Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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 tornado 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 tornado warning went out at Jul 30, 3:48 PM CDT, 2 hours 29 minutes earlier.

Area forecast discussion, Jul 30, 3:48 PM CDT, 2 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
348 PM CDT SAT JUL 30 2011

.DISCUSSION...MAIN SHORT TERM FOCUS IS SEVERE POTENTIAL.

AS OF 330 PM...THE STORMS HAD MOVED EAST OUT OF THE CWA WITH DRY
WEATHER ACROSS THE ENTIRE CWA. THINGS HAD STABILIZED SOMEWHAT
BEHIND THE INITIAL AREA OF SHOWERS AND THUNDERSTORMS...BUT WERE
DESTABILIZING ACROSS NW MN. A COLD FRONT WAS MOVING ACROSS NW MN
AND THERE WERE SOME AGITATED CU ACROSS NW MN. ANOTHER AREA OF CU
WAS ACROSS WC MN. SPC JUST ISSUED A NEW MCD FOR AREAS TO THE WEST
AND SW OF THE CWA. THINGS SHOULD START TO BECOME MORE ORGANIZED IN
THAT AREA OVER THE NEXT FEW HOURS...AND MAY THEN MOVE INTO OUR
WESTERN AND SOUTHERN AREAS DURING THE EVENING.

AS IS TYPICAL WITH CONVECTION...THE MODELS ARE HAVING A TOUGH TIME
PINPOINTING SPECIFIC AREAS OF EXPECTED QPF. WILL BASICALLY FOLLOW
THE GREATEST POTENTIAL WITH THE FRONT AND ALSO IN THE VICINITY OF
THE FRONT ACROSS WESTERN AND CENTRAL MN. WILL GO WITH SCATTERED/
CHANCE POPS ACROSS THE BOARD THIS EVENING AND UPDATE TO HIGHER
POPS AS THINGS SHAPE UP. OVERNIGHT LOWS SHOULD DROP MOST IN THE NW
ZONES...AND LEAST IN NW WI. STILL A POTENTIAL FOR SEVERE
THUNDERSTORMS ACROSS THE NORTHLAND THIS EVENING BASED ON SPC
MESOSCALE ANALYSIS INFORMATION.

HIGH PRESSURE WILL BUILD IN ON SUNDAY...BRINGING AN END IN THE
PRECIPITATION FROM NW TO SE. COULD STILL SEE SOME LINGERING
SHOWERS AND STORMS IN THE FAR SOUTH OR IN NW WI. THE CHANCE OF
PRECIPITATION COMES BACK INTO THE PICTURE CWA WIDE LATER SUNDAY
NIGHT AND MONDAY...AS LOW PRESSURE EMERGES INTO THE NORTHERN
PLAINS. THE MODELS CONTINUE TO INDICATE THAT THERE COULD BE A
SUBSTANTIAL RAINFALL EVENT MONDAY NIGHT AND TUESDAY...WITH ALL
MAJOR MODELS HINTING AT POSSIBLE MCS ACTIVITY WITH HEAVY RAIN.
WILL CONTINUE WITH LIKELY POPS FOR THAT PERIOD.

.EXTENDED...TUESDAY NIGHT THROUGH SATURDAY. BROAD UPPER LEVEL
RIDGING OVER THE CENTRAL CONUS WILL KEEP THE UPPER PLAINS IN A
REGION OF UNSETTLED ZONAL FLOW. THERE WILL BE SEVERAL
OPPORTUNITIES FOR SHORT WAVES TO TRACK EAST OVER THE NORTHLAND AND
TRIGGER SHRA/TSTMS THROUGH THE EXTENDED. DUE TO UNCERTAINTY IN
TIMING OF ANY WAVES KEPT LONG TERM DRY ATTM WITH SEASONAL TEMPS.

&&

.AVIATION.../18Z TAF ISSUANCE/
VFR CONDITIONS TO CONTINUE THROUGH THE PERIOD. THUNDERSTORMS WILL
MOVE OUT OF THE KHYR SITE EARLY THIS AFTERNOON. ISOLATED
THUNDERSTORMS MAY DEVELOP ALONG A COLD FRONT LATER THIS AFTERNOON
AND CONTINUE INTO THE EVENING HOURS. PUT SOME LOWER VISBYS IN FOR
KBRD AND KHYR OVERNIGHT TO ACCOUNT FOR POSSIBLE PATCHY FOG.
