September 12
On September 12, 1986, a 3 day period of persistent rainfall that caused the worst flooding in 50 years finally ended, which resulted in damage between 400 and 500 million dollars!
September 13
On September 13, 2019, severe storms tracked across the Metro Detroit and Thumb regions. Hail up to golf ball-sized was observed in southwest Oakland County while a wind gust to 72 mph was measured over the Detroit River.
On September 13, 2008, tropical rains started to fall over Southeast Lower Michigan. In about 48 hours from the evening of September 12 to the evening of September 14, 3 to 6 inches of rain fell. The rain was in part due to a slow-moving cold front that crossed Lower Michigan associated with moisture from a Pacific tropical storm and the remnants directly from Hurricane Ike that struck the Texas coast on September 12.
Also on September 13, 1962, in Wayne county, there were wind gusts of 73 mph along with a thunderstorm.
September 14
On September 14, 1996, a pressure of 993 MB was recorded in the “eye” of an intense storm system that formed over Lake Huron that had many uncanny similarities to a tropical hurricane. In fact, this storm was nicknamed the “Huroncane”. By 2 PM on this day, the “eye” of this storm measured 20 miles across and was ringed by tall cumulus clouds resembling an eyewall of a normal hurricane. At one point, this storm even produced tropical storm-force winds (39-73mph)!
September 15
On September 15, 1939, the temperature rose to a record 100 degrees in Detroit for the day. This was the highest temperature record for the whole month of September.
September 16
On September 16, 1955, Flint experienced a record high of 90 degrees. This marked the beginning of a 3-day record high streak in Flint, with the 17th and the 18th experiencing temperatures of 94 and 93 degrees respectively.

Forecast Discussion
-- Dry Weather Through Thursday -- The line of showers and storms created by the frontal pattern continues to move eastward. Cooler, drier air will filter into the region today. However, cooler is only relative as maximum temperatures will remain above normal. High pressure will build over the region allowing for fair/mild weather to persist through most of Friday. -- Next Chance of showers/storms Friday into Saturday -- An upper level trough moving through Canada will have an associated frontal system that will extend from NE Canada into the Midwest. This will be the next chance for precipitation. There are some timing concerns as the air will be fairly dry so any precip will have to moisten the atmosphere as it approaches. Given the latest soundings, this system will enter a moisture starved atmosphere with little in the way of thickness cooling occuring. The best opportunity for rain will be early Saturday morning when diurnal cooling along with dynamic lift could allow for light rain Saturday morning, mainly along the US 10 corridor. -- Warmer Then Normal Temperatures ahead -- The biggest trend over the next week is the upward trend in temperatures across the region. Southwest Michigan was warmer then normal today and that will continue into next week. While the approaching front will stall the warming temperatures, the +1 to +2 sigma signal from standardized anomalies shows an upward trend in the mean temperature. Given this,CPC`s 6 to 10 day and 8 to 14 day outlooks have above average temperatures trending. Summertime temperatures in the mid to upper 80s are expected through the weekend and into early next week.
Phew, we had 90’s in Michigan again yesterday!
We also had highs just in the low 60’s and lows as cool as 40 in Michigan yesterday!

Well outside West Michigan however
It was hot out yesterday
The overnight low both here and officially at GRR was 57. Here at my house there was no rain yesterday. With the clouds and the wind most of yesterday was rather comfortable. I cut the grass and it was not bad out at all and by the time I went for my walk at 7 PM there were some people with light jackets on as the wind did feel cool by that time. At this time it is sunny and 63 here. I had to take a quick trip up to Bay City on Monday I managed to miss most… Read more »
over here it rained for 5 min and then it was over
It’s been a warm start to September and only getting warmer. Looks to be the warmest start to the month since 2016.
Get colder!
i got a little bit and at one time yesterday i had 3 flashes of lighting and then thunder, don’t know what was up with that
Not sure how much rain we received yesterday, but it was a bunch. There is standing water out back behind our house.
It looks to have been spotty as officially Lansing only recorded 0.08″
