As of 4:50 am on Thu. (6/11), the Storm Prediction Center has recorded 482 severe weather reports since 7 am Wed. This number will increase before we start over again at 7 am today (Thu.). Some good news…first no tornadoes were recorded. There were several funnel clouds and we saw rotation in several of the storms that moved through, but no touch-downs. Second, no serious injuries were reported. We did have two trucks that were tipped over by the strong winds, one near Holland and the other north of Lansing. Also, despite a lot of trees and branches falling down, none of them seriously injured anyone. Here’s the storm reports map from SPC as of 1:10 am:
The SPC severe weather outlook map for the day was right on…with many damage reports in the Moderate Risk Area that was issued for much of Lower Michigan and Ohio. The Grand Rapids NWS also did a nice job issuing timely warnings over nearly 10 hours…and their area forecast discussions gave advance warning of the storms. This from the G.R. NWS Monday afternoon:
"LOOKING AT WEDNESDAY...WE WILL HAVE TO MONITOR THE SITUATION CLOSELY. SOME MODELS...KEEP THE SURFACE COLD FRONT AROUND INTO THE AFTERNOON AS THE MID TO UPPER LEVEL JET CROSSES IT. AS A RESULT, CONSIDERABLE INSTABILITY FORMS. THIS COMBINED WITH THE RESULTING SHEAR COULD LEAD TO A VARIETY OF SEVERE WEATHER TYPES...THE VERY TIGHT PRESSURE GRADIENT WILL SUPPORT VERY STRONG WINDS HERE IN SOUTHWEST LOWER MI. WIND VALUES COULD SUPPORT SCATTERED POWER OUTAGES."
