AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
1026 PM EST WED NOV 27 2024
SYNOPSIS
A LOW MOVES NORTHEASTWARD ACROSS THE OHIO VALLEY TONIGHT AND TO
THE MID-ATLANTIC REGION BY THURSDAY EVENING. A COLD FRONT MOVES
SOUTHEAST ACROSS THE REGION ON FRIDAY WITH A SURFACE TROUGH
ESTABLISHING ITSELF ACROSS THE GREAT LAKES REGION THROUGH THE
WEEKEND AND EARLY NEXT WEEK.
NEAR TERM /THROUGH THURSDAY NIGHT/
10:00 PM UPDATE...
RAIN HAS SPREAD INTO PRETTY MUCH THE ENTIRE FORECAST AREA AT
THIS POINT. WHERE MODERATE RAIN IS FALLING, WET-BULBING HAS
ALREADY BROUGHT SURFACE TEMPERATURES DOWN TO THE 35 TO 37 DEGREE
TEMPERATURE RANGE AND WE'VE ALREADY RECEIVED SEVERAL MPINGS OF A
RAIN/SNOW MIX. WE'LL NEED AN ADDITIONAL DECREASE IN TEMPERATURE
BY ABOUT 2-3 DEGREES IN THESE AREAS FOR ANY APPRECIABLE SNOWFALL
ACCUMULATIONS, WHICH IS SOMETHING THAT WILL PROBABLY BE MOSTLY
LIKELY IN THE HIGHER TERRAIN. STILL ONLY LOOKING AT 0.5-1.5" OF
SNOWFALL THROUGH EARLY THURSDAY MORNING, WITH LIMITED TO NO
IMPACTS TO TRAVEL. ANY SNOW ACCUMULATIONS WILL PROBABLY MELT BY
THE LATE MORNING AS TEMPERATURES WARM UP.
PREVIOUS DISCUSSION...
CYCLONIC WSW'ERLY TO W'ERLY FLOW ALOFT RESIDES OVER OUR CWA THROUGH
TONIGHT AS A SHORTWAVE TROUGH ADVANCES FROM THE NORTHERN GREAT
PLAINS TO THE EASTERN GREAT LAKES AND UPPER OH VALLEY. AT THE
SURFACE, THE ATTENDANT LOW MOVES NE'WARD FROM THE SOUTH-CENTRAL
UNITED STATES TO THE MID-ATLANTIC REGION AND DEEPENS AMIDST MSLP
FALLS AND MID/UPPER-LEVEL DIVERGENCE AHEAD OF THE AFOREMENTIONED
SHORTWAVE TROUGH AXIS. A RIDGE WILL EXIT E'WARD BEFORE A TROUGH AXIS
EXTENDING FROM THE AFOREMENTIONED SURFACE LOW MOVES E'WARD ACROSS
OUR REGION THIS EVENING AND ESPECIALLY OVERNIGHT TONIGHT. THIS
SURFACE TROUGH AXIS IS ARGUABLY ASSOCIATED WITH AN EFFECTIVE
OCCLUDED FRONT. A COMBINATION OF WEAK LOW-LEVEL CAA BEHIND THE
EFFECTIVE OCCLUDED FRONT AND LIMITED NOCTURNAL COOLING WILL ALLOW
LOWS TO REACH MAINLY THE LOWER TO MID 30'S AROUND DAYBREAK
THANKSGIVING MORNING. MOIST ISENTROPIC ASCENT AHEAD OF THE SHORTWAVE
TROUGH AXIS AND LOW-LEVEL ATMOSPHERIC COLUMN MOISTENING VIA THE WET-
BULB EFFECT WITH ALLOW PRECIP TO OVERSPREAD OUR CWA GENERALLY FROM
SOUTHWEST TO NORTHEAST LATE THIS AFTERNOON THROUGH THE WEE HOURS OF
THANKSGIVING MORNING. AIR TEMPS AND WET-BULB TEMPS AT/NEAR THE
SURFACE WILL BE CRITICAL FOR PRECIP TYPE. PRECIP IS EXPECTED TO BE
