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 00:00Z, 1.9 hours before the alert went out and 129 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, Jul 21, 7:50 PM EDT, 2 hours 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
750 PM EDT FRI JUL 21 2006

.AVIATION...

DISCUSSION FOR 00Z TAF ISSUANCE.

DERECHO CLUSTER THAT MOVED ACROSS SOUTHERN ILLINOIS AND INDIANA HAS
PUSHED INTO EAST KENTUCKY AND TENNESSEE. MORE STABLE BUT HUMID
NORTHERLY FLOW ACROSS MOST OF INDIANA AND ILLINOIS.  UPPER SHORT
WAVE TROUGH STILL TO OUR WEST MAINTAINING A BROAD AREA OF SHOWERS
AND ISOLATED THUNDERSTORMS ACROSS NORTH HALF OF ILLINOIS WITH NEW
DEVELOPMENT TRAILING SOUTHWEST INTO MISSOURI.

IFR CONDITIONS AT 00Z AT BMG SHOULD IMPROVE SHORTLY AS NORTH BREEZES
BEGIN TO PICK UP AND DRY OUT RECENT RAIN. VFR CONDITIONS REMAINING
TAF SITES. ILLINOIS PCPN TO ARRIVE BETWEEN 01Z AND 03Z AND LAST
SEVERAL HOURS BUT REMAIN AS VFR. AFTER 08Z EXPECT MVFR DECKS AND
VSBYS TO DEVELOP WITH CONTINUED LATE NIGHT COOLING. UPPER TROUGH
FINALLY PUSHES FAR ENOUGH EAST AFT 13Z SATURDAY TO SCOUR OUT LOW
DECKS AND FOG. MID DECKS BY LATE MORNING TO BE REPLACED BY SCT CU
FOR AFTN HOURS SAT.

&&

.PREVIOUS DISCUSSION...MAY PROBLEM WILL BE THE TIMING OF THE
THUNDERSTORMS. A COLD FRONT WAS IN SOUTHERN INDIANA. A SHORT WAVE
WAS MOVING ALONG THE FRONT. LIFTED INDEXES DROP TO BETTER THEN -6 IN
SOUTHERN INDIANA. THE MAIN AREA OF UNSTABLE AIR WILL MOVE SOUTH OF
CENTRAL INDIANA CWA. A FEW OF THE SEVERE STORMS MAY CLIP EXTREME
SOUTHWEST COUNTIES UNTIL EARLY EVENING. THESE MAY PRODUCE WIND GUSTS
IN EXCESS OF 60 MPH ALONG WITH VERY HEAVY RAIN.

SHOWERS OVER CENTRAL AND NORTHERN INDIANA ARE ASSOCIATED WITH A 500
MB SHORT WAVE. THIS WILL MOVE THROUGH INDIANA OVERNIGHT. DUE TO ALL
THIS INSTABILITY HAVE RAISED POPS TO AT LEAST LIKELY.

THE FRONT WILL MOVE SOUTH OF INDIANA ON SATURDAY. THE ATMOSPHERE
WILL QUICKLY STABALIZE AS THE FRONT MOVES EAST. JUST WENT FOR A
CHANCE OF SHOWERS EAST AND SOUTHEAST SATURDAY MORNING. DRIER AIR
MOVES IN DURING THE AFTERNOON SO DECREASED CLOUD COVER SOME THEN.

WITH THE DRIER AIR CONTINUING TO MOVE IN CONTINUED TO DECREASE CLOUD
COVER SATURDAY NIGHT. PARTLY CLOUDY ON SUNDAY. GOING FORECAST TEMPS
LOOK OK.
