, HOWEVER WET BULBING MAY RESULT IN A
BRIEF PERIOD OF SNOW OR A RAIN/SNOW MIX AT THE ONSET TUESDAY
MORNING. THE MAJORITY OF THE PRECIP WILL LIKELY EXIT TO THE EAST
TUESDAY NIGHT AND THERE WILL PROBABLY BE A PERIOD OF DRIER
WEATHER BEFORE A SHORTWAVE POSSIBLY LIFTS ADDITIONAL SHOWERS
INTO THE REGION WEDNESDAY NIGHT.
HIGH TEMPERATURES WILL LIKELY BE IN THE 40S ON TUESDAY WITH
HIGHS IN THE UPPER 40S AND LOWER 50S ANTICIPATED FOR WEDNESDAY.
OVERNIGHT LOWS WILL TREND WARMER DURING THE SHORT TERM PERIOD
WITH 20S AND LOWER 30S MONDAY NIGHT GIVING WAY TO MID 30S TO
LOWER 40S BY WEDNESDAY NIGHT.
LONG TERM /THURSDAY THROUGH SATURDAY/
UNSETTLED WEATHER WILL RETURN TO THE LOCAL AREA DURING THE LONG
TERM PERIOD AS LOW PRESSURE LIFTS NORTHEAST INTO THE REGION
THURSDAY AND FRIDAY. THERE'S STILL A LOT TO IRON OUT WITH THE
STRENGTH AND EXACT TRACK OF THE LOW, BUT RAIN WILL LIKELY MOVE
INTO THE REGION AS THE LOW'S WARM FRONT LIFTS INTO THE REGION
THURSDAY NIGHT AND CONTINUE AS THE COLD FRONT AND LOW MOVE
ACROSS THE GREAT LAKES LATE FRIDAY OR SATURDAY. THIS WILL LIKELY
BE A WARMER SYSTEM WITH ABOVE NORMAL TEMPERATURES LIKELY
THURSDAY, FRIDAY, AND POSSIBLY SATURDAY.
AVIATION /12Z SUNDAY THROUGH THURSDAY/
VFR WILL PREVAIL AT ALL OF THE OHIO TERMINALS OVER THE NEXT 24
TO 30 HOURS AS DRIER AIR WINS OUT. THE MAIN CONCERN WILL BE
STRONG NW WIND GUSTS IN THE WAKE OF THE RAPIDLY DEEPENING LOW
PRESSURE SYSTEM LIFTING THROUGH NEW ENGLAND THIS MORNING. NW
WINDS OF 10-15 KNOTS THIS MORNING WILL INCREASE TO 15-20 KNOTS
THIS AFTERNOON AND EVENING, AND GUSTS OF 20-25 KNOTS THIS
MORNING WILL INCREASE TO 30-35 KNOTS THIS AFTERNOON AND EVENING.
THE WINDS WILL BE STRONGEST NEAR THE LAKESHORE AFFECTING KCLE
AND KERI. WINDS WILL GRADUALLY DIMINISH TONIGHT. THE SECOND
CONCERN IS LAKE-EFFECT SNOW IMPACTING KERI AT TIMES LATER TODAY
THROUGH TONIGHT. A BAND OF SNOW IS EXPECTED TO SET UP THIS
AFTERNOON, WOBBLING SLIGHTLY WEST AND EAST THROUGH TONIGHT. THE
BAND WILL PROBABLY BE MOST PERSISTENT EAST OF THE KERI TERMINAL,
BUT IT SHOULD SWING FAR ENOUGH WEST AT TIMES TO BRING A FEW
HOURS OF PREVAILING SNOW TO KERI, ESPECIALLY TONIGHT. KEPT A
TEMPO GROUP FOR RAIN/SNOW SHOWERS AND BRIEF MVFR THIS AFTERNOON,
WITH A TRANSITION TO STEADIER SNOW THIS EVENING AND TONIGHT.
USED A PROB30 TO TRY AND HIGHLIGHT THE PERIODS OF HEAVIER SNOW
AND MVFR OR LOWER CONDITIONS TONIGHT AS THE BAND PERIODICALLY
SWINGS IN, BUT THERE WILL BE PLENTY OF VFR IN BETWEEN THE BAND.
OUTLOOK...SPORADIC NON-VFR FROM LAKE EFFECT CLOUDS AND
RAIN/SNOW MAY LINGER ACROSS FAR NORTHEAST OHIO AND NORTHWEST
PENNSYLVANIA INTO TUESDAY. NON-VFR POSSIBLE AREAWIDE IN LIGHT
RAIN AND/OR SNOW ON TUESDAY. NON-VFR LIKELY TO RETURN LATE
THURSDAY IN WIDESPREAD RAIN.
MARINE
DEEP LOW PRESSURE WILL LIFT INTO NEW ENGLAND THIS MORNING, WITH THE
TRAILING COLD FRONT PROGRESSING WELL EAST OF THE SOUTHERN GREAT
LAKES REGION IN ITS WAKE. THE FAIRLY TIGHT PRESSURE GRADIENT AND
STRONG COLD AIR ADVECTION OVER THE 8-9 C LAKE ERIE WATERS WILL ALLOW
FOR STRONG WINDS MIXING TO THE LAKE SURFACE. NW WINDS OF 20-30 KNOTS
WILL CONTINUE THROUGH TONIGHT, WITH THE CENTRAL AND EASTERN BASINS
NEARING GALE AT TIMES THIS AFTERNOON. HOWEVER, GIVEN THE LOW PULLING
AWAY QUICKLY AND STRONGEST WIND FIELDS CLOSER TO LAKE ONTARIO, STILL
THINK LAKE ERIE WILL STAY JUST BELOW GALE. NEVERTHELESS, THE NW
WINDS WILL BUILD WAVE HEIGHTS TO 9 TO 11 FEET IN THE CENTRAL AND
EASTERN BASINS TODAY AND TONIGHT, SO IT WILL BE VERY ROUGH
CONDITIONS. WINDS WILL GRADUALLY DIMINISH IN THE WESTERN BASIN LATE
TONIGHT THROUGH MONDAY AFTERNOON, SO SMALL CRAFT ADVISORIES ARE
STILL EXPECTED TO END AT 09Z MONDAY FROM MAUMEE BAY TO THE ISLANDS
AND 21Z MONDAY FROM THE ISLANDS TO AVON POINT. IT WILL TAKE INTO
MONDAY NIGHT FOR WINDS AND WAVES TO DROP BELOW SMALL CRAFT CRITERIA
FARTHER EAST FROM AVON POINT TO RIPLEY, NY.
A NICE BREAK IS EXPECTED FOR MIDWEEK AS HIGH PRESSURE TRIES TO
BRIEFLY SETTLE OVER THE GREAT LAKES BEFORE LOW PRESSURE POSSIBLY
APPROACHES FROM THE MISSISSIPPI VALLEY LATE IN THE WEEK. THIS WILL
YIELD LIGHT AND VARIABLE WINDS TUESDAY BECOMING E AT 5-10 KNOTS
WEDNESDAY, BUT E TO SE WINDS SHOULD START TO INCREASE TO 10-15 KNOTS
BY THURSDAY.
