What happened

The dense fog was mainly west of a line from Marion to Princeton to Hopkinsville. Visibility was frequently below one-quarter mile.

.DISCUSSION...
RADAR MOSAIC THIS AFTN SHOWED A GENERAL DECREASING TREND IN THE
OVERALL PCPN FROM WEST TO EAST...WHICH SEEMED TO CONFIRM THE
BEGINNING OF BUILDING PRESSURE HEIGHTS INTO THE PAH FCST AREA...AND
DRYING OF MID/UPPER LEVELS. HOWEVER...SUBTLE RIPPLES IN THE MID
LEVEL FLOW MAY PROVIDE ENOUGH VERTICAL MOTIONS TO ACT ON LOW LEVEL
MOISTURE THROUGH THE REST OF THE DAYTIME...ESPECIALLY IN THE ERN
HALF. WE SHOULD BE PCPN FREE BY SUNRISE FOR SURE AS A SHARP MID
LEVEL RIDGE BUILDS IN AHEAD OF THE NEXT SYSTEM.

AT THE SFC...A BACK DOOR TYPE FRONT LURKED JUST TO THE NE OF THE
FCST AREA..AND THIS FRONT MAY BE THE FOCUS FOR SOME SHOWER ACTIVITY
OVER THE NEXT COUPLE OF DAYS. AS A MID LEVEL SHORTWAVE IN THE WRN
ATLANTIC IMPINGES UPON THE RIDGE OVER OUR AREA...ITS ASSOCIATED AREA
OF HIGH SFC PRESSURE WILL TEND TO PUSH THE BACK DOOR FRONT SWWD
ACROSS THE PAH FCST AREA ON THU. THEN THE FRONT IS EXPECTED TO MOVE
BACK NEWD IN RESPONSE TO LOWERING PRESSURES ACROSS THE CENTRAL
PLAINS. ALL THIS SHOULD RESULT IN A LOW CHANCE POP FOR MUCH OF THU
AND FRI.

A MID LEVEL SHORTWAVE IS EXPECTED TO SPIN OFF FROM A LARGE LOW IN
THE WRN CONUS...AS THE LOW OPENS AND LIFTS TOWARD CANADA BY THE
WEEKEND. WITH THE APPROACH OF THE SHORTWAVE...LARGE SCALE LIFT AND
WAA WILL COMMENCE ON FRI NIGHT ACROSS OUR AREA. THERE WILL PROBABLY
BE TWO EPISODES OF CONCENTRATED PCPN AND THUNDER...ONE WITH THE SFC
LOW FRI NIGHT...THEN ONE WITH THE SLOW MOVING COLD FRONT. ATTM...SVR
WX IS POSSIBLE DURING THIS PERIOD BUT NOT ALL THAT LIKELY DUE TO
SOMEWHAT UNIDIRECTIONAL WIND FIELDS AND LIMITED INSTABILITY.

THUS...TEMPS WILL CONTINUE TO BE ABOVE NORMAL THROUGH THE WEEKEND.

IN THE EXTENDED...THE SHARP MID LEVEL TROF AND THE ATTENDANT WEAK
SFC COLD FRONT AND PCPN SHOULD MOVE OUT OF THE FCST AREA DURING THE
MORNING HOURS ON SUNDAY...ALLOWING GENERALLY CLEAR AND DRY
CONDITIONS WITH LIGHT WINDS FOR THE FIRST PART OF THE WEEK. THE MED
RANGE MODELS SEEMED TO BE SYNCED UP FAIRLY WELL WITH THE OVERALL
MASS FIELD PATTERN THROUGH DAY5/MON/...HOWEVER THE 06Z OPERATIONAL
GFS/DGEX APPEAR TO BE THE OUTLIERS BEYOND THAT. THE NEXT DECENTLY
AMPLIFIED MID LEVEL SHORTWAVE TROF TO DIG ACROSS THE MIDDLE OF THE
NATION BY THE BEGINNING OF DAY7 WAS NOT REALLY SHOWN BY THE 06Z OP
GFS OR DGEX...BUT EVEN THE ECMWF HAS SOME RUN TO RUN VARIABILITY.
THE ASSUMPTION FOR THIS PACKAGE WILL BE THAT THE TROF SHOULD BRING
ANOTHER COLD FRONT AND SHOWERS/TSTMS INTO THE REGION SOMETIME ON
DAY7...THE 12Z OP GFS NOW SEEMS TO SHOW THIS. THIS SHOULD RESULT IN
GREATER WAA IN THE LOW LEVELS AND THEREFORE HIGHER TEMPS AHEAD OF
THE FRONT THAN PREVIOUSLY FCST...BUT NOT TOO FAR OFF CLIMATOLOGICAL
AVERAGES.
