AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
910 PM CDT TUE AUG 26 2003

ISOLATED/SCT CONVECTION STILL ONGOING OVER WESTERN AND EASTERN
PORTIONS OF THE CWA. SVR THREAT LOOKS KIND OF MARGINAL WITH SO MUCH
WARM AIR ALOFT BUT WITH SFC TEMPS STILL IN THE LOW-MID 80S AND WEAK
SFC BOUNDARIES IN THE AREA...WOULDNT WANT TO RULE ANYTHING OUT JUST
YET. COORDINATED A FEW TIMES THIS EVENING WITH SPC AND THEY ARE
PRETTY MUCH IN THE SAME BOAT.

SFC PATTERN RATHER COMPLICATED WITH WEAK TROFFS OUT AHEAD OF THE
MAIN COLD FRONT WHICH APPEARS TO STILL BE LOCATED NEAR THE IL/WI
BORDER AND TRAILING BACK TO THE SW. 18Z M-ETA SHOWING GOOD LIFT LATE
TONIGHT AS WEAK BNDRYS SLOWLY DRIFT SWRD. MAIN FROPA NOT EXPECTED
UNTIL AFTER 12Z SO MOST LOCATIONS WILL LIKELY STAY QUITE WARM
OVERNIGHT WITH PC TO OCCASIONALLY MC SKIES ACROSS THE CENTRAL ZONES.

ALL SAID AND DONE...WILL UPDATE ZONES TO TWEAK POPS/TEMPS HERE AND
THERE. WILL RAISE POPS IN THE CENTRAL ZONES TO 40 OR 50
PERCENT...MAY LOWER THE POPS IN THE NORTH DOWN TO 40%. THE FAR SE
ZONES MAY STAY DRY OVERNIGHT BUT WILL PROBABLY LEAVE A SMALL POP
THERE TO BE SAFE.

WILL MONITOR TRENDS A FEW MORE MINUTES BEFORE ISSUING ZONE UPDATE.

.ILX...NONE.
