Verified. The Iowa Environmental Mesonet's Cow matched 6 storm reports to this severe thunderstorm warning; the first came 2 minutes after it went out.

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.

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 La Crosse, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 28, 6:25 PM CDT, 2 hours 25 minutes earlier.

Area forecast discussion, Jun 28, 6:25 PM CDT, 2 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
625 PM CDT SAT JUN 28 2014

.UPDATE...
ISSUED AT 625 PM CDT SAT JUN 28 2014

NUMEROUS SHOWERS AND THUNDERSTORMS ARE TRACKING INTO THE AREA WEST
OF THE MISSISSIPPI RIVER. DESPITE A POTENT SHORTWAVE LIFTING
THROUGH WESTERN IOWA TO PROVIDE PLENTY OF DYNAMICAL
FORCING...ALONG WITH AN INCREASE IN 850MB MOISTURE TRANSPORT
DOWNSTREAM...THE STORMS HAVE FALLEN APART IN ORGANIZATION. PART OF
THE PROBLEM AS REFERENCED IN SPC\S MESO DISCUSSION 1192 IS THE
UNIDIRECTIONAL SOUTHERLY FLOW FROM THE SURFACE INTO THE MID-
LEVELS...WHICH GIVEN THE NORTH-SOUTH ORIENTATION TO THE LINE IS
NOT FAVORABLE FOR ORGANIZED DAMAGING WINDS. MOST OF THE WIND GUSTS
THUS FAR HAVE BEEN OBSERVED IN THE 30-45 MPH RANGE...SO THINKING
THE DAMAGING WIND CONCERN IS DIMINISHING.

FARTHER OUT IN TIME...SOME UNCERTAINTY HAS DEVELOPED FOR SUNDAY.
THE 28.12Z ECMWF...REGIONAL CANADIAN...HI RES ARW/NMM MODELS AND
THE 28.18Z NAM/GFS ARE CONVECTING STORMS SOONER AND FARTHER EAST THAN
WHAT IS IN THE FORECAST. WE COULD BE DEALING WITH SHOWERS AND
STORMS AS EARLY AS 18Z IF THE ECMWF IS CORRECT. THIS WILL BE
LOOKED AT MORE THROUGH THE EVENING TO SEE IF SOME FORECAST
ADJUSTMENTS ARE REQUIRED.

&&

.SHORT TERM...(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 152 PM CDT SAT JUN 28 2014

SEVERE THREAT INCLUDING HEAVY RAINFALL REMAIN THE MAIN CONCERN
THROUGH THE REST OF THIS WEEKEND.

WATER VAPOR LOOP AND RAP ANALYSIS HAS A NEGATIVELY TILTED MID-LEVEL
TROUGH/WEAK SURFACE COLD FRONT EXTENDING FROM WESTERN ND THROUGH THE
CENTRAL PLAINS. FEED OF MOISTURE TRANSPORT AHEAD OF THE TROUGH WAS
PRODUCING SEVERAL LINES OF SHOWERS/THUNDERSTORMS ACROSS MN/IA...AND
INTO THE CENTRAL PLAINS. OTHERWISE...A WARM AND MUGGY AIRMASS WAS IN
PLACE ACROSS THE AREA WITH TEMPERATURES IN THE LOWER 80S AND DEW
POINTS IN THE UPPER 60S TO THE LOWER 70S.

