AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
315 PM EDT TUE AUG 5 2008

.SHORT TERM (TONIGHT AND WEDNESDAY)...

THE NAM HAD A GOOD HANDLE ON THE PRECIPITATION EARLIER THIS MORNING
SO WILL FOLLOW THE NAM FOR THE REMAINDER OF THE PERIOD. MAIN CONCERN
WILL BE THE POSSIBILITY OF STRONG TO SEVERE STORMS THIS AFTERNOON
AND EVENING HOURS. MID 70 DEWPOINTS ADVECTING INTO THE WRN FA WILL
INCREASE THE CHANCE OF CONVECTION ALONG THE CONVERGENCE BOUNDARY
AHEAD OF A COLD FRONT OVER NRN IL/IN. IF THE MLCAPES OF 2000+ J/KG
CAN BE REALIZED...THEN STRONG TO SVR STORMS COULD FORM OVER SRN
IL/WRN KY...AND PUSH EASTWARD INTO OUR WRN CWA. THE MAIN THREATS
WOULD BE DAMAGING WINDS...FOLLOWED BY A MARGINAL HAIL THREAT. THE
SOUTH WILL REMAIN MOSTLY DRY THIS EVENING WITH A CHANCE OF AN
ISOLATED CELL OR TWO IF THE PREFRONTAL BOUNDARY STAYS INTACT.

CONTINUING WITH THE NAM...THE NEXT CHANCE OF PRECIPITATION WILL BE
OVERNIGHT INTO WEDNESDAY MORNING WHEN THE COLD FRONT DROPS SOUTH
TOWARD THE OHIO RIVER. A SHORTWAVE TROUGH CURRENTLY IN SOUTH DAKOTA
WILL MAKE ITS WAY DOWN INTO THE FA AT THE SAME TIME...WHICH WILL
HELP DEVELOP SHOWERS/STORMS OVER THE NWRN CWA AROUND ROUGHLY 06Z-12Z
WEDNESDAY CONTINUING ESE ACROSS THE CWA INTO WEDNESDAY MORNING. THE
FRONT WILL STALL OUT IN THE AFTERNOON ACROSS SRN KY...WHICH MAY
FOCUS THE PRECIPITATION SOUTH OF THE OHIO RIVER IF IT HOLDS
TOGETHER. A TEMPERATURE ISSUE WILL BE THE MAIN FACTOR ON WEDNESDAY
WITH THE LOCATION OF THE PRECIPITATION. WILL KEEP THE EAST COOLER
DUE TO PRECIPITATION AND CLOUD COVER SINCE IT WILL BE HARD TO
RECOVER ONCE THE FRONT MOVES THROUGH.

.LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)...

FOR THE EARLY PART OF THE LONG TERM...AN UPPER LEVEL TROUGH WILL
MOVE THROUGH NORTHWEST FLOW WITH A COLD FRONT DROPPING TO THE SOUTH.
BEYOND THE WEEKEND...MODELS DIFFER IN THEIR SOLUTIONS AND WILL LEAN
TOWARD THE ECMWF WITH THE UPPER FLOW FLATTENING AND FRONTS BECOMING
MORE STATIONARY EAST TO WEST THE FIRST PART OF THE WEEK. GFS REMAINS
MORE AMPLIFIED IN ITS SOLUTION BUT IS BEGINNING TO TREND MORE TOWARD
ECMWF TO OUR WEST SO WILL LEAN MORE HEAVILY ON ECMWF SOLUTION.

WEDNESDAY NIGHT THROUGH THURSDAY NIGHT...
AT THE BEGINNING OF THE THE LONG TERM A COOL FRONT WILL BE MOVING
SOUTH THROUGH CENTRAL KENTUCKY WITH SHOWERS AND THUNDERSTORMS
OCCURRING ACROSS THE AREA. THE SHOWERS WILL DIMINISH ACROSS THE FAR
NORTH TOWARD MORNING THEN END FROM THE NORTH DURING THE DAY THURSDAY
AS THE FRONT SETTLES TO THE SOUTH.

