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 12:00Z, 11.9 hours before the alert went out and 286 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, Jun 24, 1:28 PM CDT, 5 hours 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 128 PM CDT SAT JUN 24 2006 .SHORT TERM... SEVERAL SHORTWAVES CONTINUE TO ROTATE TOWARDS REGION...ALONG WITH MODEST INSTABILITY WILL LEAD TO SOME THUNDERSTORMS THIS AFTERNOON AND TONIGHT. MODELS AGAIN IN GOOD AGREEMENT...AND LIKE NAM DEPICTION OF QPF/MOISTURE FIELDS SO WILL FOLLOW. FOR TONIGHT...EXPECT THUNDERSTORMS TO BE SCATTERED AROUND THE REGION. STORM MODE WILL BE DOMINATED BY PULSE MULTICELLS...WITH AROUND 10KT OF 0-6KM SHEAR ALONG WITH VERY LITTLE OVERALL HODOGRAPH LENGTH (IE. TOTAL SHEAR). THERE WILL BE STEEP LAPSE RATES THOUGH AS 500MB COLD POOL COMES OVER THE AREA THIS EVENING. THERE COULD BE A FEW PULSE SEVERE HAIL REPORTS AND/OR A WIND GUST TO NEAR SEVERE LIMITS...BUT GUSTS TO AROUND 40MPH SHOULD BE THE RULE WITH LITTLE WIND ALOFT TO TRANSPORT TO SFC...AND FAIRLY MOIST PROFILES IN MID LEVELS. I AM NOT EXPECTING TOO MUCH ORGANIZED SEVERE WITH VERY LIMITED SHEAR PROFILES AND SFC CONVERGENCE...ALTHOUGH SPC HAS INCLUDED SOME OF THE AREA IN THE DAY1 SLIGHT RISK. RADAR TRENDS OVER THE LAST HOURS INDICATE NO VERTICAL TILT TO SMALL MULTICELL CORES WHICH LINES UP WELL WITH 10KT OF 0-6KM SHEAR. FURTHER SOUTH...0-6KM SHEAR IS AROUND 25-30KT IN MPX FORECAST AREA...AND BOW ECHO HAS DEVELOPED IN THIS ENVIRONMENT WHERE A SEVERE THUNDERSTORM WATCH IS IN EFFECT.. FOR SUNDAY...EXPECT A DRY DAY WITH SLIGHTLY WARMER TEMPS ALOFT AND SFC HIGH PRESSURE. HIGHS WILL WARM TO NEAR NORMAL FOR THIS TIME OF YEAR. ON MONDAY...A COOL FRONT WILL PASS THROUGH THE REGION MONDAY AFTERNOON...ALONG WITH SOME INSTABILITY. THEREFORE WILL NEED TO CONTINUE CHANCE FOR THUNDER. BY TUESDAY...CYCLONIC FLOW AND COLD AIR ALOFT WILL ONCE AGAIN PROVIDE ENOUGH INSTABILITY FOR SOME THUNDER. THE BEST CHANCES FOR THUNDER BOTH MONDAY AND TUESDAY WILL BE IN THE AFTERNOON. TEMPS WILL BE NEAR NORMAL ON MONDAY AND COOL SLIGHTLY BELOW NORMAL FOR TUESDAY WITH COLDER AIR ALOFT...CYCLONIC FLOW AND UPPER LOW EAST OF THE FORECAST AREA. .LONG TERM (WED-SAT)... MAIN ISSUES REVOLVE AROUND 500MB TROUGH PROGGED TO BE OVER WRN/CNTRL GREAT LAKES REGION MIDWEEK AND WHAT...IF ANY...EFFECT WILL HAVE ON WEATHER OVER ERN ND/NW MN. NCEP MEANS AS AS WELL AS 06Z GFS/12Z CANADIAN/00Z ECMWF ALL HANDLE UPPER TROUGH RATHER SIMILAR INITIALLY WITH UPPER LOW CENTER OVER ERN MN/NW WI WEDNESDAY...THEN SOME DIFFERENCES EMERGE ON HOW FAST TROUGH WILL MOVE EAST AND OUR FLOW GOES ZONAL. 12Z CANADIAN IS MORE WITH THE TROUGH HANGING OVER THE GREAT LAKES LIKE 06Z-12Z GFS. ATTM WILL THINK ITS INFLUENCE WILL BE WITH COLDER AIR ALOFT WHICH COMBINED WITH SFC HEATING WILL GENERATE SCT TSTMS WED AFTN OVER NW/WCNTRL MN. DEPENDING ON TROUGH MOVEMENT THIS PATTERN MAY BE REPEATED FOR OTHER DAYS...BUT FOR NOW WILL LEAVE THU-FRI DRY. HPC PROGS SHOW HIGH DROPPING OVER CNTRL ND IN THAT TIME FRAME. AIRMASS IS MODERATELY COOLER WITH TEMPS AVERAGING JUST A FEW DEGREES BLO NORMAL. && .AVIATION... ISOLATED-SCATTERED CONVECTION TO PLAY HAVOC WITH TAF SITES THE REST OF SAT AFTN/EARLY EVENING. OTHERWISE VFR CONDITIONS TO RULE WITH MID LEVEL CU DEVELOPING AROUND 5000 TO 6000 FT WITH THIN CIRRUS CANOPY ABOVE THAT. BRIEF GUSTY WINDS TO 30KTS PSBL NEAR ANY STORM ALONG WITH LOCAL LOW LEVEL WIND SHEAR DUE TO QUICK CHANGES IN WIND DIRECTION IN SPEED. OUTSIDE OF STORMS WINDS WILL REMAIN LIGHT AND MAINLY NORTH OR NORTHWEST. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...NONE. MN...NONE. && DK/RIDDLE
