What was reported inside it

Time	Report	Where	Remark
Sep 2, 7:00 PM CDT	HEAVY RAIN 1.85	2 W Riverton, IL	RAIN FALL TOTAL IN PAST ONE HOUR.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Lincoln, IL (KILX), launched 12:00Z, 10.5 hours before the alert went out and 90 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Sep 2, 3:02 PM CDT, 2 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
302 PM CDT THU SEP 2 2010

.DISCUSSION...
ISSUED 302 PM CDT THU SEP 2 2010

MAIN CONCERNS THIS PACKAGE INCLUDE PCPN CHANCES THIS EVENING AND
OVERNIGHT...FOLLOWED BY TEMPS INTO THE WEEKEND. THEN NEXT CONCERN
IS CHANCES OF PCPN FOR NEXT WEEK AND TEMPS.

MODELS IN VERY GOOD AGREEMENT ON BRINGING FRONT THROUGH CWA
QUICKLY THIS EVENING...FOLLOWED BY HIGH PRSS BRINGING IN DRIER AND
COOLER WEATHER FOR FRIDAY AND THROUGH THE WEEKEND. SO OF BLEND OF
THE SHORT TERM MODELS LOOKS GOOD THIS PACKAGE. IN THE LONG
TERM...MODELS AGREE THAT A RETURN TO SOUTHWESTERLY FLOW IS IN
STORE FOR NEXT WEEK AS THE UPPER LEVEL RIDGE PUSHES OFF TO THE
EAST AND SOUTHEAST.

SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT

COLD FRONT IS STILL WEST OF THE CWA/STATE AND APPEARS TO STILL BE
IN EASTERN IOWA AT 19Z. MODELS CONTINUE TO BRING IT THROUGH THIS
EVENING...REACHING INTO INDIANA BY 06Z. AHEAD OF THIS FRONT...SFC
DEWPOINTS STILL ARE AROUND 70 TO LOWER 70S. SO SHOWERS AND
THUNDERSTORMS WILL STILL BE POSSIBLE ACROSS THE CWA. SO WILL KEEP
A LIKELY POP IN FORECAST FOR THIS EVENING AND THEN DIMINISH IT TO
CHC IN THE SOUTHEAST FOR OVERNIGHT AS THE FRONT PUSHES EAST. AFTER
THE FRONT MOVES THROUGH...COOL AND DRY HIGH PRSS WILL BUILD INTO
THE CWA FOR INTO THE WEEKEND. THROUGH THE PERIOD THE UPPER LEVEL
FLOW WILL BE NORTHWESTERLY WHICH WILL ALLOW A COOLER THAN NORMAL
AIRMASS TO ADVECT INTO THE AREA. WINDS SHOULD BE A TAD GUSTY
TOMORROW AS A SECONDARY TROUGH SLIDES THROUGH THE GRT LKS REGION
AND THE HI PRSS RIDGE SITS OVER THE PLAINS. GRADIENT WILL THEN
DIMINISH FOR SAT AND SUN AS THE RIDGE DOMINATES THE WEATHER IN
CENTRAL IL.

TEMPS WILL BE BELOW NORMAL FOR THE PERIOD AND GUIDANCE LOOKS
REASONABLE AT THIS TIME.

LONG TERM...MONDAY THROUGH THURSDAY

THE HI PRSS WILL MOVE EAST TOWARD THE END OF THE WEEKEND AS THE
LONG WAVE TROUGH PUSHES EAST AS WELL. THIS SHOULD HELP KEEP THE
NEXT TWO TROPICAL SYSTEMS TO THE EAST OF THE STATES AS WELL. THE
UPPER LEVEL FLOW WILL ALSO BECOME MORE SOUTHWESTERLY DURING THE
WEEK WHICH WILL ALLOW ANOTHER WEATHER SYSTEM TO DEVELOP IN THE
PLAINS...BRINGING CHANCES OF PCPN TO THE CWA FOR TUE NIGHT AND
WEDNESDAY. TUE NIGHT AND WED LOOKS LIKE A COLD FRONT SLOWLY
FALLING INTO THE CWA AS THE MAIN SYSTEM STAYS ACRS THE NORTHERN
US. THIS FRONT APPEARS TO WASH OUT OF THE STATE THEN AND THEN
BEGIN TO LIFT BACK NORTH AS A WARM FRONT ON THUR...BRINGING
ANOTHER CHANCE OF PCPN TO THE AREA.

SOUTHWESTERLY FLOW WILL BRING THE RETURN OF WARMER TEMPS TO THE
REGION NEXT WEEK AND MEX GUIDANCE APPEARS TO HAVE A GOOD HANDLE ON
THIS.
