AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
300 PM EDT THU AUG 27 2009

.AVIATION UPDATE (18Z TAFS)...

.SHORT TERM (TONIGHT AND FRIDAY)...

THE CHALLENGE EARLY THIS EVENING WILL BE FORECASTING THE TIMING AND
LOCATION OF ANY SCATTERED CONVECTIVE ACTIVITY. SATELLITE AND SURFACE
ANALYSIS EARLIER AROUND 2 PM INDICATED A NEARLY STATIONARY FRONT
DRAPED IN AN EAST-WEST FASHION JUST SOUTH OF INDIANAPOLIS. THIS
BOUNDARY WILL PROBABLY NOT REACH OUR SOUTHERN INDIANA COUNTIES THIS
EVENING OR OVERNIGHT.

ALL OF OUR AREA IS WEAKLY UNSTABLE WITH A BIT OF A CAP AROUND 13K
FEET. SCATTERED SHOWERS WITH ISOLATED THUNDER HAVE ALREADY DEVELOPED
IN AN UNORGANIZED FASHION ACROSS SOUTHERN INDIANA ARCING INTO THE
BLUEGRASS REGION. EXPECT THESE STORMS TO STAY ISOLATED ACROSS
SOUTHERN INDIANA...BUT INCREASE TO SCATTERED ACROSS THE BLUEGRASS
REGION BY LATE AFTERNOON OR EARLY EVENING. WITH VERY WEAK WINDS
ALOFT...ANY SHOWERS WILL TEND TO MOVE NORTH VERY SLOWLY AND RAIN TO
RAIN THEMSELVES OUT THESE SHOWERS WILL ALSO PRODUCE OUTFLOW
BOUNDARIES THAT MAY EVENTUALLY SPARK OTHER STORMS. ISOLATED AREAS
WILL EXPERIENCE BRIEF DOWNPOURS AND A VERY QUICK HALF-INCH OF RAIN
OR MORE.

A WEAK 500MB CUTOFF LOW NOW OVER THE MOUTH OF THE MISSISSIPPI WILL
MOVE NORTHEAST ACROSS ALABAMA AND WILL EVENTUALLY DISSIPATE ACROSS
THE SOUTHERN APPALACHIANS. MID LEVEL MOISTURE HAS MOVED NORTH ACROSS
EASTERN TENNESSEE AND IS FORECAST TO MOVE INTO THE LAKE CUMBERLAND
REGION AND THE BLUEGRASS REGION THIS EVENING THROUGH THE EARLY
MORNING HOURS FRIDAY. THE LOCAL WRF AND THE 12Z MESO-NAM BOTH SHOW
CONVECTION DEVELOPING THIS EVENING ALONG/EAST OF INTERSTATE 75. WILL
INCREASE POPS TO 40 TO 50% ACROSS OUR EASTERN COUNTIES THIS EVENING.

SYNOPTICALLY ACROSS THE NATION AS A WHOLE...500MB PATTERN WILL
AMPLIFY BEGINNING TOMORROW. JET ENERGY WILL DIVE SOUTHWARD ACROSS
THE NORTHERN PLAINS FRIDAY AS RIDGING MOVES NORTH ACROSS BRITISH
COLUMBIA. THIS WILL QUICKLY FORM A CLOSED LOW OVER THE WESTERN GREAT
LAKES EARLY SATURDAY.

FRIDAY WILL BE OUR LAST WARM HUMID DAY FOR AWHILE. FORECASTING
PRECIPITATION CHANCES TOMORROW WILL BE CHALLENGING. CENTRAL KENTUCKY
WILL LIE IN BETWEEN WIDESPREAD CLOUDINESS AND LIKELY SHOWERS OVER
THE SOUTHERN APPALACHIANS AND EASTERN TENNESSEE...AND CONVECTION
ASSOCIATED WITH A COLD FRONT EXPECTED ACROSS ILLINOIS AND EASTERN
MISSOURI. WILL KEEP ISOLATED TO SCATTERED SHOWERS FOR TOMORROW WITH
CHANCES INCREASING TO AROUND 40 TO 50% ACROSS SOUTHERN INDIANA LATE
IN THE AFTERNOON AND EVENING. THE COLD FRONT WILL CROSS THE OHIO
RIVER DURING THE EARLY MORNING HOURS SATURDAY. WILL INCREASE POPS TO
50% LATE TOMORROW EVENING THROUGH THE EARLY MORNING HOURS
SATURDAY.

.LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)...

FRIDAY NIGHT THROUGH SUNDAY...

A DEEPENING UPPER LEVEL TROUGH AND CLOSED LOW NORTH OF LAKE SUPERIOR
AT THE BEGINNING OF THIS FORECAST PERIOD WILL DIG INTO THE GREAT
LAKES REGION AND THEN QUICKLY SHIFT TO THE NORTHEAST. THIS WILL
SERVE TO PUSH A COOL FRONT THROUGH THE LOWER OHIO VALLEY LATE FRIDAY
NIGHT AND SATURDAY MORNING AND WE WILL MENTION HIGH CHANCE POPS FOR
THIS 6 HOUR PERIOD. BUFKIT SOUNDINGS FOR THIS TIME INDICATE ONLY A
MARGINALLY UNSTABLE ATMOSPHERE BUT PRECIPITABLE WATER VALUES ARE IN
EXCESS OF 2 INCHES SO THE MAIN CONCERN WILL BE PERIODS OF HEAVY
RAIN. WE WILL HOLD ONTO DIMINISHING CHANCES OF SHOWERS SATURDAY AS
COOLER AIR FILTERS INTO THE REGION. THE UPPER LEVEL TROUGH DOES NOT
CROSS THE REGION UNTIL SUNDAY BUT WITH A DRY NORTHWEST FLOW I DO NOT
SEE ANY ADDITIONAL PRECIPITATION AT THIS TIME.

SO WITH THE UPPER TROUGH HOLDING BACK WESTERLY LOW LEVEL WINDS WILL
KEEP TEMPERATURES SATURDAY SOMEWHAT WARM WITH HIGHS FROM THE UPPER
70S TO LOWER 80S. COOLER READINGS WILL BE NOTED SUNDAY AS THE WINDS
SHIFT TO THE NORTHWEST.

MONDAY THROUGH THURSDAY...

THE AFOREMENTIONED UPPER LOW WILL SHIFT TO THE NORTHEAST EARLY IN
THE PERIOD WITH THE TROUGH GRADUALLY SHIFTING TO THE EAST COAST. AT
THE SURFACE COOL HIGH PRESSURE WILL DROP INTO THE MID MISSISSIPPI
VALLEY AND SHIFT EAST TO OHIO BY THURSDAY. THIS WILL PROVIDE THE
LOWER OHIO VALLEY WITH MOSTLY SUNNY DAYS AND CLEAR NIGHTS. ALTHOUGH
NOT AS COOL AS EARLIER EXPECTED... TEMPERATURES WILL BE SEASONABLY
COOL FOR EARLY SEPTEMBER.

&&

.AVIATION (27/12Z TAFS)...

LATEST SURFACE ANALYSIS AND SATELLITE IMAGERY SHOWS MID LEVEL CLOUDS
MOVING NORTH INTO EAST CENTRAL KENTUCKY. ISOLATED TO SCATTERED
SHOWERS WITH AN ISOLATED RUMBLE OF THUNDER WILL DEVELOP NEAR OR JUST
NORTH OF LEX AND SDF. BWG IS EXPECTED TO STAY DRY THROUGH 00Z. ANY
CONVECTION WILL BE DISORGANIZED WITH PERHAPS ONLY A 20 TO 30 PERCENT
CHANCE OF AFFECTING ANY TAF SITES. AFTER 00Z A DISTURBANCE WILL MOVE
NORTH AND WILL POSSIBLY AFFECT THE BLUEGRASS REGION INCLUDING LEX.
HAVE PLACED A VCTS AFTER 21Z FOR LEX.

OTHERWISE...LIGHT WINDS AND VFR CONDITIONS EXPECTED TONIGHT OUTSIDE
OF ANY STRAY SHOWERS OR THUNDERSTORMS. ANY SCATTERED CONVECTION WILL
DIMINISH AFTER 06Z. SOME BROKEN MID-LEVEL CLOUDS ARE POSSIBLE EARLY
TOMORROW WITH ANY CIGS WELL ABOVE 3000 FEET.

AFTERNOON SCATTERED CONVECTION ONCE AGAIN POSSIBLE FRIDAY WITH 30%
OR LESS COVERAGE.
