AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
1225 PM CDT TUE AUG 5 2003

FORECAST CONCERN THIS PACKAGE IS HOW LONG TO KEEP CHANCE POPS IN THE
FORECAST.

A WEAK SURFACE BOUNDARY WAS POSITIONED ACROSS THE SOUTHERN HALF OF
THE FORECAST AREA. DENSE FOG DEVELOPED LAST NIGHT IN AREAS JUST
NORTH OF THIS BOUNDARY. WITH LITTLE CHANGE IN THE BOUNDARY LAYER
CONDITIONS...I/M HAVING TROUBLE FINDING MANY REASONS WHY A SIMILAR
EVENT WILL NOT HAPPEN TONIGHT. CLOUD COVER APPROACHING FROM THE
NORTHWEST MAY HINDER THIS A BIT SO WILL ONLY MENTION /PATCHY DENSE
FOG/.  TONIGHT...AN AREA OF WEAK LOW PRESSURE...CURRENTLY OVER
OKLAHOMA...IS EXPECTED TO SLOWLY HEAD EAST TOWARDS THE
MID-MISSISSIPPI VALLEY. THIS WILL HELP LIFT THE AFOREMENTIONED
BOUNDARY BACK ACROSS THE AREA AND ACT AS A FOCUS FOR CONVECTIVE
DEVELOPMENT. ALSO WEDNESDAY A SHORTWAVE TROUGH IN THE NORTHWEST FLOW
IS PROGGED TO HEAD ACROSS THE NORTHERN PART OF THE AREA...THUS
HELPING THE CONVECTIVE POTENTIAL. TONIGHT WILL CONFINE PRECIP
CHANCES TO THE SOUTHWEST. ON WEDNESDAY WILL HAVE CHANCE POPS ALL
LOCATIONS WITH THE HIGHEST PERCENTAGE SOUTHWEST. WILL LINGER CHANCES
INTO THE EVENING HOURS WEDNESDAY DUE TO DIURNAL AFFECTS.

THURSDAY ANOTHER WEAK SHORTWAVE THROUGH PROGRESSING THROUGH THE
NORTHWEST FLOW MAY TRIGGER ADDITIONAL CONVECTION. ESPECIALLY ACROSS
EASTERN PARTS OF THE AREA. WILL HAVE NO MORE THAN A 30 POP EAST.

FROM FRIDAY INTO THE BEGINNING OF THE WEEKEND...THE UPPER RIDGE IN
THE WEST BUILDS A LITTLE STRONGER AND CLOSER TO THE AREA...HELPING
TO SHUNT THE ACTIVE WEATHER EAST OF THE REGION. WILL CONTINUE WITH A
DRY AND SLIGHTLY COOLER THAN NORMAL FORECAST FOR THIS PERIOD.

BY THE END OF THE WEEKEND...GUIDANCE IS IN AGREEMENT OF A TREND FOR
THE UPPER RIDGE IN THE WEST TO RETROGRADE FARTHER WEST AND THUS
ALLOW FOR THE UPPER TROUGH TO ALSO RETROGRADE CLOSER TO THE AREA.
THE DIFFERENCES COME IN THE FORM OF JUST HOW QUICKLY THAT TAKES
PLACE AND HOW LONG OF A PERIOD OF TIME THE INFLUENCE OF THE RIDGE
KEEPS ANY NORTHWEST-FLOW SHORTWAVE TROUGHS FROM AFFECTING OUR
WEATHER. THE GFS IS MORE AGGRESSIVE IN RETURNING THE FORECAST AREA TO
A WETTER PATTERN BY MONDAY. THE ECMWF THROUGH MONDAY STILL SHOWS THE
AXIS OF A STRONGER RIDGE CLOSER TO THE AREA. THE CANADIAN SOLUTION
WAS ABOUT A DAY QUICKER THAN THE GFS HAVING A RETURN OF PRECIP TO
THE AREA AS EARLY AS SUNDAY. WILL GO WITH THE CONSENSUS OF THE THREE
WHICH WOULD AVERAGE CLOSE TO THE GFS.
