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.

Area forecast discussion, Apr 10, 4:55 PM EDT, 3 hours 48 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
455 PM EDT SUN APR 10 2011

.SHORT TERM /TONIGHT THROUGH MONDAY/...

CONTINUE TO HAVE LIGHT SHOWER ACTIVITY ACROSS MUCH OF THE
AREA...WITH CONVECTION WELL TO THE SOUTH. THE MODERATE RISK FOR SVR
WEATHER REMAINS IN THE MOST FAVORABLE LOCATION...ALONG THE WI
BORDER. LOOK FOR THUNDERSTORMS TO INITIATE ACROSS WESTERN AND
CENTRAL WI NEAR 21Z...AND QUICKLY SLIDE ENE AT AROUND 40 PLUS KTS.
WILL CONTINUE THE SVR WORDING IN THE FORECAST...BUT TAPER IT A BIT
ON THE NORTHERN END. AFTERNOON HEATING HAS BEEN LIMITED ACROSS
CENTRAL AND EASTERN UPPER MI. STILL...TEMPS HAVE BEEN ABLE TO RISE
INTO THE 50S WITH DEW POINTS NOT TOO FAR BEHIND. THE WARM SPOTS
REMAIN OVER FAR WESTERN UPPER MI...WITH IWD AT 72F AT
1930Z...ASSISTED BY DOWNSLOPE WINDS. WILL WAIT TO SEE IF SOME OF THE
OTHER LOCATIONS DRY OUT...GIVEN THE SIGNIFICANT WEDGE OF WARM DRY
AIR JUST ABOVE THE SFC...WHICH LOOKS TO ERODE ACROSS MUCH OF OUR
SOUTHERN COUNTIES BY 00Z MONDAY.

THE SFC LOW IS NEAR MSP...AND WILL SHIFT NEAR IWD AT 00Z
MONDAY...WITH THE WARM FRONT SNEAKING INTO OUR SOUTHERN TIER
COUNTIES.  LARGE HAIL WILL BE THE MAIN THREAT AS THE VORT MAX NEARS
FROM SW IA. WITH THE FAST STORM MOTIONS...STRONG WINDS WILL ALSO BE
POSSIBLE...WITH THE CHANCE FOR TORNADOES REMAINING NEAR THE WI
BORDER AND A BETTER CHANCE SOUTH OF THE CWA. THE POTENTIAL
EXISTS...AS MENTIONED IN THE SPC DAY 1 OUTLOOK...OF A MCS SLIDING
OVER THE AREA LATE THIS EVENING. WENT ON A SLIGHTLY MORE OPTIMISTIC
SIDE...KEEPING THE BEST CHANCE FOR CONVECTION BETWEEN 00Z AND 06Z.
FZ LEVELS REMAIN AROUND 11KFT...WITH MU CAPE VALUES NEAR 1000 TO
OVER 2000J/KG NEAR IRON COUNTY. PW VALUES ARE AROUND 1IN THIS
AFTERNOON...AND GO UP TO JUST OVER 1.25IN JUST PRIOR TO 03Z...BEFORE
FALLING TO AROUND 0.6IN BY DAYBREAK MONDAY.

.LONG TERM...MONDAY NIGHT THROUGH SUNDAY

MON NIGHT INTO TUE...MID LEVEL SFC RIDGING BUILDING INTO THE UPPER
GREAT LAKES WILL BRING CLEARING SKIES AND DRY WEATHER. ENOUGH DRY AIR
SHOULD MOVE IN TO ALLOW TEMPS TO DROP INTO THE UPPER 20S TO AROUND
30 WITH FAVORABLE RADIATIONAL COOLING CONDITIONS OVERNIGHT. AS THE
HIGH SHIFTS TO THE EAST TUE...SW WINDS WILL INCREASE WITH WAA AND
850 MB TEMPS TO AROUND 4C ALLOWING INLAND TEMPS TO CLIMB INTO THE
UPPER 50S AND LOWER 60S WEST.

TUE NIGHT INTO THU... SHORTWAVE TROUGH AND SFC LOW MOVING FROM
MANITOBA THROUGH NRN ONTARIO WILL DRAG A COLD FRONT THROUGH LAKE
SUPERIOR AND UPPER MI. MODELS SUGGEST FGEN ALONG AND BEHIND THE
FRONT MAY SUPPORT A BAND OF LIGHT PCPN THAT WILL STEADILY ADVANCE
THROUGH THE CWA. HOWEVER...THE SYSTEM HAS TRENDED WEAKER WITH
DYNAMICS AND TOWARD LOWER QPF VALUES. SINCE THE STRONGER QVECTOR
CONV WITH THE SHRTWV REMAINS WELL TO THE NORTH...THE FCST KEEPS NO
MORE THAN CHANCE POPS THROUGH THE PERIOD. GFS/ECMWF WET-BULB ZERO
HEIGHTS INDICATE THAT ANY PCPN WOULD BE MAINLY RAIN.

