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 6, 4:05 AM CDT, 2 hours 30 minutes earlier.

Area forecast discussion, Jun 6, 4:05 AM CDT, 2 hours 30 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
405 AM CDT MON JUN 6 2011

.SHORT TERM...TODAY THROUGH WEDNESDAY

AT 3 AM...A WARM FRONT EXTENDED FROM SIOUX FALLS SOUTH DAKOTA TO
MUSCATINE IOWA. SOME ELEVATED SHOWERS AND STRONG THUNDERSTORMS
HAVE DEVELOPED ACROSS SOUTHEAST MINNESOTA AND SOUTHWEST WISCONSIN.
THESE THUNDERSTORMS ARE ASSOCIATED WITH A SHORT WAVE TROUGH THAT
IS MOVING SOUTHEAST THROUGH SOUTHERN MINNESOTA AND EASTERN IOWA.
AHEAD OF THIS SHORT WAVE TROUGH...THERE IS A 30 KNOT LOW LEVEL
JET WHICH IS AIDING WITH THE MOISTURE TRANSPORT INTO THE REGION.
WITH MOST UNSTABLE CAPES ARE RUNNING BETWEEN 1500 AND 2500 J/KG...
THERE IS PLENTY OF INSTABILITY FOR THUNDERSTORMS AND WITH EFFECTIVE
SHEAR RUNNING BETWEEN 40 TO 60 KNOTS A FEW OF THESE THUNDERSTORMS
HAVE BEEN ABLE TO BECOME SEVERE. WITH DCAPE RUNNING LESS THAN
700 J/KG AND MEAN LAYER CINS RUNNING BETWEEN 100 AND 300
J/KG...THE WIND AND TORNADO THREAT WITH THESE SUPERCELLS LOOKS
REALLY LOW. THIS LEAVES LARGE HAIL THE PRIMARY THREAT WITH THESE
THUNDERSTORMS. WITH PRECIPITABLE WATER RUNNING AROUND 1.5 INCHES...
THE THUNDERSTORMS WILL BE HIGHLY EFFICIENT AT PRODUCING HEAVY RAIN.
FORTUNATELY THE STORMS ARE MOVING AT ABOUT 40 MPH AND THERE HAS
BEEN LITTLE TRAINING...SO THE FLOODING THREAT LOOKS MINIMAL AT
THIS TIME.

THE 06.00Z MODELS ARE IN FAIRLY GOOD AGREEMENT THAT THE WARM FRONT
WILL CONTINUE TO LIFT NORTHWARD TOWARD THE INTERSTATE 90 CORRIDOR
TODAY...INTO CENTRAL MINNESOTA AND CENTRAL WISCONSIN TONIGHT. SOUTH
OF THIS FRONT...THE AIR MASS QUICKLY BECOMES CAPPED AS WARM AIR
MOVES IN ALOFT. HIGH TEMPERATURES IN THESE AREAS WILL CLIMB INTO
THE LOWER AND MID 90S. THESE TEMPERATURES ARE WARM ENOUGH FOR A
FEW RECORD HIGH TEMPERATURES TO BE EITHER TIED OR SET. HEAT
INDICES WILL APPROACH 100 ACROSS NORTHEAST IOWA AND SOUTHWEST
WISCONSIN. MEANWHILE NORTH OF THIS FRONT...THERE WILL CONTINUE TO
BE A CHANCE FOR SHOWERS AND THUNDERSTORMS AS WEAK WAVES ROUND THE
RIDGE. WITH PLENTY OF INSTABILITY AND SHEAR...A FEW OF THESE
THUNDERSTORMS COULD BECOME SEVERE.

ON TUESDAY...THE 850 MB HPC ANOMALIES ARE RUNNING AROUND
2.5 STANDARD DEVIATIONS ABOVE NORMAL. BUFKIT SOUNDINGS SUGGEST
THAT BY MID AFTERNOON MUCH OF THE AREA COULD BE MIXING INTO THE
700 TO 750 MB RANGE. USING THE MIX DOWN TOOLS WITH A SUPER
ADIABATIC...SURFACE TEMPERATURES WILL BE IN THE MID AND UPPER 90S
WITH A FEW LOCATIONS AROUND 100 DEGREES. HEAT INDICES WILL LIKELY
RUN BETWEEN 100 AND 110. IF THIS TREND CONTINUES...A HEAT ADVISORY
WILL LIKELY BE REQUIRED AND IT WILL LIKELY HAVE TO BE EXTENDED
INTO WEDNESDAY.

ON WEDNESDAY...THE HIGH TEMPERATURES FORECAST IS RATHER
TRICKY...BECAUSE MANY OF THE MODELS PRODUCE PRECIPITATION ALONG A
PRE-FRONTAL TROUGH. FOR THE TIME BEING...TOOK A CONSERVATIVE
APPROACH ON THEM. HOWEVER IF THIS PRECIPITATION DOES NOT OCCUR
EARLY IN THE DAY...THESE TEMPERATURES WILL LIKELY HAVE TO BE
RAISED.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY

A STRONG COLD FRONT WILL MOVE THROUGH THE REGION ON WEDNESDAY
NIGHT. THIS FRONT WILL BRING A RETURN TO BELOW NORMAL TEMPERATURES
FOR THE REMAINING WEEK. WHILE THE MODELS HAVE BEEN VERY CONSISTENT
WITH THIS...THEY CONTINUE TO STRUGGLE WITH THE TIMING OF SHORT
WAVE TROUGHS COMING OUT OF THE WESTERN UNITED STATES TROUGH AND
THIS GREATLY AFFECTS THE TIMING OF PRECIPITATION. DUE TO THIS...
A BROAD BRUSH APPROACH WAS USED FOR THE PRECIPITATION CHANCES
THROUGH THIS TIME PERIOD.

&&

.AVIATION...TODAY INTO TUESDAY

THE MAIN CONCERN OVER THE NEXT 24 HOURS IS ON THE THUNDERSTORM
CHANCES ACROSS THE TAF SITES.  A WARM FRONT...THAT CURRENTLY ARCHES
FROM SOUTHERN MINNESOTA SOUTHEAST TOWARD THE MISSISSIPPI RIVER ON
DOWN TOWARD INDIANAPOLIS...WILL LIFT NORTHWARD TODAY WITH SHOWERS
AND THUNDERSTORMS EXPECTED TO DEVELOP ALONG AND NORTH OF THIS
FRONT.  SHOWERS AND THUNDERSTORMS HAVE DEVELOPED EARLY THIS MORNING
ACROSS SOUTHEAST MINNESOTA AND WILL TRACK TO THE SOUTHEAST ALONG
IT.  THE BETTER CHANCE FOR ANY STORMS TO ENTER THE TAF DOMAINS OF
RST AND LSE WILL BE LATER TODAY AS A TROUGH OF LOW PRESSURE TRACKS
THROUGH THE REGION. BESIDES THESE THUNDERSTORM CHANCES...FLIGHT
CONDITIONS WILL BE VFR THROUGHOUT WITH WINDS BECOMING FAIRLY GUSTY
OUT OF THE SOUTHWEST ON TUESDAY.

&&

.CLIMATE...TODAY THROUGH WEDNESDAY

RECORD HIGH TEMPERATURES WILL BE POSSIBLE SOUTH OF INTERSTATE 90
TODAY...AND ACROSS THE ENTIRE AREA ON TUESDAY. ON WEDNESDAY...MANY
LOCATIONS HAVE RECORD TEMPERATURES AROUND 100 DEGREES...SO NOT
EXPECTING TOO MANY /IF ANY/ RECORDS ON THIS DATE.
