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 La Crosse, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at May 2, 3:51 PM CDT, 1 hour 13 minutes earlier.

Area forecast discussion, May 2, 3:51 PM CDT, 1 hour 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
351 PM CDT FRI MAY 2 2008

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT

SEVERE WEATHER POSSIBILITY LATE THIS AFTERNOON AND EARLY EVENING...
AND SNOW POSSIBILITIES LATE TONIGHT AND SATURDAY MORNING ARE THE
PRIMARY CONCERNS WITH THIS PART OF THE FORECAST.

AT 3 PM...A STRONG LOW PRESSURE SYSTEM WAS LOCATED ACROSS SOUTH
CENTRAL MINNESOTA. A WARM/OCCLUDED FRONT EXTENDED FROM SHEBOYGAN
WISCONSIN TO AUSTIN MINNESOTA. NORTH OF THIS FRONT...THE
TEMPERATURES RANGED FROM THE MID 40S TO MID 50S. MEANWHILE
TEMPERATURES WERE IN THE 60S AND 70S SOUTH OF THIS FRONT. RESIDUAL
CLOUDS FROM THIS MORNINGS SHOWERS AND THUNDERSTORMS HAS LIMITED
THE RECOVERY OF INSTABILITY IN THE WARM SECTOR OF THIS
SYSTEM. AS OF 02.19Z...THERE WAS A NARROW BAND OF SURFACE BASED
CAPES IN THE EXCESS OF 500 J/KG FROM DUBUQUE TO MASON CITY. THE
EFFECTIVE SHEAR IS RUNNING AROUND 30 KNOTS. THERE WAS A FEW
FUNNEL CLOUD REPORTS ACROSS NORTHEAST IOWA EARLIER IN THE AFTERNOON.
IN ADDITION...A 52 KNOT WIND GUST WAS REPORT AT A SCHOOL NET IN
MASON CITY AT 308 PM.

THE 02.18Z RUC IS CONTINUING TO SHOW THAT A NARROW RIBBON OF MOST
UNSTABLE CAPES BETWEEN 500 TO 800 J/KG WILL MOVE ACROSS NORTHEAST
IOWA...SOUTHEAST MINNESOTA...AND SOUTHWEST...WEST CENTRAL...AND
CENTRAL WISCONSIN LATE THIS AFTERNOON AND EVENING. BOTH THE 0-3 KM
AND 0-6 KM SHEAR ARE RUNNING AROUND 30 KNOTS. WITH QUITE A BIT OF
CLOUD COVER...IT LOOKS LIKE WE WILL HAVE A VERY LIMITED TIME
PERIOD FOR ANY SEVERE WEATHER. WE WILL HAVE TO WATCH THIS CLOSELY
THIS EVENING...BUT AT THIS TIME IT LOOKS LIKE IT WILL NOT BE A
WIDESPREAD EVENT. IT CONTINUES TO LOOK LIKE THE THREAT FOR ANY
THUNDERSTORMS SHOULD BE OVER BY 8 PM THIS EVENING.

BEHIND THIS SYSTEM...NORTHWEST WINDS WILL GUST INTO THE 20 TO
30 MPH RANGE...AND THERE WILL BE STRONG COLD AIR ADVECTION. WITH
THE MODELS CONTINUING TO SHOW THAT THE 850 MB TEMPERATURES WILL
FALL INTO THE -2C TO 0C RANGE LATE TONIGHT AND SATURDAY MORNING.
AS THE DEFORMATION BAND MOVES EAST ACROSS THE AREA. THE RAIN WILL
OCCASIONALLY CHANGE OVER SNOW AT TIMES. WITH TEMPERATURES ABOVE
FREEZING...I AM NOT EXPECTING ANY ACCUMULATIONS. HOWEVER IF THE
RATES ARE HIGH ENOUGH...YOU MAY SEE A BRIEF ACCUMULATION...BUT IT
WILL THEN MELT QUICKLY.

IT CONTINUES TO LOOK LIKE THE FRONTOGENETIC FORCING WILL QUICKLY
WEAKEN ON SATURDAY AFTERNOON. AS A THIS OCCUR...THE DEFORMATION
BAND OF PRECIPITATION WILL QUICKLY DISSIPATE.

.LONG TERM...MONDAY THROUGH FRIDAY

THE MEDIUM RANGE MODELS CONTINUE TO STRUGGLE WITH THE TIMING AND
LOCATIONS OF A SERIES OF TROUGHS MOVING EASTWARD ACROSS THE UNITED
STATES DURING THIS TIME PERIOD. THE RUN TO RUN CONSISTENCY HAS NOT BEEN
THAT GREAT DURING THE PAST SEVERAL DAYS. AS A RESULT...THERE IS
VERY LITTLE CONFIDENCE IN THIS PART OF THE FORECAST.

ONE OF THE FEW THINGS THAT HAS BEEN CONSISTENTLY SHOWING UP IN THE
MODELS IS A CHANCE OF SHOWERS ON MONDAY ACROSS NORTH CENTRAL AND
CENTRAL WISCONSIN AS A COLD FRONT MOVES THROUGH THE REGION. SINCE
THIS HAS BEEN A CONSISTENT SIGNAL...I HAVE ADDED A SMALL CHANCE OF
PRECIPITATION FOR THIS TIME PERIOD.

ONE THING THAT IS INTERESTING IS THAT THE 02.12Z GFS AND ECMWF ARE
NOW IN AGREEMENT THAT A TROUGH WILL MOVE THROUGH THE REGION ON
TUESDAY AND TUESDAY NIGHT. I CURRENTLY HAVE A 20 TO 30 PERCENT
CHANCE OF SHOWERS DURING THIS TIME PERIOD. IF THIS TREND CONTINUES...
WE WILL HAVE TO RAISE THESE PROBABILITIES A BIT HIGHER OVER THE
WEEKEND.

&&

.AVIATION...LATE THIS AFTERNOON THROUGH SATURDAY MORNING

STRONG AREA OF LOW PRESSURE WILL MOVE FROM WESTERN IA INTO WEST
CENTRAL WI BY EARLY THIS EVENING. THIS WILL SWING A COLD FRONT
NORTHEAST INTO THE AREA THIS AFTERNOON WITH A BROKEN LINE OF
SHRA/TS. A FEW OF THESE STORMS MAY BECOME SEVERE WITH DAMAGING WINDS AND
HAIL. INCLUDED 2SM +TSRA WITH GUSTS TO 40 MPH AT THE KRST/KLSE TAF
SITES IN THE 20-22Z TIME FRAME. THE COLD FRONT AND ANY LINGERING
SHRA ACTIVITY WILL EXIT NORTHEAST OF THE AREA BY 03Z THIS EVENING.
BEHIND THE COLD FRONT AND SHRA ACTIVITY...CONDITIONS ARE EXPECTED TO
IMPROVE INTO VFR/MVFR CATEGORY. AS THE LOW MOVES INTO NORTHERN WI/UPPER
MICHIGAN TOWARD MORNING...WINDS WILL SHIFT AND BECOME GUSTY FROM THE
NORTHWEST. COLDER AIR FILTERING INTO THE AREA ON NORTHWEST WINDS
WILL PRODUCE A MIXTURE OF -SHRASN AFTER 08Z...WITH CIGS LOWERING
INTO MVFR RANGE.
