The episode as NWS ILN wrote it up.
A surge of cold air worked into the Ohio Valley with an upper level disturbance pivoting through the region on Sunday night, November 16th. This cold surge changed any rain that was in the area to snow overnight for areas west of the I-75 corridor. East of this line, the changeover to snow did not occur until Monday and there were significantly lower snowfall amounts recorded here.

ACROSS THE CWA)...A STRONG PUSH OF COLD ADVECTION WILL BEGIN. THIS
WILL HAVE AN IMPACT ON WEATHER CONDITIONS BEYOND JUST

GENERATE SOME WEAK INSTABILITY AT ABOUT 4000 FEET...THROUGH THE
HEART OF THE DENDRITIC GROWTH ZONE. THUS...FLURRIES (POSSIBLY EVEN
A SNOW SHOWER OR TWO) ARE QUITE LIKELY LATE MONDAY INTO MONDAY

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
MODELS ARE IN DECENT AGREEMENT WITH SYNOPTIC SYSTEMS TUESDAY NIGHT
INTO FRIDAY...THEN DIVERGE SOME THEREAFTER. HAVE USED A BLEND OF THE
ECMWF AND GFS FOR THE IMMEDIATE LONG TERM...THEN A BLEND OF THE
GFS/WPC GOING INTO THE WEEKEND.
FOR TUESDAY NIGHT...HIGH PRESSURE IS EXPECTED TO BUILD INTO THE SE
UNITED STATES. IT WILL BEGIN TO WARM AIR ADVECT ALOFT WHICH SHOULD
PUSH STRATOCUMULUS AND FLURRY THREAT TO THE EAST DURING THE EVENING.
MID AND HIGH LEVEL CLOUDS WILL THEN INCREASE FROM THE NORTHWEST IN
ADVANCE OF THE NEXT WEATHER SYSTEM. HAVE TAKEN A BLEND OF MODELS FOR
LOWS GIVEN THERE WILL STILL BE A PRESSURE GRADIENT AND CLOUDS FROM
TIME TO TIME. WILL FORECAST 10 TO 15 DEGREES WITH WIND CHILL VALUES
MOSTLY IN THE 0 TO -5 RANGE.
S/WV AND WEAK FRONT IS EXPECTED TO PASS THROUGH THE REGION WEDNESDAY
INTO WEDNESDAY NIGHT. SYSTEM IS FAIRLY MOISTURE STARVED AND HAVE
LIMITED LOW POPS/THREAT FOR LIGHT SNOW TO THE NRN ZONES. IT WILL BE
BLUSTERY ONCE AGAIN AS TEMPERATURES WARM INTO THE LOWER AND MID

FOR THURSDAY THROUGH FRIDAY...MODELS ARE SOMEWHAT DIFFERENT IN
REGARDS TO THE AMOUNT OF RESURGING ARCTIC AIR THAT WILL BLEED BACK
INTO OUR AREA IN ASSOCIATION WITH SFC HIGH PRESSURE. IT SHOULD BE
DRY...BUT TEMPERATURES WILL STILL BE WELL BELOW NORMAL.
MODELS KEEP ADVERTISING A PATTERN SHIFT FOR THE UPCOMING WEEKEND AS
THE LONGWAVE PATTERN WILL PUSH ARCTIC AIR BACK NORTH INTO CANADA
WHILE A SERIES OF WEATHER SYSTEMS MOVING INTO THE REGION WILL BE OF
A PACIFIC ORIGIN. THERE ARE SOME TIMING ISSUES BUT IT APPEARS THAT
RETURN FLOW/WAA PATTERN ALONG WITH A WEATHER SYSTEM WILL BRING AN
INCREASING THREAT FOR SHOWERS SATURDAY NIGHT INTO SUNDAY.
TEMPERATURES BY SUNDAY ARE FORECAST TO APPROACH NORMAL HIGHS IN THE
MID 40S TO AROUND 50 DEGREES.
&&
.AVIATION /03Z MONDAY THROUGH FRIDAY/...
PCPN FROM THE APPROACHING WINTER STORM HAS YET TO REALLY AFFECT
THE MAJORITY OF THE TAFS. THE ONE EXCEPTION IS KDAY WHEN THE IFR
SNOW HAS ALREADY STARTED. SRN TAFS HAVE SEEN THEIR CIGS ALREADY
FALL TO IFR WHILE THE CENTRAL OHIO TAFS ARE STILL MVFR.
SNOW SHOULD FILL IN ACROSS SRN INDIANA/NRN KENTUCKY AND LIFT UP
THE I-71 CORRIDOR. WORST CONDITIONS WILL OCCUR BETWEEN 06-12Z. AT
KCMH/KLCK THE PCPN SHOULD STAY RAIN LONGER...PAST 06Z...BEFORE
CHANGING TO SNOW. EXPECT IFR CONDITIONS FOR ALL THE TAFS AFT 06Z.
LATEST RUNS OF THE MODELS ARE A LITTLE SLOWER WITH THE BACK
EDGE...SO HELD ONTO LOWER CIGS AND VSBYS UNTIL 13-15Z. AS THE PCPN
ENDS...WINDS WILL SHIFT TO THE WEST AND INCREASE TO 10-15KT...WITH
GUSTS INTO THE 20S. CAA ALOFT ON THE AFTERNOON MAY LEAD TO SOME
SCATTERED SNOW SHOWERS REDUCING CONDITIONS TO MVFR.
OUTLOOK...MVFR/IFR CEILINGS AND VISIBILITIES WITH SCATTERED SNOW
SHOWERS ARE POSSIBLE MONDAY AFTERNOON/EVENING. SNOW SQUALLS AGAIN
ON TUESDAY COULD YIELD MVFR/IFR CONDITIONS AT TIMES.
