Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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, Jun 11, 4:10 PM CDT, 5 hours 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND 410 PM CDT SAT JUN 11 2005 .DISCUSSION...HEAVY RAIN IS SLOWLY DECREASING AND MOVING NORTH WITH THE AREA OF HEAVIEST RAIN CORRELATING BEST WITH GFS JET DIVERGENCE COUPLETS. EXTREME SOUTHEAST ND APPEARS FINALLY READY GET SOMETHING OF A MUCH NEEDED DRY SLOT THOUGH SCATTERED SHOWERS MAY RETURN INTO EVENING. SHOWERS/THUNDERSTORMS DEVELOPING NEAR AND EAST OF SD/MN LINE DON/T LOOK ESPECIALLY THREATENING ATTM BUT PROBABLY ONLY NEEDS A BIT MORE WARMING TO KICK OFF TO SEVERE. THE LOW PRESSURE CENTER IS CURRENTLY TRACKING ABOUT 50 NM FARTHER WEST OF MODELS LOCATION AND WILL PLACE AREAS EAST OF RED RIVER VALLEY INTO THE WARM SECTOR EARLY TONIGHT. .SHORT TERM...GFS MODEL STILL APPEARS TO HAVE THE BEST HANDLE AND ACCEPTED ITS QPF VALUES WITH SOME DOWNWARD ADJUSTMENT. LOTS OF RAIN NEXT SEVERAL DAYS IS CAUSE FOR CONCERN IN KEEPING SOILS SATURATED SO WILL ISSUE ESF. AN EXPECTED BREAK ON SUNDAY WILL PROVIDE MUCH HELP BUT MAYBE NOT ENOUGH TO KEEP SOME FLOODING. .LONG TERM (WED-SAT)... MAIN QUESTION IN THE EARLY PART OF THE EXTENDED IS HOW FAST WILL THE UPPER LOW PRESSURE SYSTEM MOVE OUT. CANADIAN/ECMWF ARE A BIT SLOWER THAN THE GFS...BUT WILL HOLD OFF FOR NOW (WITH CONSENSUS) ON ADDING ANY PCPN TO THE EARLY PART OF WED. THEREAFTER LOOKING AT A BUILDING 500MB RIDGE AND A DRY/WARM PERIOD. THIS HAS GOOD MODEL CONSISTENCY AS WELL. ONLY QUESTION IS HOW WARM TO GO. GFS SEEMS TO BE SLOW AT BUILDING THE WARMER AIR IN...BUT THAT IS A TENDENCY OF THAT MODEL. WOULD LIKE TO GO A BIT HIGHER THAN MEX GUIDANCE TEMPS (CLOSER TO HPC)...BUT WILL STAY IN THE LOW 80S FOR NOW. && .AVIATION... LOTS OF RAIN SPREADING INTO ALL THE TAF SITES...WHICH WILL MEAN A PROLONGED PERIOD OF LOWER CEILINGS/VSBYS. AS SYSTEM PULLS OUT LATE TONIGHT WILL HAVE TO WATCH FOR FOG POTENTIAL AGAIN. LOOKS LIKE MOST CLOUD COVER SHOULD ALSO EXIT THE AREA BY MID MORNING SUNDAY. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...ESF ISSUED FOR HEAVY RAIN. MN...ESF ISSUED FOR HEAVY RAIN. && GV
