Yesterday’s chase started after leaving a party at my boss’s house around 6:30. Storms began to fire southwest of the warm front around 6:40, looking pretty anemic at first. Still on the fence about chasing, I drove to Staples in Frandor to stop and check mesoanalysis. Soon after I noticed a small cell east of Dewitt that was broadly rotating on radar. I drove north to get a view of the storm at 7:10. Shortly after I caught a glimpse of the distant updraft base.e2f17d05f1d118ca77b5d2db0ee832f4.jpg

As I approached the storm from the southwest, the RFD clear slot became more apparent, and a broadly rotating wall cloud could be seen.db6c0ba83d4688cdf8287e4bb264d6f1.jpg

After heading east to get a better view, I witnessed the old updraft base move off to the north and begin to occlude. Off to the south, a new and more vigorous updraft was wrapping up. I cautiously drove east behind the storm. After the trees parted, I was greeted with a closer view of the mesocyclone looking ENE on Bath Rd.2437ee411c1a6c05aaf2c6a0e52ebee3.jpg

The RFD surge was mesmerizing. A tornado looked imminent. I noticed wispy funnels emerging from the mesocyclone about 3 miles west of perry accompanied by rapid upward motion. I continued east as my view of the ground became obscured by trees. I stayed west of I-69 not wanting to risk getting too close or missing out on the storm structure. A weak tornado was visible at this point, lofting small debris.f31218e9ad7c1de3caaf9d994403f5d1.jpg

The funnel quickly widened and intensified after crossing I-69.

I repositioned and gained sight of the tornado after stopping at the intersection of Bath and Ruess. I watched the now uncondensed funnel cross Ruess Rd, with a brief power power flash and some swirling debris noted. 08657ddc7a6df19182dadff7d7ad1396.png

I continued east and witnessed a few more ragged lowerings before calling it a night and heading home at dusk.

Awesome photos. A truly great look at tornadogenesis

Except no MCS developed as modeled.  Pure Michigan!!

Only took until 6AM for some storms to even develop in northern lower :arrowhead:

Still got potential for multiple rounds of storms. Down here I’ll get your table scraps unless a overperformer comes around. The cap is an issue

Looking too far east for MBY but I am sure it will find a way to get to Detroit (Wayne county).   It just get tiring that something always seems to go wrong when the models are blasting this area.  :mellow:

Been in the UP a total of 12 days this summer and have had far better T-storms up there!!!  Time to be Bo's neighbor!! B)

Something about storms in the UP is magical. Would love to be on Isle Royale when some come through. I’ll be heading up to the UP end of September. Hopefully a strong low comes through and I can see Superior pissed off. Hopefully no snow showers lol. Still have to visit the porcupine mtns

This continues the trend for here this spring/summer.  Not all the models were showing that line, but its frustrating the ridge wins out the one time you don’t want it to.  There’s plenty of CAPE, but its just hard to get convection going with +12 at 700hpa.  

The upper 70s dewpoints are still on the way though.  Oh boy.  What fun.

Hey I nailed it => "find a way to get to Detroit (Wayne county)" :lmao:  Storms missed MBY by about 20 miles (or less actually).  Oh well. :mellow:  Hopefully something fun happens the next couple days.  Lots of potential at least.

Couple times I was up there with graupel around Sept 28th.  I don't think that will be the pattern this year but you never know in the UP :lol:

While nothing severe, lightning tracker and radar does indicate this been a pretty stormy morning / early afternoon for parts of the city proper and the NE suburbs.

Selfridge has apparently picked up over 1.5" of rain.

Yeah, the Tigers/Cubs are in a rain delay. It looks like the NE suburbs are getting a second round of lighter rain, but may miss downtown.

Maybe I'm confused about criterias over there. The forecast for Allen County, Indiana calls for heat index values up to 106, even though there are no alerts in effect.

 

It’s a bit late now. I thought some of the models were bullish but apparently not. Up to 90/72/100 now where I am. Started the day at 64/56/64

They were originally expecting more storms over SE MI than what occurred.  Most of SC/SE MI would have remained much cooler if the storms/clouds over Lake Erie/Huron were further west like was forecasted/modeled (by most models).  The models that were furthest east were correct and these areas have remained mostly sunny and the push of warmth made if further east.
