Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS FGF wrote it up.
A stationary front had been located along a Roseau (Minnesota) to Grand Forks (North Dakota) line around midday. This boundary essentially washed out by late afternoon. However, showers and thunderstorms continued along the boundary for most of the day, and one stronger cell formed by late afternoon. This thunderstorm cell produced the tornado and funnel cloud reports.
The local office's own words before the first event, 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 the first event at Jun 14, 1:30 PM CST, 2 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 230 PM CDT THU JUN 14 2007 FORECAST CHALLENGE CONTINUES TO BE TEMPERATURES AND RAIN CHANCES THROUGH PERIOD. MODELS INITIALLY IN REASONABLE AGREEMENT BUT SOME LOW LEVEL DIFFERENCES WITH SURFACE BOUNDARIES SUNDAY BETWEEN NAM/GFS. WILL LEAN WITH GFS FOR DETAILS AND STAY CONSISTENT IN LATER PERIODS WITH MODEL DIFFERENCES. COMPACT MID LEVEL CIRCULATION OVER EAST CENTRAL ND CONTINUES TO AID IN MAINTAINING MODERATE RAINFALL ALONG NORTHERN END OF NEARLY STATIONARY BOUNDARY FROM EXTREME SE ND TO NEAR LAKE OF THE WOODS. HEAVIER RAIN BAND SHOULD LIFT NORTHWARD ACROSS INTERNATIONAL BORDER WITHIN NEXT HOUR OR SO. TO THE SOUTH OF THIS FEATURE PCPN MORE SPOTTY BUT NOT ABSENT AS ANOTHER CURCULATION CONTINUES OVER EASTERN SD PROVIDING LOW LEVEL CONVERGENCE. MAIN SHORTWAVE OVER N CENTRAL MT TO LIFT NE TONIGHT INTO EARLY FRIDAY WITH MOST OF THE UPPER SUPPORT LIFTING NORTH OF BORDER. ASSOCIATED COOL FRONT WILL APPROACH THE NW FA THIS EVENING CROSSING MAINLY THE NW HALF OF FA BY MORNING. COMBINATION OF ALL THE ABOVE INHIBIT PULLING POPS FROM ANY PART OF FA TONIGHT. APPEAR THE BEST POTENTIAL FOR STRONGEST STORMS WILL BE OVER DVL BASIN WITH APPROACHING BOUNDARY AND REACHING CONVECTIVE TEMPERATURES IN CLEAR SLOT. STRONGEST 0-6KM SHEAR DOES NOT REACH THIS AREA TIL LATER THIS EVENING AND WITH OVERALL LACK OF LOW LEVEL JET FEEL ANY STRONGER CONVECTION WILL BE SPOTTY. FATHER EAST COLUMN MORE TROPICAL AND ANY BREAKS IN CLOUDS WILL AID WITH CONVECTIVE POTENTIAL AS AIRM MASS IS MODERATELY UNSTABLE. WITH VERY HIGH FREEZING LEVELS ANY CONVECTIVE ISSUES OTHER THAN LOCALIZED HEAVIER RAINFALL COULD BE SOME WIND. AT THIS POINT SEVERE POTENTIAL DOES NOT SEEM WIDESPREAD ENOUGH TO MENTION IN BODY OF FORECAST AT THIS POINT BUT WILL MENTION TSRA ACROSS ENTIRE REGION. SOME LOW LEVEL DRYING IN WAKE OF BOUNDARY PASSAGE WITH SUB 60 DEWPOINTS CONFINED TO WESTERN FA. REMAINDER OF FA WILL SEE ANOTHER MILD NIGHT. WITH PASSAGE OF SHORT WAVE MID LEVEL FLOW BECOMES MORE ZONAL WHICH SHOULD HELP PUSH BOUNDARY EAST EXCEPT UNFORTUNATELY ACROSS FAR SOUTHERN FA WHERE BOUNDARY BECOMES EAST-WEST ORIENTED AND PARALLEL TO FLOW. JUST WHERE BOUNDARY SETS UP WILL DETERMINE FAVORED RAIN AREA BUT WILL NEED TO MAINTAIN SOME POP MENTION. REMAINDER OF FA SHOULD BE FOR THE MOST PART RAIN-FREE AND WITH SOME SOLAR TEMPERATURES SHOULD BE SEASONAL. BOUNDARY HANGS ACROSS SD SATURDAY WITH MINOR SHORT WAVE TRACKING THROUGH ZONAL FLOW. WITH LITTLE NORTHWARD PUSH OF BOUNDARY WILL MAINTAIN POPS ACROSS SOUTH. WITH WARM ADVECTION CLOUDS WILL DETERMINE OVERALL TEMP RECOVER BUT STILL LOOKING ATLEAST AVERAGE. NEXT SHORTWAVE OF INTEREST SHIFTS INTO NORTHERN ROCKIES SATURDAY NIGHT ORGANIZING SURFACE LOW PRESSURE/CONVERGENCE OVER NORTHERN HIGH PLAINS. INCREASING SOUTHERLY FLOW WILL BEGIN TO LIFT E-W ORIENTED WARM FRONT NORTHWARD TO ND/SD BORDER. LOW LEVEL JET MORE ROBUST WHICH COULD SUSTAIN CONVECTION PROPAGATING INTO SOUTHERN AND WESTERN PORTIONS OF FA. MOST ACTIVE DAY WILL BE SUNDAY AS WAVE AND ASSOCIATED LOW LEVEL BOUNDARIES SHIFT INTO FA. ACTUAL BOUNDARY LOCATIONS WILL DETERMINE HEAVIEST RAIN/SEVERE POTENTIAL. WITH MODEL DIFFERENCES WILL HOLD CURRENT POPS AS IS. .LONG TERM (MON-THU)...ECMWF AND GFS 180 DEGREES DIFFERENT. ECMWF SHOWING UPPER LEVEL TROUGH APPROACHING AND MOVING THROUGH THE FA WITH GFS SHOWING UPPER LEVEL RIDGE ACROSS THE FA. ECMWF ACTUALLY BREAKS IT OWN CONTINUITY...BUT UKMET/GEM/NOGAPS AGREE WITH ECMWF. NEEDLESS TO SAY CONFIDENCE NOT TOO GREAT. HPC PREFERS ECMWF BECAUSE OF PAST PERFORMANCE AND CONSENSUS WITH OTHER GUIDANCE. THIS WOULD MEAN A WETTER/COOLER SOLUTION THAN CURRENT FORECAST. WILL NOT MAKE SIGNIFICANT CHANGES TO THE FORECAST AT THIS POINT...BUT WILL INSERT SLIGHT THUNDER CHANCES ON TUE AND AS WELL AS ACROSS THE EXTREME S FA WED-THU (AS PER HPC GUIDANCE). TEMPERATURES SHOULD BE NEAR NORMAL. && .AVIATION...VFR CONDITIONS EXPECTED TO PREVAIL BY MORNING ACROSS ALL TAF SITES. THE BIGGEST QUESTION IS WHEN WILL MVFR/IFR CEILINGS BECOME VFR FOR GOOD. THINKING CEILINGS WILL GRADUALLY LIFT THROUGH THE REMAINDER OF THE AFTERNOON/EVENING...WITH MVFR/IFR CEILINGS ASSOCIATED WITH A HEAVIER RAIN SHOWER DURING THIS TIME PERIOD. && .FGF WATCHES/WARNINGS/ADVISORIES...
