AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY

...UPDATED AVIATION DISCUSSION...

.SHORT TERM (NOW THROUGH TUESDAY)...
ISSUED AT 300 AM EDT MON AUG 24 2015

...MUCH COOLER AND DRY WEATHER IN STORE FOR THE WEEK AHEAD...

A STRONG (FOR AUGUST) COLD FRONT IS PUSHING THROUGH THE CWA AT THIS
TIME AND SHOULD EXIT OUR SE AROUND OR JUST AFTER SUNRISE. ISOLATED
SHOWERS AHEAD OF THIS FRONT HAVE DEPARTED, SO EXPECTING A DRY
FORECAST FROM HERE ON. SURFACE HIGH PRESSURE BEGINS TO BUILD IN
TODAY WITH MOSTLY SUNNY SKIES AND A STEADY NW WIND. LOOK FOR MOST
HIGH TEMPS TO RANGE BETWEEN 76-81 ALONG WITH LOW HUMIDITY.

GOOD RADIATIONAL COOLING CONDITIONS WILL OCCUR OVERNIGHT WITH THE
CENTER OF THE CANADIAN HIGH PRESSURE TO OUR WEST. LOOK FOR LOWS TO
DROP INTO THE LOW TO MID 50S IN MOST SPOTS. OUR COOLEST NORTHERN
LOCATIONS MAY SEE LOWS ON EITHER SIDE OF THE 50 DEGREE MARK.

SURFACE HIGH PRESSURE WILL REMAIN IN CONTROL ON TUESDAY WITH
TROUGHING IN CONTROL OF THE EASTERN CONUS. WE`LL STAY DRY WITH
TEMPERATURES A DEGREE OR TWO COOLER THAN MONDAY. THIS WILL GIVE US
READINGS IN THE 74-80 RANGE.

.LONG TERM (TUESDAY NIGHT THROUGH SUNDAY)...
ISSUED AT 258 AM EDT MON AUG 24 2015

HIGH PRESSURE MOVING SLOWLY FROM THE PLAINS TO THE EAST COAST WILL
PROVIDE US WITH DRY AND PLEASANT WEATHER FOR THE REMAINDER OF THE
WORK WEEK. HIGH TEMPERATURES AROUND 80 ON WEDNESDAY AND THURSDAY
WILL WARM INTO THE MID 80S FRIDAY. SUNRISE TEMPERATURES WILL BE IN
THE 50S TO AROUND 60.

THIS WEEKEND THE SURFACE HIGH WILL MOVE OFF TO THE EAST, PUTTING US
IN RETURN FLOW. WEAK UPPER TROFFING WILL BE IN PLACE OVERHEAD. GIVEN
THE PATTERN, WIDELY SCATTERED THUNDERSTORMS CAN`T BE ENTIRELY RULED
OUT. HAVING SAID THAT, THOUGH, PRECIPITABLE WATER VALUES REMAIN
RIGHT AROUND NORMAL WITH DEEP RH ABSENT FROM ATMOSPHERIC CROSS-
SECTIONS. WILL KEEP POPS VERY LOW, IN AGREEMENT WITH SURROUNDING
OFFICES AND PREVIOUS FORECAST. HIGH TEMPERATURES SATURDAY AND SUNDAY
WILL BE IN THE MIDDLE AND UPPER 80S WITH DEW POINTS IN THE 60S.
