One more day of storm reporting from my neck of the woods…

In Glen Arbor Hit By Knockout Storm, Jacob Wheeler of the Glen Arbor Sun lays out a diary of the destruction of the storm and wrote:

In the storm’s wake yesterday, Glen Arbor residents immediately recognized that the destruction they witnessed was unprecedented for our town. This was worse than the 1987 storm, people said. In fact, it was far worse. The storm was more powerful and more destructive than any other Glen Arbor storm ever recorded. And now we have stats to prove it.

I spoke late this afternoon to Jeff Lutz, meteorologist with the National Weather Service (NWS) in Gaylord. While Lutz clarified that yesterday’s storm was not a tornado (you can blame some of the hyperbole on this newspaper) he did confirm that the straight-line winds which accompanied the sudden thunderstorm reached speeds of 100 miles per hour. That’s strong enough to be called a tornado. More significantly, it blows away the previous wind velocity record for Leelanau County. According to the NWS, on Sept. 13, 2005, a barrage of wind traveling at 63 miles per hour hit Leland and Empire, but not Glen Arbor. But 63 is not 100. Not even close. Nope, yesterday’s storm was the strongest to ever hit Leelanau County, since records were kept starting in 1950.

You can click through to the Sun for more pics and storm coverage and get even more on their Facebook. Jacob also shared the National Weather Service’s Aug. 2 severe weather recap:

  • Multiple rounds of severe weather impacted northern Michigan on August 2nd, 2015. The first severe thunderstorm warning was issued 10:34 am with an additional 27 warnings being issued before the last warning of the day expired at 8:00 pm.
  • The largest hail reported was 4.25″, or the size of a softball, seven miles north of West Branch at 4:55 pm. The large hail was reported by trained spotters and members of the public. There were several reports of damage to vehicles and other property. At the time of the event, a Severe Thunderstorm Warning was in effect for all of Ogemaw County, issued at 4:33 pm. Additional reports of 1.00″ to 2.00″ hail were received from law enforcement, emergency managers, trained spotters and the public across multiple locations in northern Michigan.
  • The 4.25″ hail observed seven miles north of West Branch was the largest documented hail stone ever to impact northern Michigan since records began in 1950 and the largest since 1998 when a 3.50″ hail stone was recorded in Arenac County.
  • Hundreds of downed trees and power lines were reported on Sunday as 60-80 mph (locally 90-100 mph) straight-line winds accompanied the severe thunderstorms.
