AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
1020 AM EST TUE MAR 18 1997

LATEST AND GREATEST IS THAT THE SURFACE BOUNDARY CONTINUES TO SLOWLY
SAG SOUTH. THIS HAS RESULTED IN A GOOD BAROCLINIC CONVERGENCE AREA
OVER NRN KY (MESO ANALYSIS-ADAP.) AS THIS SAGS SOUTH THE PRECIP SHIELD
SEEMS TO EXPAND. THE LATEST HOURLY PRECIP SHOWS THE HEAVIEST PCPN
STILL NARROW...WHILE THE 1/2 INCH AMOUNTS AREA IS EXPANDING. THIS HAS
SIGNIFICANT RAMIFICATIONS OVER THE HSA AND FEEL THAT FLASH FLOOD WATCH
IS WARRANTED FOR THIS AFTERNOON AND EVENING.

THE OTHER CONCERN IS THE UPSTREAM JET CORE. THIS SHOULD BE ENOUGH TO
GET THE CONVECTION FIRING SOUTH OF THE STATE. THEN THE SYSTEM WILL
RIDE ALONG THE BAROCLINIC BOUNDARY WITH SIGNIFICANT RAINFALL OVER MUCH
OF EASTERN KENTUCKY LATER TODAY AND EARLY TONIGHT.

OTHER THAN THE FF WATCH...THE GOING FORECAST IS ON TRACK AND NO OTHER
CHANGES NEEDED.

THANKS FOR THE COORD CALL LMK AND HELP FROM LOCAL STAFF.
