Area forecast discussion, Jul 8, 2:15 PM CDT, 5 hours 50 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
115 PM CST TUE JUL 8 1997

BIG CONCERN TODAY IS MCS INDUCED CIRCULATION CENTER MOVING ACROSS
MISSOURI AND THE PREVIOUS BOUNDARIES/GRAVITY WAVES ET AL OUT AHEAD
OF IT.  THUNDERSTORMS ADDED TO TODAYS FORECAST BUT WILL PROBABLY
REMAIN ISOLATED TO WIDELY SCATTERED IN COVERAGE.  MOST OF THIS
SHOULD DIE WITH SUNSET...BUT QUESTION REMAINS AS TO WHERE NEXT
SYSTEM WILL FORM OVERNIGHT AND WHAT FRONT WILL DO WEDNESDAY.

PREFER ETA VERSION OF TAKING MOST QPF INTO SOUTHERN ARK TODAY
AS COMPLEX DEVELOPS IN AREA OF BEST INSTABILITY/MOISTURE INDUCED
BY OUTFLOWS FROM MCS.  NGM HINTING THAT ANOTHER MCS MAY FORM IN
MISSOURI OVERNIGHT BUT INFLOW MAY BE INTERRUPTED BY ARK ACTIVITY
THEREFORE WILL PUT MORE WEIGHT IN ETA ATTM.  WILL SUGGEST MAINTAINING
THE CHANCE POPS THROUGH WEDNESDAY.  COLD FRONT SLOWLY SAGS TOWARD
THIS AREA AND REAL DRY AIR MAY WAIT UNTIL HEIGHTS LOWER LATER IN WEEK
TO GET THIS FAR SOUTH.  THEREFORE PREFER A GRADUAL COOLING TREND MUCH
LIKE FWC INDICATES.
.
FWC/FAN TEMPS ARE NOW RUNNING PRETTY CLOSE TO ACTUAL SO WILL MAKE
NO BOLD SUGGESTIONS ABOUT DEVIATING.
