NATIONAL WEATHER SERVICE PADUCAH KY
200 PM CDT SAT JUL 12 2003

IT APPEARS THE FRONT HAS SAGGED FAR ENOUGH SOUTH TO KEEP PCPN
CHANCES SOUTH OF FA AND ALLOW DRIER AIR TO WORK INTO ALL BUT VERY
SRN MOST PTNS FA AS OF 18Z. WL THEREFORE TENTATIVELY PLAN ON NO POPS
THIS EVENING...BUT WL MAINTAIN CLOSE WATCH ON 88D FOR PM DEVELOPMENT
NR THE BOUNDARY AND WL INCLUDE AN EVENING MENTION IF SOMETHING POPS
UP.

OTHERWISE LTL CHANGE IN GOING PACKAGE AS MODEL DATA...WHAT IS
AVAILABLE...REMAINS CONSISTENT WITH ITS MAINLY DRY FORECAST UNTIL
MID WEEK. 00Z MRF AND MEX STILL NOT AVAILABLE SO PLAN LTL/NO CHANGE
IN THE MID-LONG RANGE...BUT WL WATCH FOR IT UP THRU PRESS TIME. EVEN
WITH IT DONT ANTICIPATE MUCH CHANGE AS NEW 120 HR GFS OFFERS LTL
NEW FROM PREVIOUS RUNS/GOING PACKAGE. ONLY CONSIDERATION IS WHETHER
TO INCLUDE TUE NIGHT MENTION OF A POP PER NEWEST GFS...BUT GIVEN
TRENDS HAVE BEEN FOR SLOWER FRONTAL APPROACHES WITH TIME...THINK
WELL OPT TO LEAVE IT AT JUST A WED-THU CHC FOR NOW.

.PAH...NONE.
