AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
308 PM EDT WED AUG 19 2015

.SHORT TERM (NOW THROUGH THURSDAY NIGHT)...
ISSUED AT 300 PM EDT WED AUG 19 2015

A SLOW MOVING COLD FRONT WILL APPROACH THE REGION THIS EVENING AND
PASS THROUGH THE REGION LATE TONIGHT INTO TOMORROW MORNING.  ROUNDS
OF SHOWERS/STORMS WILL CONTINUE AHEAD OF THIS FRONT.  MODELS AND
DOWNSTREAM OBS INDICATE A WIDESPREAD ROUND OF CONVECTION FOR LATE
THIS AFTERNOON/EVENING AND ANOTHER FOR LATE TONIGHT RIGHT BEFORE
FROPA.  STORM CHANCES LOOK TO BE GREATEST IN CONVECTION LATE THIS
AFTERNOON AND EVENING WITH THE GREATEST INSTABILITY EXPECTED DURING
THIS TIME FRAME.  SOUNDINGS ARE PRETTY MOIST ALL THE WAY UP THE
COLUMN WHICH MAY HELP LIMIT ANY WIND THREAT.  HOWEVER, PRECIP
LOADING MAY PRODUCE SOME STRONG TO PERHAPS ISLD INSTANCES OF
DAMAGING WINDS. SOUTH CENTRAL AND EAST CENTRAL KY PERHAPS STAND THE
BEST CHANCE AT SEEING THE STRONGEST STORMS AS THEY RECEIVED LESS
RAINFALL THIS MORNING LEAVING THE ATMOSPHERE LESS WORKED OVER. ALSO
MINOR FLOODING MAY BECOME A CONCERN ESPECIALLY IN AREAS THAT SEE
REPEATED STORMS.  THERE WAS ONE FLASH FLOOD REPORT OUT OF WESTERN KY
ALREADY THIS AFTERNOON.

THE SECOND ROUND OF STORMS LATE TONIGHT MAY BE MORE RAIN THAN
THUNDERSTORMS BUT ELEVATED ISLD T-STORMS WILL STILL BE POSSIBLE
UNTIL THE FRONT PASSES THROUGH LATE TONIGHT INTO THE MORNING HOURS
THURSDAY. STEADY RAINS SHOULD COME TO AN END AFTER THE FROPA.  A FEW
LINGERING SHOWERS IN LOW CLOUDS MAY STICK AROUND AFTER SUNRISE, BUT
MOST LOCATIONS SHOULD BE DRY BY TOMORROW AFTERNOON.

SFC HIGH PRESSURE WILL SETTLE IN FOR TOMORROW NIGHT WITH SOME PATCHY
VALLEY FOG POSSIBLE.

LOW TEMPERATURES TONIGHT WILL DEPEND ON THE COLD FRONT PROGRESSION
EASTWARD.  GENERALLY LOWS SHOULD RANGE FROM THE UPPER 50S TO UPPER
60S WITH EAST CENTRAL KY BEING THE WARMEST.  TOMORROW'S HIGH TEMPS
SHOULD REACH THE UPPER 70S/LOWER 80S AS SKIES CLEAR OUT IN THE
AFTERNOON HELPING HEATING.  THUR NIGHT'S LOWS SHOULD RANGE FROM THE
MID 50S TO AROUND 60.

.LONG TERM (FRIDAY THROUGH WEDNESDAY)...
ISSUED AT 200 PM EDT WED AUG 18 2015

THE MAIN FORECAST CONCERN IN THE LONG TERM IS PRECIPITATION CHANCES
SUNDAY NIGHT - MONDAY. OTHERWISE, DRY CONDITIONS, LOWER HUMIDITY AND
COOLER TEMPERATURES LOOK TO BE THE MAIN STORY.