RAIN, MIXING WITH WET SNOW AT TIMES, ROUGHLY NORTH OF I-90 IN NW PA
AND NORTH OF A LINE FROM ROUGHLY I-90 AT THE OH/PA BORDER TO THE
FINDLAY AREA SINCE ONSHORE FLOW FROM ~9C LAKE ERIE WILL DEVELOP
EVENTUALLY ALONG THE BACKSIDE OF THE SURFACE LOW. FARTHER SOUTH,
RAIN IS EXPECTED TO MIX WITH SNOW THIS EVENING AND WILL LIKELY
CHANGE TO WET SNOW OVERNIGHT TONIGHT AS GREATER PRECIP RATES RESULT
IN A GREATER WET-BULB EFFECT AND APPRECIABLE DYNAMIC COOLING
ACCOMPANIES THE ISENTROPIC ASCENT. THE SNOW IS EXPECTED TO BE STEADY
TO HEAVY AT TIMES AS MODERATE TO STRONG ISENTROPIC ASCENT IS
EXPECTED TO BE MAXIMIZED IN A CLOUDY DGZ AT LEAST 0.5 KM THICK AT
TIMES. WHERE RAIN CHANGES TO SNOW, SNOW ACCUMULATIONS ARE EXPECTED
TO BE MAINLY LESS THAN ONE INCH. HOWEVER, 1-3" OF SNOW ACCUMULATION
IS POSSIBLE ALONG THE CENTRAL HIGHLANDS IN THE MANSFIELD AREA AND
EXPECTED IN THE HIGHER TERRAIN OF INTERIOR NW PA. NOTE, A
SUFFICIENTLY-COLD/MOIST LOW/MID-LEVEL ATMOSPHERIC COLUMN, THE SEEDER-
FEEDER PROCESS, AND WEAK LAKE-INDUCED CAPE ARE EXPECTED TO ALLOW
PRECIP TO BECOME SLIGHTLY LAKE-ENHANCED OVER AND GENERALLY SOUTH OF
LAKE ERIE DURING THE PREDAWN HOURS OF THANKSGIVING MORNING.
THE SHORTWAVE TROUGH AXIS, PRECEDING RAIN AND/OR WET SNOW, AND
ATTENDANT SURFACE TROUGH EXIT E'WARD THANKSGIVING MORNING. BEHIND THE
SHORTWAVE TROUGH AXIS, 850 MB TEMPS ARE EXPECTED TO COOL FROM VALUES
NEAR -3C TO NEAR -7C THROUGH THE DAY AND CONTRIBUTE TO LAKE-ENHANCED
PRECIP TRANSITIONING TO PURE LAKE-EFFECT PRECIP AS LOW-LEVEL
MOISTURE REMAINS FAIRLY-ABUNDANT. HOWEVER, A LOWERING SUBSIDENCE
INVERSION ACCOMPANYING A NARROW RIDGE AT THE SURFACE AND ALOFT,
BUILDING FROM THE WESTERN GREAT LAKES, WILL LIMIT THE MAGNITUDE OF
LAKE-INDUCED CAPE AND PRECIP, RESPECTIVELY. AFTERNOON HIGHS ARE
EXPECTED TO REACH THE UPPER 30'S TO MID 40'S. AS MEAN LOW-LEVEL FLOW
BACKS STEADILY FROM N'ERLY TO WNW'ERLY, LAKE-ENHANCED/EFFECT SHOWERS
WILL SHIFT GENERALLY E'WARD ACROSS MUCH OF NORTHERN OH AND
EVENTUALLY BECOME FOCUSED IN/NEAR THE PRIMARY SNOWBELT OF NE OH AND
NW PA BY SUNSET. TOWARD SUNSET, LAKE-EFFECT SHOWERS ORIGINATING OVER
LAKE MICHIGAN MAY IMPACT PORTIONS OF NW PA. PRECIP WILL MAINLY FALL
AS RAIN, BUT WET SNOW MAY MIX-IN AT TIMES DURING THE EARLY EVENING.
ANY SNOW ACCUMULATIONS DURING DAYLIGHT HOURS ARE EXPECTED TO BE A
TRACE.
