What happened

The episode as NWS PAH wrote it up.

Widespread dense fog shrouded western Kentucky during the night of the 8th and through the early morning hours of the 9th. Visibility was reduced to one-quarter mile or less. A warm front along the Kentucky/Tennessee border during the evening moved north to the Ohio River Valley by early on the 9th. The dense fog formed along and ahead of the warm front, then lifted as southwest winds increased following the passage of the front.

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 Paducah, KY wrote its last area forecast discussion before the first event at Dec 8, 5:50 PM CST, 2 hours 10 minutes earlier.

.DISCUSSION...
ONGOING PCPN ON ISENTROPIC UPGLIDE OVERTOP WARM FRONT STILL PERCHED
JUST TO THE SOUTH. GFS/SREF MODELS THIS PCPN MOST REASONABLY AND
LIFTS IT NORTH TONIGHT-SUNDAY...STRADDLING THE BOUNDARY SOMEWHERE
ACROSS THE LOWER OH VALLEY BY SUN PM/EVENING. THIS SETS THE STAGE
FOR DEEPER SWLYS DEVELOPED BY THEN TO EJECT WAVES OF ENERGY TO SHOOT
OUT OF SRN PLAINS AND OVERTOP LOWER OH VALLEY AND AFOREMENTIONED
BOUNDARY...AS ELEVATED STABILITY PARAMETERS BECOME SUPPORTIVE OF
MENTION OF THUNDER...BEGINNING TOMORROW AND LASTING THRU LIFE OF
BOUNDARY/SYSTEMS MEANDERING PROXIMITY TO THE AREA...WHICH IS TO SAY
THRU WED/WED NIGHT. OFF AND ON HIGH POPS EVENT MESHES W/ HPC ISSUED
2-3 OUTLOOK AND WE WILL CONTINUE TO HIT HARD ON HWO.

WED NIGHT-THU THE SYSTEM PASSES AND COLD AIR COMES IN HARD FROM THE
WEST AND NORTHWEST...BUT THE MOISTURE IT CAN TAP HAS ALREADY
DEPARTED TO THE EAST. THEREFORE ELIMINATED ITS MENTION THIS
PACKAGE...BUT AS THIS HAS BEEN AN OSCILLATING FEATURE OF THE PAST
FEW DAYS PACKAGES (SYSTEM DEPARTURE)...WILL KEEP A CLOSE EYE UPON
SUBSEQUENT RUNS TIMING CHANGES AND ADJUST ACCORDINGLY.

GIVEN OUR GFS/SREF BIAS OUR FORECAST TEMPS ARE IN DIRECTION OF GFS
BASED MAV MOS IN THE NEAR TERM. EXCEPTION IS 1ST 12 HOURS AS NO
MODEL CAPTURES COOL EFFECT WELL AND WE MAY WELL BE CLOSER TO NGM
BASED FWC THERE. MEDIUM TO LONG RANGE WE MAINTAIN A PERSISTENCE
STRATEGY FORECAST THAT HAS BEEN ONGOING AND BLEND WITH HPC/COLLAB
PICTURE MORESO THAN ANY PARTICULAR MOS DATA SET.

.AVIATION...
SHALLOW INVERSION NORTH OF SURFACE WARM FRONTAL BOUNDARY ACROSS NW
TENNESSEE AND NE ARKANSAS...SHOULD RESULT IN INCREASED SHEAR
MAGNITUDE WITH E OR ENE SFC WINDS...AND WINDS ABOUT 2K FT RUNNING
220/230 DEG AT 20-30KTS TONIGHT. GOOD COMBO AND VECTOR AND SCALAR
CALCULATED SHEAR WARRANTS THE INCLUSION OF WIND SHEAR IN THE TAFS
FOR TONIGHT. EXPECT IFR TO LIFR CIGS AND VSBYS TO PERSIST TONIGHT.
EXPECT TO SEE SOME IMPROVEMENT IN VSBYS AFTER THE WARM FRONT LIFTS
JUST NORTH OF THE TAF SITES EARLY TOMORROW. OTHERWISE...ANTICIPATE
ON AND OFF DRIZZLE OR LIGHT RAIN TO CONTINUE. THERE MAY BE SOME RAIN
SHOWER OR ISOLD TSRA ACTIVITY TOMORROW TOO...BUT PROBABILITY TOO LOW
TO ADDRESS OR INCLUDE ATTM.
