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.

The nearest sounding before it

Detroit, MI (KDTX), launched 00:00Z, 6.7 hours before the alert went out and 107 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1115 PM EDT TUE JUN 7 2005

.UPDATE...
LATEST SFC ANALYSIS THIS EVENING REVEALS THE NEARLY STATIONARY
FRONTAL SYSTEM EXTENDING FROM SRN MN EASTWARD ACROSS CENTRAL/NRN
LOWER MI. LATEST REGIONAL RADAR IMAGERY THIS EVENING SHOWS THE BKN
LINE OF CONVECTION THAT DEVELOPED EARLIER OVER WI HAS NOW BECOME A
SOLID LINE OF CONVECTION JUST NORTH OF THIS SFC BOUNDARY. THIS
CONVECTION IS SHOWING A MOVEMENT TO THE ENE. THIS MOVEMENT WOULD BE
EXPECTED AS THE WAVE HELPING TO FIRE THE CONVECTION RIDES ALONG THE
FRONT. 850-300 MB THICKNESSES ALSO SUPPORT THE ENE MOVEMENT THROUGH
THE NIGHT. WITH THE ENE MOVEMENT...THIS LINE OF CONVECTION WOULD
LIKELY JUST MISS OUR ENTIRE CWFA TO THE NORTH. WITH THIS IN MIND AND
IN COLLABORATION WITH SURROUNDING OFFICES...WE HAVE DROPPED POPS
OVER THE NRN SECTION OF THE CWFA TO 40 PCT.

ELSEWHERE ACROSS THE CWFA...DRY CONDITIONS ARE CURRENTLY IN PLACE.
EARLIER SFC BASED CONVECTION THAT TRIED TO MOVE ACROSS THE LAKE FROM
WI FIZZLED OUT BEFORE IT MADE IT TO THE ERN SHORELINE OF LAKE
MICHIGAN. IT IS EXPECTED THAT MOST OF THE CWFA SHOULD REMAIN
RELATIVELY QUIET THROUGH THE NIGHT WITH ALL OF THE ACTION REMAINING
JUST NORTH AND WELL WEST OF THE CWFA. THE EXCEPTION TO THIS WOULD BE
A RIBBON OF HIGHER DEW POINTS ALOFT THAT IS CURRENTLY ADVECTING IN
FROM THE WSW. WITH THIS RIBBON OF HIGHER DEW POINTS ADVECTING
IN...ELEVATED LI/S FALL TO AS LOW AS -6 LATE TONIGHT. WITH THIS
ADVECTION OF HIGHER MOISTURE...A FEW SHOWERS AND THUNDERSTORMS CAN
NOT BE RULED OUT. THEREFORE WE HAVE LEFT THE 30 PCT CHC OF SHOWERS
AND STORMS IN FOR THE REMAINDER OF THE CWFA. MOST AREAS SHOULD
REMAIN MAINLY DRY TONIGHT.

DEW POINTS AT THE SFC ARE MAINLY IN THE 60S AT THIS HOUR WITH A FEW
ISOLATED DEW POINTS IN THE UPPER 50S. WITH THESE HIGHER DEW
POINTS...TEMPS WILL ONCE AGAIN REMAIN MILD TONIGHT WITH LOWS
EXPECTED TO ONLY FALL INTO THE 60S ACROSS THE AREA.

.GRR WATCHES/WARNINGS/ADVISORIES...NONE.
