What was reported inside it

Time	Report	Where	Remark
Jun 18, 6:38 PM CDT	HAIL 0.5	New Holstein, 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 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 watch it was issued in

Area forecast discussion, Jun 18, 2:55 PM CDT, 3 hours 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
255 PM CDT MON JUN 18 2012

.SYNOPSIS..VERY ACTIVE WEATHER WITH SEVERAL ROUNDS OF
THUNDERSTORMS THE NEXT COUPLE DAYS...WITH SOME POSSIBLY SEVERE.

BROAD UPR TROF OVER MUCH OF THE NRN CONUS WL AMPLIFY THE NEXT
COUPLE DAYS AS MAJOR SHRTWV ROTATES THROUGH THE LARGE SCALE TROF
AND OUT TO THE NE. BEYOND THAT...PATTERN WL TREND TOWARD ONE WITH
BROAD UPR HIGH ANCHORED OVER THE CENTRAL PLAINS AND RIDGING NWD
ACRS THE NRN PLAINS/PRAIRIE PROVINCES OF CANADA...WITH TROFS NEAR
THE WEST COAST AND OVER THE NERN CONUS.

TEMPS WL BE SIG ABV NORMAL FOR THE NEXT COUPLE DAYS...AND NOW THAT
WIDESPREAD RAINFALL HAS OCCURRED ACRS THE AREA IT WL BE HUMID AS
WELL. TEMPS WL TREND BACK CLOSER TO NORMAL AND DRIER AIR WL SETTLE
INTO THE FCST AREA BY THE UPCOMING WEEKEND. PCPN AMNTS WL LIKELY
END UP ABV NORMAL FOR THE PERIOD...MAINLY DUE TO THE SEVERAL
ROUNDS OF TSTMS EXPECTED THE NEXT COUPLE DAYS. ALTHOUGH PCPN CHCS
WL CONT ON INTO THE MIDDLE TO LATTER PART OF THE FCST...THE
PATTERN DOESN/T APPEAR AS FAVORABLE FOR HVY PCPN BY THAT POINT.
&&

.SHORT TERM...TNGT/TUE. CONCERN IS ONGOING CONVECTION. EXPECT
CELLS WITHIN LINE TO CONGEAL DURING THE NEXT COUPLE HOURS...THEN
SAG/BUILD SWD. AS THAT HAPPENS...THE MAIN THREAT WL CHG FM HAIL TO
WIND. WILL ALSO SEE AN INCREASED THREAT OF HEAVY RAIN/URBAN
FLOODING AS THE COVERAGE INCREASES.

QUESTIONS EXIST ABOUT THE EVOLUTION OF THE CONVECTION LATER TNGT.
SOME INDICATION THAT WSW/ENE LINE WL LINGER ACRS THE AREA WELL
INTO THE NGT...WITH AN INCREASED RISK OF FLOODING. CONSIDERED A
FLASH FLOOD WATCH...BUT GIVEN DRY CONDITIONS RECENTLY RIVERS WL BE
ABLE TO TAKE A LOT OF WATER. NEED TO SEE HOW SITN EVOLVES THE NEXT
FEW HOURS...CAN ALWAYS ISSUE LATER IF NEEDED.

FRONT/REMNAMTS OF OUTFLOW SHOULD LIFT NWD TOMORROW. HOT/HUMID
CONDITONS WL SPREAD NWD ACRS THE FCST AREA IN IT/S WAKE. SHIFTED
POPS NWD DURING THE DAY.

.LONG TERM...WED NGT THROUGH NEXT TUE. KEY TO THE EARLY PART OF
THIS FCST PERIOD WL BE THE MOVEMENT OF THE FRONTAL BOUNDARY. USED
BLEND OF GUID TO PLACE POPS.

MED RANGE MODELS TRENDED TOWARD WHAT ECMWF HAD YDA...WITH MAIN
FRONT GETTING DRIVEN WELL S IN LATER PERIODS. SO ALTHOUGH PCPN
CHCS WL CONT AT TIMES...THE THREAT OF HEAVY PCPN WON/T BE AS
GREAT. TEMPS WL ALSO RETURN BACK CLSOER TO TO NORMAL.

.AVIATION...FOR 18Z TAF ISSUANCE. A COOL FRONT WILL DROP ACROSS
NORTHERN WISCONSIN TODAY BEFORE STALLING ACROSS CENTRAL WISCONSIN
TONIGHT...THEN LIFTING BACK NORTH ON TUESDAY. SHOWERS AND STORMS
ARE EXPECTED TO REDEVELOP THIS AFTERNOON ALONG THIS BOUNDARY. SOME
STORMS MAY TURN SEVERE WITH STRONG GUSTY WINDS AND LARGE HAIL AS
THE MAIN THREATS. MVFR STRATO-CU CIGS WILL LIKELY REMAIN IN PLACE
ACROSS MOST OF THE TAF SITES THIS AFTERNOON AND THEN SINK SOUTH
WITH THE FRONT. STORMS WILL LIKELY DISSIPATE WITH LOSS OF HEATING
BY MID-EVENING AND THEN RE-FIRE OVER MINNESOTA TONIGHT. SOME
STORMS FROM MINNESOTA MAY TRY TO MOVE INTO CENTRAL AND NORTH-
CENTRAL WISCONSIN LATE TONIGHT INTO TUESDAY MORNING.
&&

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