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, 8.6 hours before the alert went out and 135 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, Aug 19, 3:11 PM CDT, 26 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
311 PM CDT FRI AUG 19 2011

.SHORT TERM...

MODELS SHOWING BROAD TROF DEVELOPING OVER LAKES REGION AS SERIES
OF SHORT WAVES MOVE THROUGH REGION. INITIAL TROF NOW OVER WESTERN
ONTARIO...WITH SECONDARY SHORT WAVE SEEN IN WATER VAPOR SOUTHERN
LAKE SUPERIOR. ASSOCIATED SURFACE FRONT OVER WESTERN WI ATTM.
CONVERGENCE BEST NORTH END OF FRONT CLOSE TO BEST UPPER
SUPPORT...DEEP LAYER SHEAR. EXPECT ACTIVITY TO DIMINISH WITH
SUNSET AS INSTABILITY WAINS. HRRR MODEL HAS SHOWN GOOD RUN TO RUN
CONSISTENCY WITH THIS FEATURE. UPPER JET SHIFTING EAST ALONG
U.S./CANADIAN BORDER. LARGE AREA OF SHOWERS MOVING EAST THROUGH
DAKOTAS ATTM ASSOCIATED WITH RRQ OF JET AND AREA OF FGEN FORCING.
THIS FORCING EXPECTED TO MOVE EAST INTO CWA LATE TONIGHT...
DROPPING SOUTH DURING DAY SAT. WILL GO WITH ISOLATED AND SCATTERED
WORDING TO COVER BOTH PERIODS. INSTABILITY LIMITED WITH CAPES
BELOW 400. WITH REMOVE THUNDER WORDING FOR SAT.

.LONG TERM...SATURDAY NIGHT THROUGH NEXT FRIDAY.

THE GFS ENSEMBLE MEAN INDICATES LONGWAVE TROUGHING MOVING ACROSS THE
GREAT LAKES LATE THIS WEEKEND AND PROCEEDING TO THE NE CONUS NEXT
WEEK.  DIFFERENT FROM THE PAST TWO DAYS OF RUNS...MEDIUM RANGE
MODELS NOW PORTRAY A REINFORCING SHORTWAVE DROPPING SE ACROSS THE
GREAT LAKES IN THE TUESDAY NIGHT THROUGH WEDNESDAY NIGHT TIME
PERIOD.  FINER DETAILS LIKE THIS REMAIN PROBLEMATIC IN THE EXTENDED
FORECAST SO WILL CONTINUE TO LEAN ON THE BETTER VERIFYING ECMWF AND
THE GFS ENSEMBLE TO WEED OUT THE UNCERTAINTY OF THESE FINER DETAILS.

SATURDAY NIGHT THROUGH SUNDAY NIGHT...SLOW MOVING COLD FRONT WILL BE
EXTENDING ACROSS LOWER MICHIGAN TO NORTHERN ILLINOIS AT THE START OF
THE PERIOD.  FGEN ALONG AND BEHIND THE BOUNDARY WILL BE EXITING AS
WELL...AND CHANCES SEEM SMALL ENOUGH TO KEEP POPS OUT OF THE
FORECAST FOR E-C WISCONSIN.  MEANWHILE...SHORTWAVE RIDING WITHIN THE
LEFT EXIT REGION OF AN UPPER JET STREAK WILL BE DIVING SE OVER THE
NORTHERN PLAINS AND INTO THE NORTHWEST GREAT LAKES.  THE LATEST 12Z
GUIDANCE IS A LITTLE MORE BULLISH WITH THIS WAVE...ESPECIALLY THE
NAM...WHICH GENERATES A FAIRLY BIG SLUG OF PRECIP OVER FAR NORTHERN
WISCONSIN AND THE U.P.  DO NOT BUY IT TOO MUCH...BUT COULD BUY JUST
A FEW SPOTTY SHOWERS AND WILL ADD TO THE FORECAST.  UPPER TROUGH
WILL THEN SWING ACROSS THE NORTHERN FORECAST AREA ON SUNDAY.  WITH
DIURNAL HEATING...LOW LEVEL LAPSE RATES WILL BECOME QUITE
STEEP...WHICH WILL HELP PRODUCE INSTABILITY ON THE ORDER OF 300-500
J/KG OF ML CAPE IN THE NAM.  CONVECTIVE TEMPS WILL ONLY RANGE FROM
THE MID 60S TO LOWER 70S WHICH SHOULD BE EASILY SURPASSED.  SCT
COVERAGE TYPE POPS LOOKS JUSTIFIABLE.  MAY SEE A FEW SHOWERS LINGER
BEYOND 00Z BY A COUPLE HOURS OVER FAR NE WISCONSIN...WHICH THE
INHERITED FORECAST ALREADY SHOWS.  THEREAFTER...WILL SEE SOME
PARTIAL CLEARING.  HIGHS IN THE LOW TO MID 70S ON SUNDAY.

NEXT MONDAY THROUGH NEXT FRIDAY...HIGH PRESSURE WILL BE AT THE
SURFACE ON MONDAY WITH UPPER TROUGHING MOVING TO THE EASTERN GREAT
LAKES AND WARM ADVECTION SHIFTING INTO THE NORTHERN MISSISSIPPI
VALLEY.  THEREFORE...LOOKS LIKE A DRY DAY WITH HIGHS IN THE UPPER
70S TO LOWER 80S.  WEAK SHORTWAVE THEN IS STILL PROGGED TO DIVE SE
INTO NORTHERN ILLINOIS LATE MONDAY NIGHT AND TUESDAY.  PRIMARY
FORCING REMAINS TO THE SOUTH OF THE AREA...BUT WILL STILL HAVE WEAK
WARM ADVECTION.  WILL LET THIS WORK ANOTHER FORECAST CYCLE BEFORE
INSERTING POPS.  REINFORCING SHORTWAVE THEN DROPS SOUTHEAST OVER THE
GREAT LAKES LATE TUESDAY NIGHT THROUGH EARLY WEDNESDAY NIGHT...WHICH
WILL LEAD TOWARDS UNSETTLED CONDITIONS.  WILL MAKE SUBTLE TWEAKS BY
INCREASING POPS WEDNESDAY AND DECREASING POPS A BIT WEDNESDAY NIGHT
WITHOUT CHANGING THE GIST OF THE FORECAST.  COOL HIGH PRESSURE THEN
BUILDS IN FOR THURSDAY AND FRIDAY.
&&

.AVIATION...CONTINUED THOUGHTS FOR SCATTERED TSTM ACTIVITY THROUGH
03Z AS COLD FRONT MOVES THROUGH NORTHERN WI WITH ATMOSPHERE
STABILIZING AFTER THAT. AREA OF SHOWERS MOVING THROUGH DAKOTAS
EXPECTED TO MOVE INTO STATE LATE TONIGHT...LINGER INTO SAT MORNING
OVER SOUTHERN CWA.
&&

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