A WINTER STORM WATCH REMAINS IN EFFECT FROM 12 AM EST FRIDAY TO 7 AM
EST MONDAY, DECEMBER 2ND FOR LAKE AND ASHTABULA COUNTIES IN OH, AND
ERIE AND CRAWFORD COUNTIES IN PA. CONTINUED UNCERTAINTY REGARDING
MEAN LOW-LEVEL FLOW DIRECTION AND PLACEMENT OF LAKE-EFFECT SNOW
(LES) DURING MOST OF THIS UPCOMING WEEKEND PRECLUDED UPGRADING ANY
PART OF THE WATCH TO A LES WARNING. WILL LET THE EVENING AND
OVERNIGHT SHIFTS REEVALUATE, BUT CONFIDENCE CONTINUES TO INCREASE
THAT A SIGNIFICANT AND IMPACTFUL PERIOD OF LES WILL IMPACT MUCH OF
THE PRIMARY SNOWBELT BEGINNING OVERNIGHT THURSDAY NIGHT.
THE NARROW RIDGE AT THE SURFACE AND ALOFT EXITS E'WARD THURSDAY
EVENING AND WILL BE FOLLOWED BY A SHORTWAVE TROUGH AND ATTENDANT
SURFACE TROUGH OVERSPREADING OUR REGION FROM THE UPPER MIDWEST AND
VICINITY THROUGH THE OVERNIGHT. LOW-LEVEL CAA WILL CONTINUE AS 850
MB TEMPERATURES FALL FURTHER TO NEAR -9C OVER ~9C LAKE ERIE AND OUR
CWA. THIS CAA WILL CONTRIBUTE TO OVERNIGHT LOWS REACHING THE MID
20'S TO LOWER 30'S AROUND DAYBREAK FRIDAY. AHEAD OF THE SHORTWAVE
TROUGH AXIS, INCREASING LOW/MID-LEVEL MOISTURE AND A RISING CAPPING
INVERSION AMIDST MID/UPPER-LEVEL DIVERGENCE AND LARGE-SCALE ASCENT
WILL CONTRIBUTE TO AN INCREASE IN LAKE-INDUCED CAPE AND PRECIP
INTENSITY, RESPECTIVELY. CAA AT THE SURFACE AND ALOFT AND THE WET-
BULB EFFECT WILL ALLOW LAKE-EFFECT PRECIP TO CHANGE FROM A RAIN/SNOW
MIX TO ALL SNOW BY MIDNIGHT. SNOWFALL RATES ARE EXPECTED TO REACH 1-
2" AT TIMES COURTESY OF STRONG/MAXIMIZED ASCENT IN A CLOUDY DGZ
ABOUT 1 KM THICK DURING THE OVERNIGHT HOURS. 2-5" OF FRESH SNOW
ACCUMULATION IS EXPECTED IN THE HEAVIEST AND MOST-PERSISTENT LES BY
DAYBREAK FRIDAY MORNING.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
THE MAIN CONCERN FRIDAY THROUGH THE HOLIDAY WEEKEND WILL BE GROWING
POTENTIAL FOR A SIGNIFICANT LAKE-EFFECT SNOWSTORM, THE START OF
WHICH WILL BE A LONG DURATION EVENT AS UNSEASONABLY COLD AIR POURS
ACROSS NEAR RECORD WARM WATERS OF THE GREAT LAKES. THE SNOW WILL
OCCUR IN SEVERAL PERIODS DUE TO SHIFTS IN THE BOUNDARY LAYER WIND
FIELDS, AND TIMING THE HEAVIEST PERIODS OF SNOW IS THE BIGGEST
CHALLENGE.
