Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 6 minutes after it went out.

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 La Crosse, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at Oct 23, 3:10 PM CDT, 2 hours 37 minutes earlier.

Area forecast discussion, Oct 23, 3:10 PM CDT, 2 hours 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
310 PM CDT SUN OCT 23 2011

.SHORT TERM...THROUGH TUESDAY NIGHT
310 PM CDT SUN OCT 23 2011

MAIN FORECAST CONCERN IS WITH THE RAIN CHANCES MONDAY NIGHT INTO
TUESDAY NIGHT.

SURFACE ANALYSIS THIS AFTERNOON SHOWS AN AREA OF LOW PRESSURE OVER
WESTERN ONTARIO WITH A TROUGH OF LOW PRESSURE/WIND SHIFT LINE
STRETCHING TO THE SOUTH THROUGH WESTERN WISCONSIN INTO WESTERN IOWA.

WATER VAPOR SATELLITE SHOWING A RATHER POTENT SHORT WAVE TROUGH
MOVING ACROSS NORTHERN MINNESOTA. THE FORCING FROM THIS WAVE IS
RESPONSIBLE FOR THE LINE OF SHOWERS AND ISOLATED THUNDERSTORMS
ALONG THE WIND SHIFT LINE FROM EASTERN MINNESOTA INTO NORTHEAST
IOWA. THE WAVE WILL CONTINUE TO MOVE EAST THROUGH THE EVENING AND
IS EXPECTED TO REACH LOWER MICHIGAN BY 06Z. THE WIND SHIFT LINE IS
EXPECTED TO MOVE EAST AT ABOUT THE SAME SPEED. WITH THIS
MOVEMENT...THE LINGERING SHOWERS ALONG THE WIND SHIFT LINE ARE
EXPECTED TO BE LIMITED TO THE EASTERN PARTS OF THE FORECAST AREA
AND WILL CARRY SCATTERED SHOWERS FOR AREAS ALONG AND EAST OF THE
MISSISSIPPI RIVER. DID CARRY THESE THROUGH 06Z BUT WOULD NOT BE
SURPRISED IF THESE CLEAR OUT OF THE FORECAST BETWEEN 02 AND 04Z.

ONCE THIS SYSTEM GOES BY...RIDGE ALOFT WILL BUILD OVER THE AREA
FOR MONDAY BEFORE FLATTENING OUT AS THE NEXT SHORT WAVE TROUGH
COMES IN. THIS WAVE WILL BE IN THE NORTHERN PART OF A POSITIVE
TILT LONG WAVE TROUGH. AS THE WAVE COMES IN...IT IS EXPECTED TO
PRODUCE AROUND 4 PVU/S OF VORTICITY ADVECTION IN THE 500-300 MB
LAYER. AN AREA OF SURFACE LOW PRESSURE SHOULD DEVELOP OVER
NEBRASKA MONDAY NIGHT WITH A WARM FRONT STRETCHING EAST INTO
SOUTHERN WISCONSIN. AS THE WAVE MOVES EAST...THE SURFACE LOW IS
EXPECTED TO TRACK EAST ALONG THE WARM FRONT REACHING SOUTHERN
WISCONSIN LATE TUESDAY AFTERNOON. A WEST TO EAST BAND OF MODERATE
FRONTOGENESIS IN THE 1000-500 MB LAYER IS EXPECTED TO DEVELOP NORTH OF
WARM FRONT ACROSS SOUTHERN MINNESOTA INTO CENTRAL WISCONSIN. THE
LIFT FROM THE FRONTOGENESIS WILL COINCIDE WITH BEST ISENTROPIC UP
GLIDE WITH 23.12Z NAM SHOWING UP TO 10 UBAR/S ON THE 295K SURFACE.
DESPITE RELATIVELY WEAK FORCING FROM THE SHORT WAVE TROUGH
ITSELF...THE LOW LEVEL THERMODYNAMICS ARE EXPECTED TO BE STRONG
ENOUGH TO PRODUCE A BAND OF LIGHT TO MODERATE RAIN NORTH OF THE
WARM FRONT. THIS RAIN SHOULD START TO MOVE IN/DEVELOP OVER THE
AREA AFTER 06Z TUESDAY AND WILL CARRY 50 PERCENT CHANCES OVER THE
NORTHEAST PORTIONS OF THE FORECAST AREA. WITH THE BEST
FRONTOGENESIS AND ISENTROPIC UP GLIDE EXPECTED TUESDAY
MORNING...WILL HAVE 60 TO 70 PERCENT CHANCES ALONG AND NORTHEAST
OF I94 AND THEN DROPPING DOWN TO A MAXIMUM OF 60 PERCENT TUESDAY
AFTERNOON AS THE FORCING STARTS TO SHIFT EAST. ANY LINGERING RAIN
TUESDAY EVENING SHOULD BE LIMITED TO THE EASTERN SECTIONS AND WILL
JUST CARRY A 20 TO 40 PERCENT CHANCE THROUGH 06Z WEDNESDAY.

