What happened

The episode as NWS ILN wrote it up.

A warm front passed over the Ohio Valley. Due to a very cold ground, the rain showers in the wake of this warm front created a slushy layer of ice on road surfaces. While temperature sensors climbed above freezing in most locations, the rain still froze on area roadways. Numerous accidents and road closures were the result of this wintery weather.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wilmington, OH wrote its last area forecast discussion before the first event at Nov 22, 12:49 AM EST, 3 hours 11 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
1249 AM EST SAT NOV 22 2014

.SYNOPSIS...
A WEAK UPPER LEVEL DISTURBANCE WILL PUSH EAST ACROSS THE AREA LATE
TONIGHT INTO SATURDAY MORNING...BRINGING THE CHANCE FOR SOME LIGHT
RAIN AND FREEZING RAIN. A DEVELOPING LOW PRESSURE SYSTEM OVER THE
SOUTHERN PLAINS WILL LIFT INTO THE GREAT LAKES REGION SATURDAY NIGHT
INTO SUNDAY NIGHT. INCREASING SOUTHERLY WINDS AHEAD OF THIS WILL
LEAD TO A WARMING TREND FOR THE OHIO VALLEY THROUGH THE WEEKEND
ALONG WITH AN INCREASING CHANCE OF SHOWERS.

&&

.NEAR TERM /THROUGH TODAY/...
CLEAR SKIES THIS EVENING HAVE ALLOWED FOR TEMPERATURES TO DROP
OFF FAIRLY QUICKLY AFTER SUNSET. HAVE ADJUSTED TEMPS DOWN BUT
EXPECT WARM ADVECTION TO START AFTER MIDNIGHT. LOW LEVEL
SOUTHERLY FLOW WILL BE ON THE INCREASE LATER TONIGHT AS THE HIGH
PRESSURE CONTINUES TO PUSH OFF TO THE EAST. THIS WILL LEAD TO
DEVELOPING ISENTROPIC LIFT ACROSS OUR WESTERN AREAS LATE
TONIGHT...SHIFTING UP ACROSS OUR NORTHERN AREAS THROUGH SATURDAY
MORNING. LOW LEVELS ARE FAIRLY DRY SO IT MAY TAKE A LITTLE WHILE
TO SATURATE THE AIR COLUMN. HOWEVER...THINK WE WILL EVENTUALLY
SEE AT LEAST SOME SCATTERED SHOWER ACTIVITY DEVELOP ACROSS THE
WEST LATE TONIGHT AND THEN TRANSITION MORE UP ACROSS OUR NORTHERN
AREAS THROUGH SATURDAY MORNING. SURFACE TEMPERATURES WILL BE AN
ISSUE AS THEY SHOULD SLOWLY RISE OVERNIGHT WITH THE INCREASING
CLOUDS AND WARM ADVECTION...BUT WILL LIKELY STILL BE NEAR OR
BELOW FREEZING AT PCPN ONSET. THE WARMING TEMPERATURES MAY ALSO BE
OFFSET A BIT BY SOME EVAPORATIONAL COOLING EARLY ON WITH THE PCPN.
AS A RESULT...A PERIOD OF FREEZING RAIN WILL BE POSSIBLE LATE
TONIGHT INTO SATURDAY MORNING ACROSS ABOUT THE NORTHWEST HALF OR SO
OF OUR FA. SINCE THERE IS STILL SOME UNCERTAINTY TO THE COVERAGE
AND QPF AMOUNTS SHOULD BE RATHER LIGHT...WILL HOLD OFF ON AN
ADVISORY AT THIS POINT BUT ISSUE AN SPS AND CONTINUE TO MENTION A
FREEZING RAIN THREAT IN THE HWO. TEMPERATURES SHOULD WARM ABOVE
FREEZING ACROSS THE NORTH THROUGH LATE MORNING WITH ANY LINGERING
FREEZING RAIN TRANSITIONING TO LIGHT RAIN. EXPECT HIGHS ON
SATURDAY RANGING FROM THE MID 40S NORTH TO LOWER 50S SOUTH.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
WEAK MID LEVEL RIDGING WILL DEVELOP ACROSS OUR AREA SATURDAY NIGHT
INTO EARLY SUNDAY AHEAD OF SHORT WAVE ENERGY MOVING INTO THE
LOWER MISSISSIPPI VALLEY. THIS SHORT WAVE WILL THEN PIVOT UP INTO
THE OHIO VALLEY THROUGH SUNDAY WITH AN IMPRESSIVE 70 KNOT 850 JET
ROTATING UP INTO OUR AREA THROUGH SUNDAY EVENING. THIS WILL ALLOW
FOR SHOWERS TO OVERSPREAD OUR AREA FROM THE SOUTHWEST THROUGH THE
AFTERNOON AND THEN CONTINUE INTO SUNDAY EVENING. THE 12Z
GFS IS TRYING TO PULL SOME VERY WEAK ELEVATED INSTABILITIES UP
TO ABOUT OUR SOUTHERN BORDER SUNDAY AFTERNOON INTO SUNDAY EVENING.
SUPPOSE AN ISOLATED THUNDERSTORMS IS NOT OUT OF THE QUESTION ACROSS
OUR SOUTH GIVEN THE STRONG FORCING. WILL THEN HANG ON TO LIKELY
POPS THROUGH THE REST OF THE NIGHT AS THE COLD FRONT APPROACHES
FROM THE WEST. IN THE GOOD WAA PATTERN...HIGHS BY SUNDAY WILL BE
WELL INTO THE 50S. GOOD SOUTHERLY FLOW AHEAD OF THE FRONT WILL
LEAD TO STEADY OR EVEN RISING TEMPERATURES SUNDAY NIGHT.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
LATEST ECMWF APPEARS TOO SLOW WITH THE COLD FRONT ON MONDAY. HAVE
GONE WITH THE NAM/GFS/WPC SOLUTION WHICH PUSHES THE COLD FRONT
THROUGH OUR REGION DURING THE MORNING/EARLY AFTERNOON. WITH DECENT
FRONTAL CONVERGENCE AND MOISTURE...A BAND OF SHOWERS IS EXPECTED
TO ACCOMPANY THE FRONT. GIVEN TIGHTENING PRESSURE GRADIENT AND
WINDS 40 TO 50 KNOTS BETWEEN 925 MB AND 850 MB...SOME OF THE
SHOWERS MAY CONTAIN GUSTY WINDS. BY AFTERNOON...MODELS SUGGEST WE
GET INTO A DRY SLOT WHILE THE COLD FRONT MOVES EAST AND LOW
PRESSURE OVER ONTARIO DEEPENS. MODELS INDICATE THAT WE SHOULD MIX
FAIRLY WELL IN THE DRY SLOT. WITH CAA AND MIXING...WINDS COULD
GUST IN THE 30 TO 40 MPH RANGE FROM MID MORNING INTO MID
AFTERNOON.

