What happened

The episode as NWS DLH wrote it up.

Thunderstorms developed across northwest Wisconsin as a cold front moved through the region. The thunderstorms brought large hail. One of the hardest hit areas were within and near Hayward, WI and other parts of Sawyer County. There was a report of hailstones as large as 3 in diameter, or tea cup size, near New Post, WI. There were also reports of 2.5 diameter, or tennis ball size, hail in and near Hayward. There were nearly no reports of damaging winds with the storms, but one storm knocked over a tree onto a power line near Webster, WI.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Duluth, MN wrote its last area forecast discussion before the first event at Aug 2, 2:56 AM CST, 1 hour 9 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
356 AM CDT SUN AUG 2 2015

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 339 AM CDT SUN AUG 2 2015

AT 350 AM...STRONG THUNDERSTORMS CONTINUED ACROSS THE MINNESOTA
ARROWHEAD. WE HAVE SEEN SOME RAINFALL AMOUNTS OF AROUND A HALF
INCH...AT LITTLEFORK AND CRANE LAKE. THE STRONGEST STORM AT 340 AM
WAS MOVING THROUGH THE TIP OF THE ARROWHEAD...HEADING TOWARD THE
NEARSHORE WATERS OF WESTERN LAKE SUPERIOR. NEW STORMS HAD JUST
STARTED TO DEVELOP JUST EAST OF BRAINERD. TEMPERATURES WERE
GENERALLY IN THE 60S THIS MORNING.

THE FOCUS FOR TODAY WILL CONTINUE TO BE THUNDERSTORMS. THE MCS
CURRENTLY MOVING ACROSS NORTHERN MN SHOULD GRADUALLY PULL OFF TO
THE LAKE SUPERIOR REGION...BUT GUSTY WINDS WILL CONTINUE ACROSS
NORTHEASTERN MN. SPC MESOANALYSIS PARAMETERS INDICATE THE AREA
MOST RIPE FOR STRONG/SEVERE STORMS ACROSS THE SOUTHERN HALF TO 2/3
OF THE CWA...SO WILL NEED TO WATCH FOR FURTHER STRONG/SEVERE STORM
DEVELOPMENT ACROSS THAT AREA. THE GUST FRONT NOW PUSHING SOUTHWARD
FROM THE IRON RANGE WILL BE ONE FEATURE TO WATCH. MID LEVEL LAPSE
RATES ARE ON THE ORDER OF 7.5 FROM THE IRON RANGE SOUTHWARD AND
MOST UNSTABLE LI WERE -9 ACROSS THAT SAME AREA. THERE IS SOME
PRETTY IMPRESSIVE ELEVATED CAPE AS WELL.

TODAY...THE FOCUS WILL CONTINUE TO BE THUNDERSTORMS. THE FOCUS
FOR STORMS WILL SHIFT FROM NORTH TO SOUTH TODAY AS THE BEST
FORCING PUSHES SOUTH AND EAST. SPC HAS A SLIGHT RISK FOR MUCH OF
NW WI TODAY...WITH A MARGINAL FURTHER WESTWARD TOWARD BRAINERD AND
DULUTH. HIGH TEMPERATURES WILL RANGE FROM THE 70S NORTH TO 80 OR A
BIT HIGHER SOUTH.

FOR TONIGHT...THE FOCUS FOR STRONG/SEVER STORMS WILL BE IN NW WI
DURING THE EVENING...WITH SHOWERS AND THUNDERSTORMS ENDING ACROSS
THE AREA AS THE NIGHT WEARS ON. OVERNIGHT LOWS WILL RANGE FROM THE
40S TO 50S. SKIES WILL CLEAR FOR A TIME...BEFORE A STRATOCU DECK
PUSHES SOUTHWARD OUT OF CANADA.

MONDAY WILL BE COOLER ACROSS THE NORTHLAND...AS CLOUDS ARE
EXPECTED TO COVER MUCH OF THE CWA. HIGHS WILL RANGE FROM 60 TO 65
IN THE ARROWHEAD TO 70 TO 75 FURTHER SOUTH AND WEST. COULD BE SOME
SCATTERED SHOWERS AS WELL...MAINLY IN THE NORTHEAST HALF OF THE
CWA.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 339 AM CDT SUN AUG 2 2015

LITTLE CHANGE TO THE FORECAST OVERALL WITH COOLER TEMPERATURES AND
GENERALLY LOW CHANCES FOR PRECIPITATION THROUGH THE FIRST HALF OF
THE WEEK. SOME GUIDANCE COMING TOWARDS A CONSENSUS FOR LATE IN THE
WEEK BUT THERE STILL REMAINS CONSIDERABLE UNCERTAINTY INTO HOW THE
PATTERN WILL EVOLVE.

