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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
322 PM CDT SUN MAY 22 2011

.DISCUSSION...STACKED SFC/MID LVL LOW ROTATING SLOWLY NE INTO SWRN MN
THIS AFTN. SFC WARM FRONT ACROSS SRN MN WORKING NORTH. BANDS OF
CONVECTION ARE DEVELOPING AND MOVING ACROSS SRN HALF OF CWA IN
INCREASINGLY MORE UNSTABLE ATMOSPHERE. STORMS HAVE EXCEEDED SVR
HAIL THRESHOLD WITH REPORTS ON NEAR 1 INCH HAIL IN SRN ASHLAND
COUNTY. PUBLIC REPORTS OF WALL CLOUD JUST NW OF PARK FALLS WITHIN
PAST HOUR. FOG HAS PUSHED INLAND ONCE AGAIN NEAR TWIN PORTS AFTER
A BREAK EARLIER THIS AFTN.

THIS AFTN/EVENING...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 WILL CONTINUE THROUGH EARLY EVENING FROM
NEAR BRD LAKES REGION EAST INTO SRN TIER OF WISC ZONES WHERE LOW
LVL BOUNDARIES PROVIDE ENHANCED SHEAR. LATER THIS EVENING
DEFORMATION ZONE WILL PROVIDE AN AREA OF ENHANCED RAINFALL ACROSS
NRN HALF OF CWA...ROTATING INTO ARROWHEAD BY EARLY MORNING.

MONDAY...MID LVL TROF/LOW EJECTS EAST OF REGION TOMORROW.
ORGANIZED LIFT WITHIN DEFORMATION AXIS EXITS NE ZONES BY MIDDAY.
WILL TAPER POPS DOWNWARD AS DAY PROGRESSES. SECONDARY LOW LVL
BDRY... INDICATED IN SFC/925H THETAE FIELD... WILL CROSS CWA
DURING THE DAY WITH 85/70H RH DECREASING GRADUALLY. WILL MAINTAIN
LOW POPS THRU AFTN FOR MOST OF CWA EXCEPT NEAR BORDERLAND.

TUES/WED...WILL KEEP INHERITED DRY FCST FOR NOW AS CWA REMAINS UNDER
NEW MID LVL FLOW AND SFC HIGH PRESSURE. PRECIP SHOULD BE CONFINED TO
AREAS SOUTH OF CWA AS SRN BRANCH OF WESTERLIES FEATURES AMPLIFYING
TROF AND SFC CYCLOGENESIS.

.EXTENDED...WEDNESDAY NIGHT THROUGH SUNDAY. HIGH PRESSURE WILL BUILD
ACROSS THE REGION ON WEDNESDAY NIGHT AND THURSDAY...BRINGING COOLER
BUT DRY WEATHER TO THE REGION FOR MIDWEEK. DEFINITELY COULD SEE SOME
FROST/FREEZE HEADLINES DURING THAT TIME FRAME AS COOL CANADIAN AIR
SETTLES INTO THE WESTERN GREAT LAKES REGION. THE GFS BRINGS
PRECIPITATION BACK INTO THE REGION BY FRIDAY...WHILE THE ECMWF KEEPS
IT DRY ON FRIDAY AND FOR THE MOST PART FRIDAY NIGHT AS WELL. WILL
KEEP THINGS GENERALLY DRY LATE IN THE WEEK AND INTO THE
WEEKEND...BUT WILL HAVE TO REEVALUATE LATER RUNS TO SEE IF THERE IS
BETTER AGREEMENT CONCERNING POSSIBLE PRECIPITATION.

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
