I bought my home based on the age of the drainage system in the area, I grew up in a 1950's build home in Metro Detroit and had enough of flooding.

Aside from that, I'm in Manistique right now, I dont think areas east of 23 got much. Anyone have a total event qpf map?

lots of pics/discussion in the august thread on this. It didnt get its own thread because it really wasnt predicted. Its actually insane to see the widespread area of 4-5" rain that was not predicted. Here is a copy of my post

 

Its just a mess everywhere. Worst Ive ever seen. Had 4.39" in my backyard, the biggest amount Ive ever recorded in a single day. The 4.57" at DTW makes it the wettest August day and the 2nd wettest day on record, behind only 4.74" on July 31, 1925. The water was knee to waist deep in the streets, and water flooded or seeped into many basements (including mine). The pictures of 10 feet of water flooding area freeways is just incredible. At DTW, 1.24" fell in 24 minutes!

I haven't seen one posted, but it seems the heaviest areas went east of I-75 from watching the radar. I'm just west of 75 a couple miles in FNT, the heaviest rain was just to my east, coming from the southeast. I think your area had less rain.

 

That said, I went down to check my sump pump again a few minutes ago, evidently it had become unplugged when I was moving stuff around. Luckily, it was several inches from overflowing when I plugged it back in!

Here's the best I got (very similar map posted before by somebody else)

Don't see this every day.

River or I-696? You decide.

Also, I looked up the #1 record holder for daily precip in Detroit (7/31/1925) and there was a similar (synoptic low-driven) setup, albeit more east-west oriented with the path of the (shallower) surface low:

 

7/31/25 8AM

Consistent with the differences in the track of the low, the 1925 rainfall event was more east-west oriented too, with Grand Rapids (1.5"+) and Buffalo (1.5"+) getting big totals, but Toledo only got 0.4" just an hour south of Detroit the same day Detroit got 10 times that. Today there was a solid 3" or higher corridor from southwest of Toledo, up to DTW and points east and northeast, then curving northwest up to Saginaw and Bay County surrounds.

 

As for me, I "only" got ~1.25" from this event east of KARB. :whistle: It was consistently dark out nearly all day though save for a brief patch of sky I saw around 9AM and 9PM.

Crazy impressive. Is this a historic rainstorm? Any Mets care to chime in on what caused this. Was this predicted?

 

I'm not a met, but it was basically fall-like synoptic forcing (deepening surface low with upper level support approaching detroit from the southwest) came together with summer-like atmospheric moisture content and went to town over a surprisingly wide swath of a metro area.

 

It was historic, although to be fair we've gotten a few rainstorms approaching this one displaced a county or two west within the past few years, but even those have been some isolated 4-5" reports, not widespread 4-5" reports across nearly an entire county's worth of area like this, and not over a major metro area. There's a 6.25" report from DTX from near Southfield. That's almost 20% of the annual average precip for this area falling in a couple of hours. Nuts.

I'm not a met, but I'm sure part of it, as is the nature with convection, was pure luck.

 

But also, there was a rapidly deepening low pressure system developing over the city (as a northern and southern stream wave phased) with nearly tropical moisture levels that helped to seal the fate, so to speak.

 

As stated before, some models did hint at this outcome, but it was such an anomalous event still...

At least right now it looks like the stuff coming later to day will be scattered, however any appreciable rains at this point could really exacerbate things.

 

The east side looks to most at risk today, as that's where the best combined instability/low-level convergence will lie.

 

But ultimately, however much daytime heating we see should dictate the coverage/intensity of any t'storms today.

I cannot recall ever getting flooding quite like this. My neighborhood got lucky and dodged the worst however streets are still under water in spots. All my friends in the Detroit burbs called in to say they couldn't make it to work today as all the freeways are closed and flooded. Yikes. Storms are firing up east of us in Canada and I hope they stay east of us. We've had enough rain for the month thank you! 

 

I was actually going to make a trip into downtown today to meet up with some old buddies but I had to cancel on them last week for something unrelated. Assuming they are still meeting today, canoeing will be their only viable form of transportation. Is there any serious flooding in downtown or is it all in the neighborhoods? 

 

The surface streets from what I hear are mostly fine.

 

It's the freeways that are still bad.

 

More storms, unfortunately, look to be brewing just to the NW. But for now, things should dry up some with the sun out.

MSP is telling people NOT to travel around Detroit today if at all possible. 

 

I'm watching those storms as much as I can. The cells south of Cadillac seem to be going due south ATM, but cells in northern IN are going almost due east. I deduce that the WEMI cells at some point are going to start turning toward the east, but hopefully far enough south to avoid the Detroit area. Time will tell.

Not sure about data on the Clinton River, but its highest I've ever seen it in the Clinton Twp area. (I work with the Department of Roads, so i've had the pleasure of setting up road closures all day for the flooded roads)

I took some pictures of the flooding near crest. Ill try to upload them this afternoon on the desktop.

I saw a picture on twitter: an underpass, with a 14'2" indicated height. Water was about 12ft above ground (2 ft under the bridge). Perhaps near DTW.

 

Toledo Express (TOL) had 2.04" of rain. My parents had 4.8" of rain. Toledo Executive Airport (TDZ) had 3.21" of rain.
