The radar
The Minneapolis radar (KMPX), 54 km from the middle of the area, began a volume at 20:27 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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
Minneapolis, MN (KMPX), launched 12:00Z, 8.4 hours before the alert went out and 51 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.

JLTWhat 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 Twin Cities, MN wrote its last area forecast discussion before this severe thunderstorm warning went out at Sep 17, 3:19 PM CDT, 7 minutes earlier.
Area forecast discussion, Sep 17, 3:19 PM CDT, 7 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 319 PM CDT THU SEP 17 2015 .SHORT TERM...(THIS EVENING THROUGH FRIDAY) ISSUED AT 319 PM CDT THU SEP 17 2015 SEVERE WEATHER LOOKS LESS PROBABLE FOR THE MAJORITY OF THE FORECAST AREA THIS AFTERNOON...DESPITE THE COLD FRONT STILL STRETCHED ACROSS WEST CENTRAL MN. ABUNDANT CLOUD COVER AND ONGOING CONVECTION HAS MINIMIZED THE AMOUNT OF DESTABILIZATION. CANNOT TOTALLY RULE OUT A FEW ROGUE SEVERE CELLS THAT DEVELOP INVOF THE FRONT WHERE TEMPORARY SCATTERING IN THE CLOUDS OCCURS...BUT THE BETTER FORCING ALOFT WILL BE DISPLACED TO THE EAST. WILL HOWEVER NEED TO CLOSELY MONITOR THE POTENTIAL FOR MORE HYDRO ISSUES...PRIMARILY FROM THE TWIN CITIES INTO NORTHWEST/WEST CENTRAL WI...GIVEN A SWATH OF 12-18 HOUR RAINFALL AMOUNTS IN THE 3 TO 6 INCH RANGE THERE...AND THE SLOW-MOVING NATURE OF STORMS THAT DEVELOP. BY 03Z...THE BULK OF THE RAINFALL SHOULD BE EAST OF THE AREA...WITH THE COLD FRONT FOLLOWING NOT TOO FAR BEHIND. CLOUDS SHOULD SCATTER OUT...BUT NORTHWEST WIND FLOW SHOULD BE SUFFICIENT TO INHIBIT FOG DEVELOPMENT OVERNIGHT. LOWS WILL DIP INTO THE UPPER 40S...WITH 50S EXPECTED ELSEWHERE. WILL NOT BE QUITE OUT OF THE WOODS ON FRIDAY AS FAR AS PRECIPITATION IS CONCERNED...GIVEN THE MAIN SHORTWAVE TROUGH OVER THE NORTHWEST WILL MAKE ITS WAY ACROSS THE AREA. MUCH LESS INSTABILITY AND LLVL MOISTURE TO WORK WITH AS THIS WAVE PASSES...WHICH WILL LIKELY MEAN A LACK OF THUNDER WITH THE SHOWERS AND PRECIP AMOUNTS UNDER A COUPLE TENTHS OF AN INCH OR LESS. THEREFORE THE THREAT FOR ADDITIONAL HYDRO ISSUES APPEARS LOW. TEMPERATURES WILL LIKELY NOT ESCAPE THE 60S GIVEN THE CLOUD COVER AND INFILTRATION OF COOLER AIR IN THE WAKE OF THE COLD FRONT. .LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY) ISSUED AT 319 PM CDT THU SEP 17 2015 FOR FRIDAY NIGHT...THE MAIN CHANGE IN THE FORECAST WAS TO SPEED UP THE PROGRESSION OF THE PRECIPITATION THROUGH OUR AREA...MORE QUICKLY DEPARTING TO THE EAST. BY THE EVENING...THE FORCING ASSOCIATED WITH THE SHORTWAVE WILL BE MAINLY ACROSS EASTERN MN AND