Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

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 Oct 18, 2:53 AM CDT, 2 hours 35 minutes earlier.

Area forecast discussion, Oct 18, 2:53 AM CDT, 2 hours 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
253 AM CDT THU OCT 18 2007

.DISCUSSION...
ISSUED 253 AM CDT THU OCT 18 2007

MAIN STORY WILL BE THE POTENTIALLY VOLATILE WEATHER TODAY...WITH
EASTERN HALF OF THE KILX CWA IN A MODERATE RISK FOR SEVERE STORMS.

LATEST SURFACE CHART SHOWS 987MB LOW OVER EASTERN NEBRASKA...WITH
COLD FRONT EXTENDING SOUTHWESTWARD INTO THE TEXAS PANHANDLE.
ALOFT...UPPER LOW IS CENTERED OVER THE CENTRAL PLAINS...WITH
NUMEROUS SHORT-WAVES ROTATING AROUND THE PARENT LOW ACROSS THE
SOUTHERN PLAINS INTO THE MISSISSIPPI RIVER VALLEY. SEVERAL LINES OF
CONVECTION HAVE DEVELOPED IN RESPONSE TO THE STRONG DYNAMICS
ACROSS THE REGION...WITH MAIN LINE NOW EXTENDING ACROSS WEST-CENTRAL
ILLINOIS.

SHORT TERM...TODAY THROUGH SATURDAY

FAST-MOVING LINE OF STORMS WILL CLEAR MUCH OF THE KILX CWA BY
12Z...WITH PERHAPS A FEW LINGERING SHOWERS/STORMS ALONG THE FAR
N/E BORDERS. ANY LINGERING PRECIP WILL QUICKLY SHIFT OUT OF THE
AREA SHORTLY AFTER SUNRISE...AS STRONG DRY SLOT BEGINS TO PUSH
NORTHEAST ACROSS MISSOURI TOWARD CENTRAL ILLINOIS. THE DAY WILL
START OFF CLOUDY...BUT SKIES SHOULD BECOME PARTLY TO MOSTLY SUNNY
BY MID-MORNING. WITH AMPLE SUNSHINE AND STRONG WAA...TEMPERATURES
WILL SOAR WELL INTO THE 70S...WITH MANY AREAS TOPPING THE 80
DEGREE MARK. IN ADDITION...A TIGHTENING PRESSURE GRADIENT AND
EXCELLENT MIXING WILL HELP PRODUCE SUSTAINED WINDS IN THE 20 TO 25
MPH RANGE...WITH GUSTS UP TO 40 MPH. BASED ON CURRENT LOW-LEVEL
PROFILERS AND 00Z FORECAST SOUNDINGS...IT APPEARS WINDS WILL
REMAIN JUST SHY OF ADVISORY CRITERIA TODAY.

AS DRY LINE/COLD FRONT PROPAGATES EASTWARD THIS AFTERNOON...LINE
OF CONVECTION STILL EXPECTED TO DEVELOP ACROSS PART OF THE AREA.
00Z 18 OCT MODELS HAVE SHIFTED LOCATION OF THUNDERSTORM INITIATION
A LITTLE FURTHER EAST THAN PREVIOUSLY THOUGHT. IN FACT...GFS/NGM
SUGGEST STORMS MAY FIRE ALONG THE ILLINOIS/INDIANA BORDER AFTER
21Z. MEANWHILE...NAM-WRF DEVELOPS THE STORMS FURTHER WEST BETWEEN
THE I-55 AND I-57 CORRIDORS. DUE TO THE THE RECENT GOOD PERFORMANCE
OF THE NAM-WRF...WILL FOLLOW ITS SOLUTION MOST CLOSELY. WILL
THEREFORE CARRY LIKELY POPS ALONG AND EAST OF A BLOOMINGTON TO
DECATUR LINE FOR THE LATE AFTERNOON...WITH ONLY CHANCE POPS
FURTHER WEST. ANY STORMS THAT FORM WILL HAVE PLENTY OF WIND
ENERGY AND INSTABILITY TO WORK WITH...SO DAMAGING WINDS AND LARGE
HAIL WILL BE THE PRIMARY THREATS. IN ADDITION...AMOUNT OF LOW-
LEVEL ENVIRONMENTAL WIND SHEAR SUGGESTS THE POTENTIAL FOR A FEW
TORNADOES...ESPECIALLY EARLY ON BEFORE STORMS CAN FORM INTO A
LINEAR STRUCTURE. STORMS SHOULD LINGER EAST OF THE I-57 CORRIDOR
INTO THE EARLY EVENING HOURS...SO WILL CONTINUE LIKELY POPS ACROSS
THE FAR EAST AFTER 00Z. ONCE THE STORMS PUSH INTO INDIANA...PRECIP
WILL COME TO AN END ACROSS THE AREA...WITH PERHAPS A FEW WRAP
AROUND SHOWERS AFTER MIDNIGHT. WILL ONLY CARRY SLIGHT CHANCE POPS
TO COVER THIS...AS LOW-LEVELS DRY OUT AND BEST UPPER SUPPORT
REMAINS WELL TO THE NORTH. CLOUDY AND WINDY WEATHER IN STORE FOR
FRIDAY...AS STRONG CAA PATTERN SETS UP. WILL CONTINUE TO UNDERCUT
GUIDANCE FOR TEMPS...WITH HIGHS ONLY IN THE LOWER TO MIDDLE 60S
ACROSS MOST LOCATIONS.

