A surface low tracked east of the Appalachians during the afternoon of November 26th. At the same time, a mid-level trough crossed the great lakes and helped squeeze out rain and snow showers over portions of the Ohio Valley, which quickly changed to snow showers in the evening.

The episode as NWS ILN wrote it up.
A surface low tracked east of the Appalachians during the afternoon of November 26th. At the same time, a mid-level trough crossed the great lakes and helped squeeze out rain and snow showers over portions of the Ohio Valley, which quickly changed to snow showers in the evening. Accumulations southeast of the I-71 corridor were generally 1 to 3 inches, with some higher amounts.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
408 PM EST TUE NOV 26 2013
.SYNOPSIS...
A STRONG EAST COAST STORM WILL BRING SNOW TO PARTS OF THE OHIO
VALLEY TONIGHT...WITH ADDITIONAL LIGHT SNOW SHOWERS POSSIBLE ON
WEDNESDAY. HIGH PRESSURE WILL BRING DRY CONDITIONS FOR THE REST OF
THE WEEK...WITH TEMPERATURES WARMING SLIGHTLY OVER THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A SIGNIFICANT EAST COAST STORM IS BEGINNING TO TAKE SHAPE...WITH
THE ILN CWA ON ITS FAR NORTHWESTERN PERIPHERY. SURFACE LOW
PRESSURE IS FORECAST TO TRACK EAST OF THE APPALACHIANS...WITH A
MID-LEVEL TROUGH CROSSING THE GREAT LAKES. SOME CHANGES WERE
REQUIRED TO THE SNOWFALL FORECAST THIS AFTERNOON...WITH THE OHIO
VALLEY FACING SOME OF THE CHALLENGES TYPICAL TO BEING ON THE EDGE
OF THE HEAVY PRECIPITATION.
PRECIPITATION TYPE WAS NOT A PARTICULAR PROBLEM TODAY. SNOW IS
ALREADY THE DOMINANT P-TYPE IN THE NORTHERN CWA...AND RAIN IS
OCCURRING IN THE SOUTHEAST. A MIX OF RAIN AND SNOW SHOULD CHANGE
TO ALL SNOW OVER THE NEXT HOUR OR TWO ELSEWHERE...WITH THE
SOUTHEAST CHANGING TO ALL SNOW A LITTLE LATER THIS EVENING. THE
ONLY PARTIAL CHALLENGE WAS WITH REGARDS TO SLEET...AS THERE HAVE
BEEN A FEW OBSERVATIONS (AT NWS ILN...VIA SFC OBS AND MPING
REPORTS). MODEL SOUNDINGS INDICATED A WARM LAYER NEAR 800MB...AND
ALTHOUGH THE MODELS ONLY BROUGHT THIS TO NEAR OR SLIGHTLY BELOW
FREEZING...WHAT HAS BEEN OBSERVED WOULD CERTAINLY SUPPORT A
PARTIAL MELTING OF THE HYDROMETEOR. FURTHER BELOW...NEAR
900MB...TEMPERATURES GO WELL BELOW FREEZING AGAIN. OVERLAYING THE
TEMP DIFFERENCES AT THESE TWO LEVELS HELPED DETERMINE WHERE SOME
SLEET MAY MIX IN WITH THE RAIN AND SNOW...GENERALLY ACROSS THE
SOUTHERN HALF OF THE CWA AND TRANSITIONING FROM WEST TO EAST OVER
THE NEXT SEVERAL HOURS.
MODEL QPF OUTPUT HAS UNMISTAKABLY COME IN LOWER WITH THE 12Z
RUNS. FOR THE WESTERN CWA...THE HAND BEING DEALT ON RADAR MAY WELL
BE THE DOMINANT FEATURE FOR THE EVENING. EVEN IN THE EASTERN
CWA...PRECIPITATION IS NOT EXPECTED TO LAST ALL THE WAY THROUGH TO
SUNRISE...ALTHOUGH ANOTHER ONE OR TWO WAVES (PERHAPS WITH A LITTLE
BIT OF MODERATE TO HEAVY SNOW) WILL OCCUR TONIGHT. FRONTOGENETIC
FORCING IS NOT ESPECIALLY STRONG IN THE LOWER LEVELS...WITH A
BETTER SIGNAL FURTHER ALOFT (ABOVE 700MB).
WITH THIS COMBINATION OF FACTORS (FORCING NOT OVERLY
STRONG...PRECIPITATION ENDING EARLY IN THE OVERNIGHT...RAIN AND
SLEET MIXING THIS EVENING)...A FORECAST FOR LOWERED SNOW TOTALS
WAS INEVITABLE. THIS REQUIRED ADJUSTMENTS TO THE HEADLINE
PACKAGE...AS A FEW OF THE SOUTHWEST CWA ADVISORY COUNTIES NO
LONGER APPEARED LIKELY TO REACH THE 2-INCH CRITERIA...AND A FEW OF
THE NORTHEAST CWA WARNING COUNTIES NO LONGER APPEARED LIKELY TO
REACH THE 6-INCH CRITERIA. BY NUMBERS ALONE...EVEN THE CURRENT
HEADLINE PACKAGE MAY BE SLIGHTLY GENEROUS...BUT THERE IS ENOUGH
FORECAST UNCERTAINTY TO LEAVE SOME OF THESE COUNTIES IN THE
WARNING/ADVISORY PRODUCTS WITH THE AFTERNOON ISSUANCE. AT ANY
RATE...IT DOES APPEAR LIKELY THAT SOME OF THE COUNTIES WILL BE
ABLE TO BE CLEARED BEFORE THE 9 AM EXPIRATION TIME ON THE
HEADLINES.
