What happened
The episode as NWS FGF wrote it up.
A stationary boundary set up in the early morning hours of the 25th from Dickinson (ND) to Devils Lake (ND) to Hallock (MN). This boundary held in place for the next three hours, then finally sagged toward a Baudette (MN) to Grand Forks (ND) line around sunrise. Thunderstorms initially developed across southern Manitoba and northwest North Dakota, which brushed the international border area north of Devils Lake. Around sunrise, a better developed line of thunderstorms formed in northeast North Dakota and moved into northwest Minnesota, where they quickly weakened.

Area forecast discussion, Jun 25, 2:09 AM CST, 4 hours 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 309 AM CDT MON JUN 25 2007 .SHORT TERM (TODAY-TONIGHT)...SEVERE THUNDERSTORMS CONTINUE ALONG CANADIAN BORDER AND WELL NORTH OF THE LOW LEVEL JET WHICH IS ON SOUTH SIDE OF THE FRONTAL BOUNDARY. FRONT CURRENTLY IS NORTH OF A BIS/GFK/HCO/BDE LINE AND EXPECT IT TO CHANGE LITTLE TODAY UNDER PARALLEL UPPER FLOW. SURFACE LOW CURRENTLY NORTH OF THE BLACK HILLS WILL WEAKEN AND ELONGATE NORTHEAST ALONG THE FRONT/TROUGH. LARGE SCALE ASCENT NORTH OF THE FRONT IS HELPING MAINTAIN THE THUNDERSTORMS BUT EXPECT SLOW WEAKENING AS THE AIR LIFTED OVER THE FRONT CONTINUES TO BE COOLER THAN WHAT IT STARTED WITH. STRONG CAPPING ISSUE STILL LURKS TODAY AS 700 MB TEMPERATURES CLIMB TO +13C TO +14C ACROSS ALMOST THE ENTIRE CWA (16 TO 16.5 KFT FREEZING LEVEL). INITIATION OF SURFACE BASED STORMS MAY BE VERY DIFFICULT AND AM NOT SURE IT CAN. BUT THE MOST LIKELY AREA WILL BE JUST NORTH OF THE FRONT OVER THE DVL BASIN AND TOWARDS ROX AGAIN...AND DO NOT EXPECT SEVERE STORMS BEFORE EVENING. ELEVATED STORMS TONIGHT WILL HAVE A TOUGH TIME TOO SINCE THE NOSE OF THE LOW LEVEL JET IS EXPECTED TO BE NEAR THE SOUTHEAST ND CORNER AT 06Z...DEEP UNDERNEATH THE STRONGEST PART OF THE CAP. MEANWHILE THE JET VEERS TOWARD WEST CENTRAL MN AFTER 06Z...NOT USUALLY FAVORABLE FOR SEVERE STORMS. .LONGER TERM (TUE-SUN)...VERY FEW CHANGES MADE HERE AS MODELS ARE VERY CONSISTENT. EXPECT A QUIET WEEK AFTER TONIGHT...COOLER AND DRIER AS NORTHWEST FLOW PUSHES DEEP MOISTURE WELL TO THE SOUTH. && .AVIATION...A FEW AREAS OF LOW CLOUDS AND FOG MIGHT BRUSH THROUGH WEST CENTRAL MN THIS MORNING BUT BELIEVE THEY WILL STEER CLEAR OF THE TAF SITES. VFR CONDITIONS WILL CONTINUE TODAY EXCEPT WHERE THUNDERSTORMS MIGHT PERSIST FOR SEVERAL HOURS AT A TIME...MOST LIKELY NORTHEAST ND THIS EVENING. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...NONE. MN...NONE. && GV
