What was reported inside it

Time	Report	Where	Remark
Jun 22, 1:07 PM CDT	HAIL 0.75	5 Sw Kouts, IN

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 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.

The nearest sounding before it

Lincoln, IL (KILX), launched 12:00Z, 5.9 hours before the alert went out and 181 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
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1247 PM CDT SUN JUN 22 2008

.DISCUSSION...
319 AM CDT

POTENTIALLY ACTIVE WEATHER DAY ONCE AGAIN ACROSS THE AREA AS MAIN
UPPER LEVEL LOW CONTINUES TO SPIN ACROSS THE NORTHERN LAKES WHILE
MAIN UPPER RIDGE AMPLIFIES ACROSS THE NORTHERN HIGH PLAINS. MAIN
SHORTWAVE OF INTEREST IN THE NEAR TERM IS HIGHLY EVIDENT ON WATER
VAPOR IMAGERY THIS MORNING AS IT CONTINUES TO DIVE INTO THE UPPER
MISS RVR VLY FROM THE NORTHERN PLAINS. ON THE SFC...07Z OBJECTIVE
ANALYSIS SHOWS WELL DEFINED WIND SHIFT LINE/TROUGH STRETCHED FROM
NORTH CENTRAL WI...SWWD THROUGH SE MN. THIS FEATURE COMBINED WITH
APPROACHING SHORTWAVE TROUGH WILL LEAD TO INITIAL ROUND OF
SHWRS/STORMS THIS MORNING...AS SFC TROUGH AXIS CONTINUES TO SLIDE
INTO AREA.

LATEST SPC DAY 1 OUTLOOK HAS TRIMMED BACK SLIGHT RISK TO SOUTHERN
CWA WHICH APPEARS RATHER ACCEPTABLE CONSIDERING BEST DYNAMICS FOR
ORGANIZED CONVECTION WILL GRADUALLY SINK SOUTH AS THE DAY CONTINUES
ON. SHORT TERM GUIDANCE IN FAIRLY GOOD AGREEMENT WITH MAIN VORTEX TO
THE NORTH GRADUALLY SINKING SOUTHWARD ACROSS NORTHERN LAKES AS THE
DAY PROGRESSES. WITH THAT IN MIND...SHEAR AND INSTABILITY WILL ALSO
GRADUALLY SHIFT SOUTHWARDS THROUGHOUT THE DAY...AS MAIN SFC TROUGH
NOTED ABOVE SKIRTS SOUTHWARD AND 40-50KT MID LEVEL JET ARRIVE FROM
THE WEST. HOWEVER ENTIRE AREA IS BY NO MEANS OUT OF THE WOODS FOR
T-STORM DEVELOPMENT THIS MORNING AS SHORTWAVE TROUGH AND SFC TROUGH
AXIS ARRIVE DURING THE MID MORNING HRS. FAIRLY UNIMPRESSIVE
RADIATIONAL INVERSION NOTED ON LATEST ACARS SOUNDING FROM ORD THIS
MORNING AND BASED ON THIS...EXPECT VERY LITTLE CIN TO PREVENT
CONVECTIVE UPDRAFT INITIATION. WITH SUCH LIMITED WIND SHEAR
AVAILABLE (0-6KM BULK SHEAR VALUES OF ROUGHLY 20KTS) AND FAVORABLE
WET BULB ZERO LEVELS (8-9KFT) FEEL PULSE STORMS WILL BE THE MAIN
CONCERN THIS MORNING WITH MARGINAL HAIL AND DAMAGING WIND POTENTIAL
BEING THE BIGGEST THREATS. WRF/GFS IN GOOD AGREEMENT IN SHOWING
STEEPENING LOW LEVEL LAPSE RATES THROUGH THE MORNING DUE TO SOLAR
INSULATION...WITH MID LEVEL LAPSE RATES ALSO EXPECTED TO INCREASE AS
COLDER AIR IN ASSOCIATION WITH MAIN VORTEX TO THE NORTH SINKS
SOUTHWARD. ONLY CAVEAT RIGHT NOW IS JUST HOW MUCH CLOUD COVER WILL
MOVE IN EARLY THIS MORNING WITH APPROACHING SHORTWAVE...POSSIBLY
LIMITING DEGREE OF HEATING/INSTABILITY THIS MORNING. FOR NOW...HAVE
BUMPED POPS UP TO LIKELY ACROSS MUCH OF CWA WITH PREMISE THAT
SHWRS/STORMS MAY ARRIVE IN TWO SEPARATE BATCHES TODAY...WITH THE
SECOND BATCH ARRIVING THIS AFTERNOON AS NEXT SHORTWAVE CURRENTLY
ANALYZED NEAR THE ARROWHEAD OF MN ARRIVES BY AFTERNOON. AM EXPECTING
SECOND ROUND TO BE LESS OF A MENACE AS COMPARED TO THE FIRST AS ATM
WILL LIKELY BE STABILIZED DUE TO EARLIER CONVECTION... HOWEVER
CANNOT RULE OUT SCT STORMS.

