The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 21, 2:37 PM CDT, 2 hours 55 minutes earlier.

Area forecast discussion, Jun 21, 2:37 PM CDT, 2 hours 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
237 PM CDT SAT JUN 21 2008

.DISCUSSION...
ISSUED 237 PM CDT SAT JUN 21 2008

SHORT TERM MODELS LOOKS PRETTY SIMILAR WITH OVERALL UPPER LEVEL
PATTERN AND SURFACE PATTERN NEXT SEVERAL DAYS. IN THE LONG
TERM...A BLEND OF THE ENSEMBLES APPEARS THE WAY TO GO AND WILL BE
CONSISTENT WITH PREVIOUS FORECAST.

MAIN CONCERNS THIS PACKAGE WILL BE CHANCES OF PCPN THIS
EVENING...TOMORROW AND THEN AGAIN FROM THE MIDDLE OF NEXT WEEK
THROUGH THE END OF THE WEEK.

SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT

CONVECTION HAS FINALLY FIRED AGAIN ALONG THE FRONT/SHORT
WAVE/BOUNDARY THAT HAS BEEN MOVING THROUGH THE AREA TODAY AND INTO
THIS AFTERNOON. THIS CONVECTION WILL LIKELY CONTINUE INTO THE
EARLY EVENING HOURS...BUT MAINLY IN THE SOUTHEAST. SO WILL KEEP
SCT CONVECTION FOR A FEW HOURS ALONG AND SOUTH OF I-70. THEN THE
NEXT CHC OF PCPN WILL BE TOMORROW AS A STRONGER SYSTEM MOVES INTO
THE AREA. EVEN THOUGH THE LOW LEVEL MOISTURE WILL BE LIMITED...THIS
SYSTEM WILL HAVE STEEPER LAPSE RATES THAN TODAY AS COOLER AIR
ADVECTS INTO THE REGION IN THE UPPER LEVELS. BASED ON THIS...SPC
HAS INCLUDED US IN A SLIGHT RISK FOR SVR WEATHER AGAIN
TOMORROW...AND AGREE WITH THIS ASSESSMENT. THIS WILL THEN PUSH
THROUGH THE AREA BY LATE AFTERNOON BUT COULD HAVE SOME LINGERING
PCPN IN THE EAST AND SOUTHEAST DURING THE EVENING. SO HAVE
INCLUDED A SCHC FOR THE EVENING HOURS. THEN HIGH PRSS WILL BUILD
INTO THE REGION FOR MONDAY INTO TUESDAY. THIS WILL PROVIDE A BRIEF
DRY PERIOD AS THE PATTERN CHANGES FOR THE REMAINDER OF THE WEEK.

AS THIS PATTERN CHANGES AND THE SFC HIGH PRSS MOVES OFF TO THE
EAST...SOUTHERLY WINDS WILL RETURN AND BRING WAA AND MOISTURE
ADVECTION BACK INTO THE AREA. A WEAK WARM FRONT WILL THEN MOVE UP
INTO THE AREA AND BRING THE RETURN OF PCPN TO CENTRAL IL FOR
TUESDAY NIGHT.

TEMPS WILL COOL SLIGHTLY AFTER THIS THE NEXT TWO WAVES MOVE
THROUGH THE AREA AND THE LONG WAVE TROUGH SITS OVER CENTRAL IL THE
NEXT COUPLE OF DAYS. MODEL GUIDANCE APPEARS TO HANDLE THIS OK AND
HAVE COOLED TEMPS RESPECTIVELY.

LONG TERM...WEDNESDAY THROUGH SATURDAY

FAST QUASI-ZONAL FLOW WILL CONTINUE THROUGH THE REST OF NEXT
WEEK. THIS PATTERN WILL BE VERY FAVORABLE FOR WEAK SHORT WAVES TO
QUICKLY MOVE THROUGH THE FLOW AND BRING REOCCURRING CHANCES OF
STORMS TO THE AREA. WILL LIKELY BE SOME DRY PERIODS BUT TIMING IS
QUITE DIFFICULT THIS FAR OUT. THEREFORE WILL HAVE TO HAVE SOME
LEVEL OF CHC POPS IN THE FCST EACH DAY. FINE TUNING OF THE FCST
FOR DRY PERIODS CAN BE DONE WHEN DETAILS CAN BE BETTER SEEN. SO A
30-40PCT POP WILL BE IN EACH PERIOD FOR NOW.

SOUTHERLY WINDS THROUGH THE PERIOD WILL BRING LOTS OF WAA TO THE
AREA. WARM TEMPS ABOVE NORMAL SHOULD BE COMMON FROM WED TO SAT.
MEX GUIDANCE LOOKS CLOSE SO HAVE KEPT TEMPS CLOSE TO GOING FCST.

AUTEN

.AVIATION...
ISSUED 653 AM CDT SAT JUN 21 2008

THUNDERSTORMS FIRING EARLY THIS MORNING AHEAD OF A WEAK FRONTAL
BOUNDARY SINKING SOUTH FROM THE UPPER MIDWEST/GREAT LAKES. THE
BOUNDARY WILL CONTINUE TO BE THE FOCUS FOR CONVECTIVE DEVELOPMENT
TODAY...BUT IT SHOULD BE SOUTH OF THE TERMINALS BY LATE AFTERNOON.
SOUTHWEST WINDS ARE EXPECTED UNTIL THE BOUNDARY PASSES... WITH
NORTHWEST WINDS BEHIND IT. VFR CONDITIONS WILL PREVAIL...BUT MAY
BRIEFLY DROP INTO THE MVFR CATEGORY WITH THUNDERSTORMS.