MON NIGHT THROUGH WEDNESDAY....MUCH COOLER TO START OFF THE WEEK
WITH A BROAD AREA OF HIGH PRESSURE OVER MANITOBA GRADUALLY BUILDING
SOUTH INTO THE UPPER MIDWEST. WITH A SERIES OF VORT MAXES ROTATING
AROUND A CLOUDS UPPER LOW IN EASTERN ONTARIO AND COLD AIR ADVECTING
IN ALOFT MAY SEE A FEW SHOWERS POPS UP ACROSS THE MINNESOTA
ARROWHEAD AS WELL AS PORTIONS OF THE SOUTH SHORE OF LAKE SUPERIOR.
AGREE WITH PREVIOUS FORECAST ASSESSMENT THAT THUNDERSTORMS DO NOT
APPEAR LIKELY...SO HAVE CONTINUED TO JUST INCLUDE SHOWERS IN THE WX
FORECAST. CHANCES WILL BE BEST MONDAY NIGHT INTO TUESDAY. ON
WEDNESDAY A WARM FRONT WILL LIFT NORTH TOWARDS THE REGION...MORE
DETAILS IN THE NEXT PARAGRAPH. TEMPS WILL BE SEASONABLE TO SLIGHTLY
BELOW NORMAL...HIGHS IN THE 60S TO LOW 70S...COOLEST ACROSS THE
MINNESOTA ARROWHEAD. HELD BACK FROM GOING BELOW THE MID 40S FOR LOWS
BECAUSE OF A CONCERN WITH CLOUD COVER...BUT IF SKIES ARE CLEAR COULD
SEE A FEW COLD SPOTS IN NORTHEAST MINNESOTA FALL TO THE LOW 40S OR
PERHAPS AN UPPER 30 OBSERVATION OR TWO.

THURSDAY THROUGH SATURDAY...MUCH LESS CONFIDENCE THROUGH THIS
PERIOD. WHILE THERE ARE CHANCES FOR PRECIP IN THE FORECAST FOR
NEARLY EVERY PERIOD...THIS DOES NOT SEEM LIKE A WASHOUT AT ALL. AT
UPPER LEVELS THE UPPER LOW OVER EASTERN ONTARIO MOVES NORTHEAST
WHILE A BROAD RIDGE OVER THE FOUR CORNERS REGION DRIFTS EASTWARD.
ALL GUIDANCE SUGGESTS A FEW MID-LEVEL SHORTWAVES MOVINGS EAST ACROSS
THE NORTHERN PLAINS IN BETWEEN THESE TWO FEATURES...BUT EACH HAS A
SLIGHTLY DIFFERENT TAKE. THE TREND SEEMS TO BE FOR A SHORTWAVE
TROUGH OVER THE EASTERN DAKOTAS BY LATE THURSDAY MOVING SOUTHEAST
INTO THE MID-MISSISSIPPI VALLEY. THIS WILL COINCIDE WITH A WARM
FRONT THAT WILL BE LIFTING NORTH INTO THE REGION...AT LEAST PER
ECMWF/GFS/GEFS. THE CANADIAN SOLUTION WHILE SIMILAR WITH REGARDS TO
FRONT POSITION DEPICTS DIFFERENT TIMING AND QPF...BUT IN GENERAL
GUIDANCE TONIGHT SEEMS TO BE IN BETTER AGREEMENT WITH CHANCES FOR
PRECIP HIGHEST THURSDAY ACROSS SOUTHERN PORTIONS OF THE CWA...BUT
SLIGHT CHANCES ABOUND GIVEN SPREAD IN SOLUTIONS. TEMPS SEASONABLE TO
SLIGHTLY BELOW NORMAL...WITH MILDER LOWS GIVEN EXPECTED CLOUD
COVER.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1235 AM CDT SUN AUG 2 2015

VFR CONDITIONS GENERALLY EXPECTED THROUGH THE TAF PERIOD WITH A
CHANCE FOR A BRIEF PERIOD OF MVFR VISIBILITY AND CEILING HEIGHTS
DUE TO ISOLATED STORMS OVERNIGHT OVER THE NEXT 6-12 HOURS.

OVERNIGHT/EARLY SUNDAY MORNING...A THUNDERSTORM COMPLEX IN
SOUTHERN MANITOBA IS MOVING SOUTHEAST INTO FAR NORTHWEST MINNESOTA
AND IS EXPECTED TO CONTINUE TO MOVE ACROSS NORTHEAST MINNESOTA
EARLY THIS MORNING. ELEVATED INSTABILITY SHOULD SUSTAIN THESE
STORMS...THE STRONGEST OF WHICH HAVE PRODUCED HAIL TO AT LEAST
QUARTER SIZE AND GUSTS IN EXCESS OF 60 MPH. COVERAGE OF STORMS
WILL BE FAIRLY ISOLATED THROUGH THE MORNING SO CHANCE OF IMPACT AT
ANY INDIVIDUAL SITE IS NOT VERY HIGH...EXCEPT FOR INL WHERE STORMS
ARE LIKELY TO IMPACT WITHIN THE NEXT FEW HOURS. USED TEMPO GROUPS
TO TIME THIS AREA OF STORMS AS IT PROGRESSES INTO THE MORNING
GIVEN EXPECTED COVERAGE. CEILINGS SHOULD REMAIN VFR...THOUGH HEAVY
RAINFALL COULD RESULT IN AN MVFR/IFR STRATUS DECK FORMING THIS
DOES NOT APPEAR LIKELY. VISIBILITY MAY BRIEFLY FALL TO MVFR IN THE
STRONGEST STORMS...BUT DURATION OF THIS OBSCURATION WOULD BE BRIEF
IF IT DOES OCCUR.

FOR THE DAY...GUSTY NORTHWEST WINDS EXPECTED AS SKIES PARTIALLY
CLEAR OUT OVER NORTHEAST MINNESOTA WHILE ISOLATED SHOWERS/STORMS
MAY PERSIST INTO NORTHWEST WISCONSIN. A FEW GUSTS TO THE 20-25KT
RANGE ARE EXPECTED AT MOST SITES THROUGH THE AFTERNOON...WITH
WINDS RAPIDLY DIMINISHING IN THE EVENING.
