AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
150 PM CDT SAT AUG 26 2000

MAIN CONCERN THIS FCST PERIOD WILL BE PCPN CHCS INTO TNGT AND
POSSIBILITY OF SVR WX.

TWO MORNING TSRA COMPLEXES COMPLICATING MATTERS FOR THIS AFTERNOON
AND EVENING. WIDESPREAD WAA PCPN DEVELOPED ACROSS CENT IL EARLY THIS
MORNING AND STILL PERSISTING INTO E CENT IL ATTM. ANOTHER MCS MOVED OUT
OF NE IA INTO NRN IL AND HAS PLACED AN OUTFLOW BOUNDARY AS FAR SOUTH
AS A BRL TO BMI LINE AT 18Z AS VISIBLE ON SAT PIX. THIS OUTFLOW
BOUNDARY SHOULD BE PRIMARY CONCERN AS WE PROGRESS THROUGH THE
AFTERNOON.

WAA PCPN STILL GOING IN SE LIMITING INSOLATION THIS AFTERNOON.
ALTHOUGH...SOME CLEARING IS NOSING IN BEHIND WAA CONVECTION INTO
CENT IL ATTM. IN RESPONSE...LI'S RUNNING MINUS 6 TO 8 FROM NRN MO
INTO W CENT IL...AHEAD OF OUTFLOW BOUNDARY. AS CLOUDS CONT TO THIN
ACROSS CENT IL...INSTABILITY SHOULD CONT TO INCREASE AS THERE IS
STILL PLENTY OF TIME FOR HEATING ESPECIALLY W CENT AREAS.  WITH
PLENTY OF LOW LEVEL MOISTURE IN PLACE AND MID LEVEL S/W TROF ALSO
MOVING INTO AREA...ADDITIONAL TSRA DEVELOPEMENT STILL LOOKS
LIKELY... ESPECIALLY ALONG AND SOUTH OF OUTFLOW BOUNDARY. THIS WILL
NEED TO BE MONITORED UP TO PRESS TIME.

BEYOND THE FIRST PERIOD...UPPER LEVEL RIDGING BUILDS IN BEHIND
AFORMENTIONED S/W AND S/W'S PROGRESSING ACROSS SRN CANADA BEGIN TO
FLATTEN RIDGE AND FLOW BECOMES MORE ZONAL ACROSS THE NRN US BY TUES.
CURRENT FRNT INTO IA WILL SHIFT S OF ILX CWA BY 12Z SUN. THIS SHOULD
DRY MOST OF AREA OUT FOR SUN AS IT STALLS AGAIN ACROSS CENT MO INTO
SRN IL. NEXT SYSTEM PULLS INTO PLAINS BY MONDAY MORN. STRONG WAA AS
30-40KT LLJ FEEDS INTO ERN IA BY 12Z OVER TOP OF LINGERING FRNT INTO
MO. SHOULD MCS DEVELOP INTO ERN IA...IT SHOULD DROP SE AND DIE INTO
CENT IL MON MORN. WILL CONSIDER ADDITION OF SMALL POPS MON MORN FOR
ESPECIALLY THE NORTH.

BEYOND THIS PERIOD...AREA SHOULD BE INFUENCED BY NRN EDGE OF UPPER
LVL RIDGING.

PRELIMINARY CCF FOR COORDINATION PURPOSES ONLY...
