AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
115 PM CST FRI MAR 28 1997

MAIN CONCERN IS THUNDERSTORM DEVELOPMENT.

18Z SURFACE MAP SHOWED FRONT FROM JUST WEST OF STL TO TXK.  FRONT WAS
MOVING A BIT FASTER THAN PROGGED AND COULD BE NEAR CGI BY 3 PM AND PAH
BY 4-5 PM.  DEEPEST MOISTURE/THETAE RIDGE REMAINS ACROSS CENTRAL KY AND
FEELING HERE IS THAT STORMS WILL WAIT UNTIL THEY HIT THE BETTER MOISTR
AXIS BEFORE BECOMING SIGNIFICANT.  UNTIL THEN COULD SEE SCT TO BKN LINE
OF STORMS ALONG COLD FRONT AS IT APPROACHES MS RVR.  WITH STRONG WIND
FIELDS AND LOWERING WET BULB ZERO HEIGHTS WOULD THINK MAIN EMPHASIS
WOULD BE ISOLATED WIND AND HAIL AT ONSET.  THINK FRONT WILL REACH EAST
OF THE PADUCAH FORECAST AREA BY 9 PM.  WILL NEED MENTION OF STORMS FOR
JUST ABOUT ALL BUT SEMO ZONES THIS EVENING.

FWC AND FAN SIMILAR ON TONIGHTS LOWS AND WILL ACCEPT.  FAN A BIT HIGHER
SATURDAY BUT CUTTING DIFFERENCE GIVES 60-65 FOR SOUTHERN HALF OF FA
AND AROUND 60 NORTHERN SECTIONS.
.
LOOKS LIKE NEXT COLD FRONT ARRIVING SATURDAY NIGHT WILL BE MOISTURE
STARVED AND SHOULD ONLY BE A FEW CLOUDS...SETTING UP BEAUTIFUL EASTER
SUNDAY.
