Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched 4 storm reports to this severe thunderstorm warning; the first came 3 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.

The nearest sounding before it

Green Bay/Straub, WI (KGRB), launched 12:00Z, 7.3 hours before the alert went out and 150 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...UPDATED
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
1133 AM CDT THU JUN 27 2013

.UPDATE...

WATER VAPOR IMAGERY IS SHOWING A FEW NOTABLE AREAS THIS MORNING.
THERE IS A STRONG SHORTWAVE PRODUCING THUNDERSTORMS IN SOUTHEAST
NEBRASKA AND THAT WILL NOT AFFECT SOUTHERN WISCONSIN TODAY. THERE IS
A DISTINCT VORT MAX/CIRCULATION OVER NORTHERN LAKE SUPERIOR AND
CONVECTION IS FIRING UP WITH THAT DISTURBANCE OVER NORTHERN
WISCONSIN ALREADY. A 10 KNOT UPPER LEVEL STREAM WILL BE PUSHING INTO
NORTHWEST WISCONSIN THIS AFTERNOON...WHICH WILL HELP TO
INTENSIFY/DIG THE UPPER LOW OVER SOUTHEAST MANITOBA AND SOUTHWEST
ONTARIO INTO ALL OF THE GREAT LAKES BY LATER TONIGHT.

ML CAPES WILL BE IN THE 1500-2000 J/KG RANGE...ALONG WITH
STRAIGHT-LINE HODOGRAPHS WITH 30 KNOTS OF BULK SHEAR. THIS SCENARIO
IS A DECENT SET-UP FOR SPLITTING CELLS...ISOLATED SEVERE HAIL AND
DAMAGING WINDS. THE SPC STORM-SCALE ENSEMBLE OF OPPORTUNITY /SSEO/
DEPICTS NORTHERN...EAST CENTRAL AND SOUTHEAST WISCONSIN WITH THE
BEST CHANCE FOR REFLECTIVITY GREATER THAN 40 DBZ...UPDRAFT HELICITY
GREATER THAN 25 M2/S2...AND UPDRAFT SPEED GREATER THAN 10 M/S.

SPC CONTINUES TO HAVE THE MKX AREA IN A SLIGHT RISK TODAY. PER
MESOSCALE SHORT-TERM MODELS...THUNDERSTORMS ARE EXPECTED TO
DEVELOP/SPREAD INTO SOUTH CENTRAL WI AROUND 19Z/2PM TODAY AND BE
CONFINED TO SOUTHEAST WI BY 23Z/6PM. THUNDERSTORMS SHOULD QUICKLY
DISSIPATE/MOVE EAST OF WI BY DARK.

IT APPEARS THE BEST CHANCE FOR MID/LATE AFTERNOON THUNDERSTORMS WILL
LAND IN SOUTHEAST WISCONSIN...INCLUDING MILWAUKEE. THERE WILL BE
SLIGHTLY ENHANCED CONVERGENCE THERE DUE TO THE WEAK SURFACE TROUGH
AND LAKE BREEZE BOUNDARY. THOSE ATTENDING OUTDOOR EVENTS SHOULD BE
ON ALERT FOR CHANGING WEATHER CONDITIONS.

&&

.AVIATION/18Z TAFS/...

LAKE BREEZE DEVELOPED ALREADY BUT WILL NOT PUSH VERY FAR
INLAND...NOT QUITE TO ENW. SCT-BKN040-050 CUMULUS CONGESTUS WILL
FORM FOR THE AFTERNOON WITH SCT TSTORMS EXPECTED ACROSS THE REGION
AS A SFC TROUGH MOVES THROUGH. SOME STORMS COULD BE SEVERE...
ESPECIALLY EAST OF MADISON...INCLUDING FLD...SBM... UES...MKE...RAC
AND ENW. SKIES WILL BECOME MO CLEAR TO PARTLY CLOUDY FOR TNT WITH
VFR CONDITIONS.

