The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Marquette, MI wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 12:59 PM CDT, 3 hours 15 minutes earlier.

Area forecast discussion, May 22, 12:59 PM CDT, 3 hours 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
159 PM EDT SUN MAY 22 2011

UPDATED AVIATION DISCUSSION FOR 18Z TAFS

.DISCUSSION...

UPPER AIR PATTERN CONSISTS OF A CLOSED 500 MB LOW OVER SD WITH
ANOTHER CLOSED LOW OFF NEW ENGLAND WITH A RIDGE OVER THE LOWER GREAT
LAKES. THE CLOSED LOW OVER SD WITH IT ASSOCIATED TROUGH WILL HEAD
SLOWLY EAST AND BE ACROSS THE U.P. ON MON.

NAM SHOWS SOME 850-500 MB Q-VECTOR CONVERGENCE WITH SOME DEEPER
MOISTURE LASTING INTO MON WITH SOME STRONGER DYNAMICS ARRIVING SUN
NIGHT. GFS SHOWS ABOUT THE SAME THING AS WELL.

COMPLICATED FORECAST FOR TODAY AS CONVECTION LOOKS TO MOVE IN THIS
MORNING AS STUFF HAS BROKEN OUT ACROSS CENTRAL WISCONSIN AND IS
HEADING NORTH. THIS SHOULD MAKE IT INTO THE WESTERN CWA THIS
MORNING. SHOWERS ASSOCIATED WITH THE ISENTROPIC LIFT LAST EVENING
ARE MOVING OUT OF THE EASTERN CWA AND THE CONVECTION WILL BEGIN TO
MOVE IN AS THE DYNAMICS MOVE EAST TODAY. QUESTION IS HOW MUCH
SUNSHINE WILL BE SEEN TO ALLOW HEATING TO TAKE PLACE. WITH
CONVECTION COMING IN WAVES...NOT SURE HOW WARM IT WILL GET TODAY.
KEPT TEMPERATURES THE SAME FOR TODAY AS ANY SUNSHINE WILL ALLOW IT
TO WARM UP RAPIDLY. STILL THINK IT WILL BE MOSTLY CLOUDY WITH A FEW
PEAKS OF SUNSHINE. NOT SURE HOW MUCH OF A SEVERE WEATHER THREAT
THERE WILL BE EITHER AS CONVECTION THIS MORNING MIGHT NOT ALLOW
ATMOSPHERE TO RECHARGE OVER OUR AREA TODAY AS WELL. THE SLIGHT RISK
OVER THE SOUTH HALF OF THE CWA DOES APPEAR TO BE WARRANTED AS THEY
WILL BE CLOSER TO THE MOST UNSTABLE AIR AND HAIL AND WIND WOULD BE
THE THREATS AS WET BULB ZERO HEIGHTS GET LOWER THIS AFTERNOON TO
9000 FEET. -20C LINE IS ABOUT 20000 FEET AS WELL AS FORECAST BY THE
NAM.

COLD AIR LOOKS TO BE DELAYED ON MONDAY AS MODELS ARE SHOWING IT
COMING IN LATE IN THE AFTERNOON AS 850 MB TEMPERATURES FALL...SO
WARMED TEMPERATURES UP A BIT FOR MONDAY. TUE NIGHT LOOKS TO BE THE
COLDEST NIGHT WITH LIGHT WINDS AND RADIATIONAL COOLING SET UP
ALLOWING TEMPERATURES TO DROP BELOW FREEZING IN A FEW PLACES AND
WILL PROBABLY NEED SOME FROST/FREEZE HEADLINES AT THAT POINT. ONE
OTHER MAJOR CHANGE I DID TO THE FORECAST IS THE MODELS ARE GOING DRY
INTO SATURDAY AND TOOK ALL PCPN OUT OF THE FORECAST AND DECREASED
THE CLOUD COVER. THERE ALSO LOOKS TO BE A SECONDARY SURGE OF COLD
AIR ON THU INTO FRI AND LOWERED GOING HIGHS A FEW DEGREES FOR THU
THROUGH FRI AS BOTH THE GFS AND ECMWF SHOW COLDER AIR COMING IN WITH
850 MB TEMPERATURES DROPPING TO 0C ON THU. WILL PROBABLY HAVE TO
WORRY ABOUT SOME MORE FROST FOR THU NIGHT AS A FEW PLACES COULD
AGAIN GET BELOW FREEZING WITH CLEAR SKIES AND LIGHT WINDS ALLOWING
GOOD RADIATIONAL COOLING TO AGAIN SET UP. THESE ARE THE MAJOR
CHANGES I MADE TO THE GOING FORECAST. OTHERWISE...MINOR CHANGES TO
TEMPERATURES WITH A FEW TWEAKS HERE AND THERE.
&&

