AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
330 PM EDT FRI AUG 28 2015

.SHORT TERM...(THIS EVENING THROUGH SATURDAY NIGHT)
ISSUED AT 330 PM EDT FRI AUG 28 2015

MODELS ARE IN GOOD AGREEMENT THROUGH THE SHORT TERM. APPROACHING
SHORTWAVE AND RETURN MOISTURE FROM THE SOUTH WILL GRADUALLY
INCREASE THE THREAT FOR SOME SHOWER OR THUNDERSTORM ACTIVITY
THROUGH THE DAY SATURDAY INTO EARLY SATURDAY EVENING. EXPECT ANY
ACTIVITY THAT DOES MANAGE TO DEVELOP TO BE ISOLD AND DIURNALLY
DRIVEN...DISSIPATING BY AROUND SUNSET. THE POTENTIAL FOR RAIN
INCREASES AGAIN TOWARDS DAWN SUNDAY AS THE SHORTWAVE TROUGH GETS
CLOSER TO OUR AREA. TEMPERATURES WILL CONTINUE TO MODERATE TO NEAR
NORMAL LEVELS. DEW POINTS WILL ALSO RISE...MAKING IT FEEL LESS
COMFORTABLE THAN THE PREVIOUS FEW DAYS.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 308 PM EDT FRI AUG 28 2015

OUR FORECAST IS A TAD BIT MUDDLED AS THE AREA LIES IN BETWEEN TWO
UPPER LEVEL RIDGE CORES...ONE LOCATED OVER THE FOUR CORNERS REGION
AND THE OTHER OVER THE WESTERN ATLANTIC. WEAK SHORTWAVES IN
BETWEEN THESE RIDGE CORES WILL AFFECT US THROUGH TIME. MOISTURE
WILL BE ON THE INCREASE AS WELL AS SOUTHWEST FLOW AROUND THE RIDGE
CORE TO OUR EAST TAPS INTO SOME TROPICAL MOISTURE...INCLUDING
POTENTIALLY SOME MOISTURE FROM WHAT IS NOW TROPICAL STORM ERIKA
LATE IN THE PERIOD.

SENSIBLE WEATHER WILL FEATURE THE THREAT FOR SCATTERED SHOWERS
AND STORMS SUNDAY INTO MONDAY AS A WEAK UPPER LEVEL LOW NOW
LOCATED OVER THE NORTHERN GULF SHIFTS NORTHEAST ACROSS OUR REGION.
ONCE THIS PASSES...THE THREAT FOR RAIN DIMINISHES WITH PERHAPS AN
AFTERNOON SHOWER OR STORM POSSIBLE OVER OUR HIGHER TERRAIN ALONG
THE VIRGINIA AND TENNESSEE BORDERS TUESDAY AND WEDNESDAY. RAIN
CHANCES...ALBEIT LOW...WILL THEN CREEP BACK INTO THE FORECAST
THURSDAY AND FRIDAY AS MODELS INDICATE A REINFORCING SHOT OF
MOISTURE MOVING BACK NORTH INTO THE AREA PERHAPS ASSOCIATED WITH
ERIKA...ALTHOUGH THERE IS NOT REAL CONSENSUS ON WHERE THAT SYSTEM
WILL BE BY THAT FAR OUT IN TIME.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)

TO SEEP BACK INTO THE AREA. WINDS WILL BE LIGHT AND VARIABLE
