Verified. The Iowa Environmental Mesonet's Cow matched 3 storm reports to this severe thunderstorm warning; the first came 18 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 Duluth, MN wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 1:44 PM CDT, 23 minutes earlier.

Area forecast discussion, May 22, 1:44 PM CDT, 23 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DULUTH MN
144 PM CDT SUN MAY 22 2011

.UPDATE...STACKED SFC/MID LVL LOW ROTATING SLOWLY NE INTO SWRN MN
THIS AFTN. SFC WARM FRONT ACROSS SRN MN WORKING NORTH. INITIAL
BAND OF CONVECTION STRETCHING ACROSS SRN TIER OF CWA IN MARGINALLY
UNSTABLE ATMOSPHERE. STORMS APPROACHING THRESHOLD OF SVR HAIL AND
WILL BE MONITORED CLOSELY ACROSS SRN WISC ZONES NEXT FEW HRS.
ADDITIONAL SPOKES OF CONVECTION SHOULD ROTATE NORTHWARD AS
SYNOPTIC SCALE SYSTEM MOVES NNE THIS EVENING. LATEST NMMWRF SIM
REFL INDICATES INCREASING POTENTIAL FOR SVRWX ACROSS SRN TIER OF
ZONES WITH HAIL/DMG WIND PRIMARY THREAT. POTENTIAL FOR MORE SFC
BASED ROTATION MAY ARISE BY LATE TODAY/EARLY EVENING FROM NEAR BRD
LAKES REGION EAST INTO SRN TIER OF WISC ZONES WHERE LOW LVL BOUNDARIES
PROVIDE ENHANCED SHEAR. DENSE FOG STILL LOCALIZED AT LAKEFRONT IN
TWIN PORTS VICINITY...AND ALONG NSHORE IN COOK COUNTY. HAVE
ADJUSTED POPS/SKY/WX GRIDS TO ACCOUNT FOR QUICK MOVING AREAS OF
PRECIP/CLEARING THRU AFTN HRS.

&&

.PREV DISCUSSION... /ISSUED 118 PM CDT SUN MAY 22 2011/

AVIATION.../18Z TAF ISSUANCE/
A CHAOTIC ARRAY OF CLOUD HEIGHTS AND VSBYS WILL BE FOUND ACROSS
THE NORTHLAND OVER THE TAF PERIOD. AS LOW PRESSURE WRAPS UP AND
EVOLVES IT WILL BRING BANDS OF SHOWERS AND THUNDERSTORMS THROUGH
THE REGION. CIGS/VSBYS WILL BE HIGHLY VARIABLE BETWEEN VFR AND
MVFR...WITH LOCALIZED AREAS OF IFR MAINLY TONIGHT AND EARLY
MONDAY. RAIN AND THUNDERSTORMS WILL ALSO REDUCE VISIBILITIES TO
MVFR/IFR AT TIMES.

PREV DISCUSSION... /ISSUED 629 AM CDT SUN MAY 22 2011/

AVIATION...12Z TAFS.
DIFFICULT FORECAST WITH THE APPROACH OF THE LARGE OCCLUDED LOW
PROGGED TO MOVE THROUGH THE AREA THROUGH THE NEXT 24 HOURS.
CONFIDENCE IS LOW WITH THIS SET OF FORECASTS AS TIMING OF TSRA AND
THEIR ASSOCIATED VSBY AND CIG RESTRICTIONS. GUSTY SFC WINDS WILL
OCCUR IN THE VCNTY OF STRONGER STORMS.

PREV DISCUSSION... /ISSUED 330 AM CDT SUN MAY 22 2011/

DISCUSSION...
A VERTICALLY STACKED LOW SEEN ON WV SAT IMAGERY ROTATING OVER SOUTH
DAKOTA WILL TRACK EAST-NORTHEAST ACROSS CENTRAL MN THROUGH THE
DAY...LIFTING OVER WRN LK SUPERIOR OVERNIGHT. AHEAD OF THE LOW
OVER MN/WIS...AN OCCLUDED FRONT IN THE REGION OF MAX PVA HAS
TRIGGERED SHRA/TSTMS THAT HAVE TRACKED N OVERNIGHT THROUGH THE SRN
ZONES OF THE DLH CWA. ATTM...THE ONLY REPORTS FROM THESE STORMS
WERE OF LOTS OF DIME/NICKLE SIZE HAIL IN THE BRD AREA. THE STORMS
MAY WEAKEN/DIMINISH FOR A PERIOD AROUND DAY BREAK. HOWEVER...NAM
BUFR SOUNDINGS AND SHORT RANGE SIMULATED REF HAVE CONSISTENTLY
SHOWN THAT THE STORMS WILL REDEVELOP IN THE 16-18Z TIME FRAME.
THE COOLER AIR ALOFT ASSOCIATED WITH THE LOW WILL RESULT IN STEEP
LAPSE RATES/LARGE LI VALUES AND 1000-2000 J/KG OF CAPE FOR MUCH OF
THE NORTHLAND. THE BEST INSTABILITY/SHEAR AND GREATEST SVR THREAT
WILL BE OVER WISCONSIN TODAY WHERE DEW POINTS ARE ALREADY IN THE
LOW 60S AND SOUNDINGS SHOW LIFTED INDEX VALUES REACH NEGATIVE 8
WITH SFC BASED CAPE IN EXCESS OF 2000-2500 J/KG.