STARTING OFF FRIDAY, THE AXIS OF THE MID/UPPER TROUGH WILL QUICKLY
DEEPEN ACROSS THE GREAT LAKES AS AN ASSOCIATED CLOSED MID-LEVEL LOW
TAKES UP RESIDENCE AROUND HUDSON BAY. THIS IS A CLASSIC PATTERN FOR
A PROLONGED PERIOD OF DEEP ARCTIC AIR AND CYCLONIC FLOW ACROSS THE
GREAT LAKES, AND THIS TIME WILL BE NO EXCEPTION AS THE CLOSED LOW
PINWHEELS AROUND HUDSON BAY THROUGH THE WEEKEND. THIS WILL MAINTAIN
AN OVERALL WESTERLY MEAN BOUNDARY LAYER FLOW, WITH SUBTLE VARIATIONS
DRIVEN BY SHORTWAVES PROGRESSING THROUGH THE CYCLONIC FLOW, AS WELL
AS THE LAKE AGGREGATE THERMAL TROUGH. ONE SUCH SHORTWAVE LOOKS TO
CROSS THE REGION FRIDAY MORNING. NAM BUFKIT SOUNDINGS SUGGEST
ENHANCED OMEGA (LIFT) THROUGH A DEEP, SATURATED DGZ AS THE SHORTWAVE
CROSSES FRIDAY MORNING, WITH VERY WELL-ALIGNED 270 DEGREE FLOW AND
INSTABILITY BECOMING EXTREME (800-900 J/KG) AS EQUILIBRIUM LEVELS
RISE TO 15-20 THOUSAND FEET. THIS IS AN EXTREMELY IMPRESSIVE
FORECAST SOUNDING AND SUGGESTS THE LIKELIHOOD OF AN INTENSE SINGLE
BAND NEAR THE I-90 CORRIDOR BETWEEN LAKE COUNTY AND ERIE, PA.
HOWEVER, PLACEMENT OF THE BAND IS UNCERTAIN. THE LATEST HREF
GUIDANCE HAS SEVERAL MEMBERS SHOWING THE BAND IMPACTING MOST OF LAKE
AND ASHTABULA COUNTIES THROUGH AT LEAST MIDDAY BEFORE JOGGING
NORTHWARD AS THE BOUNDARY LAYER FLOW SLOWLY BACKS, WHEREAS
OTHER GUIDANCE TAKES THE BAND OFFSHORE OF LAKE AND ASHTABULA
COUNTIES FASTER AND CONFINES THE WORST IMPACTS TO ERIE COUNTY,
PA. THERE CONTINUES TO BE A KNOWN SOUTHWARD BIAS IN MOST HI-RES
GUIDANCE EARLY IN THE SEASON GIVEN THE TENDENCY FOR THE LAKE
AGGREGATE TROUGH TO BACK THE FLOW 10-20 DEGREES FROM WHAT THE
GUIDANCE IS FORECASTING, SO WE ARE MOST CONFIDENT IN THE
FORECAST FOR ERIE COUNTY, PA. WITH THAT BEING SAID, THE SNOWFALL
RATES COULD REACH 3 INCHES PER HOUR IN SUCH A BAND WITH THUNDER
AND LIGHTNING, SO EVEN IF THE BAND MOVES NORTHWARD FASTER, IT
WILL STILL BE A ROUGH MORNING ALONG I-90 FROM LAKE COUNTY INTO
ERIE, PA.
FRIDAY AFTERNOON, FORECAST SOUNDINGS SUGGEST SOME SLIGHTLY DRIER AIR
AND SUBSIDENCE BEHIND THE MORNING SHORTWAVE. THIS COMBINED WITH SOME
SHEAR COULD WEAKEN THE BAND FOR A FEW HOURS, WITH INSTABILITY SNOW
SHOWERS DEVELOPING INLAND GIVEN THE LATE NOVEMBER SUN ANGLE BENEATH
THE COLD POOL ALOFT. INSTABLILTY AND EQUILIBRIUM LEVELS WILL
STILL BE OFF THE CHARTS FRIDAY AFTERNOON, BUT NOT SURE THE BAND
WILL BE AS INTENSE. NEVERTHELESS, THE MEAN FLOW STILL LOOKS
265-270, SO EXPECT LAKE-EFFECT SNOW TO CONTINUE NEAR THE I-90
CORRIDOR, BUT RATES MAY BE MORE MANAGEABLE. HOW FAR SOUTH THE
BAND WILL BE IS STILL UNCERTAIN, BUT BE PREPARED FOR SNOWY
TRAVEL ALONG THE I-90 CORRIDOR, ESPECIALLY IN ERIE COUNTY, PA.