FOR MONDAY NIGHT INTO TUESDAY...UPPER LEVEL TROUGH WILL TRAVERSE THE
REGION. BEST MOISTURE AND LAKE EFFECT INFLUENCE SHOULD REMAIN TO OUR
NORTH AND HAVE KEPT IT DRY. THERE WILL BE SOME POST FRONTAL CAA
INDUCED STRATOCUMULUS...MOST NUMEROUS ACROSS THE NRN ZONES.

FOR TUESDAY NIGHT...SURFACE HIGH PRESSURE IS EXPECTED TO BRIEFLY
BUILD INTO THE REGION.

FOR THE UPCOMING TRAVEL DAY WEDNESDAY AND INTO THANKSGIVING...ECMWF
AND GFS ARE SIMILAR IN PUSHING A COLD FRONT AND WEAK SFC LOW
PRESSURE THROUGH THE REGION. ECMWF IS A LITTLE SLOWER WHILE THE GFS
IS SLIGHTLY FASTER. IN EITHER CASE...THERE WILL BE A CHANCE OF SNOW
WITH THIS FEATURE AS TEMPERATURES BECOME COLDER ONCE AGAIN IN THE
WAKE OF THE FRONT.

ON FRIDAY...SURFACE HIGH PRESSURE WILL BUILD BACK INTO THE REGION
BEHIND DEPARTING SYSTEM ON THURSDAY.

MONDAY WILL BE THE WARMEST DAY WITH TEMPERATURES NEAR OR A LITTLE
ABOVE NORMAL. THE REMAINDER OF THE EXTENDED WILL FEATURE
TEMPERATURES BELOW NORMAL ONCE AGAIN DUE TO THE NORTHWEST FLOW
PATTERN ALOFT.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
SHOWERS WILL BE WIDELY SCATTERED AS THEY CROSS THE OHIO VALLEY
TOWARDS DAYBREAK...WITH A HIGHER OCCURRENCE NOTED NORTH AND
NORTHWEST OF KDAY. CIGS 5-7KFT WILL LOWER IN THE SHOWERS THAT DO
OCCUR TO APPROACH THE THRESHOLD MVFR 3KFT. DO NOT EXPECT ANY VSBY
RESTRICTIONS WITH THE SHOWERS THAT OCCUR...BUT TEMPS MAY MEAN THAT
THEY ARE FREEZING RAIN WHEN THEY DO FALL. ZR IS NOT EXPECTED AT
KCVG/KLUK AS THE WARM AIR THAT GETS PULLED INTO THE AREA WITH THE
SHOWERS WILL HIT THEM FIRST...AND THEY HAVE AN EVEN LOWER
PROBABILITY OF OCCURRENCE THAN OTHER SITES. KCMH/KLCK COULD GO
EITHER WAY AND I WAS LEANING TOWARDS NOT FREEZING BUT INCLUDED A 2
HOUR PERIOD OF ZR TO BE CAUTIOUSLY PESSIMISTIC HERE.

REMOVED GUSTS THAT WERE IN PREVIOUS FORECAST FOR TODAY IN FAVOR OF
A 12-13KT SUSTAINED WIND THAT WILL PROBABLY CONTINUE INTO THE
EVENING HOURS AT KDAY. DAYTIME CIGS WILL BE 6-8KFT AND PERSIST
INTO THE EVENING.

OUTLOOK...MVFR CIGS POSSIBLE SUNDAY AND MONDAY.
