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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1208 PM CDT FRI JUN 13 2008

.DISCUSSION...
ISSUED 1159 AM CDT FRI JUN 13 2008

UPDATED FORECAST FOR SEVERE THUNDERSTORM WATCH ISSUED FOR EASTERN
IL FROM I-57 EAST THROUGH 8 PM. BROKEN LINE OF STRONG TO SEVERE
THUNDERSTORMS FROM DANVILLE TO EFFINGHAM AND MOVING ENE BETWEEN
20 AND 30 MPH. CONTINUED FLASH FLOOD WATCH ACROSS CENTRAL AND SE
IL THROUGH 7 PM. MAIN THREAT OF HEAVY RAIN APPEARED TO HAVE SHIFTED
SE OF THE IL RIVER SO MAY REMOVE SOME NW COUNTIES FROM THE FLASH
FLOOD WATCH.

17Z/NOON SURFACE MAP SHOWS A COLD FRONT EXTENDING FROM CENTRAL WI
TO ALONG THE IA/IL BORDER INTO NW MO AND SE KS. BANDS OF
CONVECTION AHEAD OF THIS COLD FRONT OVER IL WITH BROKEN STRONG TO
SEVERE LINE OF STORMS FROM DANVILLE TO EFFINGHAM AND INTO SW IL
NEAR THE MS RIVER. TROPICAL AIR MASS OVER IL AHEAD OF FRONT WITH
DEWPOINTS RANGING FROM THE MID 60S FROM I-57 WEST TO THE LOWER 70S
SE OF I-70 AND NEAR THE IL/IN BORDER AHEAD OF LINE OF STORMS. TEMPS
IN THE 80S AHEAD OF THE LINE OF STORMS AND RAIN COOLED UPPER 60S
AND LOWER 70S WEST OF I-57. ALOFT A STRONG 591 DM 500 MB RIDGE WAS
OVER THE ATLANTIC AND GULF COAST STATES INTO NORTHERN MEXICO WHILE
AN UNSEASONABLY STRONG 543 DM 500 MB LOW WAS NEAR THE SOUTHERN
MANITOBA AND ONTARIO BORDER.

HIGH CHANCES OF CONVECTION THIS AFTERNOON WITH SEVERE WX AND FLASH
FLOOD THREAT CONTINUING ESPECIALLY EAST OF I-57 ESPECIALLY INTO MID
AFTERNOON AS FRONT MOVES INTO IL. MODELS SHOW CONVECTION
DIMINISHING OVER EASTERN IL DURING THIS EVENING AS WEAKENING COLD
FRONT MOVES INTO INDIANA. CONVECTION LINGERS LONGEST SE OF I-70
TONIGHT. AROUND 1 INCH OF RAIN LIKELY IN EASTERN IL WITH LOCAL 2
INCH AMOUNTS POSSIBLE. FLOOD WARNINGS CONTINUE FOR
RICHLAND...LAWRENCE...JASPER... CRAWFORD AND CLARK COUNTIES.
COOLED HIGHS A FEW DEGREES FROM I-55 WEST WITH UPPER 70S AND MID
TO UPPER 80S NEAR THE INDIANA BORDER BEFORE STORMS COOL THEM OFF.

.AVIATION...
ISSUED 552 AM CDT FRI JUN 13 2008

CONVECTION CONTINUES TO MOVE IN FROM MO BUT THE INTENSITY HAS
WEAKENED CONSIDERABLY OVER THE PAST SVL HOURS. THE OUTFLOW
BOUNDARY WHICH PUSHED WELL AHEAD OF THE STORMS HAS CLEARED ALL THE
TAF SITES. THIS FEATURE MAY PROVIDE THE MAIN FOCUS FOR ADDL STORMS
THIS AFTN...AND THAT WOULD BE JUST SOUTH OF OUR TAF SITES.
HOWEVER... WITH THE COLD FRONT STILL OVER CNTRL IOWA...WL CONTINUE
TO CARRY AT LEAST A FEW HOURS OF TSRA THIS AFTN JUST AHEAD OF THE
BNDRY. WL START OUT WITH MOSTLY VFR CONDITIONS BUT WITH TEMPS
WARMING INTO THE UPPER 70S TO MIDDLE 80S BY LATE MRNG...A FAIRLY
DECENT CU FIELD SHOULD DEVELOP AS FORECAST SOUNDINGS INDICATE QUITE
A BIT OF LOW LVL MOISTURE AROUND TODAY. BEST THREAT FOR ORGANIZED
CONVECTION SHOULD BE IN THE 19Z TO 23Z TIME WITH THE STORM THREAT
SHIFTING TO THE SOUTH AND EAST THIS EVENING. WITH SLIGHTLY DRIER
AIR MOVING IN JUST BEHIND THE FRONT...WL CARRY SCT-BKN CIGS ARND
5000 FEET EARLY THIS EVENING WITH MAINLY SCT CONDITIONS AFTR 03Z.
SFC WNDS SHOULD BE OUT OF THE SW TODAY AND BECOME WEST AFTR FROPA
THIS EVENING.

