AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
225 PM CDT FRI MAY 17 2002

MID AFTERNOON SURFACE MAP SHOWS COLD FRONT ALONG OHIO VALLEY...THEN
DROPPING ACROSS AR INTO NORTH TX. MOVEMENT HAS BEEN SLOWER THAN WE
EXPECTED YESTERDAY. LOW PRESSURE OVER AR WILL SLIDE NORTHEAST TO
EAST KY BY LATE EVENING. THIS WILL ACCELERATE THE FRONT ACROSS OUR
FORECAST AREA THIS EVENING. ESTIMATED FRONTAL PASSAGE FOR CKV AROUND
00Z...BNA AROUND 02Z...AND CSV AND TULLAHOMA BY MIDNIGHT. BANDS OF
THUNDERSTORMS AHEAD OF FRONT WILL CONTAIN SOME HEAVY RAINFALL...
GUSTY WINDS AND HAIL. IN FACT SEVERAL HAIL REPORTS HAVE ALREADY BEEN
RECEIVED.

STILL HAVE A FLOOD WATCH FOR NORTHWEST COUNTIES UNTIL MIDNIGHT. IT
APPEARS THAT THE HEAVIEST RAIN WILL BE OUT OF THAT AREA EARLY THIS
EVENING. DO NOT WANT TO TINKER WITH FFA FOR NOW WHILE SOME HEAVY
RAINFALL STILL OCCURRING. FFA MAY BE DROPPED AT LAST MINUTE BEFORE
ZONE ISSUANCE...BUT MORE LIKELY EVENING SHIFT WILL DO AN EARLY
CANCELLATION. ISOLATED FLOODING POSSIBLE REST OF FORECAST AREA WITH
HEAVY THUNDERSTORMS...GENERALLY ISOLATED URBAN AND SMALL STREAM
PROBLEMS. TRAINING WAS A PROBLEM IN NORTHWEST COUNTIES AND
ESPECIALLY WEST KENTUCKY EARLY MORNING...BUT TRAINING WILL NOT BE AS
MUCH OF A PROBLEM THIS EVENING WITH ACCELERATING WEATHER SYSTEM.

MODELS AGREE WITH BRINGING SIGNIFICANTLY COOLER CONDITIONS THIS
WEEKEND. DEEP MID AND UPPER LEVEL TROUGH OVER THE EASTERN STATES
WILL PROVIDE WELL BELOW NORMAL TEMPERATURES. SOME WEAK DISTURBANCES
AND POCKETS OF MOISTURE INDICATED BY THE AVN MODEL SUGGEST THE
POSSIBILITY FOR A FEW PERIODS OF CLOUDS OVER THE NEXT FEW DAYS.
MOS NUMBERS GIVE AROUND 42 FOR BNA SATURDAY NIGHT. SINCE THIS IS
MORE THAN 15 BELOW NORMAL WILL GO WITH COLD WORDING IN ZONE
FORECAST.

THROUGH THE REST OF THE FORECAST PERIOD...A LARGE SURFACE HIGH FROM
CANADA WILL SLIDE ACROSS THE MIDWEST TO THE MID ATLANTIC REGION BY
MIDWEEK. THIS SPRAWLING HIGH WILL GIVE US FAIR WEATHER WITH A
GRADUAL AND VERY PLEASANT WARMING TREND THROUGH NEXT WEEK.
