AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE PADUCAH KY
110 PM CST TUE DEC 18 2001

...MAIN FORECAST CONCERN NEXT COUPLE OF DAYS WILL BE FOG THREAT
TONIGHT...

MODELS IN FAIRLY GOOD AGREEMENT WITH THE OVERALL WEATHER PATTERN
THROUGH THE REST OF THE WORK WEEK. SURFACE RIDGE BUILDING INTO THE
REGION TODAY HAS FINALLY BROUGHT A RETURN TO SUNSHINE THIS
AFTERNOON. NEXT FRONT...NOW OVER THE PLAINS...WILL SLIDE EAST
TONIGHT...AND SHOULD BE LOCATED OVER SOUTHERN IL/SOUTHEAST MO BY
SUNRISE WED. ASSOCIATED H50 VORT MAX IS FAIRLY IMPRESSIVE WITH THIS
SYSTEM...BUT LOW LEVEL RETURN FLOW IS VIRTUALLY NIL AND THUS OVERALL
INTEGRATED MOISTURE IS MARGINAL. CURRENT FORECAST IS FOR CLOUDS
ONLY. MAY INTRODUCE SPRINKLES IN SOME AREAS...ESPECIALLY NORTH...ON
WED...BUT WILL LIKELY STAY AWAY FROM MEASURABLE PRECIP.

MAIN QUESTION TONIGHT WILL BE HOW MUCH...IF ANY...FOG REFORMS. WINDS
SHOULD DECOUPLE AROUND SUNSET...AND EXPECT AT LEAST PATCHY FOG TO
FORM BEFORE MIDNIGHT IN FAVORED LOCATIONS. CLOUDS WILL MOVE INTO
WESTERN AREAS LATE AND MAY PRECLUDE WIDESPREAD DENSE FOG. CLOUDS
SEEM MORE IFFY SOUTH/EAST OF THE OHIO RIVER. THUS...FOG SEEMS LIKE A
BETTER BET THERE. WILL BRIEF EVENING CREW.

HIGH PRESSURE WILL MAINTAIN ITS PRESENCE THROUGH FRIDAY...WHICH
SHOULD GIVE US A GOOD CHANCE TO DRY OUT A BIT AND FLOOD WATERS A
CHANCE TO RECEDE. NEXT CHANCE OF SHOWERS AND STORMS WILL COME LATER
SATURDAY INTO SUNDAY AS ANOTHER STRONG SYSTEM TREKS EAST THROUGH THE
PLAINS...LEADING TO MAJOR PATTERN CHANGE BY MONDAY AND INTO
CHRISTMAS DAY. MORE ON THIS AS IT APPROACHES.

WILL SIDE WITH SLIGHTLY COOLER AVN MOST TEMPS ON WED DUE TO LOW
THICKNESSES AND PLENTY OF CLOUD COVER.

.PAH...NONE.
