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.
The nearest sounding before it
International Fa, MN (KINL), launched 12:00Z, 11.0 hours before the alert went out and 147 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jul 22, 1:29 PM CDT, 4 hours 29 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 129 PM CDT THU JUL 22 2010 .SHORT TERM... THE MAIN CHALLENGE FOR THIS FORECAST WILL BE SEVERE/HEAVY RAIN POTENTIAL THIS AFTERNOON AND EVENING...AND ANOTHER WAVE FOR FRI NIGHT INTO EARLY SAT. MODELS ARE IN GOOD AGREEMENT OVERALL...AND PREFER THE NAM FRONTAL PLACEMENT AND MOISTURE/INSTABILITY FIELDS. FOR THE REST OF THIS AFTERNOON AND EVENING...A STRONG SHORTWAVE FOR LATE JULY WILL MOVE INTO EASTERN ND THIS AFTERNOON. THIS WILL COMBINE WITH AMPLE MOISTURE PER DEWPOINTS WELL INTO THE MID/UPPER 60S AND PWATS APPROACHING 1.75 IN THE NORTH. THERE WILL ALSO BE STRONG DEEP LAYERED SHEAR AROUND 50KT IN THE 0-6KM LAYER...IN ADDITION TO MLCAPES AROUND 1000 J/KG WHERE ANY INSOLATION CAN BREAK THROUGH CLOUD CANOPY. LASTLY...A SFC LOW IS PROGGED TO DEVELOP NEAR GRAND FORKS BY 00Z...WITH A WELL DEFINED TROUGH RUNNING FROM NORTH TO SOUTH. GIVEN THIS SET UP...WILL MENTION SEVERE WORDING AND HEAVY RAIN ALONG AND WEST OF THE VALLEY FROM 21Z-00Z. WILL ALSO MENTION HEAVY RAIN IN NW MN FROM 00-03Z...WITH SOME AREAS SEEING AN INCH OR MORE IN A SHORT TIME. CONVECTION SHOULD MOVE OUT OF THE AREA QUICKLY AFTER 06Z AS THE SHORTWAVE PASSES THROUGH. FOR FRI/FRI NIGHT...ANOTHER SHORTWAVE WILL TARGET MAINLY THE SOUTHERN 1/3 OF THE FORECAST AREA. INSTABILITY WILL BE GREATEST IN THE FAR SOUTH...WITH PWATS ONCE AGAIN OVER 1 INCH. THEREFORE...WILL INCREASE POPS BY FRI NIGHT. ON SAT/SUN...ANY LINGERING CONVECTION SAT MORNING SHOULD MOVE OUT OF ALL AREAS BY SAT AFTERNOON. THEREAFTER EXPECT A SLOW WARMING TREND SLIGHTLY ABOVE NORMAL BY SUNDAY WITH A SHORTWAVE RIDGE BUILDING INTO THE AREA. .LONG TERM [SUN NIGHT - WED]... THE MODELS ARE IN DECENT AGREEMENT. SUNDAY NIGHT LOOKS DRY...BUT THE MODELS INDICATE A COLD FRONT WILL TRANSITION FROM SOUTH CENTRAL CANADA TO THE NORTHERN PLAINS EARLY NEXT WORK WEEK...PROVIDING A CHANCE OF SHOWERS AND THUNDERSTORMS. THE FRONT COULD STALL THROUGH WEDNESDAY...SO CHANCES OF PCPN REMAIN THROUGH THE FORECAST PERIOD. TEMPERATURES SHOULD BE NEAR OR SLIGHTLY ABOVE NORMAL. && .AVIATION... IFR/MVFR CIGS AND VFR/MVFR VSBYS ARE LIKELY TO CONTINUE THROUGH AT LEAST THIS EVENING FROM SHOWERS AND THUNDERSTORMS AS A COLD FRONT PUSHES THROUGH THE NORTHERN PLAINS. THE BEST CHANCE FOR THUNDERSTORMS IS IN THE VALLEY...SO GFK AND FAR WERE GIVEN A TEMPO OF -TSRA FOR THE LATE AFTERNOON. THE BULK OF PCPN SHOULD MOSTLY BE RAIN SHOWERS AT DVL/TVF/BJI...BUT CANNOT RULE OUT SOME LIGHTNING. THE SOUTHERLY AND SOUTHEASTERLY WINDS ACROSS AND EAST OF THE VALLEY WILL SHIFT TO THE NORTHWEST THIS EVENING ONCE THE COLD FRONT PASSES THROUGH EACH SITE. && .FGF WATCHES/WARNINGS/ADVISORIES...