WESTERN WI. THE UPPER LEVEL DIVERGENCE...PV BOOT AND F-GEN WILL BE FOCUSED OVER WESTERN WISCONSIN AND LIKELY PUSHING EAST OF EAU CLAIRE BY THE OVERNIGHT HOURS. SOME LINGERING PRECIP ON THE BACK SIDE IN WEAK LIFT WILL BE POSSIBLE...BUT DO NOT EXPECT MUCH IN TERMS OF QPF FRIDAY NIGHT. WENT AHEAD AND DRIED OUT THE FORECAST BY SATURDAY MORNING. AS FAR AS THE PLACEMENT OF THE PRECIP DURING FRIDAY NIGHT...IT THE AREA REMAINS CONSISTENT AS FAR SOUTHERN MN THROUGH WEST CENTRAL WI WILL SEE THE BEST CHANCE OF RAIN. FOR SATURDAY AND SUNDAY...THE COOLER 850MB TEMPS WILL BE WITH US THROUGH THE WEEKEND...AS A SURFACE HIGH AND SUBTLE RIDGE MOVES THROUGH. EXPECT MAINLY PARTLY CLOUDY SKIES THIS WEEKEND WITH HIGH TEMPERATURES ABOUT NORMAL THIS TIME OF YEAR...RIGHT AROUND 70 DEGREES. NEXT WEEK...A STRONG SYSTEM WILL DEVELOP ACROSS SASKATCHEWAN/MANITOBA. A STRONG JET STREAK WILL ACCOMPANY THIS SYSTEM IN CANADA...ALLOWING AN UPPER RIDGE TO PUSH INTO THE UPPER MIDWEST. LOW LEVEL FLOW WILL TURN SOUTHWESTERLY AND 850MB TEMPS WILL SURGE TO 15C-20C ACROSS THE AREA THROUGH THE MIDDLE OF NEXT WEEK. HIGH TEMPERATURES AROUND 75-80 DEGREES ARE EXPECTED WITH THE WARM SURGE. TUESDAY NIGHT MAY BRING SCATTERED SHOWERS AND THUNDERSTORMS UNDER THE WARM AIR ADVECTION REGIME...AND TAP INTO LIMITED INSTABILITY. SEVERE WEATHER DOES NOT APPEAR LIKELY. TOWARD THE END OF NEXT WEEK...A SHORTWAVE LOOKS TO RIDE THE RIDGE NORTHEAST AND BRING SHOWERS AND THUNDERSTORMS TO THE AREA...BUT THE WEEK WILL OTHERWISE BE MAINLY DRY. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON) ISSUED AT 103 PM CDT THU SEP 17 2015 FRONT PASSING ACROSS THE AREA WILL RENEW THUNDERSTORM ACTIVITY THIS AFTERNOON...AND AFFECT KMSP/KNRH/KEAU BY PRODUCING MVFR CIGS AND MVFR/IFR VSBYS. MAY ALSO SEE SOME SCT-BKN IFR LEVEL CIGS AT WESTERN SITES /KAXN/KRWF/KSTC/ BEHIND THE FRONT. MODELS PUSH THE CONVECTION OUT OF THE AREA BY 02Z FRIDAY...WITH TEMPORARY SCATTERING OUT OF THE CLOUD DECK. THE NEXT ROUND OF SHOWERS WILL APPROACH KRWF ON FRIDAY MORNING. TEMPORAL/SPATIAL CONFIDENCE IS LOW HOWEVER...SO HAVE NOT INCLUDED A MENTION AT THIS POINT. WINDS SHIFT TO THE NORTHWEST BEHIND THE FRONT. KMSP... WINDOW FOR THUNDERSTORM ACTIVITY IS RIGHT NOW UNTIL 22Z. COULD TEMPORARILY DIP AS LOW AS 2SM AND 2KFT CIGS DURING THAT TIME...BUT OVERALL MVFR VSBYS WITH CIGS ABOVE 1700 FT ARE EXPECTED. AFTER THE STORMS PASS VFR CONDITIONS WITH SCATTERING CLOUDS ARE EXPECTED...ALONG WITH A SHIFT TO NORTHWEST WINDS FOR THIS EVE...THEN NORTHERLY FOR FRIDAY. COULD SEE A FEW SHOWERS BY FRIDAY AFTERNOON AS WELL...BUT CONFIDENCE IS LOW. /OUTLOOK FOR KMSP/ SAT...VFR. WIND WNW 7-10 KTS. SUN...VFR. WIND SSW 10-12 KTS. MON...VFR.
