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.

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 Apr 3, 2:05 PM CDT, 7 minutes earlier.

Area forecast discussion, Apr 3, 2:05 PM CDT, 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
205 PM CDT TUE APR 3 2007

.DISCUSSION...SEVERE WEATHER EVENT ONGOING ACROSS PORTIONS OF
FORECAST AREA...PRIMARILY ALONG AND SOUTH OF THE I-70 CORRIDOR AS OF
2 PM. LATEST SURFACE ANALYSIS HAD LOW PRESSURE CENTERED NEAR THE
IL/WI BORDER...WITH A STRONG COLD FRONT EXTENDING SOUTHWEST INTO THE
PLAINS. ALOFT...A VIGOROUS WAVE WAS DIVING ACROSS THE UPPER MIDWEST
AND GREAT LAKES. MAIN CONCERNS WITH THIS FORECAST REVOLVE AROUND
LINGERING CONVECTION THIS AFTERNOON/EVENING...THE STRENGTH OF THE
WINDS IN THE WAKE OF THE COLD FRONT...AND HOW COLD IT WILL BE OVER
THE NEXT SEVERAL DAYS.

12Z MODELS IN GOOD OVERALL AGREEMENT WITH RESPECT TO FEATURES
EXPECTED TO IMPACT REGION. GUIDANCE TEMPERATURES CLOSE/REASONABLE...
SO WILL GO WITH A BLEND.

SHORT TERM...TONIGHT THROUGH FRIDAY...

TONIGHT...SHOWERS/STORMS ALONG PRE FRONTAL TROF/OUTFLOW BOUNDARY
WILL QUICKLY END THIS EVENING. COLD FRONT WILL MOVE SOUTH/EAST OF
THE REGION THIS EVENING AS WELL...WITH STRONG WINDS EXPECTED IN THE
CAA/STRONG PRESSURE GRADIENT ON ITS BACKSIDE. GRADIENT SLACKENS
QUICK ENOUGH TONIGHT AND MIXING IS SHALLOW ENOUGH TO KEEP WINDS
BELOW ADVISORY CRITERIA. HOWEVER...IT WILL STILL BE WINDY...WITH
GUSTS OVER 30 MPH.

WEDNESDAY THROUGH FRIDAY...THE SURFACE LOW WILL SLOWLY LIFT TO THE
NORTHEAST...AS THE UPPER WAVE CARVES OUT AN UNSEASONABLY DEEP/COLD
TROF OVER THE EASTERN UNITED STATES. DRY WEATHER IS EXPECTED...BUT
COLD AIR ALOFT WILL ALLOW FOR A FAIR AMOUNT OF CLOUD COVER. WINDS
WILL INITIALLY BE RATHER BREEZY...BUT SHOULD DIMINISH WITH TIME AS
PRESSURE GRADIENT AND CAA WEAKEN.

SUB FREEZING TEMPS STILL LOOK LIKELY WED NIGHT AND THU NIGHT WITH
LOWS IN THE MID TO UPPER 20S. AVERAGE LAST SPRING FREEZE IN CENTRAL
IL IS MID APRIL SO HOLDING OFF ON FREEZE HEADLINES. BUT TEMPS HAVE
BEEN 15 TO 25F ABOVE NORMAL DURING THE PAST TWO WEEKS ALLOWING SOME
VEGETATION TO GROW VERY EARLY THIS SEASON. LAST TIME WE HAD LOWS IN
THE 20S WAS MARCH 18. TENDER VEGETATION WILL NEED TO BE COVERED OR
TAKEN INDOORS.

LONG TERM...SATURDAY THROUGH TUESDAY...MODELS/ENSEMBLES IN
REASONABLE AGREEMENT WITH THE UNSEASONABLY COOL RIDGE WEST/TROF EAST
PATTERN THAT WILL BE IN PLACE TO START THE PERIOD. THE FLOW IS
EXPECTED TO DEAMPLIFY WITH TIME AND PROVIDE MODERATING TEMPERATURES
BY THE END OF THE PERIOD. GENERALLY DRY WEATHER IS EXPECTED WITH NO
STRONG SIGNAL FOR PRECIPITATION AT THIS POINT...BUT THE RISK FOR
PRECIPITATION WITH ANY WAVES DIVING INTO THE MEAN TROF WILL NEED TO
BE WATCHED.