&&

.PREV DISCUSSION... /ISSUED 400 AM CDT THU JUN 27 2013/

TODAY AND TONIGHT...FORECAST CONFIDENCE MEDIUM TO HIGH

SHOWERS EARLY THIS AM HAVE MOSTLY DISSIPATED AS THEY ENCOUNTERED
STABLE CONDITIONS IN FAR ERN WI. RADIATIONAL COOLING WITHIN A MOIST
LOW LEVEL AIRMASS IS CAUSING AREAS OF FOG THIS MORNING BUT LESSER
OVER THE WRN CWA WHERE WNWLY WINDS ARE PICKING UP JUST ABOVE THE
SFC.

OTHERWISE...AN 80 KT JET STREAM DIVING SEWD ACROSS THE NRN PLAINS
AND INTO WI WILL HELP DIG THE UPPER LOW OVER SRN MANITOBA AND SW
ONTARIO INTO ALL OF THE GREAT LAKES BY LATER TNT. THE ASSOCIATED SFC
TROUGH WILL PASS THIS AFTERNOON WITH MLCAPES RANGING FROM 1500-2000
J/KG ALONG WITH STRAIGHT LONG HODOGRAPHS. THE AREA OF BEST FOCUS
WILL BE TOWARD CENTRAL WI WHERE THE INITIAL VORT MAX PASSES THROUGH
THE STATE. THE ENHANCED CONVERGENCE OF THE SFC TROUGH AND LAKE
BREEZE WILL BRING MORE OF A FOCUS TO ERN WI AS WELL. GIVEN DEGREE OF
CAPE AND SHEAR...SPC SLIGHT RISK LOOKS GOOD. TSTORMS WILL BEGIN TO
DISSIPATE TOWARD SUNSET WITH LOSS OF HEATING AND DRIER AIR ARRIVING
ON NWLY SFC WINDS. THE NWLY WINDS WILL PREVENT ANY FOG FOR TNT WITH
PCPN CHANCES HOLDING OFF UNTIL FRI WHEN THE UPPER LOW SETTLES CLOSER
TO THE AREA.

FRIDAY AND SATURDAY...FORECAST CONFIDENCE...MEDIUM TO HIGH

A PAIR OF SHORTWAVES ARE EXPECTED TO MOVE THROUGH FRIDAY AND
SATURDAY...BRINGING MORE SHOWER/STORM CHANCES TO SOUTHERN WISCONSIN.
THE BULK OF THE ACTIVITY SHOULD BE DIURNALLY DRIVEN...THOUGH A FEW
SHOWERS/STORMS MAY LINGER THROUGH FRIDAY NIGHT. OVERALL AIRMASS
WILL BE DRIER WITH MORE FLOW...SO NOT EXPECTING A HEAVY RAIN
THREAT...A MUCH DIFFERENT SETUP THAN THE LAST FEW DAYS. STILL
LOOKS LIKE COOLING TEMPS INTO THE WEEKEND UNDER NORTHWEST FLOW.

SUNDAY THROUGH WEDNESDAY...FORECAST CONFIDENCE...MEDIUM TO HIGH

LOOKS DRY AND PLEASANT SUNDAY AND MONDAY WITH HIGH PRESSURE FINALLY
RETURNING TO THE AREA. COULD SEE A FEW SHOWERS AND STORMS RETURN BY
TUESDAY NIGHT OR WEDNESDAY...THOUGH CHANCE SEEMS FAIRLY LOW AT THIS
POINT. SHOULD SEE TEMPS A FEW DEGREES BELOW NORMAL THROUGH THE FIRST
HALF OF NEXT WEEK.

AVIATION/12Z TAFS/...FOG WILL PREVAIL THIS AM AT THE TAF SITES WITH
ONLY MVFR VSBYS AT KMSN...WHILE VSBYS WILL RANGE MVFR TO IFR AT KUES
AND KMKE...AND 1/4 MILE TO 2 MILES AT KENW. BRIEF PERIODS OF LOW
STRATUS ARE POSSIBLE WITH THE FOG. THE FOG IS SHALLOW HOWEVER AND
SHOULD BURN OFF QUICKLY BY 8 OR 9 AM. SCT-BKN040-050 CUMULUS
CONGESTUS WILL THEN FORM FOR THE AFTERNOON WITH SCT TSTORMS EXPECTED
ACROSS THE REGION AS A SFC TROUGH MOVES THROUGH. SKIES WILL BECOME
MO CLEAR TO PARTLY CLOUDS FOR TNT WITH VFR CONDITIONS.
