What forecasters said that day

The local office's own words before this tornado 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 tornado warning went out at Aug 18, 2:25 PM CDT, 1 hour 53 minutes earlier.

Area forecast discussion, Aug 18, 2:25 PM CDT, 1 hour 53 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
225 PM CDT THU AUG 18 2005

.SHORT TERM...TONIGHT THROUGH SUNDAY

THE FORECAST CONCERNS CONTINUE TO FOCUS ON THE CONVECTIVE
POSSIBILITIES FOR THE NEXT COUPLE DAYS.

A 500 MB SHORTWAVE TROUGH WILL LIFT NORTHEAST ACROSS THE REGION THIS
EVENING...MOVING OVER THE EASTERN GREAT LAKES ON FRIDAY AFTERNOON.
AT THE SFC...AN ASSOCIATED AREA OF LOW PRESSURE WILL ALSO TRACK
NORTHEAST...PUSHING ITS WARM FRONT WITH IT. THESE WEATHER FEATURES
WILL WORK WITH THE AVAILABLE INSTABILTY AND GOOD WIND SHEAR TO
CONTINUE TO SPARK SHOWERS AND STORMS THROUGH THE EVENING...CLEARING
OUT OVERNIGHT AS THE WAVE KICKS EAST. THE SHEAR AND INSTABILITY ARE
SUFFICIENT ENOUGH FOR SEVERE WEATHER WITH THE STORMS EARLY THIS
EVENING.

ON FRIDAY...SOME MINOR RIDGING WILL WORK ACROSS THE UPPER
MISSISSIPPI RIVER VALLEY...AHEAD OF YET ANOTHER 500 MB SHORTWAVE
TROUGH. SOME BRIEF CLEARING IS LIKELY BEFORE CLOUDS FROM THIS NEXT
SYSTEM FILTER BACK ACROSS THE AREA. THIS IS IMPORTANT IN THAT THE
MORE SUN...THE MORE INSTABILITY. CURRENTLY...THE MODELS POINT TO
AROUND 3000 J/KG OF SBCAPE BUILDING BY THE AFTERNOON. WITH WIND
SHEAR ALSO RATHER HIGH...50 KTS OF 0-6 KM...SEVERE WEATHER WILL BE
POSSIBLE WITH ANY STORM THAT DEVELOPS. AT THE SFC...THE MAIN FRONTAL
BOUNDARY LOOKS TO WORK INTO NORTHWEST WI AND EASTERN IOWA BY EARLY
EVENING...MOVING OVER THE EASTERN GREAT LAKES BY SAT MORNING. ONE
DRAWBACK CONTINUES TO BE THE EXPECTED POSITIONING OF THE LOW LEVEL
JET AND MOISTURE TRANSPORT FOR THE EVENING AND NIGHT TIME HOURS.
INITIALLY THESE POINT INTO THE HEART OF THE FORECAST AREA FOR THE
AFTERNOON...BUT THEN TAKE A QUICK TURN TO THE EAST...NOSING INTO THE
EASTERN GREAT LAKES OVERNIGHT. THIS WOULD THEREFORE MOVE THE BEST
FOCUS FOR SHOWERS/STORMS INTO THAT AREA. STILL...CERTAINLY ENOUGH
DYNAMICS AND INSTABILITY THAT SHOWERS AND STORMS SHOULD DEVELOP
AHEAD OF THE SHORTWAVE AND NEAR THE SFC FRONT ON FRI
AFTERNOON...MOVING EAST THEN FOR THE NIGHTTIME HOURS.
CURRENTLY...BEST TIMING ESTIMATE FOR THE FORECAST AREA IS FROM LATE
AFTERNOON INTO THE EARLY OVERNIGHT HOURS. MAIN SEVERE THREAT WOULD
BE EARLY EVENING.

SATURDAY...THE TROUGH AXIS WILL SLIDE EAST...WHILE THE SFC LOW LIFTS
INTO JAMES BAY. SOME LOW LEVEL COLD AIR ADVECTION AND LINGERING
MOISTURE WILL LEAD TO SOME CU DEVELOPMENT...BUT THE BULK OF THE
SATURATION POST LOW LOOKS TO BE WELL NORTH...ACROSS NORTHERN MN INTO
SOUTHERN CANADA. DECENT LAPSE RATES OF AROUND 7 C/KM FOR SAT
AFTERNOON OVER NORTHERN WI COULD LEAD TO SOME SHOWERS/ISOLATED STORM
DEVELOPMENT. TQ INDEX HINTS AT THIS TOO. THE BULK OF THE FORECAST
AREA SHOULD STAY CLEAR OF THESE CHANCES...ALTHOUGH SMALL POPS MAY BE
WARRANTED FOR THE FAR NORTH.

A SFC HIGH WILL BUILD INTO THE REGION FOR SUNDAY...AND BRING A SUNNY
AND RELATIVELY COOL END TO THE WEEKEND. SUNDAY WILL LIKELY HAVE MORE
OF A FALL FEEL TO IT...RATHER THAN SUMMER.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY

FAIRLY PROGRESSIVE PATTERN FOR THE REGION FOR THE END OF THE WEEKEND
THROUGH THE START OF NEXT WEEK. A 500 MB RIDGE WILL BUILD ACROSS THE
UPPER MISSISSIPPI RIVER VALLEY BY SUNDAY NIGHT...WITH THE AXIS
SLIDING RELATIVELY QUICKLY THROUGH...EXITING EAST BY WEDNESDAY
MORNING. ANOTHER SHORTWAVE THROUGH WILL THEN APPROACH THE REGION
FROM THE NORTHERN PLAINS BY THURSDAY NIGHT. AT THE SFC...AN AREA OF
HIGH PRESSURE WILL MOVE OVER THE REGION...IN TANDEM WITH THE UPPER
LEVEL RIDGE...ON SUNDAY...AND STICK AROUND INTO TUESDAY.
DRY...QUIET WEATHER SHOULD RESULT. SOME MORNING VALLEY FOG ALSO
LIKELY ON A COUPLE OF THOSE MORNINGS. TEMPERATURES WILL BE
RELATIVELY COOL...STARTING TO WARM AGAIN FOR WED AND THU AS THE HIGH
PASSES EAST. THE NEXT BEST CHANCE FOR RAIN WILL COME LATER THU...AS
THE SHORTWAVE AND ACCOMPANYING SFC FRONT TRACKS IN.