WILL BE WATCHING THE PROGRESSION OF THE MID-LEVEL TROUGH/WEAK
SURFACE COLD FRONT AND CONVECTION THROUGH THE REST OF THIS AFTERNOON
INTO TONIGHT. CONSENSUS OF MESO-WRF MODELS CONTINUE TO ENHANCE
THUNDERSTORM ACTIVITY ALONG AND AHEAD OF THIS TROUGH/FRONT AS IT
MOVES INTO THE AREA LATE THIS AFTERNOON/EARLY EVENING. NAM 0-1KM
MLCAPE IN THE 500-1000J/KG RANGE WITH 0-3KM BULK SHEAR AROUND 20KT.
MEANWHILE... PRECIPITABLE WATER VALUES APPROACHING 2 INCHES.
SO...INGREDIENTS ARE THERE FOR PERHAPS SOME ORGANIZED LINE/S OF
THUNDERSTORMS MOVING INTO THE AREA LATE THIS AFTERNOON AND EARLY
EVENING WITH THE MAIN IMPACT BEING BOUTS OF HEAVY RAINFALL AND
POTENTIAL FOR DAMAGING WINDS. RAP ALSO SHOWING SOMEWHAT ENHANCED NON-
TORNADIC SUPERCELL SIGNATURE FOR PERHAPS A BRIEF SPIN-UP OF AN
ISOLATED TORNADO OR TWO ON THE LEADING EDGE OF THE LINE/S OF
CONVECTION. APPEARS RIGHT NOW THE MAIN SEVERE THREAT WILL BE IN THE
4-10 PM TIME FRAME. APPEARS THE TROUGH AND BULK OF THE
SHOWER/THUNDERSTORMS WILL EXIT THE AREA AFTER MIDNIGHT.

ON SUNDAY...AFTER A BRIEF MORNING LULL IN THE ACTION...PLAN ON
ANOTHER ROUND OF THUNDERSTORMS TO MOVE BACK INTO THE AREA MAINLY
LATER IN THE AFTERNOON INTO SUNDAY NIGHT AS ANOTHER MID-LEVEL TROUGH
INTERACTS WITH THE SURFACE FRONTAL BOUNDARY LAID OUT ACROSS SOUTHERN
WI THROUGH CENTRAL IA. THERE WILL BE AMPLE 0-3KM BULK SHEAR IN THE
30-35KT RANGE AND MUCAPE IN THE 1800-2500J/KG GOING INTO SUNDAY
EVENING FOR A ANOTHER POTENTIAL FOR ORGANIZED LINES OF THUNDERSTORMS
WITH DAMAGING WINDS AND HEAVY RAINFALL. MID-LEVELS WILL ALSO BE IN
COOLING MODE FOR STEEPER LAPSE RATES AND LARGE HAIL POTENTIAL.
ALSO...CANNOT RULE OUT A BRIEF TORNADO OR TWO AS WELL.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 152 PM CDT SAT JUN 28 2014

ANOTHER ROUND OF SEVERE WEATHER/HEAVY RAINFALL LIKELY MONDAY.

MODELS HAVE BEEN COMING INTO BETTER AGREEMENT IN GENERATING A MID-
LEVEL WAVE OVER THE CENTRAL PLAINS AND RACING ITO NORTHEAST ACROSS
THE STALLED OUT BOUNDARY RUNNING FROM SOUTHERN WI INTO CENTRAL IA.
MODEL CONSENSUS 0-3KM MUCAPE RUNNING SOMEWHERE AROUND 1200J/KG
ALONG/NORTH OF I-94...TO NEAR 3000J/KG ACROSS NORTHEAST IA. THE NAM
IS THE MOST BALLISTIC WITH CAPE NEARING 5500J/KG BY AFTERNOON ACROSS
NORTHEAST IA. NAM/GFS/ECMWF ALL INDICATING AMPLE 0-3KM BULK SHEAR IN
THE 35-55KT RANGE. SO...LOOKS LIKE ANOTHER SHOT FOR SEVERE
THUNDERSTORMS WITH HEAVY RAINFALL. TORNADO/LARGE HAIL THREAT ALSO
LOOKS HIGHER FOR PORTIONS OF SOUTHWEST WI INTO NORTHEAST IA WHERE
NAM INDICATES STORM RELATIVE HELICITY VALUES IN THE 500-700 RANGE.
LOOK FOR THE BULK OF THIS CONVECTION TO PUSH EAST OF THE AREA DURING
THE MID-LATE EVENING HOURS.