WENT WIDESPREAD SHRA/TSTMS LIKELY TODAY WITH SVR MENTION OVER MUCH
OF THE CWA WITH THE EXCEPTION OF BORDERLAND ZONES AND NEAR LAKE
SUPERIOR. DENSE FOG WILL PERSIST NEAR LAKE SUPERIOR THROUGH
DAYBREAK...GRADUALLY DIMINISHING THROUGH MID DAY.

OTHER CONCERN IS HEAVY RAIN AS THE LOW TRACKS OVER THE FA THIS
AFTERNOON/OVERNIGHT. THE LATEST MDLS RUNS ARE IN DECENT AGREEMENT
THAT A HEAVY RA BAND...CO-LOCATED WITH THE LOW...LIFTS NE OVER
THE CWA THROUGH 12Z MON. ALTHOUGH THE PRECISE TRACK IS SOMEWHAT
UNCERTAIN...INCREASED QPF WITH ADDITIONAL RAINFALL AMOUNTS
TODAY/NIGHT OF GENERALLY 0.50-1.0 INCHES. THERE MAY BE AREAS THAT
RECEIVE AMOUNTS CLOSER TO 1.5 INCHES. SOUNDINGS ALSO SUPPORT HEAVY
RAIN OVERNIGHT WITH DEEPLY SAT PROFILES...A FEW HUNDRED JOULES OF
CAPE AND PWATS AROUND 1.0 INCH.

EXTENDED...MONDAY NIGHT THROUGH SATURDAY.
COOL HIGH PRESSURE OVER WESTERN ONTARIO MONDAY NIGHT WILL DRIFT OVER
THE WESTERN GREAT LAKES INTO WEDNESDAY. ANOTHER AREA OF COOL HIGH
PRESSURE WILL REPLACE THE GREAT LAKES ONE WEDNESDAY NIGHT AND FOLLOW
THE SAME PATH TO THE WESTERN GREAT LAKES BY FRIDAY. SEASONAL
TEMPERATURES WILL PREVAIL. MODELS BEGIN TO DIVERGE BEYOND FRIDAY AND
HAVE MADE NO CHANGES.

PREV DISCUSSION... /ISSUED 1238 AM CDT SUN MAY 22 2011/

AVIATION...06Z TAFS.
DRIER AIR SPREADING IN FROM THE SOUTH ALOFT HAS RESULTED IN SOME
CLEARING OR SCATTERING OUT OF THE LOW CLOUDS ACROSS OUR SRN AND WRN
ZONES...WHILE LOW CLOUDS AND FOG PERSIST FROM THE TWIN PORTS NEWD
ALONG THE NORTH SHORE DUE TO ONSHORE FLOW. THIS PATTERN WILL CONTINUE
THROUGH MUCH OF THIS MORNING. THERE WILL CONTINUE TO BE A CHANCE OF
SHOWERS AND STORMS THROUGH THIS MORNING...MAINLY ACROSS OUR WRN AND
SRN ZONES AWAY FROM THE MARINE LAYER. THE MAIN LOW PRESSURE SYSTEM
AND ASSOCIATED OCCLUDED FRONT WILL THEN PROPAGATE OVER THE UPPER
MIDWEST ON SUNDAY. LIFT ASSOCIATED WITH THESE FEATURES COMBINED WITH
INCREASING INSTABILITY WILL RESULT IN THE DEVELOPMENT OF SCATTERED
THUNDERSTORMS ACROSS THE NORTHLAND ON SUNDAY...ESPECIALLY BY
AFTERNOON. THERE IS SLIGHT RISK OF SEVERE THUNDERSTORMS WITH LARGE
HAIL AND DAMAGING WINDS ACROSS NRN WI.