DRIER AIR WILL SPREAD INTO THE AREA THURSDAY NIGHT WITH CLOUDS
DECREASING FROM THE NORTH AS A MID LEVEL TROUGH DEEPENS ACROSS THE
APPALACHIANS AND UPPER AIR RIDGING STRENGTHENS OVER THE NORTHERN AND
CENTRAL PLAINS.

FRIDAY THROUGH SUNDAY...
SURFACE HIGH PRESSURE WILL BUILD INTO THE AREA BEHIND THE FRONT ON
FRIDAY AND WILL SETTLE OVER THE LOWER OHIO VALLEY ON SATURDAY.
COOLER AIR BROUGHT SOUTH BY NORTHERLY WINDS AHEAD OF THE FRONT WILL
KEEP TEMPERATURES A LITTLE COOLER WITH HIGHS IN THE 80S.

MEANWHILE THE MID AND UPPER FLOW WILL BECOME MORE ZONAL FOR THE
EARLY PART OF NEXT WEEK.

SUNDAY NIGHT THROUGH TUESDAY...
WITH LEANING MORE TOWARD THE ECMWF AND A FLATTER MORE ZONAL FLOW...
EAST TO WEST FRONTS WILL BECOME MORE STATIONARY NEAR THE OHIO
VALLEY. THIS WILL RESULT IN INCREASED CHANCES FOR SHOWERS AND
THUNDERSTORMS OVER THE AREA FOR THE LATTER PART OF THE FORECAST
PERIOD.

A WARM FRONT THAT WAS LOCATED OVER WESTERN MISSOURI AND ARKANSAS
DURING THE DAY SUNDAY WILL ADVANCE EAST TO THE MISSISSIPPI RIVER BY
MONDAY MORNING. CLOUDS AND RAIN WILL SPREAD EAST ACROSS THE AREA
SUNDAY NIGHT AHEAD OF THE FRONT WITH THE FRONT BECOMING STATIONARY
ACROSS SOUTHERN KENTUCKY AND TENNESSEE. A SECOND FRONT WILL DROP
SOUTH INTO CENTRAL INDIANA BY TUESDAY MORNING. SHOWERS AND
THUNDERSTORMS WILL BE SCATTERED OVER THE AREA FOR THE LATTER PART OF
THE LONG TERM. THE CLOUDS AND SHOWERS WILL HOLD HIGH TEMPERATURES IN
THE 80S.

&&

.AVIATION (18Z TAFS)...

EARLIER SHRA/TSRA ARE MOVING OFF TO THE EAST...AND WILL CONTINUE TO
AFFECT THE LEX TERMINAL THROUGH 19Z. OTHERWISE ISOLATED TO SCATTERED
SHRA/TSRA MAY AFFECT THE SDF AND LEX TERMINALS THROUGH 2Z. MAY EVEN
INCLUDE A VCSH OR VCTS AT THE BWG TERMINAL DUE TO AN OUTFLOW
BOUNDARY MOVING SOUTH WHICH MAY SPARK A RENEGADE SHOWER OR TWO
THROUGH 22Z.

MORE CONVECTION WILL DEVELOP OVERNIGHT ALONG AN APPROACHING COLD
FRONT. THE BEST CHANCE FOR THIS PRECIP TO AFFECT THE SDF TERMINAL
WILL BE BETWEEN 6 AND 12Z WEDNESDAY MORNING. WILL INCLUDE THIS IN
THE SDF TAF AND A FEW HOURS LATER IN THE LEX TAF. HOWEVER WILL KEEP
PRECIP WORDING WITHIN THE VICINITY AT BWG SINCE THE FRONT WILL BE
NORTH OF THERE. MAY HAVE MVFR TO IFR VSBYS OVERNIGHT DUE TO
MIST/FOG. OTHERWISE MVFR CIGS WILL BE POSSIBLE WITH ANY
THUNDERSTORM.
