230 PM CDT SAT AUG 24 2002

MODELS KEEP WEAK FLOW REGIME ACROSS THE REGION FOR SEVERAL DAYS WITH
HIGH PRESSURE RIDGES OFF TO THE WEST OR NORTH. LIGHT WINDS/WET GROUND
AND PLENTIFUL LOW LEVEL MOISTURE POINT TO FOG DEVELOPMENT
TONIGHT/SUNDAY MORNING. SATELLITE TRENDS INDICATE CLOUD COVER BECOMING
MORE CELLULAR WITH TIME SO CLOUDS SHOULD DISSIPATE AFTER SUNSET. ONE OF
THE LARGER NEGATIVES ON FOG DEVELOPMENT TONIGHT IS CLIMATOLOGICAL
UNFAVORABLE WINDS. HOWEVER THE PROS TOWARD FOG DEVELOPMENT SHOULD
OVERRULE THE NEGATIVE WINDS. THEREFORE WILL RAISE HEADLINES FOR THE
FOG ADVISORY TONIGHT. SINCE NOT MUCH CHANGES ON SUNDAY FOG
REDEVELOPMENT SUNDAY NIGHT IS DEFINITE...AND LIKELY DENSE AGAIN. MONDAY
NIGHT SHOULD SEE FOG AS WELL...BUT NOT LIKELY TO THE EXTENT OF
PREVIOUS TWO NIGHTS.

WEAK TROF MOVING THROUGH ON SUNDAY LIKELY NOT TO DO MUCH AS ATMOSPHERE
WILL STILL BE FAIRLY STABLE FROM OVERNIGHT FOG. MONDAY TO BE QUIET
WEATHER AGAIN.

FWC/MAV AGAIN QUITE CLOSE FOR ALL PERIODS. THUS WILL MAKE ADJUSTMENTS
AS NEEDED.

EXTENDED PRETTY QUIET WITH THE EXCEPTION OF WEDNESDAY NIGHT/THURSDAY.
SYSTEM PROGGED TO COME THROUGH LATE WEDNESDAY NIGHT OR THURSDAY WITH
SOME MOISTURE. FORCING NOT OVERLY GREAT BUT CHANCE POPS STILL LOOK
GOOD. REMAINDER OF THE WEEK TO BE DRY.

COORDINATED WITH DSM..LSE...CHI...ILX...AND STL.