BIG CHANGE IN WEATHER PATTERN EXPECTED BY MONDAY AS UPPER LEVEL
RIDGE OFF TO THE WEST FINALLY BEGINS NOSING INTO AREA...EFFECTIVELY
SENDING PESKY UPPER LEVEL LOW OFF TO THE EAST. SFC HIGH PRESSURE
EXPECTED TO GRADUALLY BUILD ACROSS REGION ON MONDAY...WITH NORTHERLY
TO NORTHEASTERLY FLOW EXPECTED AREA WIDE. FLOW OFF THE LAKE WILL
LEAD TO NOTICEABLE COOLER TEMPS ALONG THE IMMEDIATE LAKE
SHORE...WHERE ONLY UPPER 60S WILL BE POSSIBLE NORTH OF DOWNTOWN.
HIGH PRESSURE SIDES OFF TO THE EAST BY TUESDAY...WITH SOUTHEASTERLY
FLOW KEEPING IMMEDIATE LAKESHORE LOCATIONS COOLER ONCE AGAIN. UPPER
LEVEL FLOW EXPECTED TO DEAMPLIFY ON TUESDAY WITH FLOW BECOMING MORE
PROGRESSIVE WITH TIME. SHORTWAVE THROUGH EXPECTED TO BEGIN EJECTING
OUT THE OF THE CENTRAL PLAINS LATE TUESDAY...WITH MCS DEVELOPMENT
LIKELY ACROSS THE EASTERN CENTRAL PLAINS/MID MISS RVR VLY TUE NIGHT.
MODELS SHOWING RATHER IMPRESSIVE MOISTURE RETURN INTO AREA...HOWEVER
AS IS USUALLY THE CASE WITH THESE SITUATIONS...AVAILABLE MOISTURE
MAY BE OVERDONE WITH RATHER NOTICEABLE RIDGE AXIS PRESENT ACROSS
NORTHERN HALF OF GULF OF MEXICO. REGARDLESS...THIS FEATURE IS BEEN
WELL ADVERTISED IN RECENT DAYS AND CONFIDENCE IS INCREASING.
SO...EXPECT INCREASED CLOUDINESS TUE NIGHT WITH SCT ELEVATED
SHWRS/STORMS POSSIBLE BY WEDNESDAY MORNING ACROSS THE AREA AS MAIN
WARM FRONT LIES TO THE WEST OF THE REGION. TEMPS EXPECTED TO BEGIN
REBOUNDING ON TUE WITH RETURN OF SOUTHERLY FLOW ON TUE...WITH TREND
CONTINUING THROUGH MIDDLE TO LATTER PORTIONS OF THE WEEK.

.AVIATION...
1241 PM CDT

1800 UTC TAFS...FAIRLY TURBULENT DAY COMING INTO THE REGION TODAY
AS THUNDERSTORMS DEVELOP ACROSS THE TAF REGION OVER THE NEXT HOUR
OR SO AND LINGER THROUGH EARLY THIS EVENING. THE ATMOSPHERE IS
CURRENTLY UNSTABLE ENOUGH THAT CLEAR SKIES HAVE RAPIDLY TURNED
INTO A WIDESPREAD CU FIELD WITH SOME TOWERING CU MIXED IN. CURRENT
THINKING IS THAT STORMS WILL MAINLY COME IN TWO WAVES...ONE
THROUGH MID-AFTERNOON AND ANOTHER TONIGHT AS AN UPPER LEVEL
DISTURBANCE DROPS DOWN FROM WISCONSIN. TRENDED A BIT MORE ON THE
PESSIMISTIC SIDE EVEN THOUGH FORECAST CONFIDENCE IN TIMING ISNT
THE BEST DUE TO HOW TURBULENT THE CURRENT AIRSPACE AND HOW FAST A
TCU COULD DEVELOP. WIND FIELD IS CURRENTLY A MESS WITH A LEFTOVER
OUTFLOW BOUNDARY ALONG THE LAKE MICHIGAN SHORELINE AND ANOTHER SFC
TROF EXTENDING FROM EASTERN WISCONSIN ON DOWN INTO NORTHERN
ILLINOIS. THESE FEATURES MAY BECOME THE FOCUS FOR FURTHER
STORM DEVELOPMENT THIS AFTERNOON. WINDS SHOULD EVENTUALLY BECOME
NORTHWEST THROUGHOUT THE REGION THIS AFTERNOON...GOING NORTH
TOMORROW MORNING.

EXPECT MAINLY VFR CONDITIONS THROUGHOUT THE PERIOD WITH SOME BRIEF
DROPS DOWN TO MVFR POSSIBLE WITHIN THUNDERSTORMS.

1246 PM CDT

OUTSIDE OF SCATTERED THUNDERSTORMS CROSSING THROUGH THE
