AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
341 AM EDT SAT MAY 13 2000

A QUIET PERIOD AHEAD WITH LITTLE TO CONTEMPLATE.

NGM AND AVN BEST DEPICT CIRRUS CURRENTLY OVER THE SOUTHEAST PORTION
OF THE FORECAST AREA ASSOCIATED WITH UPPER JET AND TROUGH. BOTH
MODELS INDICATE THE HIGH LEVEL MOISTURE WILL SHIFT FURTHER
SOUTHEAST. SATELLITE DOES SHOW THIS TREND STARTING UPSTREAM OVER
MS/AL CURRENTLY. SO...WILL EXPECT THE HIGH CLOUDS CURRENTLY IN PLACE
TO DEPART FOR SUNDAY. LOWER IN THE ATMOSPHERE...SURFACE AIR MASS IS
SO DRY THAT WITH THE MID LEVEL INVERSION WHICH WILL BE
PRESENT...LITTLE OR NO CU DEVELOPMENT IS EXPECTED TODAY. WILL USE
SUNNY WORDING. NGM MOS TEMPS LOOK GOOD TODAY.

MAINLY CLEAR SKIES CONTINUE TONIGHT. SURFACE HIGH NEARS FROM WEST
WITH LIGHT WINDS. WITH VERY DRY AIR IN PLACE...TEMPS WILL PLUMMET.
THINK THAT SOME VALLEYS WILL DROP BELOW 40 DEGREES. IT IS AWFUL LATE
IN THE SEASON TO TALK ABOUT FROST...BUT DAY SHIFT MAY NEED TO SEE
HOW THINGS PROGRESS BY EVENING AND SEE IF ANY OF OUR MOST SHELTERED
VALLEYS ARE AT RISK.

ON MONDAY WARM AIR ADVECTION IS TAKING PLACE IN MOST AREAS FROM THE
CENTRAL PLAINS TO THE GREAT LAKES. THE AVN SHOWS SOME MID/HIGH
CLOUDS FROM THIS SPILLING INTO EASTERN KY. EVEN IF MID/HIGH CLOUDS
DO NOT MAKE IT THIS FAR SOUTHEAST...ALL MODELS AGREE ON COOLER MID
LEVEL TEMPS ON MONDAY...WHICH WOULD MAKE IT EASIER FOR A FEW CU TO
DEVELOP IN THE AFTERNOON. THUS...WITH MORNING SUNSHINE EXPECTED AND
PROBABLY PARTIAL SUN IN THE AFTERNOON...WILL USE MOSTLY SUNNY
WORDING FOR THE DAY AS A WHOLE. CONSIDERING THE COLD START TO THE
DAY AND TEMPS EXPECTED ALOFT...NGM MOS TEMPS MAY BE A COUPLE DEGREES
TOO WARM ON MONDAY.

.JKL...NONE.
