Local storm reports filed while the alert was in force, from inside its polygon or its counties.
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.
The nearest sounding before it
International Fa, MN (KINL), launched 00:00Z, 9.9 hours before the alert went out and 276 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.

JDSWhat 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 Grand Forks, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at Sep 5, 4:00 AM CDT, 54 minutes earlier.
Area forecast discussion, Sep 5, 4:00 AM CDT, 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 400 AM CDT MON SEP 5 2005 .DISCUSSION AND SHORT TERM (TODAY-TONIGHT)...SERIES OF SHORTWAVES AND ASSOCIATED UPPER JET MAXIMA TO PARADE OVER THE AREA. THE FIRST IS STILL CAUSING A FEW SEVERE THUNDERSTORMS IN A BROKEN LINE OF STORMS FROM NORTHEAST SD TO SOUTHEAST MB. THE LARGEST CLUSTER IN ROSEAU/MARSHALL COUNTIES MN IS ON THE CONVERGENT LEFT QUADRANT OF THE LOW LEVEL JET WHICH THE RUC SLOWLY SHIFTS THROUGH LAKE OF THE WOODS BY AROUND SUNRISE. EXPECT THIS LINE TO GRADUALLY WEAKEN AND MOVE EAST. ANOTHER SHORTWAVE NEAR EASTERN MT BORDER WILL SKIRT BY PROBABLY WITH NO MORE THAN ISOLATED THUNDER AND MAYBE NONE THIS MORNING. THE SHORTWAVE TO WATCH HAS JUST PASSED YELLOWSTONE PARK AND IS RATHER OBSCURE IN WATER VAPOR. BUT THIS IS THE ONE NAM AND GFS SHOW WITH A LOT OF UPPER JET DIVERGENCE WITH THE MODELS PLACEMENT DETERMINING WHERE THE MOST QPF OCCURS...FARTHER SOUTH IN NAM. UKMET SHOWS THIS SHORTWAVE BECOMING ABSORBED INTO THE MORE DOMINANT JET LATE TODAY APPROACHING OVER SOUTHERN SASK...WHICH SEEMS AN UNLIKELY SCENARIO. LOW LEVEL CONVERGENT FLOW NEAR THE BAROCLINIC BOUNDARY NEAR THE TROUGH AND COOL FRONT TO PROVIDE MOST OF THE REMAINING LIFT FOR POSSIBLE SEVERE STORMS AGAIN THIS AFTERNOON AND EVENING. CONVECTIVE TEMPERATURES WILL NEVER BE REACHED BUT THERE WILL BE ENOUGH ASSISTED LIFT FROM THE FRONT AND JET DYNAMICS THAT LACK OF SURFACE HEATING LIKELY WILL NOT DETER DEVELOPMENT. MAY NEED TO CONSIDER A FLASH FLOOD WATCH IF THUNDERSTORMS CONTINUE THIS MORNING AND GREATER RAINFALL WILL OCCUR THAN WHAT IS IN OUR GRIDS BUT FLASH FLOOD GUIDANCE REMAINS RELATIVELY HIGH. SOME AREAS IN UPPER RED RIVER REACH HAVE RECEIVED 2+ INCHES TONIGHT ACCORDING TO RADAR STORM TOTAL PRECIP AND DOESN/T QUITE APPEAR DONE. ALSO IT SEEMS THAT IF NAM IS CORRECT THEN HEAVY RAIN WILL FOCUS SOUTHWARD ALONG THE EASTWARD MOVING FRONT AND TRAINING STORMS WILL NOT BE A PROBLEM. IF GFS IS MORE CORRECT THEN HEAVY RAIN WOULD OCCUR (NORTHERN COUNTIES) WHERE LESS RAIN HAS FALLEN. WILL HOLD OFF ON THIS FOR NOW. .EXTENDED...MADE NO CHANGES THIS MORNING THOUGH CONSIDERED ADDING CHANCE OF THUNDER TO NEXT MONDAY. DAY SHIFT MAY EVALUATE THIS FURTHER. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...NONE. MN...NONE. && GV

A COLD FRONT SWEEPING SOUTHEAST ACROSS THE REGION THIS AFTERNOON AND TONIGHT WILL INTERACT WITH VERY MOIST AND UNSTABLE AIR POOLING AHEAD OF THE FRONT. THIS SCENARIO WILL SET THE STAGES FOR EXPLOSIVE STORM DEVELOPMENT THIS EVENING AND TONIGHT. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY THUNDERSTORM ACTIVITY WITH THE POTENTIAL FOR ADDITIONAL SEVERE STORMS WILL PERSIST MONDAY INTO MONDAY NIGHT ACROSS THE REGION. IN ADDITION...HEAVY RAINFALL WILL BE POSSIBLE WHICH MAY LEAD TO ISOLATED AREAS OF FLASH FLOODING.
