AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
300 PM EDT TUE AUG 8 2000

PREVIOUS ZONE PACKAGE ON THE RIGHT TRACK AND WILL BE KEPT FOR MOST
PART.

MODELS IN GENERAL AGREEMENT ALTHOUGH THE MESO ETA IS THE ODD MODEL
OUT AT THIS TIME. COMPARING THE MODEL TO THE RADAR/SATELLITE AND
CURRENT PRECIPITATION ANALYSIS THE ETA IS CLOSEST WITH THE NGM A
CLOSE SECOND. WITH THAT IN MIND AND GIVEN THE PAST PERFORMANCE OF
THE MODELS...WILL NOT ARGUE WITH MOS AND KEEP NUMBERS DARN CLOSE.
MOST LIKELY WILL OPT FOR SIMILAR POPS...BUT MAY SHAVE THE MAX TEMPS
DOWN ABOUT 5 DEGREES.

IN THE MEANTIME THE SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
DOMINATE THE PATTERN. THESE MESOSCALE FEATURES WILL BE TOUGH TO
FORECAST AND WILL MAKE WORDING IN ZONES REFLECT THE TREND. NOT MUCH
CHANGE THROUGH 60 HOURS AS THE RIDGE AMPLIFIES AND WE STAY IN
CYCLONIC FLOW PATTERN. THIS IS GOOD FOR MADDOX TYPE RAIN EVENTS AND
WILL LIKELY POST A FLASH FLOOD WATCH OVER MUCH OF THE CWA FOR
