What forecasters said that day

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 10, 3:08 PM CDT, 3 hours 12 minutes earlier.

Area forecast discussion, Jun 10, 3:08 PM CDT, 3 hours 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
308 PM CDT FRI JUN 10 2011

.DISCUSSION...
ISSUED 308 PM CDT FRI JUN 10 2011

MODELS FAIRLY CONSISTENT AND LOOK SIMILAR IN THE OVERALL UPPER
LEVEL PATTERN AND GENERAL SURFACE FEATURES. MODELS DIFFER AND HAVE
TROUBLES HANDLING THE DETAILS OF WHEN AND WHERE THE PCPN WILL
OCCUR...ESPECIALLY IN THE SHORT TERM OF TONIGHT. LONGER TERM
MODELS CONTINUE TO SHOW AN UNSETTLED PATTERN THROUGH NEXT WEEK
BRINGING CHANCES OF STORMS MOST OF THE TIME.

MAIN CONCERNS ARE CHANCES OF PCPN TONIGHT AND THEN AGAIN NEXT
WEEK.

SHORT TERM...TONIGHT THROUGH MONDAY NIGHT

BOUNDARY HAS BECOME ACTIVE IN SOUTHEAST ILLINOIS WHERE BEST
CONVERGENCE AND CAPE IS LOCATED AT. NORTHERN AREAS OF CWA ARE
CAPPED BUT LARGE AREA OF PCPN SHOWERS AND THUNDERSTORMS ACROSS
SOUTHERN IOWA AND PARTS OF NORTHERN MISSOURI WILL CONTINUE TO MOVE
ENE INTO THE NORTHERN THIRD OF ILLINOIS THIS EVENING. AS THIS
SYSTEM CONTINUES TO MOVE EAST...SHOWERS AND THUNDERSTORMS ARE
LIKELY ACROSS MOST OF THE AREA TONIGHT AND INTO THE OVERNIGHT
HOURS. THE STORMS IN THE SOUTHEAST WILL CONTINUE AS WELL WITH
LOCALLY HEAVY RAINFALL POSSIBLE DUE TO THE SLOW MOVEMENT.

THEN BRIEF HIGH PRSS WILL BUILD INTO THE AREA SATURDAY NIGHT AND
SUNDAY BEFORE THE CHANCES OF PCPN RETURNS FOR SUNDAY NIGHT THROUGH
MONDAY NIGHT. THE FRONT THAT PUSHES THROUGH THE AREA THIS
AFTERNOON WILL MOVE SOUTH OF THE CWA BUT THEN MOVE BACK NORTH INTO
MISSOURI AT THE END OF THE WEEKEND. THIS WILL BE THE FOCUS OF MORE
SHOWERS AND STORMS FOR THE END OF THE WEEKEND AND INTO NEXT WEEK.
THE CHANCES OF STORMS WILL BE CONFINED TO THE WESTERN PARTS OF THE
CWA AS NOCTURNAL CONVECTION WILL BE THE LIKELY MODE THROUGH THE
PERIOD.

TEMPS SHOULD BE ON THE COOLER SIDE...BELOW NORMAL...DUE TO PCPN
AND CLOUD COVER.

LONG TERM...TUESDAY THROUGH FRIDAY

THE FRONT WILL REMAIN JUST TO THE WEST OF THE CWA AT THE BEGINNING
OF THE PERIOD...BUT SLOWLY INCH EASTWARD DURING THE PERIOD. THIS
WILL INCREASE CHANCES OF PCPN EASTWARD. THERE WILL BE PERIODS OF
DRY WEATHER BUT WITH RIDGE TO THE EAST AND CONTINUED SOUTHWEST
FLOW ALOFT...AND FRONTAL SYSTEM TO THE WEST OR OVER THE CWA...PCPN
WILL CONTINUE. FINALLY A LOW PRSS AREA DEVELOPS PUSHES THE FRONT
NORTH THROUGH THE AREA AS A WARM FRONT...FOLLOWED BY A COLD FRONT
WED AND WED NIGHT. CHANCES OF PCPN WILL CONTINUE WITH THIS SYSTEM
PASSAGE. ANOTHER HI PRSS AREA WILL MOVE IN LATER IN THE WEEK AND
BRING DRY WEATHER FOR THUR THROUGH FRIDAY.

TEMPS WILL RETURN TO NORMAL THROUGH THE PERIOD.

.AVIATION...
ISSUED 1234 PM CDT FRI JUN 10 2011

MID-LEVEL CLOUD DECK WILL PERSIST ACROSS CENTRAL ILLINOIS INTO
THE EARLY AFTERNOON. CURRENT SATELLITE IMAGERY SHOWS CU FIELD
DEVELOPING SOUTH OF THE TERMINALS FROM NEAR PARIS W/SW TO SAINT
LOUIS. AS THE DAY PROGRESSES...CU WILL DEVELOP FURTHER NORTH AS
THE ATMOSPHERE STEADILY DESTABILIZES. DIFFICULT TO PINPOINT EXACT
TIMING/LOCATION OF CONVECTION LATER TODAY...AS STORMS WILL FIRE
ALONG MESOSCALE BOUNDARIES. MOST FAVORABLE TIME FOR STORMS WILL BE
AFTER 21Z. HAVE INCLUDED A VCTS GROUP AT THE TAF SITES AFTER THAT
TIME...AND WILL WAIT UNTIL CONVECTIVE TRENDS BECOME CLEARER BEFORE
ATTEMPTING TO FURTHER CLARIFY TIMING AT INDIVIDUAL TERMINALS. MAIN
PUSH OF STORMS WILL BE LATE THIS AFTERNOON AND EVENING...WITH
PRECIP SHIFTING E/SE OF THE AREA OVERNIGHT. AS WINDS SWITCH TO NW
AFTER MIDNIGHT...LOWER CEILINGS OF AROUND 1500FT CURRENTLY OVER
IOWA WILL SPILL SOUTHEASTWARD INTO CENTRAL ILLINOIS. LOW CLOUDS
WILL THEN PERSIST THROUGH 18Z...BEFORE SKIES CLEAR FROM WEST TO
EAST SATURDAY AFTERNOON.
