The episode as NWS GRR wrote it up.
Severe thunderstorms developed during the late afternoon and evening hours of April 26 as an upper level trough and cold front approached our region. Several low topped supercells developed and produced numerous reports of large hail up to around two inches in diameter. In addition a damage survey team from the NWS Grand Rapids office determined that damage caused near Burnips in Allegan County was due to an EF-0 tornado with top winds near 85 mph that damaged buildings at the Deboer Turkey Farm and trailers around the area. In Portage, nine people were injured by a lightning strike.
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 Grand Rapids, MI wrote its last area forecast discussion before the first event at Apr 26, 3:00 PM EST, 29 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 400 PM EDT TUE APR 26 2011 LATEST UPDATE...ALL BUT AVIATION... .SYNOPSIS...(400 PM EDT TUE APR 26 2011) AN ACTIVE PATTERN WILL CONTINUE. THE THREAT FOR SEVERE WEATHER THIS EVENING WILL GIVE WAY TO A PROLONGED PERIOD OF RAIN WEDNESDAY MORNING THOUGH THURSDAY. RIVER FLOODING WILL BECOME MORE OF A CONCERN BY THE END OF THE WORK WEEK. TEMPERATURES WILL BE MILD WEDNESDAY WITH HIGHS MAINLY IN THE 60S...BUT THEN IT WILL COOL OFF BY THURSDAY WITH HIGHS ONLY FROM 45 TO 50. THE EARLY PART OF THIS COMING WEEKEND LOOKS DRY WITH INCREASING RAIN CHANCES BEGINNING SUNDAY. && .SHORT TERM...(400 PM EDT TUE APR 26 2011) MAIN CONCERNS ARE SEVERE CONVECTIVE THREAT THROUGH THIS EVENING... FOLLOWED BY HEAVY RAIN AND AREAL FLOODING POTENTIAL THROUGH THURSDAY. WE WILL ISSUE A FLOOD WATCH FOR OUR ENTIRE CWA FROM WEDNESDAY MORNING UNTIL THURSDAY EVENING. A TORNADO WATCH IS IN EFFECT UNTIL 10 PM EDT SOUTHEAST OF A HOLLAND TO CLARE LINE. (TONIGHT) BETTER MID-LEVEL LAPSE RATES /H7-H5 OF GREATER THAN 7C/ ARE SPREADING NE FROM IL/IN INTO SW LOWER MI. PERSISTENT CLOUD COVER HAS LIMITED INSOLATION...RESULTING IN MLCAPES APPROACHING 500 J/KG PER THE 19Z SPC ANALYSIS...BUT AREAS OF CLEARING ARE QUICKLY APPROACHING FROM IN/IL. A TORNADO WATCH IS IN EFFECT UNTIL 10 PM EDT SOUTHEAST OF A HOLLAND TO CLARE LINE...AND STORMS ARE CURRENTLY MOVING NORTHEAST ACROSS LAKE MICHIGAN INTO OUR SW CWFA. LARGE HAIL... DAMAGING WIND...AND AN ISOLATED TORNADO ARE ALL POSSIBLE. (WEDNESDAY AND WEDNESDAY NIGHT) A FLOOD WATCH WILL BE ISSUED FROM WEDNESDAY UNTIL THURSDAY EVENING. HEAVY RAIN WILL BE THE PRIMARY THREAT AS A SUCCESSION OF SURFACE PRESSURE WAVES MIGRATE NORTHEAST ACROSS LOWER MI ALONG A STATIONARY FRONT. THE FIRST PERIOD OF ENHANCED RAIN IS EXPECTED WEDNESDAY MORNING WHEN A LOW LEVEL JET WILL ENHANCE LOW LEVEL MOIST FLUX CONVERGENCE. SUBSEQUENT WAVES OF PRECIPITATION WILL OCCUR WITH THE PRESSURE WAVES...BUT EXACT TIMING DETAILS ARE UNCERTAIN AT THIS TIME. REGARDING QPF...THE GFS AND ECMWF HAVE HAD RUN-TO-RUN CONSISTENCY AND EACH AGREE WITH THE OVERALL EVOLUTION OF THE SYNOPTIC PATTERN. THREE INCHES OF TOTAL RAINFALL IS NOT OUT OF THE QUESTION FOR PARTS OF OUR CWFA...ESPECIALLY SE...BY THURSDAY EVENING. && .LONG TERM...(400 PM EDT TUE APR 26 2011) (THURSDAY THROUGH TUESDAY) MAIN CHALLENGE IN THE LONG TERM IS DETERMINING THE CHC OF RAIN THROUGH THE PERIOD AS THE UNSETTLED AND WET WEATHER PATTERN CONTINUES TO AFFECT THE AREA. WE WILL SEE THE LAST EFFECTS FROM THE CURRENT UPPER LOW TO OUR WEST DURING THE DAY ON THU. THIS LOW IS EXPECTED TO ROTATE THROUGH THE AREA DURING THE DAY ON THU AROUND THE NEW UPPER LOW EXPECTED TO DEVELOP LATE WED. THE DEEPER MOISTURE WILL LIKELY HAVE MOVED EAST OF THE AREA BY THU. THIS SYSTEM IS QUITE A POTENT UPPER SYSTEM AND WILL TAKE ADVANTAGE OF ANY RESIDUAL MOISTURE LEFT IN THE AREA. WE WILL MAINTAIN THE LIKELY CHCS FOR THU WITH THIS IN MIND. ANY RAINFALL ON THU WILL ONLY EXACERBATE ANY ONGOING FLOODING THAT MAY BE OCCURRING AT THAT TIME. THE BEST WEATHER OF THE LONG TERM LOOKS LIKE IT SHOULD BE DURING THE FRI THROUGH SAT MORNING TIME FRAME. THIS OCCURS AS THE UPPER SYSTEM MOVES OUT OF OUR AREA...AND A STRENGTHENING RIDGE TO OUR WEST BUILDS IN. MILD AIR ALOFT WILL BE TAPPED AND WE COULD WARM WELL INTO THE 60S WITH A GOOD DEAL OF SUNSHINE. LOWER 70S EVEN LOOK POSSIBLE ON SAT IF WE CAN GET ENOUGH SUNSHINE BEFORE CLOUDS MOVE IN AHEAD OF THE NEXT FRONT. THE NEXT SYSTEM WILL BE MOVING IN DURING THE AFTERNOON AND EVENING HOURS ON