The annual Perseid Meteor Shower peaks August 11-13 and is the closest thing to a sure thing in when you’re talking meteor showers. The Perseids kick out 10+ meteors per hour at peak, and the darker your setting, the more you will see. EarthSky has detailed tips & diagrams about this summer favorite in Everything you need to know: Perseid meteor shower:
Start watching in the second week of August, when the Delta Aquarid meteor shower is rambling along steadily, reliably producing meteors each night. Then keep watching in the second week of August, when the Perseids are rising to a peak. The Perseid shower is known to rise gradually to a peak, then fall off rapidly afterwards. In early August (and even through the peak nights), you’ll see them combine with meteors from the Delta Aquarid shower. Overall, the meteors will be increasing in number from early August onward, and better yet, the moonlight will diminish until the new moon on August 14, 2015.
Don’t rule out early evenings. As a general rule, the Perseid meteors tend to be few and far between at nightfall and early evening. Yet, if fortune smiles upon you, you could catch an earthgrazer – a looooong, slow, colorful meteor traveling horizontally across the evening sky. Earthgrazer meteors are rare but most exciting and memorable, if you happen to spot one. Perseid earthgrazers can only appear at early to mid-evening, when the radiant point of the shower is close to the horizon.
As evening deepens into late night, and the meteor shower radiant climbs higher in the sky, more and more Perseid meteors streak the nighttime. The meteors don’t really start to pick up steam until after midnight, and usually don’t bombard the sky most abundantly until the wee hours before dawn. You may see 50 or so meteors per hour in a dark sky.
An open sky is essential because these meteors fly across the sky in many different directions and in front of numerous constellations. If you trace the paths of the Perseid meteors backward, you’d find they come from a point in front of the constellation Perseus. But once again, you don’t need to know Perseus or any other constellation to watch this or any meteor shower.

Hard to believe that a raging storm tore through just hours after this idyllic morning in the dunes. But this is from the same day (Sunday) as the monster winds that uprooted and snapped countless large trees…
PS: I’ve been posting lots of updates from the storm on my Leelanau.com Facebook.

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.
