AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
1235 AM EDT WED AUG 26 2015

...UPDATED AVIATION DISCUSSION...

.SHORT TERM (NOW THROUGH WEDNESDAY NIGHT)...
ISSUED AT 300 PM EDT TUE AUG 25 2015

TRANQUIL WEATHER IS FORECAST TO CONTINUE OVER THE SHORT TERM PERIOD.
LARGE AREA OF CANADIAN HIGH PRESSURE WILL DRIFT FROM THE PLAINS AND
INTO THE GREAT LAKES AND OHIO VALLEY OVER THE NEXT 24-36 HOURS.
OTHER THAN SOME DIURNALLY DRIVEN CU, SKIES SHOULD GENERALLY REMAIN
MOSTLY CLEAR THROUGHOUT THE PERIOD.  AFTER HIGHS THIS AFTERNOON IN
THE MID-UPPER 70S, TEMPERATURES BY LATE EVENING WILL DROP INTO THE
UPPER 50S TO THE LOWER 60S.

OVERNIGHT, MOSTLY CLEAR SKIES ARE EXPECTED.  WE ARE LIKELY TO SEE
VALLEY FOG DEVELOP ONCE AGAIN.  WIDESPREAD FOG DEVELOPMENT DOES NOT
LOOK LIKELY DUE TO RATHER LIMITED MOISTURE IN THE COLUMN.  OVERNIGHT
LOWS WILL LIKELY DROP INTO THE LOW-MID 50S IN MOST AREAS. A FEW OF
OUR COOLER SPOTS WILL LIKELY REACH THE UPPER 40S ONCE AGAIN.  URBAN
AREAS WILL REMAIN THE WARMEST WITH MID-UPPER 50S.

TRANQUIL WEATHER WILL CONTINUE INTO WEDNESDAY AND WEDNESDAY NIGHT AS
WE REMAIN UNDER THE INFLUENCE OF HIGH PRESSURE.  HIGHS WEDNESDAY MAY
BE SLIGHTLY WARMER THAN TODAY WITH READINGS GENERALLY IN THE MID-
UPPER 70S, THOUGH SOME LOW 80S WILL BE POSSIBLE ACROSS SOUTHERN KY.
LOWS WEDNESDAY NIGHT DO NOT LOOK TO COOL AS MUCH AS THE PREVIOUS FEW
NIGHTS WITH READINGS LIKELY TO DROP INTO THE MID-UPPER 50S.

.LONG TERM (THURSDAY THROUGH TUESDAY)...
ISSUED AT 247 AM EDT TUE AUG 25 2015

THE BROAD TROUGH ACROSS THE EASTERN CONUS WILL SHIFT EASTWARD
THURSDAY AND FLOW ALOFT WILL BECOME MORE ZONAL FRIDAY INTO SATURDAY
MORNING. DRY CONDITIONS WILL PERSIST THURSDAY AND FRIDAY. WE WILL
START TO SEE A WARM UP INTO THE WEEKEND. WHILE HIGHS WILL TOP OUT IN
THE UPPER 70S TO AROUND 80 ON THURSDAY, MOST LOCATIONS SHOULD REACH
THE LOWER 80S FRIDAY.

A SHORTWAVE TROUGH WILL APPROACH AND SLOWLY MOVE ACROSS THE REGION
THIS WEEKEND. WE WILL HAVE SOME MODEST MOISTURE RETURN TO THE AREA
AND SOUTHERLY WINDS WILL BRING TEMPERATURES BACK TOWARDS NORMAL FOR
THIS TIME OF YEAR. MODELS CONTINUE TO SUGGEST ISOLATED TO POSSIBLY
SCATTERED STORMS COULD DEVELOP DURING THIS TIME FRAME, THOUGH
CONFIDENCE IN PLACEMENT CONTINUES TO BE LOW. WILL LIMIT POPS TO
SLIGHT CHANCE FOR NOW GIVEN THE LOW CONFIDENCE IN COVERAGE AND
PLACEMENT. AS MENTIONED ABOVE, TEMPERATURES WILL BE NEARER TO NORMAL
FOR THIS TIME OF YEAR WITH HIGHS IN THE MID TO UPPER 80S AND LOWS IN
THE MID TO UPPER 60S.

.AVIATION (06Z TAF UPDATE)...
ISSUED AT 1235 AM EDT WED AUG 26 2015

HIGH PRESSURE WILL CONTINUE TO PROVIDE US WITH QUIET WEATHER. THERE
IS A POSSIBILITY OF SOME BRIEF 4SM BR AT LEX AND BWG IN THE 10Z-12Z
TIME FRAME, BUT CHANCES ARE LOW ENOUGH THAT THE TAFS WILL REMAIN VFR
FOR NOW. WILL KEEP AN EYE ON VSBY TRENDS FOR ANY NECESSARY
AMENDMENTS.
