AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
348 PM EDT FRI APR 17 2015

.SHORT TERM...(THIS EVENING THROUGH SATURDAY NIGHT)
ISSUED AT 348 PM EDT FRI APR 17 2015

CLOUDS CONTINUE TO SLOWLY BREAK UP THIS AFTERNOON AS HIGH PRESSURE
BUILDS INTO THE OH VALLEY REGION. THIS DRYING SHOULD ALLOW MOST OF
THE REMAINING CLOUDS TO DISSIPATE TONIGHT...WITH THE EXCEPTION OF
THE SOUTHERN COUNTIES WHERE SOME MID LEVEL CLOUDS COULD MOVE IN
DUE A SHORTWAVE MOVING ACROSS THE TN REGION. THAT BEING
SAID...SEEMS LIKE A GOOD SET UP FOR VALLEY FOG
TONIGHT...ESPECIALLY IN AREAS WHERE THERE ARE CLEARER SKIES AND
GOOD RADIATIONAL COOLING. SO WILL MENTION THIS IN THE HWO.

BY SATURDAY...A CLOSED UPPER LOW EJECTS INTO THE CENTRAL
PLAINS...AND A SHORTWAVE MOVES OUT OF THE BASE OF THE
LOW...CROSSING THE LOWER MS RIVER VALLEY AND NORTHEAST INTO THE OH
AND TN VALLEYS. SURFACE LOW PRESSURE AND A DEVELOPING WARM FRONT
WILL BRING A SURGE OF MOIST AIR INTO EAST KENTUCKY WITH SLIGHT
CHANCE POPS MAKING IT INTO POINTS SOUTH OF THE HAL ROGERS PARKWAY
BY SATURDAY AFTERNOON. HOWEVER...PRECIP WILL HOLD OFF LONG ENOUGH
FOR YOU TO ENJOY A WARM AND SUNNY DAY WITH TEMPERATURES REACHING
THE 80 DEGREE MARK IN MOST LOCATIONS. THE BEST CHANCE FOR
MEASUREABLE PRECIP WILL BE AFTER 06Z SUNDAY.

.LONG TERM...(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 348 PM EDT FRI APR 17 2015

THE LONG TERM DISCUSSION WILL BE ISSUED SHORTLY.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)
ISSUED AT 155 PM EDT FRI APR 17 2015

LOW LEVEL CLOUDS HAVE HAD A HARD TIME BREAKING UP THIS AFTERNOON.
BUT GIVEN RECENT VIS IMAGERY TRENDS...EXPECT MUCH OF THE
REMAINING CLOUD COVER TO CONTINUE BREAKING UP AND CIGS TO IMPROVE
TO VFR THROUGHOUT THE REMAINDER OF THE AFTERNOON. HIGH PRESSURE
MOVING IN LATER THIS EVENING AND TONIGHT ALONG WITH LIGHT WINDS
WILL PROVIDE AN ENVIRONMENT FAVORABLE FOR FOG DEVELOPMENT AND SO
HAVE PUT IFR VIS IN THE LOZ...JKL...SJS...SYM TAF SITES AND
ALTERNATE MINS AT THE SME TAF SITE TONIGHT AFTER 06Z. CONDITIONS
SHOULD THEN IMPROVE TO VFR ACROSS ALL TAF SITES AROUND 13Z.
