Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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 6, 8:00 AM EDT, 3 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
800 AM EDT TUE APR 6 2010

LATEST UPDATE...AVIATION...

.SYNOPSIS...(515 AM EDT TUE APR 6 2010)
MORE THUNDERSTORM DEVELOPMENT IS EXPECTED LATE THIS MORNING AND
THIS AFTERNOON AND EVENING ALONG AND AHEAD OF A WARM FRONT THAT WILL
CUT ACROSS THE CWA. TEMPERATURES WILL REACH INTO THE 70S SOUTH OF
THE FRONT WHILE COOLER TEMPS IN THE 50S AND 60S WILL BE FOUND NORTH.
SEVERE WEATHER IS POSSIBLE TODAY.

&&

.SHORT TERM...(515 AM EDT TUE APR 5 2010)
(TODAY THROUGH THURSDAY)

WHILE WE WILL ENTER INTO A BIT OF A LULL THIS MORNING...THE WARM
FRONT LIFTING INTO OUR CWA WILL POSE A HEIGHTENED RISK FOR SEVERE
WEATHER TODAY.

BOTH THE NAM AND GFS ARE SHOWING THE WARM FRONT REACHING THE I-96
REGION BY MID AFTERNOON. ALONG AND IMMEDIATELY AHEAD OF THE
FRONT...THE ENVIRONMENT WILL BE SUPPORTIVE OF STRONG TO SEVERE
THUNDERSTORMS. ML COMPUTED CAPE OF 500-1000 J/KG...ALONG WITH SFC
VORT IN ASSOCIATION WITH THE FRONT AND GOOD 0-1 KM SRH ARE CAUSE FOR
CONCERN. ALL SEVERE WEATHER THREATS ARE ON THE TABLE THIS AFTERNOON
AND EVENING...INCLUDING ISOLATED TORNADOES. LOWER LCLS OF 1000-2000
FT ARE FORECAST TO OCCUR ALONG THE FRONT AS WELL.

MTVS ARE POINTED AT THE CWA DURING THE AFTERNOON/EVENING AND
MOISTURE FLUX CONV WILL BE PRESENT AS THE CONVECTION RE-FIRES. PWATS
MAY REACH 1.3-1.4 INCHES IN SOME LOCATIONS. ANY THUNDERSTORMS WILL
HAVE THE POTENTIAL TO PRODUCE HEAVY RAINFALL.

THE SFC LOW WILL BE CROSSING THE SOUTHERN GREAT LAKES LATER
WEDNESDAY AND PRECIPITATION SHOULD BE WINDING DOWN BY LATE WED/EARLY
THU. CHILLY TEMPERATURES ARE ANTICIPATED THURSDAY WITH HIGHS
STRUGGLING TO REACH THE UPPER 40S/NEAR 50.

&&

.LONG TERM...(415 AM EDT MON APR 5 2010)
(THURSDAY NIGHT THROUGH MONDAY)

THE COOLER WEATHER CONTINUING INTO FRIDAY IS BRIEF AS PROGRESSIVE
PATTERN ALOFT RESULTS IN THE H5 TROUGH OVER THE REGION BEING BOOTED
OUT BY 12Z SATURDAY. A RISK OF FROST AND/OR FREEZING TEMPERATURES
STILL EXISTS FOR THURSDAY NIGHT AND FRIDAY NIGHT DEPENDING ON EXTENT
OF CLEARING AND WIND SPEEDS. VEGETATION IS WAY AHEAD OF SCHEDULE
THIS YEAR SO ALTHOUGH NOT UNUSUAL TO GET A FREEZE IN EARLY APRIL IT
IS SOMETHING THAT FARMERS AND GARDENERS ARE PROBABLY VERY CONCERNED
ABOUT.

DIGGING LONGWAVE TROUGH OVER THE WRN UNITED STATES LEADS TO RISING
HEIGHTS OVER THE ERN HALF OF THE NATION THIS WEEKEND AND AN EVENTUAL
RENEWAL OF UPPER LEVEL RIDGING. THUS ANOTHER WARM UP LOOKS TO BE IN
STORE BEGINNING SATURDAY AND HAVE NUDGED UP TEMPS ACCORDINGLY. HAVE
KEPT THINGS DRY THROUGH MONDAY AS IT APPEARS NO APPRECIABLE RETURN
FLOW DEVELOPS UNTIL MID WEEK.

&&

.AVIATION...(800 AM EDT TUE APR 6 2010)
NEXT CLUSTER OF SHWRS AND TSTMS WAS APPROACHING FROM THE WEST AND
SHOULD ARRIVE AT MKG AROUND 13Z AND LAN/JXN AROUND 15Z. THIS WILL
PROBABLY BE A QUICK-HITTER OF ONLY AN HOUR OR TWO OF THUNDER ALONG
THE I-94 CORRIDOR.... WITH THE WARM FRONT PUSHING JUST NORTH OF
THERE TOWARD 18Z. CONDITIONS WILL LIKELY BECOME VFR WITH SOUTH WINDS
BECOMING GUSTY 15-25 KNOTS ONCE THE WARM FRONT PUSHES NORTH THIS
AFTERNOON. THEN NEXT CHC OF THUNDER FOR I-94 CORRIDOR PROBABLY NOT
TIL AFTER 06Z TONIGHT.

VERY DIFFICULT/LOW CONFIDENCE FCST FOR THE I-96 CORRIDOR. THIS ROUND
OF CONVECTION APPROACHING FROM THE WEST WILL PROBABLY LINGER LONGER
THAN FOR THE I-94 CORRIDOR AREA AND PREVENT MUCH OF A NWD SURGE OF
THE WARM FRONT... SO BELIEVE THE FRONT WILL NOT MAKE IT MUCH FARTHER
NORTH I-96. WILL THEREFORE KEEP MKG/GRR/LAN IFR MOST OF THE TAF
PERIOD WITH LINGERING SHOWERS/LGT FOG AFTER THE THUNDER THREAT
DIMINISHES LATER THIS MORNING.

&&

.MARINE...(415 AM EDT TUE APR 6 2010)
SHOWERS AND STORMS WILL POSE A THREAT TO MARINERS THROUGH WEDNESDAY.
THE GREATEST WAVE HEIGHTS WILL COME WEDNESDAY AND WEDNESDAY
NIGHT...WITH 2 TO 4 FOOTERS POSSIBLE.

&&

.HYDROLOGY...(415 AM EDT TUE APR 6 2010)
RIVER RISES ARE EXPECTED OVER THE NEXT COUPLE DAYS AS SIGNIFICANT
RAINFALL ON THE ORDER OF 1 TO 2 INCHES THROUGH LATE WEDNESDAY IS
ANTICIPATED. LOCALIZED FLASH FLOODING IS POSSIBLE IN THE STRONGEST
STORMS ON TUESDAY.

&&

.FIRE WEATHER...(415 AM EDT TUE APR 6 2010)
GIVEN THE EXPECTED RAINFALL...LITTLE IF ANY FIRE WEATHER THREAT IS
PRESENT FOR THE ENTIRE GRR CWA. CONDITIONS WILL NOT DRY OUT UNTIL
THURSDAY.

&&
