The radar

The Evansville,IN radar (KVWX), 66 km from the middle of the area, began a volume at 02:09 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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, 2.2 hours before the alert went out and 164 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 29, 8:44 PM CDT, 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
844 PM CDT FRI JUL 29 2011

.DISCUSSION...
ISSUED 836 PM CDT FRI JUL 29 2011

WEAK COOL FRONT HAS SHIFTED JUST SOUTH OF INTERSTATE 70 EARLY
THIS EVENING WITH MOST OF THE CONVECTION OCCURRING ALONG THE
FRONTAL BOUNDARY. EXPECT THE MAIN THREAT FOR ADDITIONAL RAINFALL
TONIGHT WILL BE ACROSS OUR FAR SOUTHEAST COUNTIES...CLOSER TO
THE BOUNDARY. FURTHER NORTH...THE BAND OF MID LEVEL CLOUDS AND
SPRINKLES WAS BEGINNING TO DECREASE IN COVERAGE ACRS THE AREA
AS WEAK HIGH PRESSURE BUILDS IN FROM THE NORTH. WITH THE
LIGHT WIND FLOW OVERNIGHT AND COPIOUS AMOUNTS OF LOW LEVEL
MOISTURE...SOME PATCHY DENSE FOG WILL DEVELOP LATER TONIGHT.
WILL INCLUDE THE FOG MENTION IN THE GRIDS FOR THE OVERNIGHT
HOURS. HAVE ALREADY SENT OUT AN UPDATE WITH THE WORDING ADJUSTMENT
IN THE PRECIP TONIGHT ACRS THE SOUTHEAST...WILL SEND OUT ANOTHER
UPDATE TO INCLUDE THE FOG IN PARTS OF OUR AREA OVERNIGHT.

SMITH

.AVIATION...
ISSUED 600 PM CDT FRI JUL 29 2011

ISOLATED SHOWER THREAT THIS EVENING...THEN THE MAIN FORECAST
CONCERN WILL BE WITH LATE NIGHT FOG. LATEST SURFACE ANALYSIS
HAS A WEAK COOL FRONT SOUTH OF THE TAF SITES LATE THIS AFTERNOON
AND EXPECT THIS BOUNDARY TO CONTINUE TO SLIDE SOUTH THIS EVENING.
STILL HAVE SOME MVFR CIGS AT BMI AND PIA BUT EXPECT THOSE TO
GIVE WAY TO SOME VFR CIGS THIS EVENING AS SOME MID LEVEL CLOUDS
TRACK ACRS THE AREA. CLOUDS SHOULD MOVE OUT LATE TNT ALLOWING
FOR THE PSBLTY OF SOME MVFR VSBYS IN FOG AFTR 08Z. ANY FOG THAT
DEVELOPS OVERNIGHT SHOULD QUICKLY BURN OFF SATURDAY MRNG AS
SLIGHTLY DRIER AIR ADVECTS IN FROM THE NORTH. SURFACE WINDS
TONIGHT WILL BE LIGHT...MOSTLY OUT OF A NORTHEAST TO EAST
DIRECTION...AND THEN EAST AT 10 KTS OR LESS ON SATURDAY WITH
VFR CONDITIONS EXPECTED.

SMITH

.PREV DISCUSSION...
ISSUED 300 PM CDT FRI JUL 29 2011

SHORT TERM...TONIGHT THROUGH MONDAY...
WEAK COLD FRONT HAS PROGRESSED TO A LINE FROM NEAR KEOKUK TO
LAFAYETTE. LATEST VISIBLE SATELLITE IMAGERY INDICATES SOME CU
DEVELOPING TO THE NORTH OF THE FRONT...BUT MOISTURE IS SHALLOW AND
INSTABILITY NOT NEARLY AS FAVORABLE AS FURTHER SOUTH. SCATTERED
STORMS HAVE DEVELOPED ALONG THE IA/MO BORDER WHERE INSTABILITY IS
GREATER...WITH LITTLE MOVEMENT SEEN IN THE SURFACE-BASED PORTION OF
THE PRECIPITATION. WITH A MORE HOSTILE AND CONVECTIVELY CONTAMINATED
ENVIRONMENT DOWNSTREAM OVER CENTRAL IL...WILL KEEP POPS BELOW
MENTION FOR THE FAR NORTH AFTER 00Z. MODEL DATA DOES NOT INDICATE
MUCH OF THIS ACTIVITY SURVIVING AS FAR EAST AS THE IL RIVER.
MEANWHILE...A DIFFERENTIAL HEATING BOUNDARY HAS EVOLVED SOUTH OF THE
THICK MID/HIGH CLOUD REMNANTS OF MORNING STORMS AND LIES FROM JUST
SOUTH OF ST. LOUIS TO TERRE HAUTE. MORE SUBSTANTIAL CU HAS BEEN
BUILDING IN THIS AREA WHERE MIXED-LAYER CAPE VALUES ARE AROUND 3000
J/KG AND CINH IS WEAK. DEEP-LAYER SHEAR IS NEGLIGIBLE THOUGH...SO
ANY SEVERE THREAT WILL BE FROM DOWNBURSTS DUE TO PRECIPITATION
LOADING. WILL KEEP HEALTHY CHANCE POPS GOING DOWN THERE AS SHORT
RANGE RADAR SIMULATIONS DEVELOP DEEP MOIST CONVECTION LATER THIS
AFTERNOON AND EVENING.