FRI THROUGH SUN...THE GFS...GFS ENSEMBLE...ECMWF AND GEM HAVE
TRENDED FARTHER SOUTH WITH THE MID LEVEL/SFC LOW AND ASSOCIATED
DEFORMATION PCPN SHIELD TO THE NORTH. LOW LEVEL TEMPS/THICKNESSES
WOULD BE COLD ENOUGH FOR SNOW...POSSIBLY MIXED WITH RAIN IF THE PCPN
AREA DOES MAKE IT INTO UPPER MI. GIVEN THE AMOUNT OF
UNCERTAINTY...THE FCST STILL MAINTAINS CHANCE POPS THROUGH SAT.
&&

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

LIFR AND IFR CIGS WILL REMAIN AT SAW...WITH ONLY SLIGHT IMPROVEMENT
TO MVFR THIS AFTERNOON AS DAYTIME HEATING SCOURS OUT SOME OF THE
LINGERING LOW LEVEL MOISTURE. SHOWERS AND POSSIBLY TS WILL RETURN
AFTER 02Z.

AT CMX LIFR CONDITIONS HAVE IMPROVED AS WINDS TURNED MORE SOUTHERLY
LATE THIS MORNING. LOOK FOR LIFR TO IFR CONDITIONS TO RETURN TOWARDS
02Z WITH THE ADVANCE OF SHRA AND THE POSSIBILITY OF TS. HAVE KEPT CB
IN THE FORECAST UNTIL 06Z...AND WILL AMEND TO ADD TS IF IT BECOMES
MORE LIKELY.

CEIGS AND VIS WILL REBOUND TO OR NEAR MVFR BY LATE MORNING
MONDAY...AS THE BULK OF MOISTURE EXITS TO THE NE. HOWEVER THIS LAST
ROUND OF SHOWERS MAY LINGER INTO EARLY AFTERNOON AT SAW. LOOK FOR
STRONGER WINDS ALOFT /LLWS AFTER 06Z/ TO MIX DOWN TO THE SFC PRIOR
TO DAYBREAK MONDAY...WITH GUSTY WNW WINDS NEAR 35KTS THROUGH MUCH OF
THE AFTERNOON HOURS.
&&

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

LOW PRESSURE JUST SOUTHWEST OF LS WILL SLIDE ACROSS AND JUST
NORTHEAST OF LS BY DAYBREAK MONDAY. AFTER THE EXIT OF THE
LOW...STRONGER N WINDS NEARING GALES TO 40KTS WILL DEVELOP MONDAY
ACROSS MAINLY CENTRAL AND EASTERN LS. A RIDGE WILL SWING WEST TO
EAST ACROSS THE UPPER GREAT LAKES LAKES MONDAY AFTERNOON THROUGH THE
DAY TUESDAY...WITH WINDS RELAXING TO LESS THAN 20KTS LATE MONDAY
NIGHT. A TROUGH OVER MINNESOTA TUESDAY NIGHT WILL PUSH SOUTHEAST
OVER LS WEDNESDAY...BEFORE SLOWLY SETTLING ACROSS LM AND LH FROM
WEDNESDAY NIGHT THROUGH THE END OF THE WORK WEEK. IN THE
MEANTIME...HIGH PRESSURE TRACKING FROM MANITOBA TO CENTRAL ONTARIO
FROM WEDNESDAY THROUGH FRIDAY WILL BRING A RIDGE ACROSS LS WEDNESDAY
NIGHT THROUGH FRIDAY MORNING. BY FRIDAY AFTERNOON LOW PRESSURE OVER
THE MID MISSISSIPPI VALLEY SHOULD LIFT A TROUGH OVER LS.
&&

.HYDROLOGY /UPDATED AT 18Z/...

24 HOUR PRECIP REPORTS OF 0.15 TO 1.15 INCHES HAVE COME IN FROM THE
INITIAL ROUND OF SHOWERS AND THUNDERSTORMS. THE LOWEST AMOUNTS WERE
ACROSS THE KEWEENAW PENINSULA...WITH THE HIGHEST OVER CENTRAL UPPER
MI...EAST OF A LINE FROM BIG BAY TO GLADSTONE. AS FOR HYDROLOGIC
ISSUES...LEVEL OF CONCERN WILL LARGELY DEPEND ON THE TRACKS OF THE
THUNDERSTORMS THIS AFTERNOON AND EVENING. THE ABOVE NORMAL TEMPS HAVE
REALLY DIMINISHED THE SNOWPACK ACROSS THE AREA...WITH THE REMAINING
SNOW LARGELY OCCURRING OVER THE HIGHER TERRAIN AND WOODED LOCATIONS.
THIS HAS CAUSED AREA RIVERS TO BEING TO RISE TOWARDS ACTION STAGES AT
SOME LOCATIONS /PARTICULARLY ALSTON AND CRYSTAL FALLS/. WOULD NOT BE
SURPRISED TO SEE SOME LOCATIONS NEARING FLOOD STAGE OVER THE NEXT
COUPLE OF DAYS. RESIDENTS LIVING ALONG RIVERS IN UPPER MICHIGAN
SHOULD REMAIN ALERT FOR RISING WATERS AND EXERCISE CAUTION WHEN
WALKING NEAR RIVERBANKS OVER THE NEXT WEEK.
