AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
1249 AM EDT THU AUG 27 2015

...UPDATED AVIATION DISCUSSION...

.SHORT TERM (NOW THROUGH THURSDAY NIGHT)...
ISSUED AT 339 PM EDT WED AUG 26 2015

TRANQUIL FALL LIKE WEATHER WILL CONTINUE ACROSS THE REGION IN THE
SHORT TERM PERIOD.  LARGE AREA OF HIGH PRESSURE OVER THE SOUTHERN
GREAT LAKES AND NORTHERN OHIO VALLEY WILL CONTINUE TO HOLD SWAY
DURING THE PERIOD.  DIURNAL CUMULUS FIELD WILL DISSIPATE THIS
EVENING WITH SKIES RETURNING TO A MOSTLY CLEAR STATE.  EVENING
TEMPERATURES WILL FALL INTO THE UPPER 60S TO THE LOWER 70S BEFORE
BOTTOMING OUT OVERNIGHT IN THE LOWER-MID 50S.  A FEW MORE UPPER 40S
WILL BE POSSIBLE IN OUR TYPICAL COLDER LOCATIONS.  WE DO EXPECT A
LITTLE BIT OF RIVER VALLEY FOG AGAIN OVERNIGHT, MAINLY ACROSS
SOUTHERN/EAST-CENTRAL KY.

FOR THURSDAY AND THURSDAY NIGHT, WE SHOULD START OFF MOSTLY SUNNY IN
THE MORNING HOURS.  HOWEVER, ANOTHER DIURNAL CUMULUS FIELD WILL
LIKELY DEVELOP BY LATE MORNING AND PERSIST INTO THE AFTERNOON HOURS,
YIELDING PARTLY CLOUDY CONDITIONS. AFTERNOON HIGHS WILL LIKELY TOP
OUT IN THE MID-UPPER 70S AGAIN ACROSS THE NORTH WITH UPPER 70S TO
NEAR 80 ACROSS THE SOUTH.  LOWS THURSDAY NIGHT DO NOT LOOK TO BE AS
COOL WITH MID-UPPER 50S ACROSS THE NORTH AND UPPER 50S ACROSS THE
SOUTH.

.LONG TERM (FRIDAY THROUGH WEDNESDAY)...
ISSUED AT 258 PM EDT WED AUG 26 2015

SURFACE HIGH PRESSURE WILL BE MOVING OFF TO THE EAST ON FRIDAY. THE
NEXT TROUGH AND SURFACE LOW ACROSS THE MIDWEST AT THE START OF THE
PERIOD WILL SLOWLY MOVE EAST ACROSS THE GREAT LAKES REGION THROUGH
THE WEEKEND. MEANWHILE ANOTHER WEAK SYSTEM WILL BRING MOISTURE IN
FROM THE SOUTH.

FRIDAY LOOKS TO REMAIN DRY AS THE HIGH PRESSURE DEPARTS TO THE EAST.
WE WILL SEE SOME WARMING FRIDAY WITH HIGHS REACHING INTO THE MID
80S. THERE WILL BE SOME SLIGHT CHANCES FOR RAIN AND STORMS FROM BOTH
THE SYSTEM TO THE NORTH AND THE ONE TO THE SOUTH ACROSS THE FORECAST
AREA THIS WEEKEND. PORTIONS OF THE REGION COULD LAND IN BETWEEN
THESE TWO SYSTEMS AND THUS STAY DRY, HOWEVER.

RAIN CHANCES FOR MONDAY AND TUESDAY BECOME A BIT MORE QUESTIONABLE
AS RIDGING BUILDS ACROSS THE REGION, SO WILL KEEP THE FORECAST DRY
FOR NOW.

TEMPERATURES THROUGH THE MAJORITY OF THE LONG TERM PERIOD WILL BE
NEAR NORMAL FOR THIS TIME OF YEAR. HIGHS WILL BE IN THE MID TO UPPER
80S WITH LOWS IN THE MID 60S TO AROUND 70.

WELL...ACROSS THE REGION ARE SOME FEW TO SCT 060 CUMULUS CLOUDS FROM
CVG TO GLW. 1022 MB HIGH PRESSURE NEAR ORD/MDW WILL MOVE TO ERI.
THIS WILL BRING LIGHT NELY WINDS TO ENE TODAY LESS THAN 10 KTS.
THIS HIGH PRESSURE WILL CONTINUE TO BRING FABULOUS VFR CONDITIONS
THROUGH THE PERIOD.

WITH DEW POINTS IN THE MID 50S, COULD BE MIFG FOG AT KBWG OR PERHAPS
KLEX. BWG WAS ERRATIC JUST BEFORE SUNRISE WEDNESDAY MORNING AND THEY
HIT CROSSOVER TEMPERATURE TODAY SO HAVE A TEMPORARY 2 HOUR MVFR