FRIDAY NIGHT THROUGH SATURDAY NIGHT, CONFIDENCE IS INCREASING THAT
MOST OF THE SNOWBELT WILL GET A BREAK FROM THE BULK OF THE SNOW AS
THE BOUNDARY LAYER FLOW BACKS TO MORE OF A 250 DEGREE FLOW. THIS IS
IN RESPONSE TO A STRONGER SHORTWAVE APPROACHING FOR SUNDAY. MOISTURE
AND OMEGA LOOK TO IMPROVE FRIDAY NIGHT INTO SATURDAY AS INSTABILITY
REMAINS EXTREME, SO THE BAND WILL BE STRENGTHENING ONCE AGAIN AS IT
MOVES NORTHWARD. THIS COULD PLACE ADDITIONAL HEAVY SNOWFALL IN ERIE
COUNTY, PA, BUT THE BAND SHOULD BE ALMOST ENTIRELY OFFSHORE OF OHIO
BY FRIDAY NIGHT/SATURDAY MORNING. TRIED TO TIGHTEN UP THE GRADIENT
OF POPS TO REFLECT THIS THINKING. BY SATURDAY AFTERNOON INTO
SATURDAY NIGHT, THE BAND MAY EVEN BE ENTIRELY OFFSHORE OF ERIE
COUNTY, PA. KEPT HIGH POPS ALONG THE ERIE LAKESHORE THROUGH SATURDAY
NIGHT GIVEN THE UNCERTAINTY, BUT WOULD NOT BE SURPRISED TO SEE THESE
LOWERED.
GIVEN THE ABOVE DESCRIBED UNCERTAINTY WITH HOW QUICKLY THE
BANDS MOVE NORTHWARD, KEPT THE WINTER STORM WATCH HEADLINES AS
IS AND WILL WAIT ONE MORE CYCLE TO TRY AND BETTER PINPOINT THE
MOVEMENT BEFORE MAKING WARNING DECISIONS. THERE WILL ALMOST
CERTAINLY BE WARNINGS WITH CONFIDENCE ON IMPACTS BEING HIGH, BUT
NEED TO BETTER DEFINE THE TIME WINDOWS AND EXACT LOCATIONS.
ERIE, COUNTY PA WILL DEFINITELY SEE THE SNOW THE LONGEST AND
THEREFORE THE HIGHEST AMOUNTS. WOULD NOT BE SURPRISED TO SEE
SOME TOTALS OF AROUND 2 FEET IN NORTHERN ERIE COUNTY BY SATURDAY
NIGHT, BUT SNOW TOTALS FARTHER WEST INTO NORTHERN ASHTABULA AND
LAKE COUNTIES REMAIN MORE UNCERTAIN DUE TO MOVEMENT OF THE
BAND. PLEASE FOCUS ON IMPACTS RATHER THAN SPECIFIC AMOUNTS.
THIS WILL BE THE START OF AN EXTENDED PERIOD OF BELOW NORMAL
TEMPERATURES, WITH HIGHS IN THE LOW 30S FRIDAY AND UPPER 20S/LOW 30S
SATURDAY. LOWS WILL BE IN THE TEENS BOTH FRIDAY AND SATURDAY
NIGHTS.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
LAKE-EFFECT SNOW WILL CONTINUE SUNDAY THROUGH MID-WEEK AS THE COLD
CYCLONIC FLOW PATTERN PERSISTS. A STRONG SHORTWAVE WILL DROP ACROSS
THE REGION SUNDAY BRINGING A REINFORCING SHOT OF ARCTIC AIR AS 850
MB TEMPS FALL TO AN AVERAGE OF -12 C THROUGH EARLY NEXT WEEK. THE
ASSOCIATED SURFACE TROUGH WILL PUSH THE BAND BACK ONSHORE SUNDAY AS
MORE OF A WNW FLOW DEVELOPS BEHIND IT. TIMING OF THE SHIFT IS
UNCERTAIN THIS MANY DAYS OUT, BUT A BURST OF SNOW IS EXPECTED IN
MOST OF THE SNOWBELT SUNDAY, INCLUDING THE CLEVELAND AREA AND PARTS
OF THE SECONDARY SNOWBELT, SO HAVE ELEVATED POPS. THE WNW FLOW IN
ITS WAKE, CONTINUED SYNOPTIC MOISTURE IN THE CYCLONIC FLOW, AND
SUBTLE SHORTWAVE DISTURBANCES COMBINED WITH CONTINUED MODERATE TO
EXTREME INSTABILITY WILL KEEP LAKE-EFFECT SNOWS GOING SUNDAY NIGHT
THROUGH AT LEAST TUESDAY. THIS COULD BRING SIGNIFICANT AMOUNTS TO
MUCH OF THE PRIMARY SNOWBELT, WITH THE SECONDARY SNOWBELT GETTING IN
ON THE ACTION AT TIMES TOO. HIGH PRESSURE DROPPING TOWARD THE OHIO
VALLEY WILL TRY TO TAPER THE SNOW SHOWERS BY WEDNESDAY, BUT
CONTINUED WNW FLOW AND FEED OF COLD AIR WILL LIKELY KEEP AT LEAST
WEAKER SNOW SHOWERS GOING. THE PERIOD FROM SUNDAY THROUGH EARLY/MID
NEXT WEEK WILL LIKELY NEED ADDITIONAL WINTER WEATHER HEADLINES.
