AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
709 PM EDT SAT SEP 10 2011

...UPDATED AVIATION DISCUSSION...

.SHORT TERM (TONIGHT AND SUNDAY)...

SPRAWLING CUTOFF LOW CENTERED OVER THE MID MS RIVER VALLEY IS JUST
ABOUT READY TO OPEN UP AND KICK OFF TO THE EAST...WHICH SHOULD OCCUR
ON SUNDAY. VISIBLE IMAGERY TODAY INDICATES A BROAD CIRCULATION IN
THE LOW-LEVEL CLOUDS...CENTERED ROUGHLY OVER THE IL/IN SOUTHERN
BORDER. CONGESTED CU FIELD DEVELOPING EAST OF THIS CENTER IS WHERE
SHOWERS ARE FORMING SO FAR THIS AFTERNOON. LAPS AND LOCAL AMDAR
SOUNDINGS INDICATE SOME A SLIVER OF CAPE...WITH VALUES UNDER 1000
J/KG...IN THIS AREA SO CANNOT RULE OUT SOME STORM DEVELOPMENT WITH
PEAK HEATING. BY EVENING SHOULD ONLY SEE SHOWERY ACTIVITY...PERHAPS
STICKING AROUND TO MIDNIGHT.

LOWS TONIGHT SHOULD BE A LITTLE WARMER THAN THIS MORNING...WITH
VALUES IN THE LOWER 60S FOR THE LOUISVILLE METRO AND AROUND 60
ELSEWHERE.

SUNDAY THAT ABOVE-MENTIONED UPPER LOW WILL OPEN UP AND MOVE SLOWLY
EAST AS ANOTHER TROUGH CONNECTS WITH IT AS IT MOVES OVER THE
NORTHERN GREAT LAKES. GIVEN THE CLOSER PROXIMITY TO COOL
TEMPERATURES ALOFT AND LIKELIHOOD OF HIGH TEMPERATURES SIMILAR TO
TODAY...WOULD COVERAGE OF SHOWERS/STORMS TO BE A LITTLE HIGHER. HAVE
GONE 40-50 PERCENT ACROSS THE NORTHERN FORECAST AREA AND LOW-END
SCATTERED ACROSS THE SOUTH. CAPE/S ARE A LITTLE HIGHER AS WELL...SO
STORMS MAY HAVE SLIGHTLY STRONGER WINDS AND AGAIN SOME POTENTIAL FOR
SMALL HAIL...AS MENTIONED IN PREVIOUS LONG TERM DISCUSSION. STILL
THREAT FOR SEVERE WEATHER LOOKS LOW.

.LONG TERM (SUNDAY NIGHT - SATURDAY)...

THE UPPER LEVEL TROUGH WILL FINALLY MOVE EAST OF THE AREA OVERNIGHT
SUNDAY NIGHT INTO MONDAY. THERE MAY BE SOME ISOLATED SHOWERS AND
THUNDERSTORMS ONGOING ON SUNDAY EVENING OVER EAST CENTRAL KENTUCKY.
THESE ARE EXPECTED TO END BEFORE MIDNIGHT. CLOUDS WILL BEGIN TO
BREAK UP DURING THE OVERNIGHT HOURS WITH LOWS EXPECTED TO BE IN THE
UPPER 50S TO LOWER 60S.

MONDAY THROUGH TUESDAY WILL BE WARMER AND DRIER ACROSS THE AREA.
WINDS WILL BE OUT OF THE SOUTHWEST WITH PARTLY CLOUDY SKIES. THESE
SOUTHERLY WINDS WILL PICK UP ON TUESDAY AS A COLD FRONT APPROACHES
FROM THE NORTHWEST. HIGHS ON MONDAY WILL REACH INTO THE LOW 80S.
TUESDAY LOOKS TO BE THE WARMEST DAY OF THE PERIOD WITH HIGHS TOPPING
OUT IN THE MID 80S ACROSS THE REGION. LOWS WILL BE IN THE LOW TO MID
60S.

TUESDAY NIGHT THROUGH THE END OF THE WEEK A LARGE AREA OF SURFACE
HIGH PRESSURE WILL BUILD ACROSS THE GREAT LAKES. THE LOWER OHIO
VALLEY WILL SIT ON THE SOUTHERN EDGE OF THIS HIGH BY THE LATTER HALF
OF THE WEEK. THE AFOREMENTIONED COLD FRONT WILL MOVE THROUGH THE
FORECAST AREA OVERNIGHT TUESDAY NIGHT INTO WEDNESDAY MORNING. WHILE
WIDESPREAD THUNDERSTORMS ARE NOT EXPECTED TO ACCOMPANY THIS FRONT WE
COULD SEE A FEW DURING THE OVERNIGHT HOURS WITH A SLIGHT
CHANCE FOR SHOWERS CONTINUING THROUGH THE DAY WEDNESDAY. A
REINFORCING WAVE WILL MOVE THROUGH ON THURSDAY WITH A CONTINUED
CHANCE FOR SHOWERS THROUGH THURSDAY NIGHT. BEHIND THE INITIAL FRONT
INSTABILITY LOOKS TO BE PRETTY MEAGER. THOUGH AN ISOLATED
THUNDERSTORM CANNOT BE COMPLETELY RULED OUT THURSDAY...WILL MENTION
ONLY SHOWERS AT THIS TIME. TIMING OF THE FRONT AND REINFORCING WAVE IS
STILL A BIT IN QUESTION AND COVERAGE OF SHOWERS/STORMS THROUGH THE
LATTER HALF OF THE WORK WEEK WILL NEED TO BE REFINED IN LATER
FORECASTS.

COOLER AIR WILL SETTLE INTO THE REGION ONCE AGAIN WEDNESDAY THROUGH
FRIDAY. HIGHS WEDNESDAY WILL BE IN THE MID 70S WHILE THURSDAY AND
FRIDAY LOOK TO REACH ONLY INTO THE LOW TO MID 70S. LOWS WILL DROP
FROM THE MID 50S MIDWEEK TO THE LOW 50S BY THE END OF THE WEEK.

&&

.AVIATION (00Z TAF ISSUANCE)...

SCATTERED SHRA/TSRA HAVE DEVELOPED MAINLY ACROSS W-CENTRAL AND
S-CENTRAL KY THIS AFTERNOON...AFFECTING THE BWG TERMINAL AT THE
MOMENT. WILL KEEP IN VCTS THERE AND A TEMPO FOR BRIEF VSBY/CIG
REDUCTIONS AT BWG AS WELL AS WIND GUSTS FROM STORM OUTFLOW. SDF MAY
SEE A SHRA/TSRA WITHIN THE NEXT 1-2 HOURS BUT LEX SHOULD BE PRECIP
FREE. MAY KEEP A VCSH THERE IN CASE A STRAY SHOWER MOVES FURTHER
EAST THAN EXPECTED. MOST IF NOT ALL ACTIVITY SHOULD DISSIPATE
QUICKLY AFTER SUNSET.

THEREAFTER...BREAKS IN THE CLOUDS AND LIGHT WINDS WILL ALLOW FOR
GOOD RADIATIONAL COOLING IN SPOTS TOWARDS 12Z SUNDAY. BWG WILL MOST
LIKELY HAVE THE LOWEST VSBY REDUCTION FROM BR/LIGHT FG SO WILL HAVE
A PREVAILING MVFR VSBY THERE AND POSSIBLY A TEMPO OF IFR-LIFR. MORE
LATE MORNING AND EARLY AFTERNOON CU AND SCATTERED SHRA/TSRA SHOULD
REDEVELOP TOMORROW TOWARDS THE END OF THIS TAF PERIOD.
