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
Aberdeen, SD (KABR), launched 00:00Z, 2.3 hours before the alert went out and 59 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.

What 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 Sioux Falls, SD wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 14, 8:55 PM CDT, 25 minutes earlier.
Area forecast discussion, Aug 14, 8:55 PM CDT, 25 minutes before
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 855 PM CDT THU AUG 14 2008 .DISCUSSION... NMRS SHRA AND TS CONT TO FIRE IN OUR WRN FA. THIS ACTIVITY HAS BEEN CLOSELY TIED WITH A MESOSCALE SFC LOW...AM AN NOT LOOKING FOR IT TO MOV A LOT FURTHER EWD FROM THE JAMES RIVER VALLEY. CALLING AROUND YIELDED A FAIR AMOUNT OF SPOTTY HEAVY RAIN REPORTS...BUT HAIL AND WIND HAVE BEEN LIMITED. CURRENTLY AS THE SUN SETS...WE ARE LOSING OUR CORES ALOFT AND THUS OUR SVR POTENTIAL WITH IT. THE TS TO OUR EAST OVR SWRN MN HAS RAPIDLY DIED WITH THE DAYTIME HEATING. THOSE CELLS GOT GOING LATE THIS AFTN FM WEST CENTRAL MN AROUND THE PERIPHERY OF THE SFC HIGH...BUT LITTLE IN THE WAY OF DYNAMICS AND CONVERGENCE EXISTS TO MAINTAIN THOSE. STILL FEEL THAT OUR WX/POP GRIDS LOOK PRETTY GOOD AFT MIDNIGHT...BUT DID ADJUST OUR EVENING WX/POP GRIDS A BIT. WL DOUBLE CHECK THE 9 PM OBS BEFORE LAUNCHING A ZFP UPDATE. && .AVIATION... SCATTERED THUNDERSTORMS VICINITY OF KHON WILL PRODUCE LOCAL MVFR CIGS AND VSBYS THROUGH ABOUT 05Z...OTHERWISE VFR ACROSS THE FORECAST AREA THROUGH THE PERIOD. && .PREV DISCUSSION... UPPER LEVEL LOW ACROSS EASTERN MONTANA THURSDAY AFTERNOON IS EXPECTED TO DIVE TO THE SOUTH AND WEST OVERNIGHT. BEST CHANCES FOR LATE AFTERNOON AND EVENING THUNDERSTORMS APPEARS TO BE WEST OF I-29. AS THE EVENING WEARS ON...EXPECT THUNDERSTORMS TO DECREASE IN AREAL COVERAGE...THOUGH A FEW LIGHT SHOWERS COULD CONTINUE WEST OF THE JAMES RIVER VALLEY OVERNIGHT DUE TO WARM AIR ADVECTION ALOFT. INSTABILITY THIS EVENING APPEARS TO BE SOMEWHAT LIMITED...SO ANY SEVERE THREAT WOULD BE VERY ISOLATED IN NATURE. FLOW SHOULD BE RELATIVELY WEAK...BUT PREDOMINANT NORTHEAST WINDS SHOULD DRAW DRIER AIR INTO THE REGION. HAVE SIDED WITH LOWS IN THE MID AND UPPER 50S ACROSS SOUTHWEST MINNESOTA/NORTHWEST IOWA...WHILE AREA FURTHER TO THE WEST REMAIN IN THE LOWER 60S DUE TO CLOUD COVER. FOR FRIDAY...MODELS STILL TRENDING UPPER LEVEL SUPPORT FARTHER SOUTH WITH DRY AIR INTRUDING FROM THE EAST AND NORTHEAST. WITHOUT MUCH INSTABILITY...THE LOSS OF MOISTURE WILL TAKE THE CHANCE FOR RAINFALL FARTHER SOUTH. SO WENT AHEAD AND INCLUDED LOW POPS FOR JUST THE SOUTHWESTERN QUARTER OF THE CWA AND BY FRIDAY NIGHT JUST GOING WITH AN ISOLATED POTENTIAL OVER THE FAR SOUTH. HIGHS ON FRIDAY WILL BE VERY NICE...RANGING FROM THE MID 70S TO LOWER 80S. WITH THE DRY AIR AND WEAK FLOW IN FRIDAY NIGHT MOST LOCATIONS WILL FALL INTO THE 50S. THE WEEKEND LOOKS LIKE IT SHOULD STAY DRY AS COOL AND STABLE AIR REMAINS IN PLACE AND ANY UPPER LEVEL SUPPORT REMAINS TO THE SOUTHWEST OF THE AREA. THE MODELS ARE HINTING AT A FEW WEAK IMPULSES DROPPING THROUGH MAINLY SW MN SATURDAY SO AN ISOLATED SHOWER NOT COMPLETELY OUT OF THE QUESTION...BUT COVERAGE SHOULD BE LOW. TEMPERATURES WILL MODERATE CLOSER TO NORMAL WITH LOWS MAINLY IN THE 50S TO LOW 60S AND HIGHS FROM THE UPPER 70S TO UPPER 80S. IN THE LATTER PERIODS(MON-THU)...MAIN CHALLENGE WILL BE FIGURING OUT JUST WHERE THE UPPER LOW WILL END UP. THE 0Z AND 6Z GFS AS WELL AS THE 0Z ECMWF AND 0Z GFS ENSEMBLE ALL IN PRETTY GOOD AGREEMENT TODAY ON TAKING UPPER LOW INTO KS ON MONDAY...THEN FASTER FLOW DEVELOPS ACROSS THE NORTHWEST U.S. AND SHOULD AID IN LIFTING THIS LOW TO THE NORTH TUESDAY INTO WEDNESDAY. THESE TWO DAYS SHOULD PROVE TO BE OUR BETTER CHANCES FOR RAIN AND THUNDERSTORMS...BUT THE CHANCES COULD CONTINUE THROUGH THE END OF THE WEEK AS POTENTIALLY MUCH MORE UNSTABLE AIR SETS UP THURSDAY AND A RELATIVELY STRONG WAVE MOVES INTO THE NORTHERN PLAINS THURSDAY NIGHT INTO FRIDAY. TOO FAR OUT TO GET EXCITED ABOUT BUT COULD END UP WITH A DECENT PATTERN FOR SEVERE WEATHER LATE IN THE WEEK. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE.
