AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
230 AM CDT TUE SEP 10 2002

COLD FRONT ON TRACK AS FORECAST TONIGHT...EXTENDING FROM HUTCHINSON 
MN...TO STORM LAKE IA TO LINCOLN NE AT 7Z. STRONGEST UPPER SUPPORT 
AND CONVECTION OVER MN...WITH PRECIP FALLING APART ALONG THE CENTRAL 
SECTION OF THE BOUNDARY OVER NWRN IA.  

IMMEDIATE CONCERN IS PRECIP POTENTIAL WITH FRONT TODAY THEN AMOUNT 
OF COOL DOWN WEDNESDAY.  

UPPER WAVE/JET STREAK LAGGING WELL BEHIND THE FRONT. SO FROPA THIS 
MORNING WILL BE DRY.  GREATEST HOPE OF RAIN WILL COME JUST BEHIND 
THE FRONT THIS AFTERNOON AS SOUTHERN TAIL OF UPPER WAVE SAGS INTO 
THE MID MISSISSIPPI VALLEY. UPPER SUPPORT WILL BE WEAKENING AS IT 
PUSHES SOUTH...BUT SHOULD STILL BE ENOUGH TO KICK OFF A FEW SHOWERS 
IN AREA OF POST-FRONTAL LIFT.  CLOUDS WILL INHIBIT TEMPS TODAY.  NO 
DRAMATIC COOL DOWN WITH THE INCOMING PACIFIC AIR MASS...BUT RATHER A 
REFRESHING RETURN TO NORMAL TEMPS FOR A FEW DAYS.  SOUTHERLY FLOW TO 
RETURN THURSDAY...BEGINNING A BRIEF WARMUP.

QUICK PEEK AT THE NEW MRF SHOWS MORE AMPLIFIED SYSTEM STILL ON THE 
BOOKS FOR THIS WEEKEND...SO NO CHANGES TO EXTENDED ATTM.

.DVN...
IA...NONE.
IL...NONE.
MO...NONE.