.PREV DISCUSSION...
ISSUED 303 AM CDT FRI JUN 13 2008
UPPER LEVEL LOW STACKED OVER SFC LOW ON THE DAKOTA/CANADA BORDER
THIS MORNING. SFC FRONT STRETCHED OUT OVER THE UPPER
MIDWEST...DRAPED ACROSS IA MO...BACK INTO THE SRN PLAINS.
CONVECTION THAT FIRED ALONG FRONT LATER YESTERDAY AFTERNOON
FINALLY STARTING TO DIE DOWN ON THE ERN SIDE OF THE MISS RIVER
VALLEY. SOME REMAINING INSTABILITY IS MAINTAINING THE SOUTHERN
MOST PORTION OF THE STORMS IN SRN MO AND ERN KS. CONVECTION HAS
RUN AWAY FROM THE MAIN FRONT...LOSING ITS PUSH AS IT GETS FURTHER
AWAY FROM THE MAIN LIFT FOR THE SYSTEM. MAIN CONCERN FOR THE
FORECAST IS THE PRECIP THROUGHOUT TODAY...THE HOLES DEVELOPING IN
THE LINE...AND JUST HOW FAR THE FRONT WILL GET INTO THE CWA THIS
AFTERNOON TO COLLIDE WITH INCREASING INSTABILITY IN THE SERN
COUNTIES. THE NAM/WRF HAS HAD A PRETTY GOOD SOLUTION FOR THIS
PARTICULAR SYSTEM SINCE LAST NIGHT. WILL KEEP FOLLOWING IT FOR A
BIT. AS FOR THE MED RANGE...BOTH THE GFS AND THE ECMWF ARE IN
AGREEMENT FOR THE MON SYSTEM.

SHORT TERM...TODAY AND TOMORROW...
NAM/WRF HAS THE WEAKENING TREND IN THE PRECIP THAT IS CURRENTLY
REFLECTED IN THE RADAR MOSAIC PUSHING INTO THE IL RIVER VALLEY.
MID LEVEL JET MAINTAINING THE CLUSTER MOVING OFF TO THE NORTH AND
NORTHEAST...AND PLENTY OF INSTABILITY TO FEED THE STORMS MOVING
INTO THE SOUTHERN PLAINS. FRONT IS DRIFTING SLOWLY...ALMOST
STATIONARY AS IT GETS CAUGHT UP IN SWRLY FLOW. ANOTHER WAVE IS
PUSHING IN BEHIND IT ON SATELLITE REPRESENTATION...CLEARING THE
CLOUDS AND PROVIDING ANOTHER PUSH THAT SHOULD MOVE THE FRONT
THROUGH THE REGION TODAY AND THIS AFTERNOON. COLLISION OF THE
FRONT AND INCREASING INSTABILITY IN THE SOUTH AND EAST OF THE CWA
WILL PROVIDE THE NEXT ROUND OF SEVERE WEATHER. TO DATE...THIS
SYSTEM HAS BEEN A MOSH OF WINDS HAIL AND ISOLATED TORNADOS...AND
SEE NO REASON TO DISCONTINUE THAT THINKING. BIGGEST THREAT WILL BE
A COMBINATION OF VERY THICK LAYER THAT IS ALMOST SATURATED...AND A
FRONT THAT IS SLOWLY MOVING. WITH THE FRONTS FORWARD SPEED A BIT
OF A QUESTION MARK...HAVE NO PROBLEM WITH KEEPING THE FFA
GOING...ESPECIALLY WITH MANY AREAS STILL SATURATED AND DEALING
WITH FLOODING ALREADY. IN SUMMARY...MODELS GIVE US A LITTLE BIT OF
A BREAK THROUGH THE MORNING. FIRING OFF MORE CONVECTION AND HEAVY
RAINS IN THE EARLY AFTERNOON. FRONT SHOULD MAKE IT THROUGH THE
REGION IN THE OVERNIGHT HOURS...LEAVING SATURDAY AFTER 12Z DRY FOR
THE FA.

LONG TERM...SUNDAY THROUGH TUESDAY...
AN OVERALL SWITCH TO MORE NWRLY FLOW ALOFT BEHIND THIS
SYSTEM...DROPPING ANOTHER WAVE INTO THE REGION LATE SUNDAY INTO
THE NW. CHANCE POPS BEST FOR THE ENTIRE CWA SUNDAY
NIGHT...LINGERING INTO MON MORNING. CONFIDENCE IN THIS SYSTEM IS
LOW ENOUGH THAT NOT GOING TO GO HIGHER THAN CHANCE. TIMING ON THIS
ONE IS TOO LIKELY TO SHIFT SOMEWHAT. MILDER TEMPS AND DRY INTO THE
MIDWEEK.