THE MIN TEMPERATURE GRID WAS NOT CHANGED MUCH FROM THE PREVIOUS
FORECAST...BUT WITH COLD ADVECTION BEGINNING IN EARNEST...SOME
MINOR DOWNWARD ADJUSTMENTS WERE MADE.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
NORTHWEST FLOW ON WEDNESDAY WILL CONTINUE TO BRING IN COLDER
AIR...WITH RH PUSHING SOUTH FROM THE GREAT LAKES. QPF RESPONSE ON
THE LARGER-SCALE MODELS IS NOT OVERLY IMPRESSIVE...BUT THE SPC-WRF
AGREES WITH AN ANALYSIS OF SOUNDINGS AND PATTERN
RECOGNITION...LEADING TO THE BELIEF THAT ISOLATED TO SCATTERED
SNOW SHOWERS WILL BE POSSIBLE. A SLIGHT CHANCE POP HAS BEEN INSERTED
CWA-WIDE...WITH SLIGHTLY HIGHER VALUES IN THE FAR WESTERN CWA
(POTENTIALLY THANKS TO INFLUENCE FROM THE FETCH OFF LAKE
MICHIGAN).
AS HIGH PRESSURE MOVES CLOSE TO THE AREA...AND SKIES CLEAR
UP...WEDNESDAY NIGHT APPEARS TO BE FAVORABLE FOR SOME VERY COLD
TEMPERATURES. THIS WILL ESPECIALLY BE TRUE IF SOME AREAS ARE ABLE
TO MAINTAIN SNOW PACK (EAST AND SOUTHEAST CWA) FROM THE TUESDAY
NIGHT EVENT.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
AN UPPER LEVEL DISTURBANCE WILL BE NORTH OF THE FA ON THURSDAY.
THIS WILL ALLOW FOR AN INCREASE IN CLOUD COVER ESPECIALLY ACROSS
NORTHERN LOCATIONS. DUE TO THE DISTURBANCE STAYING NORTH OF THE
AREA HOWEVER NOT EXPECTING ANYTHING IN THE WAY OF PRECIPITATION.
HIGH PRESSURE WILL KEEP DRY CONDITIONS ACROSS THE AREA FOR FRIDAY
INTO SATURDAY. A WEAK DISTURBANCE WILL MOVE ACROSS THE REGION
SUNDAY INTO MONDAY. A MIX OF LIGHT RAIN AND SNOW SHOWERS WILL BE
POSSIBLE WITH THIS SYSTEM. HIGH PRESSURE AND DRY CONDITIONS WILL
RETURN TO THE REGION BY TUESDAY. TEMPERATURES WILL GRADUALLY WARM
THROUGH THE LONG TERM TIME PERIOD.
&&
.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
A MID LEVEL TROUGH WILL DIG SOUTHEAST ACROSS THE GREAT LAKES
TONIGHT INTO WEDNESDAY. MEANWHILE...AN EMBEDDED WEATHER DISTURBANCE
ALONG THE GULF COAST WILL PUSH NORTHEAST AND MERGE/PHASE WITH THE
MID LEVEL TROUGH...PRODUCING COASTAL CYCLOGENESIS ALONG THE EASTERN
SEABOARD. THIS PROCESS WILL BRING SOME SNOW TO THE TAF SITES THIS
AFTERNOON INTO THIS EVENING. AT THIS TIME...THE SNOW SHOULD REMAIN
LIGHT AT THE TERMINALS...BUT WILL RESULT IN MOSTLY IFR CONDITIONS
ALONG WITH SOME SITES FALLING BELOW ALTERNATE MINIMUM THRESHOLDS.
LARGE SCALE ASCENT SHIFTS TO THE EAST OVERNIGHT...WHICH WILL ALLOW
SNOW TO TAPER OFF FROM WEST TO EAST. ON WEDNESDAY...MID LEVEL
TROUGH WILL TRAVERSE THE GREAT LAKES AND OHIO VALLEY. COLD AIR
MOVING ACROSS THE WARMER WATER OF THE GREAT LAKES WILL RESULT IN A
FEW FLURRIES/ISOLATED LAKE EFFECT SNOW SHOWERS OVER THE REGION.
AVIATORS WILL LIKELY SEE IMPROVEMENTS TO MVFR CIGS AND VFR VSBYS
OVERNIGHT...WITH FLURRIES/SNOW SHOWERS SMALL ENOUGH IN COVERAGE AS
TO NOT PLACE THEM IN THE TAFS AT THIS TIME. WINDS WILL INCREASE
FROM THE NORTH/NORTHWEST THROUGH THE PERIOD AS LOW PRESSURE TO OUR
EAST DEEPENS...ALLOWING THE PRESSURE GRADIENT TO TIGHTEN. GUSTS
AROUND 25 KNOTS WILL BE POSSIBLE.
SURFACE HIGH PRESSURE IS FORECAST TO BUILD INTO THE OHIO VALLEY
WEDNESDAY NIGHT...ALLOWING WINDS TO SUBSIDE AND CONDITIONS TO IMPROVE
TO VFR.
OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED.
