Yesterday we only managed .05 of an inch of rain in Otsego as two cells moved north and south of us. Our rain came from light showers early overnight. So far for the month our rainfall total is 3.27 inches and 12.48 for meteorological summer.

Yesterday was hot and miserable, with a high of 94° and a low of 71°. Below is a screen grab from my weather station in the mid-afternoon. After the line of storms and wind, we dropped to 80°. The hot and humid air tends to be locked in here in our valley.
Weather History
1982: A strong cold front pushes through and temperatures tumble to 36 degrees at Lansing, setting a record low for the date.
1986: There is an autumnal chill as morning lows fall to a record low of 41 at Grand Rapids and to 36 degrees at Lansing, tying the record low set only four years before.
On August 28, 2020, several rounds of morning showers and thunderstorms trained over the same areas, bringing 2 to 4 inches of rainfall over just a few hours and causing flooding throughout the Metro Detroit area. Scattered severe storms during the afternoon then brought damaging wind to the US-23 corridor as well as large hail (up to 2 inches near Flushing).
On August 28, 2018, a line of severe storms impacted the Tri-Cities and Thumb regions with damaging winds downing numerous trees and power lines.
On August 28, 2013, an EF0 tornado touched down near Brighton, Michigan. The path width was 0.3 miles wide and 2.8 miles long. Peak winds were estimated to be near 80 mph. Numerous trees were uprooted and minor siding damage to homes occurred.
Also, on August 28, 1992, the temperature rose to only 59 degrees in Flint!
NWS Forecast
Forecast Discussion
- Patchy Fog through north, showers and storms through the south Unsettled weather including showers and storms continue to move along the very southern tier of Michigan this morning. These showers will persist, though will continue to weaken through the morning. Calm winds, dropping temps and recent rainfall through north should allow for patchy fog to form near and north of Big Rapids, including along the US 10 corridor. Expect this patchy fog to lift and dissipate mid to late morning. A weak upper level trough will ripple through the Upper Great Lakes today, this will bring another chance for showers and storms this afternoon and evening. Cooler air through the north, along with low to mid high pressure, will stifle convection areas north of I 96. However, a persistent mid level moisture along with the before mentioned trough should allow for conditions just unstable and moist enough for showers and storms, mainly along and south of the I 94 corridor. Storms are not expected to become severe. Conditions will improve into Thursday with fair weather into Friday. Temperatures will be in the low to mid 80s which is only slightly above normal. - Chance for Precipitation Centered on Friday and Sunday A trough currently seen in water vapor imagery over the Pacific Northwest will move through Southern Canada and the Great Lakes between Thursday night and Friday night. A cold front will progress through the area as well during this time. Instability surges ahead of the front on Friday as surface dew points increase to around 70F once again. Cooler temperatures aloft associated with an upper trough moving through combined with the low level moisture allows MUCAPE values to reach 2000-3000 j/kg. So, showers and storms are both expected in the Thursday night through Friday night time frame with severe weather a possibility on Friday depending on the timing of the front. 30-40 knots of deep layer shear will provide the organization for stronger to possibly severe storms. We have currently been placed in a Marginal Risk by SPC for severe storms. Another cold front will move through the area Saturday night into Sunday and this front will change our airmass from summer to early fall. Mostly showers are expected with the frontal passage, but cannot rule out an isolated storm as the ECMWF has CAPE increasing to around 500 j/kg. We are not expecting significant rain totals with these two precipitation events as the cold front will be progressive. 5 day total QPF valid through 12Z on Monday is essentially a half inch or less. - Temperatures Cool Through The Weekend and into Early Next Week Temperatures will remain summer like through Friday when 850mb temperatures will be up around +19C. Highs ahead of the front will push towards 90F down towards Jackson. Temperatures cool into the weekend when the GFS has 850mb temps dropping to +6C late in the weekend. Highs will top out in the 70s on Sunday and only around 70 on Monday. In fact our gridded forecast for Monday has highs in the upper 60s up along U.S. 10. A stark change from the 90s highs that were recorded yesterday across our forecast area. It is that time of year when the first fall air masses of the year drop south out of Canada.
I’m not home, but I see a thunderstorm is over my house currently. Radar estimated nearly 1.5” of rain at my house. If that’s the case that makes about 2.5” of rain the past 2 days. Incredible!!
Correction: the radar estimated includes yesterday so looks like about another half inch has fallen according to radar so that’s 1.5” the past couple days if that’s the case. Incredible!
Hearing rumbles. Storm to my SE just materialized off the backyard.
I’d say I picked up about an inch of rain yesterday maybe a little over an inch. Had some standing water in my backyard. The rain was extremely heavy coming down in sheets. Never lost power here but I know many were not as lucky.
We got lucky here, only a few branches down in the neighborhood. Looks like it was much worse just to my north and to the east.
I’m looking forward to the September weather next week! Probably my favorite month for temperatures- mostly in the 70s… of course we can still get heatwaves, we have reached the 90s several times. But Sep/Oct are usually pretty comfortable
Crazy storms! Wind gusts as high at 74 mph all over southern Michigan yesterday. Damage reports and power outages are widespread.
Horrendous heat indexes yesterday and now multiple power outages! Horrible weather! We did pick up .8 inches of needed rain! Wow!
