What happened
The episode as NWS PAH wrote it up.
Widespread dense fog reduced visibility to one-quarter mile or less across parts of northwest Kentucky. The most persistent dense fog was generally along and north of a line from Marion to Calhoun, including the Henderson and Owensboro areas. Weak high pressure was responsible for light winds. The light winds, combined with saturated ground from snowmelt and heavy rain, set the stage for dense fog.

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 1255 PM CDT TUE MAR 10 2015
RADAR MOSAICS SHOW WIDESPREAD RAIN RAPIDLY LEAVING THE AREA THIS
AFTERNOON...LEAVING BEHIND SOME AREAS OF DRIZZLE...AS A SFC LOW
MOVES NEWD AWAY FROM THE PAH FORECAST AREA. THERE WILL BE A SMALL
CHANCE OF MEASURABLE RAINFALL OVER PARTS OF THE PENNYRILE REGION
OF KY TONIGHT...WITH PATCHY FOG POSSIBLE ABOUT ANYWHERE.
OTHERWISE...SKIES ARE EXPECTED TO GO MOSTLY CLEAR FOR MUCH OF
WED. UNDER WEAK FLOW ALOFT...AND HIGH PRESSURE AT THE SFC...WEAK
SFC WINDS WILL START OUT NRLY...VEERING TO ERLY BY THU. MEANWHILE...
ON THU THERE WILL BE RAMP-UP OF POPS AND CLOUD COVER AS ANOTHER
LOW PRESSURE SYSTEM EJECTS FROM A PERSISTENT SWRN CONUS LONGWAVE
MID/UPPER TROF...AND HEADS UP THE MS RIVER VALLEY.
.LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 300 PM CDT TUE MAR 10 2015
THURSDAY NIGHT THROUGH FRIDAY NIGHT...
RAIN WILL BE WIDESPREAD ACROSS THE QUAD STATE AREA THURSDAY NIGHT
THROUGH FRIDAY EVENING. THIS IS IN RESPONSE TO DEEP SOUTHERLY FLOW
THAT WILL RESULT IN STRONG MOISTURE TRANSPORT INTO THE LOWER OHIO
VALLEY AHEAD OF A CLOSED UPPER LOW OVER THE SOUTHERN PLAINS.
PRECIPITABLE WATER VALUES ARE PROGGED TO RISE TO AROUND 1.5 INCHES
WHICH IS QUITE ANOMALOUS FOR EARLY-MID MARCH. ALSO...THE K INDEX
RISES INTO THE LOWER TO MID 30S...ANOTHER INDICATOR OF HEAVY RAIN
POTENTIAL. RAIN MAY BE LOCALLY HEAVY AT TIMES. MODEL SOUNDINGS
SUGGEST SLIGHT ELEVATED INSTABILITY COULD BE PRESENT WITHIN THE
RAIN...ESPECIALLY ON THE BACK EDGE FRIDAY AFTERNOON/EVENING...BUT IT
LOOKS LIKE PREDOMINANTLY A RAIN EVENT WITH EMBEDDED HEAVIER SHOWERS.
TOTAL RAINFALL AMOUNTS OF 1 TO 2 INCHES APPEAR LIKELY FROM THIS
SYSTEM WITH ISOLATED HIGHER AMOUNTS...WHICH COULD CAUSE LOCAL FLOOD
CONCERNS.
SATURDAY...
UPPER LOW WEAKENS AS IT LIFTS NORTHEAST AS A STRONG SEPARATE
SHORTWAVE MOVES SOUTHEAST ACROSS THE GREAT LAKES. THERE COULD BE
SOME RESIDUAL SPOTTY LIGHT SHOWERS ON SATURDAY...BUT THE BRUNT OF
THE RAIN WILL BE OVER. ALL PRECIPITATION WILL EXIT THE QUAD STATE
AREA SATURDAY NIGHT. AFTERNOON TEMPERATURES SHOULD BE QUITE MILD IN
THE UPPER 50S AND 60S.
SUNDAY THROUGH TUESDAY...
RIDGING BUILDS IN ALOFT ALONG WITH HIGH PRESSURE AT THE SURFACE.
THIS WILL KEEP WEATHER CONDITIONS DRY SUNDAY AND MONDAY. IT MAY BE A
BIT COOLER SUNDAY AFTERNOON...BUT STILL IN THE 50S TO LOWER 60S...
WITH HIGHS MONDAY AFTERNOON BACK IN THE 60S ACROSS MUCH OF THE
REGION. ON TUESDAY...CONTINUED DRY BUT COOLER WEATHER IS EXPECTED AS
A COOL FRONT PASSES THROUGH OUR AREA...AND AS ANOTHER SOUTHERN U.S.
SYSTEM KEEPS MOISTURE SOUTH AND WEST OF THE LOWER OHIO VALLEY.

.AVIATION...
ISSUED AT 646 PM CDT TUE MAR 10 2015
A SURFACE LOW PASSED NORTHEAST THROUGH THE REGION THIS
AFTERNOON...AND IN ITS WAKE THE PRESSURE GRADIENT IS VERY FLAT.
THEREFORE...WINDS WILL BE LIGHT THROUGH THE PERIOD...AND THE
IFR/LIFR CONDITIONS ARE LIKELY TO LINGER OVER ALL SITES THROUGH
THE NIGHT. SOME GUIDANCE EVEN HINTS AT VLIFR CONDITIONS...AND WILL
NOT BE SURPRISED IF THEY DEVELOP. LOOKS LIKE IT SHOULD MIX OUT IN
THE LATE MORNING OR EARLY AFTERNOON HOURS.