COOL CANADIAN HIGH PRESSURE IS EXPECTED TO ENCOMPASS MUCH OF THE
LOWER GREAT LAKES DOWN INTO THE TENNESSEE VALLEY FRIDAY THROUGH AT
LEAST SUNDAY MORNING. THIS WILL PROVIDE SEVERAL DAYS OF LOWER
HUMIDITY CHARACTERIZED BY PWATS IN THE 0.5 TO 0.75 INCH RANGE
/1 TO 2 SD BELOW NORMAL/ AND AFTERNOON DEWPOINTS IN THE 50S. PLAN ON
HIGHS A COUPLE OF DEGREES EITHER SIDE OF 80 ON FRIDAY...THEN LOW/MID
80S SATURDAY AND SUNDAY. MORNING LOWS WILL BE QUITE
REFRESHING...MID/UPPER 50S FRIDAY THEN UPPER 50S TO LOW 60S FOR THE
WEEKEND.

BY SUNDAY...AN UPPER LEVEL SHORTWAVE TROUGH DROPS TOWARD THE GREAT
LAKES WITH THE BULK OF THE DYNAMICS STAYING TO THE NORTH AS IT
SWINGS THROUGH. AT THE SURFACE...A WEAKENING COLD FRONT WILL PASS BY
EITHER LATE SUNDAY NIGHT OR MONDAY MORNING. AT THIS TIME...A LACK OF
STRONG MOISTURE RETURN ON THE BACKSIDE OF THE DEPARTING SURFACE HIGH
AND LIMITED FORCING ALONG THE FRONT WOULD MAKE FOR ISOLATED TO
SCATTERED SHOWERS/STORMS. A MULTI-MODEL CONSENSUS OF 20-30 PERCENT
CHANCES LOOKS REASONABLE.

IN THE WAKE OF THAT SYSTEM...A REINFORCING PUSH OF COOLER AND DRIER
AIR LOOKS LIKELY. THIS WOULD GIVE SOUTHERN INDIANA AND CENTRAL
KENTUCKY ANOTHER REFRESHING EARLY TASTE OF FALL WEATHER
CHARACTERIZED BY MORNING LOWS IN THE 50S AND HIGHS IN THE UPPER 70S
TO LOWER 80S.

&&

.AVIATION (18Z TAF UPDATE)...
ISSUED AT 130 PM EDT WED AUG 19 2015

A SLOW MOVING FRONT WILL APPROACH THE REGION TODAY AND PASS THROUGH
THE REGION LATE TONIGHT INTO THURS MORNING.  MULTIPLE ROUNDS OF
CONVECTION ARE EXPECTED AHEAD OF THIS FRONT.  THE BEST CHANCE FOR
SHOWERS AND SCATTERED TO NUMEROUS STORMS WILL BE LATE AFTERNOON
THROUGH THIS EVENING AND HAVE HIGHLIGHTED THIS PERIOD IN THE TAFS
WITH MORE TS MENTION.  BWG AND MAYBE EVEN LEX COULD EXPERIENCE
STRONG STORMS WITH IFR CONDITIONS AND GUSTY WINDS.  AFTER THE
EVENING ROUND OF CONVECTION A SECOND ROUND IS EXPECTED LATE TONIGHT
JUST AHEAD OF THE FRONT.  THINK THAT THIS LATER ROUND WILL BE MAINLY
SHOWERS WITH PERHAPS SOME EMBEDDED ISLD TS.  WASN'T CONFIDENT IN T-
STORM CHANCES LATE TONIGHT WITH THE SECOND ROUND SO WENT WITH -SHRA
IN THE TAFS.  THE FROPA SHOULD OCCUR AROUND 9-12Z ACROSS THE TAF
SITES ENDING CONVECTION.  LINGERING MVFR (POSSIBLY LOWER) SHOULD
LINGER THROUGH A PORTION OF THE MORNING HOURS BEFORE SCATTERING OUT.
WINDS WILL VEER FROM SSW TO SW THIS EVENING AND THEN TURN MAINLY
WESTERLY POST-FRONT.