ALTHOUGH SOMEWHAT COOLER AIR WILL BE COMING SOUTH WITH THE FRONT...
SURFACE DEWPOINTS WILL REMAIN FROM THE UPPER 60S TO MIDDLE 70. SOME
AREAS MAY FOG UP WHERE SKIES CLEAR LATER TONIGHT. THIS SHOULD BE
MAINLY AN AVIATION HAZARD SO WILL NOT MENTION IN PUBLIC GRIDS UNLESS
WIDESPREAD VISIBILITIES BELOW A MILE BECOME LIKELY. BY SATURDAY
MORNING...SUFFICIENT PRE-FRONTAL MOISTURE/INSTABILITY FOR STORMS
WILL BE RESTRICTED TO AREAS ALONG/SOUTH OF INTERSTATE 70.

ONCE THE FRONT SINKS SOUTH OF THE FORECAST AREA SATURDAY EVENING...A
PERIOD OF DRY WEATHER WILL TAKE HOLD FOR SUNDAY THROUGH MONDAY. AS
MENTIONED ABOVE...THE COLD FRONT WILL BE RATHER WEAK...SO ALTHOUGH
DEWPOINTS WILL BE SOMEWHAT DRIER...AIR TEMPERATURES WILL STILL GET
INTO THE UPPER 80S TO LOWER 90S. HEAT INDEX VALUES SHOULD REMAIN
BELOW ADVISORY/WARNING CRITERIA.

LONG TERM...TUESDAY THROUGH FRIDAY...
WARM UP WILL BEGIN IN ERNEST ON TUESDAY AHEAD OF THE NEXT COLD FRONT
THAT WILL BE ENTERING THE MIDWEST LATE TUESDAY AND TUESDAY NIGHT.
LOW LEVEL WARM ADVECTION ON SOUTHWESTERLY LOW LEVEL FLOW WILL BOOST
HIGH TEMPERATURES WELL INTO THE 90S. DEWPOINTS IN THE LOW TO MID 70S
WILL CREATE HEAT INDEX VALUES 105 TO 110...AND AN ADVISORY MAY BE
REQUIRED IN SUBSEQUENT FORECASTS.

THE PERSISTENT UPPER RIDGE COVERING MOST OF THE CENTRAL AND SOUTHERN
PARTS OF THE COUNTRY WILL WEAKEN SOMEWHAT AND BECOME FLATTER. THE
MAIN BELT OF WESTERLIES WILL CONTINUE TO BE LOCATED OVER THE
INTERNATIONAL BORDER REGION WITH CANADA. THE FRONT MOVING INTO THE
AREA LATE TUESDAY WILL MOVE SOUTH INTO SOUTHERN IL BEFORE STALLING
OUT AS IT ENCOUNTERS LIGHT PARALLEL FLOW ALOFT CLOSER TO THE RIDGE.
THUNDERSTORM CHANCES WILL INCREASE WITH THE APPROACH OF THE FRONT...
WITH SCATTERED PRECIPITATION POSSIBLY HANGING AROUND A FEW DAYS
DEPENDING ON WHERE THE FRONT COMES TO A HALT. THIS IS ASSUMING THE
FRONT DOES INDEED TURN STATIONARY OVER SOUTHERN IL. A MINORITY OF
THE LONGER RANGE MODELS REBUILD THE UPPER RIDGE TO THE WEST AND
PLACES THE MIDWEST WITHIN NORTHWESTERLY FLOW...WHICH WOULD GIVE A
FURTHER SOUTHWARD PUSH TO THE FRONT. SINCE A FLATTER RIDGE IS THE
PREFERRED SOLUTION AT THIS TIME...WILL HAVE CHANCE AND SLIGHT CHANCE
POPS BEGINNING LATE TUESDAY AND CONTINUING THROUGH THURSDAY.
