What was reported inside it

Time	Report	Where	Remark

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.

529 PM CDT FRI MAY 31 2013

UPDATED AVIATION PORTION FOR 00Z TAF ISSUANCE

.SHORT TERM...TONIGHT AND SATURDAY
ISSUED AT 233 PM CDT FRI MAY 31 2013

SEVERE THUNDERSTORM WATCH NOW IN EFFECT UNTIL 10 PM FOR LOCATION
WEST AND NORTHWEST OF THE FOX VALLEY.

TEMPERATURES THIS AFTERNOON WERE IN THE 70S TO NEAR 80 WITH DEW POINTS
IN THE MIDDLE 50S NORTH TO THE LOWER TO MIDDLE 60S SOUTH. CONVECTION
DEVELOPED ACROSS MINNESOTA AND WESTERN WISCONSIN DURING THE PAST
HOUR. MODIFIED SOUNDINGS USING A CONSERVATIVE TEMP/DEW POINT OF
78/62 GAVE ME OVER 1500 J/KG OF CAPE. SPEED MAX EXPECTED TO CROSS
THE AREA LATER THIS AFTERNOON TO ENHANCE LIFT. MORE PROBLEMATIC IS
THE STEEP MID LEVEL LAPSE RATES AROUND 7-7.5 C/KM AND 0-6 KM SHEAR
OF 50 TO 70 KNOTS. A QUICK GLANCE AT SOME OF THE TORNADO PARAMETERS
WOULD SUGGEST THAT TORNADOES WOULD BE POSSIBLE ACROSS PORTIONS OF
CENTRAL AND NORTHEAST WISCONSIN. SHOWERS AND THUNDERSTORMS WILL
DIMINISH FROM WEST TO EAST LATER THIS EVENING AND OVERNIGHT.

UPPER TROUGH WILL SWING ACROSS THE AREA ON SATURDAY...BRINGING
INCREASING CHANCES FOR SHOWERS AND SOME THUNDERSTORMS AS THE DAY
WEARS ON. HIGHS WILL RANGE FROM THE MIDDLE TO UPPER 60S FAR NORTH
TO THE MIDDLE AND UPPER 70S SOUTH.

ISSUED AT 233 PM CDT FRI MAY 31 2013

THE MAIN FCST CONCERNS INCLUDE PCPN TRENDS FOR THE END OF THE WEEKEND...
COOLER AND DRIER WEATHER AND FROST POTENTIAL FOR THE BEGINNING OF
THE WORK WEEK...AND INCREASING PCPN CHANCES AGAIN BY MIDWEEK.

A COLD FRONT WILL WORK ITS WAY THOUGH GRB CWA ON SATURDAY NIGHT...AS
AN UPPER LEVEL TROF MOVES THROUGH THE REGION. WILL CONTINUE TO MENTION
MID-RANGE CHANCE POPS OVER OUR SOUTHERN COUNTIES...AND LIKELY POPS
OVER THE NORTH...WHERE THE BEST LIFT AND SATURATION WILL OCCUR.
SOME LINGERING LIGHT SHOWERS ARE POSSIBLE INTO SUNDAY MORNING...BUT
DRY CONDITIONS AND DECREASING CLOUDS ARE ANTICIPATED BY AFTERNOON.

CANADIAN HIGH PRESSURE WILL BRING MOSTLY CLEAR SKIES SUNDAY NIGHT
INTO TUESDAY. EXPECT MIN TEMPS TO DROP INTO THE LOWER TO MIDDLE
30S ACROSS NORTH CENTRAL AND FAR NORTHEAST WI SUNDAY NIGHT AND
MONDAY NIGHT...LEADING TO FROSTY CONDITIONS THERE. WILL LIKELY
NEED FROST ADVISORIES OVER NORTHERN WI.

AS THE SFC HIGH SHIFTS EAST...PCPN CHANCES WILL INCREASE AGAIN INTO
MIDWEEK...AND LINGER INTO AT LEAST THURSDAY NIGHT. SOME THUNDER IS
POSSIBLE...ESPECIALLY FROM WEDNESDAY NIGHT INTO THURSDAY EVENING.

COOL TEMPERATURES...WITH HIGHS IN THE 60S...ARE EXPECTED FOR MOST
OF THE PERIOD...ALTHOUGH A SLIGHT MODERATING TREND MAY BRING
READINGS CLOSE TO NORMAL BY THE END OF THE NEXT WORK WEEK.

BE STRONG OR SEVERE THIS EVENING WITH DAMAGING WINDS...LARGE HAIL AND
VERY HEAVY RAIN. GUSTS OVER 50 KNOTS AND HAIL OVER 1 INCH ARE
POSSIBLE IN THE STRONGEST STORMS. ANY THUNDERSTORMS COULD PRODUCE
VERY HEAVY RAIN WITH VISIBILITIES BELOW ONE MILE...AND AT TIMES
COULD BE DOWN TO 1/4 TO 1/2 MILE IN THE HEAVIEST STORMS. SHOWERS
AND STORMS WILL BE ON THE WANE LATER THIS EVENING AND OVERNIGHT.
THERE WILL BE A LULL IN THE PRECIPITATION LATE TONIGHT/EARLY
SATURDAY MORNING BEFORE SHOWERS AND STORMS WILL BECOME MORE NUMEROUS
AGAIN SATURDAY AFTERNOON AS UPPER TROUGH APPROACHES FROM THE WEST.

WEB CAMS AND SATELLITE IMAGES CONTINUE TO SHOW DENSE FOG
ACROSS MUCH OF LAKE MICHIGAN AND ACROSS OUR NEAR SHORE WATERS.
DENSE MARINE FOG WILL CONTINUE THROUGH SATURDAY MORNING...AND
POSSIBLY INTO EARLY SATURDAY EVENING. THE DENSE FOG COULD LIFT FOR
A PERIOD OF TIME TONIGHT DUE TO TURBULENT MIXING IN AND NEAR
THUNDERSTORMS. SHOWERS AND THUNDERSTORMS ACROSS MINNESOTA AND
WESTERN WISCONSIN WILL WORK ACROSS THE AREA LATE THIS AFTERNOON
AND EVENING. THERE IS A CHANCE OF SHOWERS AND POSSIBLY A