TEMPERATURES WILL REMAIN BELOW NORMAL, WITH HIGHS IN THE UPPER
20S/LOW 30S SUNDAY THROUGH TUESDAY, MODERATING SLIGHTLY INTO THE
LOW/MID 30S WEDNESDAY.
AVIATION /00Z THURSDAY THROUGH MONDAY/
PRECIPITATION HAS OVERSPREAD MUCH OF THE AREA, CURRENTLY FALLING
AS MOSTLY RAIN, THOUGH THERE HAVE BEEN A FEW REPORTS OF SNOW
STARTING TO MIX IN. CONDITIONS SHOULD QUICKLY DROP TO MVFR AND
THEN TO IFR/LIFR WITH BOTH CEILINGS AND VISIBILITY. CEILINGS
COULD POTENTIALLY DROP TO AS LOW AS 200-300 FT AT TIMES. SHOULD
SEE A TRANSITION TO SNOW FOR PARTS OF THE AREA, ESPECIALLY TAF
SITES SUCH AS KMFD, KCAK, AND KYNG. VISIBILITY IN THE 1-3 SM
RANGE EXPECTED WITH RAIN, AND AS LOW AS 1/2 SM WHEREVER SNOW
DEVELOPS. SNOW ACCUMULATIONS AT TAF SITES SHOULD BE AN INCH OR
LESS.
PRECIPITATION GRADUALLY DISSIPATES FROM WEST TO EAST ON
THURSDAY, WITH CONDITIONS IMPROVING TO MVFR (AND POTENTIALLY
VFR FOR WESTERN TAF SITES). ANY SNOW THAT DEVELOPED SHOULD
TRANSITION BACK TO RAIN DURING THE DAYTIME HOURS. LAKE EFFECT
RAIN SHOWERS MAY DEVELOP IN PARTS OF NORTHEAST OHIO AND
NORTHWEST PENNSYLVANIA THURSDAY AFTERNOON. THESE RAIN SHOWERS
WILL BECOME SNOW SHOWERS AFTER 00Z/FRI.
OUTLOOK...NON-VFR LIKELY IN PERIODIC LAKE-EFFECT SNOW IS
EXPECTED THURSDAY NIGHT THROUGH MONDAY. THE HEAVIEST AND MOST-
PERSISTENT LAKE-EFFECT SNOW IN OUR REGION IS EXPECTED TO IMPACT
THE PRIMARY SNOWBELT IN FAR NORTHEAST OHIO AND NORTHWEST
PENNSYLVANIA.
MARINE
N WINDS WILL DEVELOP LATE TONIGHT AND THURSDAY AS LOW PRESSURE
DEVELOPS OVER THE OHIO VALLEY AND MOVES EAST, TRENDING MORE NW
BY LATE THURSDAY. SPEEDS WILL STAY IN THE 10-20 KNOT RANGE UNTIL
THURSDAY NIGHT AND FRIDAY WHEN STRONG COLD AIR ADVECTION BRINGS
20-30 KNOTS WINDS AS THE DIRECTION BACKS MORE TO THE W. W WINDS
OF 20-30 KNOTS WILL THEN CONTINUE THROUGH SUNDAY, SO A LONG
PERIOD OF SMALL CRAFT HEADLINES IS POSSIBLE. WINDS TURN WNW AND
DECREASE SLIGHTLY TO 15-25 KNOTS SUNDAY NIGHT THROUGH TUESDAY,
SO HEADLINES WILL CONTINUE.
