AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
245 AM CDT TUE SEP 3 1996

SLOW-MOVING LOW PRES SYSTEM PROMISES TO KEEP A MOIST ENVIRONMENT
(AND A SGFNT RAIN CHC) ACROSS MIDDLE TN TDY. MODELS MOVE SFC TROF
AXIS SLOWLY EWD, AND SHIFT HIGHEST RAIN CHC ONTO THE PLATEAU BY
TONIGHT. BLV 50% POPS FOR WRN COUNTIES AND 60% OR 70% FOR ERN
COUNTIES WUD BE REASONABLE FOR TDY (AS INDICATED BY FAN AND
FWC GUIDANCE) AND THINK CURRENT ZFP TREND OF REDUCING POPS IN 2ND
AND 3RD PDS IS STILL A GUD IDEA.

GUIDANCE TEMPS HAVE BEEN QUITE GUD LAST DAY OR SO AND LOOK VERY
REASONABLE FOR THIS FCST PD. THUS, ZFP TEMPS CONT TO LOOK ON TRACK
AS WELL.

OVERALL, FCST SHUD REQUIRE ONLY MINOR ADJUSTMENTS.@