.LONG TERM...WEDNESDAY THROUGH SUNDAY
310 PM CDT SUN OCT 23 2011

ONCE THIS SYSTEM MOVES BY...THE MODELS SUGGEST ANOTHER WAVE OF LOW
PRESSURE WILL MOVE ALONG THE BAROCLINIC ZONE IN ASSOCIATION WITH
THE NEXT SURFACE LOW. BY THIS TIME...THE BAROCLINIC ZONE IS
EXPECTED TO BE DOWN IN THE OHIO RIVER VALLEY SO THE SURFACE LOW
WILL TRACK WELL TO THE SOUTH OF THE AREA. THE RAIN ON THE NORTH
SIDE OF THIS LOW MAY GET CLOSE TO THE SOUTHERN SECTIONS OF THE
FORECAST AREA BUT DID STAY WITH A DRY FORECAST FOR WEDNESDAY. ALL
THE MODELS THEN SHOW A TROUGH OF LOW PRESSURE COMING THROUGH
FRIDAY. THE 23.12Z GFS AND GEM KEEP ANY PRECIPITATION WELL TO THE
NORTH ACROSS CANADA WHILE THE 23.12Z ECMWF DOES SHOW SOME ACROSS
NORTHERN MINNESOTA AND WISCONSIN. THIS IS A NORTHWARD SHIFT FROM
THE 23.00Z RUN AND WILL JUST HAVE A SMALL CHANCE ACROSS THE NORTH.
AFTER THAT...NEXT WEEKEND LOOKS DRY AT THIS TIME.

&&

.AVIATION...TODAY AND TONIGHT
1234 PM CDT SUN OCT 23 2011

A COLD FRONT COMBINED WITH AN UPPER LEVEL DISTURBANCE MOVING
SOUTHEAST ACROSS THE AREA THIS AFTERNOON WILL PRODUCE SCATTERED
SHOWERS AND ISOLATED THUNDER. THERE ARE SOME INDICATIONS THAT A FEW
OF THESE STORMS COULD BE STRONG ENOUGH TO PRODUCE SOME SMALL HAIL
ALONG WITH GUSTY WINDS...BUT ARE EXPECTED TO REMAIN BELOW SEVERE
LIMITS. FELT CONFIDENT ENOUGH TO INCLUDE TEMPO SHRA GROUP IN THE
KRST/KLSE TAFS THROUGH 22Z THIS AFTERNOON. HOWEVER...DUE TO THE
ANTICIPATED ISOLATED/WIDELY SCATTERED NATURE OF THE THUNDERSTORMS...
OPTED JUST TO CARRY A CB REMARK FOR NOW IN THE TAFS. LOOK FOR THIS
COLD FRONT TO EXIT EAST OF THE AREA THIS EVENING AROUND 00Z WITH
CLOUDS SCATTERING OUT FROM WEST TO EAST. WAS INITIALLY CONCERNED ABOUT
RIVER VALLEY FOG AT THE KLSE TAF EARLY MONDAY MORNING AS WINDS
DECOUPLE AND A RELATIVELY MOIST GROUND IS EXPECTED FROM TODAY/S
RAINFALL...BUT RUC/NAM BUFKIT SOUNDINGS SHOW WINDS AT BLUFF-TOP
REMAINING ABOVE 10KT WHICH WOULD ACT TO PRODUCE SOME RIVER CHANNEL
STRATUS INSTEAD OF FOG. HAVE THEREFORE INCLUDED SCT003 IN THE KLSE
TAF FROM 24.08Z THROUGH 24.14Z. WILL CONTINUE TO WATCH THIS CLOSELY.
MORE RAINFALL WOULD INCREASE THE GROUND MOISTURE AND FUEL FOR MORE
FOG...STRATUS DEVELOPMENT. OTHERWISE...VFR CONDITIONS ARE IN THE
TAFS THROUGH THE PERIOD.
