What was reported inside it

Time	Report	Where	Remark
Jul 27, 7:45 PM CDT	FUNNEL CLOUD	Lac Du Flambeau, WI

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

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

Area forecast discussion, Jul 27, 3:31 PM CDT, 4 hours before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
331 PM CDT TUE JUL 27 2010

.SHORT TERM...TONIGHT AND WEDNESDAY.

FORECAST CONCERNS ON PCPN POTENTIAL WITH ADVANCING COLD FRONT.
MCV FROM OVERNIGHT CONVECTION AND LLVL JET HAS MAINTAINED
CONVECTION THROUGH THE DAY OVER CENTRAL INTO NORTHEAST WI.
QUESTION IS WHAT THE DAYS RAIN HAS DONE TO POTENTIAL FOR
ADDITIONAL STORMS. VARIETY OF BOUNDARIES LEFT BEHIND IN ADDITION
TO WARM FRONT VCNTY MSP AND COLD FRONT WESTERN MN. HAVE TRENDED
TOWARDS SCENARIO PORTRAYED IN RAPID UPDATE RUC...WITH DEVELOPMENT
WESTERN WI/EASTERN MN...AND ADVANCING LINE OVERNIGHT WITH THE COLD
FRONT. STILL CAPPED A BIT IN MSP AREA GIVEN 18Z SOUNDING...THOUGH
NO INHIBITION AND 1200 CAPE IN GRB. SLIGHT RISK REMAINS FOR HAIL AND
DAMAGING WINDS OVER CENTRAL AND NORTHEAST WI...WITH INCREASING
SHEAR AS JET SINKS SOUTH INTO WESTERN LAKES. PRECIP WATERS STILL IN 1.5
TO 2 INCH RANGE WITH ONE INCH RAINFALL AMOUNTS ALREADY REPORTED IN
CENTRAL WI THIS AFTERNOON. POTENTIAL FOR 1 TO 1.5 INCH AMOUNTS
OVER CWA TONIGHT...NAM/RUC POINT TO NORTHERN WI...THOUGH
CONFIDENCE IN FORECAST LOW.

FRONT TO MOVE THROUGH EARLY MORNING HOURS. 850 FLOW SHIFTS NW
WITH DRIER CONDITIONS BY AFTERNOON.

.LONG TERM...WEDNESDAY NIGHT THRU NEXT TUESDAY. SURFACE HIGH
PRESSURE AREA TO DOMINATE THE AREA/S WEATHER INTO FRIDAY. IN
GENERAL...THE SURFACE HIGH PRESSURE AREA IS NEARLY STATIONARY OVER
THE GREAT LAKES REGION WHILE THE RETURN FLOW ON THE BACK SIDE
OF THE HIGH REMAINS OVER THE NORTHERN PLAINS. MODELS HAVE BEEN
ATTEMPTING TO SLIDE SOME PCPN INTO THE AREA FROM THE WEST FRIDAY
INTO SUNDAY PERIOD. THIS MORNING MODEL RUNS HAVE TRENDED WITH
A FRONTAL BOUNDARY SHIFT NORTH INTO IOWA LATER FRIDAY AS A SHORT
WAVE TROF WITH A RRQ REGION OF THE UPPER JET SLIDES SEWD OVER OR
NEAR THE FORECAST AREA. GFS IS VERY AGGRESSIVE WITH THIS FEATURE
WHILE THE NAM KEEPS THESE DYNAMICS FURTHER SOUTH AND WEST.
AT THIS TIME WILL CONFINE BEST CHC OF RAIN FOR AREAS SOUTH AND
WEST OF THE AREA LATE FRIDAY INTO THE FRIDAY NIGHT PERIOD. REMOVED
THE AFTERNOON CHC FOR SATURDAY...MAY BE NEEDED LATER ON BUT THE THREAT
OF THIS BOUNDARY SHIFTING TOWARD TOWARD THE REGION IS
QUESTIONABLE. DUE TO LACK OF CONSISTENCY WITH FEATURES FOR FOCUS
OF CONVECTION...AFTER FRIDAY NIGHT WILL LEAN TOWARD A DRIER
FORECAST UNTIL THE MONDAY NIGHT INTO TUESDAY TIME WHERE MDM PROGS
ARE IN RELATIVELY GOOD AGREEMENT THAT FAR OUT WITH A FROPA PASSAGE.
&&

.AVIATION...COLD FRONT ADVANCING THROUGH STATE TONIGHT WILL BRING
THUNDERSTORMS TO AREA THIS EVENING INTO OVERNIGHT HOURS. VFR
CONDITIONS BEHIND FRONT WED AFTERNOON.
&&

.HYDROLOGY...HIGH RAINFALL RATES AND RAINFALL AMOUNTS ON ONE TO
TWO INCHES AGAIN INCREASES RISK OF FLOODING.  SEE ESF.
