AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
223 AM CST THU MAR 13 2003

AREA OF CONVECTION AROUND 200 AM...EXTENDED FROM CNTRL IL INTO
SCNTRL AND SW MO. DESPITE WELL DEVELOPED LOOK TO CONVECTION...AND
SEEMINGLY SELF GENERATED COLD POOL...CONVECTION CONTINUES TO
ENCOUNTER LESS INSTABILITY...AND CONTINUES TO BE OUTFLOW DOMINATED
ON THE SOUTHERN END. THUS SEVERE WX POTENTIAL ACROSS THE FA APPEARS
VERY LOW. BUT HIGH PROBABILITY OF RAIN AND A FEW THUNDERSTORMS
NONE THE LESS. WILL MOVE CONVECTION OUT OF THE AREA BY MID
MORNING...AS REGIONAL RADAR TRENDS SUGGEST THE BACK EDGE OF THE
PRECIPITATION SHOULD BE INTO SE MO AND SW IL BY ABOUT 6 AM.

NOT A HIGH CONFIDENCE CALL ON CLOUDS TODAY. MESOETA AND NGM MUCH
MORE AGGRESSIVE IN FCSTING LOW CLOUD POTENTIAL TODAY...BUSTING THE
LOW TROP MOISTURE UP SOME LATER THIS AFTERNOON. AVN MUCH MORE
OPTIMISTIC. WILL PLAY A MIDDLE OF THE ROAD GAME FOR NOW...BUT HEDGE
MORE PESSIMISTIC EARLY ON.

WX STILL LOOKS DRY TONIGHT THROUGH SATURDAY NIGHT. MODELS SUGGEST
A WEAK CIRCULATION WILL CUT ITSELF OFF THE MAIN BRANCH...SOMEWHERE
ACROSS THE GULF COAST STATES. THIS MAY BACK MORE CLOUDS INTO OUR
EASTERN COUNTIES OF W KY BY THEN (SAT). HOWEVER...MODELS KEEP PRECIP
OFF TO THE EAST. WILL MONITOR THIS SYSTEM.

LEFT GRIDS/ZFP FCST UNCHANGED FROM SUNDAY ON THROUGH NEXT WEDNESDAY.
DAY SHIFT MAY NEED TO REVISIT SUNDAY CHANCE OF PRECIPITATION. IF THE
WEAK UPPER CIRCULATION PANS OUT...AND DRIFTS NE ACROSS THE
APPALACHIANS AS FCST...WE MAY BE IN A DECENT SUBSIDENCE REGION TO
THE WEST OF THE LOW...PRECLUDING ANY PRECIP ON SUNDAY. ECMWF...AND
FRESH NEW MRF DATA STILL ADVERTISE BIG TROF OVER THE MID SECTION OF
THE CONUS EARLY AND MID PART OF NEXT WEEK. EXACTLY HOW THE MID TROP
FLOW PATTERN WILL EVOLVE OVER THE MIDDLE OF THE NATION REMAINS TO BE
SEEN.

FOR TEMPS...STUCK PRETTY CLOSE TO GOING GRID VALUES...AND
INCORPORATED A COMPROMISE OF MAV AND FWC FOR MAXS TODAY AND FRIDAY.

.PAH...NONE.