SAT AS THE UPPER SYSTEM MOVING ONSHORE ACROSS THE PACIFIC NW ON THU TRANSLATES ACROSS THE COUNTRY. A ROUND OF CONVECTION WILL BE POSSIBLE AHEAD OF THE FRONT LATE SAT AND SAT NIGHT. THE MODELS ARE STILL DISAGREEING ON HOW FAST TO PUSH THE FRONT THROUGH. WE CONTINUE TO FAVOR THE SLOWER AND MORE CONSISTENT EURO SOLUTION WITH THE WRN TROUGH DIGGING AND THE FRONT ALIGNING WITH THE UPPER FLOW. THIS WILL ALLOW FOR A MORE WET WEEKEND. EVEN AS THE FRONT MOVES EAST OF THE AREA BY MON...THE STATE WILL BECOME UNDER THE INFLUENCE OF THE UPPER LOW/COLD POOL THROUGH TUE. THIS WILL ALLOW FOR COOL CONDITIONS AND INSTABILITY SHOWERS TO REMAIN POSSIBLE THROUGH TUE. && .AVIATION...(140 PM EDT TUE APR 26 2011) EXPECT SCT TSRA TO DEVELOP THIS AFTN...ESPECIALLY FOR THE TERMINALS SE OF KMKG. STORMS SHOULD THERE IS A SLIGHT /LESS THAN 10 PERCENT/ CHANCE OF S-SW TSTM WIND GUSTS GREATER THAN 50KT OR HAIL APPROACHING 1 INCH IN DIAMETER.

MEADEThe Grand Rapids radar (KGRR), 49 km away, was scanning. The volume nearest the first event began at 20:29 UTC.
6 hail, 1 tornado, 1 funnel cloud, 1 lightning. Local standard time, as filed.
Dime sized hail occurred on the east side of Holland. Swath was estimated based on correlation of spotter report with maximum estimated hail size, and 0.5 degree reflectivity products form WFO-GRR WSR88D.
The tornado touchdown at a landscaping company where it tore a small section of roof of a warehouse building, knocked over several trailers, and blew the windows out of several cars. The tornado then struck a row of 100 yard long turkey pole barns. An approximately 100 ft section of one barn was uplifted and the collapsed. The roof was torn off about a 50 ft section of another barn. Further northeast, several small outbuildings were destroyed and trees were uprooted. Several houses in the path received minor roof and soffit damage with two garage doors damaged. The tornado lifted after partially destroying a 75 year-old 40 ft by 90 ft barn.
A trained spotter in southern Kent county reported seeing a brief funnel cloud three to five miles south of the M-6 and Kalamazoo Avenue intersection.
Hail up to 1.5 inches in diameter fell in a one mile wide swath from Jamestown in extreme northeast Ottawa County through Kentwood and East Grand Rapids. The swath continued northeast towards Belding in northwest Ionia County. The swath was estimated based on the correlation of multiple spotter reports with maximum estimated hail size, NSSL hail swath track algorithm, and 0.5 degree reflectivity products form WFO-GRR WSR88D.
Trained spotters reported that a severe thunderstorm produced hail up to 1.5 inches in diameter on the northeast side of Belding. The swath was up to one mile wide and was part of the swath that began in extreme northeast Ottawa County based on correlation with spotter reports and radar hail products.
Trained spotters reported hail up to 1.5 inches in diameter south of Stanton and just north of Sheridan. The swath was up to one mile wide and was part of the swath that began in extreme northeast Ottawa County based on correlation with multiple spotter reports and radar hail products.
Trained spotters reported that large hail fell from a thunderstorm that tracked from just southwest of Oshtemo east northeast across northern Kalamazoo to Richland. The hail size reached 1.25 inches in diameter two miles west of Richland. The hail swath was up to one mile wide based on the correlation of spotter reports with WSR-88D radar products.
Nine people were injured when lightning struck a soccer field in Portage at Westfield Park. The injured were a mix of adults and students who ranged in age from 12 to 41. Seven people were transported to area hospitals and two sought treatment on their own. One man who was injured most seriously went into cardiac arrest before being treated and released from Bronson hospital in Kalamazoo.
Hail up to 1.5 inches in diameter fell in a half mile wide swath beginning southwest of Cutlerville and continuing northeast through Ada. Some of the largest hail was observed at the Grand Rapids Weather Forecast Office. The swath was estimated based on the correlation of multiple spotter reports with maximum estimated hail size, NSSL hail swath track algorithm, and 0.5 degree reflectivity products form WFO-GRR WSR88D.