UPPER SYSTEM PULLS AWAY ON SATURDAY...REPLACED BY BROAD RIDGING.
AMPLE SUNSHINE AND STRONG WAA WILL HELP BOOST HIGH TEMPS BACK
ABOVE NORMAL...WITH READINGS RISING WELL INTO THE 70S.

LONG TERM...SUNDAY THROUGH WEDNESDAY

NOT MUCH CHANGE IN THE EXTENDED...AS MODELS CONTINUE TO BRING YET
ANOTHER STORM SYSTEM ACROSS THE COUNTRY LATE IN THE WEEKEND INTO
EARLY NEXT WEEK. GFS CONTINUES TO BE THE MOST PROGRESSIVE MODEL
WITH THIS FEATURE...WHILE ECMWF/CANADIAN BECOME MORE AMPLIFIED AND
THUS SLOWER WITH THE APPROACHING WAVE. AT THIS POINT...WILL FOLLOW
THE SLOWER CONSENSUS...WHICH KEEPS PRECIP OUT OF THE AREA UNTIL
MONDAY.

BARNES
&&

.AVIATION...
ISSUED 614 PM CDT WED OCT 17 2007

A BRIEF PERIOD OF LOWER VSBYS IS OCCURRING BEHIND THE INITIAL
DEPARTING WAVE OF PRECIPITATION. HOWEVER...GRADIENT CONTINUES TO
INCREASE AND WILL LIKELY BRING VSBYS INTO THE 4-6 MILE RANGE AHEAD
OF NEXT RAIN COMPLEX. LARGE AREA OF RAIN WITH EMBEDDED THUNDERSTORMS
OVER SOUTHERN ILLINOIS IS MOVING NORTH AND SHOULD ENVELOPE THE
CENTRAL ILLINOIS TERMINALS FROM SOUTH TO NORTH THIS EVENING.

WILDCARD IS CONVECTIVE LINE OVER MISSOURI. NCEP 18Z MODELS ARE NOT
HANDLING THIS FEATURE WELL AND IT IS ALREADY SIGNIFICANTLY EAST OF
WHERE THE MODELS WOULD INDICATE PRECIPITATION. WILL HAVE TO
MONITOR THIS LINE CLOSELY TO SEE WHETHER IT CAN MAKE IT EAST INTO
WEST CENTRAL ILLINOIS AFTER MIDNIGHT.

ANOTHER CONCERN TONIGHT IS POTENTIAL FOR LLWS. 00Z RAOB FROM KILX
HAS COME IN WITH 700 MB WINDS OF 41 KTS. WILL NOT INCLUDE LLWS IN
TAFS AT THIS TIME BUT WE WILL HAVE TO MONITOR CLOSELY.

TOMORROW IS A BIT MORE UNCERTAIN. DYNAMICS IS IMPRESSIVE...BUT
MOISTURE IS MUCH MORE LIMITED AS DRY SLOT PUSHES INTO ILLINOIS.
AT THIS TIME WILL EXPECT A THIN LINE OF CONVECTION TO DEVELOP
SOMEWHERE IN THE WESTERN HALF OF ILLINOIS AND THEN RACE EASTWARD
DURING THE AFTERNOON.  HAVE TIMED TERMINAL FORECAST ACCORDINGLY.