.AVIATION /FOR THE 18Z TAF ISSUANCE/...

A LOW PRESSURE SYSTEM OVER SOUTHWEST MN WILL MOVE OVER THE AREA
MONDAY MORNING. THUNDERSTORMS ASSOCIATED WITH THIS SYSTEM WILL MOVE
INTO THE AREA THIS EVENING...WITH THE EXACT TIMING/EXTENT OF THE
THUNDERSTORMS BEING UNCERTAIN.

SCATTERED CUMULUS DECK WILL RESULT FROM SURFACE HEATING AS SUN
BREAKS THIS AFTERNOON AND EVENING. LIFR CONDITIONS WILL MOVE IN
BEHIND THE RAIN TONIGHT. WINDS WILL SHIFT MORE OUT OF THE WEST LATE
IN THE TAF PERIOD...BRINGING LOWER CIGS/VIS AT CMX WHERE WINDS WILL
BE OFF THE LAKE.
&&

.MARINE /FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE/...

EAST TO SOUTHEAST WINDS OF 10-20KT...OCCASIONALLY AS HIGH AS 25KT...
WILL DOMINATE LAKE SUPERIOR TODAY AND TONIGHT AS LOW PRES OVER THE
DAKOTAS MOVES E TOWARD LAKE SUPERIOR. AS IS TYPICAL...WINDS WILL BE
BACKED MORE TO THE NORTHEAST OVER THE WRN PORTION OF THE LAKE. AS
THE LOW MOVES E OF LAKE SUPERIOR LATE MON AFTN...A SURGE OF STRONGER
NRLY WINDS OF 20-30KT WILL DEVELOP FROM NCNTRL LAKE SUPERIOR TO
SCNTRL AND SE LAKE SUPERIOR. ALTHOUGH INCOMING AIRMASS BEHIND LOW
WON'T BE COLD ENOUGH TO SUPPORT DEEP MIXING DUE TO THE COLD MARINE
LAYER...CAA AND DECENT PRES RISE MAY SUPPORT SOME GALE FORCE GUSTS
AT HIGHER OBSERVING PLATFORMS MON AFTN AND EARLY EVENING. WITH SFC
HIGH PRES GENERALLY DOMINATING THE UPPER LAKES TUE THRU THU...
TYPICAL WARM SEASON LAKE BREEZE CIRCULATIONS WILL BE THE RULE DAILY
WITH THE END RESULT BEING WINDS MOSTLY UNDER 20KT.

AS FOR FOG...SHIP OBS CONTINUE TO SHOW AT LEAST SOME AREAS OF DENSE
MARINE FOG OVER LAKE SUPERIOR. OPTED TO MAINTAIN GOING DENSE FOG
HEADLINES. VIS SATELLITE IMAGERY TODAY MAY YIELD A BETTER LOOK AT
FOG COVERAGE...BUT CLOUD COVER MAY OBSCURE A GOOD LOOK FOR MUCH OF
THE DAY. IN ANY EVENT...FOG SHOULD CONTINUE TO PLAGUE LAKE SUPERIOR
UNTIL MON AFTN/EVENING WHEN STRENGTHENING NRLY WINDS BRING DRIER AIR
INTO THE AREA BEHIND LOW PRES.