FOR TUESDAY THROUGH THURSDAY...GFS/ECMWF INDICATING COOLER/CYCLONIC
FLOW DOMINATING THE REGION. TUESDAY LOOKS PRIME FOR SOME INSTABILITY
SHOWERS/ISOLATED THUNDERSTORMS MAINLY TUESDAY AFTERNOON WITH COLDEST
POOL OF AIR ALOFT.

FOR FRIDAY/SATURDAY...SOME DIFFERENCES BETWEEN THE ECMWF/GFS ARISE
AS THE ECMWF BUILDS A FLAT RIDGE INTO THE REGION WHILE THE GFS
MAINTAINS COOLER/BROAD CYCLONIC FLOW. EITHER WAY...LOOKS LIKE  A
COUPLE ROUNDS OF SHOWERS/THUNDERSTORMS WILL BE POSSIBLE.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 625 PM CDT SAT JUN 28 2014

NUMEROUS SHOWERS AND THUNDERSTORMS ENCOMPASS SOUTHEAST MN AND
NORTHEAST IA...AHEAD OF A LOW PRESSURE TROUGH ALONG I-35. SOME OF
THE STORMS HAVE PRODUCED GUSTS UPWARDS OF 40 KT...ALONG WITH
IFR/MVFR VISIBILITIES AND AT LEAST SCT IFR/MVFR CEILINGS.
ANTICIPATING THESE TO MOVE THROUGH THE TAF SITES DURING THE NEXT
FEW HOURS...FOLLOWED BY SOME LINGERING SHOWERS UNTIL ABOUT 08Z
WHEN THE TROUGH PASSES. IN THE WAKE OF THE TROUGH...PLENTIFUL
MOISTURE EXISTS NEAR THE GROUND WHICH WILL LIKELY RESULT IN A
MVFR STRATUS DECK AND MVFR BR. DAYTIME MIXING SHOULD HELP GET RID
OF THE MVFR CONDITIONS BY 16Z. FOCUS THEN TURNS TO ANOTHER TROUGH
OF LOW PRESSURE TRACKING ACROSS MN AND IA DURING THE AFTERNOON
HOURS. THERE IS A GENERAL MODEL CONSENSUS FOR STORMS TO FORM ON
THIS TROUGH...BUT WHEN IS THE QUESTION. SOME MODELS BRING STORMS
THROUGH THE TAF SITES BETWEEN 18-21Z...OTHERS WAIT CLOSER TO 00Z.
SINCE THERE APPEARS TO BE A TREND OF SOONER...HAVE PUT A VCTS AT
RST STARTING AT 18Z AND AT LSE STARTING AT 20Z...CONTINUING THEN
THROUGH THE REST OF THE TAF PERIOD. COULD BE STRONG WIND GUSTS AND
BRIEF HEAVY RAIN WITH THESE STORMS AS WELL...ESPECIALLY IF THEY
ARE LATER IN THE DAY.

&&

.HYDROLOGY...
ISSUED AT 152 PM CDT SAT JUN 28 2014

PLAN ON PERIODS OF HEAVY RAINFALL THROUGH THE REST OF THE WEEKEND
AND AGAIN ON MONDAY AS SEVERAL ROUNDS OF THUNDERSTORMS ARE FORECAST
TO MOVE THROUGH. DUE TO MOSTLY TRANSITORY NATURE OF THE
CONVECTION...FLASH FLOODING WILL LIKELY END UP BEING MORE OF A
LOCALIZED THREAT. HOWEVER...IF TRAINING OCCURS...HEAVY RAINFALL
COULD BE PROBLEMATIC. THIS COULD BE THE ISSUE MORE ON MONDAY. WILL
HAVE TO WATCH EVOLUTION OF THIS ACTIVITY AND POTENTIAL FOR A FLASH
FLOOD WATCH

PLAN ON THE MAIN STEM OF THE MISSISSIPPI TO REMAIN HIGH THROUGH NEXT
WEEK DUE TO ADDITIONAL RAINFALL THROUGH MONDAY.
