The radar

The La Crosse radar (KARX), 107 km from the middle of the area, began a volume at 12:43 UTC, the scan nearest the moment this went out.

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

Green Bay/Straub, WI (KGRB), launched 12:00Z, 0.7 hours before the alert went out and 187 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
200 PM CDT WED SEP 21 2005

.DISCUSSION...FORECAST FOCUS IS ON THUNDERSTORM CHCS AND
TIMING TONIGHT INTO THURSDAY...AND AGAIN ON SAT NGT/SUN.
OUR 88D RADAR REMAINS OTS DUE TO AN EQUIPMENT MODIFICATION. IT IS
HOPED WE WILL HAVE IT UP AND TURNING BEFORE THE RAIN ARRIVES LATER
THIS EVENING.

WV IMAGERY SHOWING VIGOROUS MID LEVEL TROF MOVING THROUGH THE
INTERMOUNTAIN REGION WITH A TROPICAL PLUME PUSHING NE AHEAD OF IT.
THIS PLUME ORIGINATES FROM THE DIMINISHING ERN PACIFIC TROPICAL STORM
MAX.

MID LEVEL S/W ENERGY ON THE NOSE OF THIS PLUME TRACKING THROUGH THE
CENTRAL PLAINS THIS AFTN.  ASSOCIATED SFC LOW OVR ERN SDKTA WITH
TROF EXTENDING FROM NE MN TO SW NEB DEPICTED BEST BY 12Z GFS. WITH
TROPICAL CONNECTION...STRONG DIFFERENTIAL THETA-E ADVECTION HITS THE
REGION CENTERED AROUND 06Z TONIGHT. CURRENTLY...SFC THETA-E AXIS
STRETCHING THE INTERSECTION OF IA/SD/NEB NORTHEAST INTO NCNTRL WI.
LI/S DROPPING THERE THIS AFTN AND WITH CU FORMING SHOULD SEE FIRST
SIGNS OF RADAR ECHOES SOON. QPF FROM NAM STILL LOOKS A FEW HOURS TOO
FAST INTO OUR CWA...WITH THE GFS SHOWING THE BEST CONTINUITY FROM RUN
TO RUN AND WITH REALITY. WILL KEEP PCPN TIMING FOCUSED MAINLY
FROM VRY LATE EVENING INTO THE OVERNIGHT HOURS. H7 INDICATING STRONG
OMEGA OVER THE AREA TONIGHT IN IMPRESSIVE REGION OF H7 WARM
ADVECTION. PROXIMITY OF SRN PERIPHERY OF H2 JET SHOULD PROVIDE UPR
LEVEL DIVERGENCE.

SOUNDINGS SHOW LLV CIN IN THE FORM OF A STRONG CAPPING INVERSION.
THIS CAP IS LOW...HOWEVER...SITTING AROUND 2KFT AND SHOULD BE BROKEN
AS FRONT AND CONVECTION PUSH IN FROM THE WEST. NAM SOUNDING SHOW
CAPES OF AROUND 1100 J/KG AND 0-6 BULK SHEAR MAG OF 35-40KT.

SFC FRONT EXITS AROUND 15Z ON THU...MEANWHILE THE PREVIOUSLY
MENTIONED INTERMOUNTAIN S/W COMES THROUGH AROUND 18Z. THE S/W
AND ASSOCIATED STRONG FRONTOGENISIS LAGGING BEHIND THE FRONT SHOULD
KEEP PRECIP GOING STRONG THROUGH MID DAY.  ALTHOUGH THE S/W WILL
HAVE LOST MUCH OF IT/S STRONGER CHARACTERISTICS AS IT MOVES THROUGH
THE CONFLUENT ZONAL FLOW OF THE UPR MIDWEST...IT SHOULD STILL BE A
POTENT FEATURE.  THE GFS...PER USUAL...SUFFERS FROM CONVECTIVE
FEEDBACK AND BLOWS UP 60+UNIT VORT OVR THE AREA AT 18Z THU. THROUGH
WAY OVERDONE...IT HAS THE RIGHT IDEA.

SFC HIGH WILL THEN BUILD AND STRENGTHEN OVER WRN GTLKS AND DRIVES FNT
FAR ENOUGH SOUTH FOR A DRY BUT COOL FRI...WITH NE-E WINDS AND 850
TEMPS DIPPING TO THE SINGLE DIGITS. RETURN FLOW DEVELOPS OVER ERN
PLAINS FRI NIGHT...AND SHIFTS INTO WRN GREAT LAKES SAT...BRINGING
WARMER AIR AND THE CHC FOR TSTMS BACK INTO FORECAST.  THE CHANCE FOR
RAIN WILL INCREASE BY SUNDAY AS ANOTHER LOW PRESSURE SYSTEM MOVES
THROUGH THE GREAT LAKES.
