The radar

The Lincoln radar (KILX), 72 km from the middle of the area, began a volume at 16:48 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 12:00Z, 4.8 hours before the alert went out and 108 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.

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 Jul 24, 10:12 AM CDT, 1 hour 36 minutes earlier.

Area forecast discussion, Jul 24, 10:12 AM CDT, 1 hour 36 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1012 AM CDT SUN JUL 24 2011

.DISCUSSION...
ISSUED 1012 AM CDT SUN JUL 24 2011

SEVERAL CONCERNS EXIST IN THE SHORT TERM. ZONES/GRIDS WERE
RECENTLY UPDATED TO UPDATE THE RAIN CHANCES OVER THE CWA...AS WELL
AS THE WINDS DUE TO THE NUMEROUS OUTFLOW BOUNDARIES OVER THE AREA.
NO CHANGES WERE MADE TO THE EXCESSIVE HEAT WARNING AT THIS
TIME...BUT AM CONCERNED ABOUT TEMPERATURES RECOVERING ENOUGH
ACROSS THE NORTHERN CWA TO JUSTIFY A CONTINUATION IN THAT AREA.

MCS AND ASSOCIATED LINE/BOWING SEGMENT EXTENDING FROM NORTHWEST
INDIANA TO AROUND CHAMPAIGN AND MONTICELLO. CLOUD TOPS ON IR
IMAGERY HAVE BEEN COOLING OVER THE LAST FEW HOURS...AND SURFACE
REPORTS ARE INDICATING AROUND 40 MPH GUSTS WITH THE STORMS AS WELL
AS ALONG THE GUST FRONT AHEAD OF IT. MORE DISORGANIZED
SHOWERS/STORMS PUSHING IN FROM THE WEST...ALTHOUGH IR IMAGERY
SHOWING CLOUD TOPS COOLING TO AROUND -70C NORTH OF PEORIA.

.AVIATION...
ISSUED 619 AM CDT SUN JUL 24 2011

VFR CONDITIONS CAN BE EXPECT AT ALL SITES THROUGH TODAY AND INTO
THIS EVENING. SOME LIGHT FOG IS POSSIBLE THIS MORNING AT
PIA/BMI/CMI...BUT ONLY ENOUGH TO WARRANT A TEMPO GROUP. AFTER SOME
RAINFALL TODAY...LIGHT FOG WILL DEFINITELY BE POSSIBLE AT ALL
SITES OVERNIGHT SO HAVE ADDED 4SM BR AT ALL SITES STARTING AT 07Z.
AS A COLD FRONT MOVES THROUGH THE REGION TODAY...THUNDERSTORMS
WILL BE POSSIBLE BEGINNING LATE THIS MORNING AT PIA/BMI AND THEN
BEGINNING EARLY THIS AFTERNOON AT SPI/DEC/CMI. DUE TO THE SLOW
NATURE OF THE FRONT...STORMS WILL REMAIN AROUND THE SITES INTO THE
EVENING HOURS. SINCE ACTUAL TIMING OF STORMS AT EACH SITE IS
UNCERTAIN...WILL JUST HAVE VCTS AT ALL SITES FOR AROUND 8HRS.
AFTER THE STORMS/FROPA...SOME LOW VFR BKN CLOUDS WILL BE POSSIBLE
FOR THE REMAINDER OF THE EVENING HOURS...THEN CLOUDS WILL SCATTER
OUT AND LIGHT FOG WILL DEVELOP. WINDS WILL BE LIGHT THROUGH THE
PERIOD...BUT GENERALLY OUT OF THE SOUTH TO SOUTHWEST TODAY AND
THIS AFTERNOON...THEN BECOME NORTHWEST ONCE THE FRONT MOVES
THROUGH AND THEN LIGHT AND VARIABLE AGAIN LATE TONIGHT.

.PREV DISCUSSION...
ISSUED 316 AM CDT SUN JUL 24 2011

FORECAST STORY REMAINS THE SAME...HOT AND HUMID THROUGH TOMORROW.
AND THOUGH AN APPROACHING COOL FRONT WILL GIVE A BIT OF AN AIRMASS
SHIFT FOR TUESDAY...IT WILL STILL BE HOT...JUST A LITTLE LESS SO.
MAIN ISSUES FOR THE FORECAST RUN WILL BE HEAT...SCT TS THROUGH
TODAY AND TONIGHT WITH THE FRONT...AND THE DURATION OF THE PATTERN
SHIFT OVERALL AS MODELS RETURN TO A HIGH/UPPER RIDGE DOMINATING
THE SERN CONUS THROUGH MID WEEK...KEEPING HOT TEMPS OVER CENTRAL
ILLINOIS FOR A BIT LONGER.

SHORT TERM...TODAY AND TONIGHT...
TEMPS ONCE AGAIN IN THE 90S...AND HI IN EXCESS OF 105 AT PEAK
HEATING IN THE AFTERNOON. WEAK BOUNDARY AND WAVE OUT TO THE WEST
OVER NWRN MO PREV PROGGED TO BRING PRECIP TO CENTRAL ILLINOIS.
MODELS INITIALIZED VERY BADLY ACROSS THE BOARD WITH THE EXISTING
PRECIP...AND WILDLY OVERDONE. CONVECTIVE INITIATION/EVOLUTION...AND
THE MIDLEVELS AS A WHOLE...ARE A BIT OF A MESS AS A RESULT.
WIDESPREAD CHANCE POPS REMAIN AS THE BOUNDARY SLOWLY GETS
REINFORCEMENT FROM A DEEPENING WAVE FURTHER OUT IN THE PLAINS THIS
MORNING ON WV IMAGERY. THIS WAVE WILL HELP WITH A BRIEF OVERALL
PATTERN SHIFT TO MORE NWRLY FLOW...AND COOLER TEMPS FOR TUES. BUT
FOR TODAY AND TONIGHT...THE PUSH WILL BRING THE BEST CHANCES FOR
PRECIP ALONG ANY MESOSCALE BOUNDARIES FROM SCT CONVECTION.
PARTICULARLY THIS AFTERNOON AND EVENING.

LONG TERM...MONDAY THROUGH THURSDAY...
HIGH PRESSURE DOMINATES ONCE AGAIN WITH THE TEMPS MONDAY
AND TUESDAY LINGERING RIGHT AROUND 90. THOUGH STILL HOT...THE
HUMIDITY IS SLIGHTLY LESS...AND SO FAR TEMPS AND HEAT INDICES ARE
STAYING BELOW 105...WHICH IS WHY THE EXCESSIVE HEAT WARNING IS NOT
CONTINUED. HIGH PRESSURE BUILDS RIGHT BACK IN...WITH THE UPPER
RIDGE AXIS OVER IL AND BUILDS THE HEAT RIGHT BACK IN THROUGH THU.
MAIN CONCERN IN THE LONGER TERM WILL BE ADDITIONAL WAVES CRESTING
OVER THE RIDGE BRINGING PRECIP AND MORE SYSTEMS JUST TO THE NORTH
OF THE FA. AS A RESULT OF ONE OF THESE APPEARING IN THE
MODELS...SOME SILENT 20S FOR THU/THU NIGHT...BUT NOT WILLING TO
POP MORE THAN THAT AT THIS POINT AS THE COVERAGE WILL BE SKETCHY
AT BEST.
