According to the SPC forecast for SW Michigan, we are now in the marginal (level one) risk for severe weather later today into early Wednesday morning. The warm airmass should stay in place today and tomorrow before being replaced by much cooler air pouring in from Canada signaling the end of summer. Daytime temps are predicted to drop into the low 60s with overnight lows in the 40s.
Yesterday we reached 78° after a morning low of 59°. Today’s sunrise is 7:27 am and sunset is 7:43 pm.
Forecast Discussion
- Convection possible this afternoon through Wednesday morning - Showers across portions of WI early this morning should dissipate as they move east towards our area and encounter a stable airmass here. However we expect scattered convection to develop across portions of our area this afternoon due to gradually increasing elevated instability north of the warm front. Strongest storms may contain hail and briefly gusty winds and the overall svr wx threat later today looks marginal. Scattered convection is also likely to develop very late tonight and Wednesday morning along and just ahead of the approaching strong cold front. It is noted that the CAMs are not bullish on convection. This is likely tied to unfavorable frontal timing for our area and that the most favorable upper level dynamics stay north also stay north of our area. However we think the CAMs may be underdone with convection given ample low level moisture and strong omegas with the cold front in conjunction with favorable kinematics and as deep layer shear increases to 30-40 kts. Given all this I would not be surprised if we had a few severe storms late Tuesday night into Wednesday. - Much cooler late this week - Strong caa will occur after fropa and h8 temps will plummet to around 2 C by midday Thursday. Max temps will struggle to reach the lower 60s by Thur/Fri with mins mainly in the 40`s but some colder readings in the 30s across our north/ne area. Lake induced rain showers are also forecast Thursday mainly west of US-131 given the nw to nnw flow regime and very high delta t/s. Temps will moderate a bit for the weekend and return to near normal for this time of year.
I’m downtown Chicago for a couple of days for work. Severe Thunderstorm Warning just to the west. Looks like it will miss me.
Beautiful Fall night now the rain is over INDY
0.43” total rain here. Just had a decent little rainbow as well.
Total rainfall today is up to 1.1 inches!!! This is after a major downpour about 45 to 60 minutes ago! The incredible summer keeps rolling and the GR NWS weather service does a great job with their state of the art temperature equipment! Keep it up! Incredible accuracy!
ADA – 2/10 of an inch of rainfall snuck through here today. A small amount of lightning and thunder were enjoyed. Take what you get 🙁
The sun is now back out. The two rounds of rain have dumped a total of 0.19″ of rain here in MBY. The current temperature here is 66 with that sun.

I’ve been told some of the stoplights are out along the East Beltline. Traffic is a nightmare.
Just had the most intense thunder and lightening here in a long, long time. Not much rain but like I said a lot of thunder and lightning.

Just gusted close to 40mph I’d say at my house. Getting the gust front from the storms just NE of town. No rain yet though.
Not much rain here, only 0.07”. Suns out again.
Just got back home. There was 0.10″ of rain here in MBY. To answer you question on the departures so far this month. Like has been the case for a while the means have all close with a mean of 68.3 at GR that is +2.7. Holland 68.0 +3.1. Lansing 68.6 +4.0 and Muskegon 69.9 +4.4. As has been the case for many months now Grand Rapids has been cooler compared to average than other locations.

GR the relative icebox once again. What a joke! I think I’m done referencing NWS GR temps. They are almost always about 0.5-1 degree cooler relative to average than the rest of Lower Michigan.
So far 0.14” of rain at my house so far today. We shall see what more we get.
Them temps will drop as the rest of September looks to be below or near average FALL!! INDY
Now some thunder, lightning and mod rain! I think I only had to water my lawn 2 times all year! Definitely consistent rain around GR all summer! Incredible!
So much for the rain fizzling by the time it gets across the lake! Current conditions = moderate rain and cool temps! Wow! So much for temps around degrees today!
Great summer, especially no heat waves, plenty of sun, many days and months with near normal temps! Incredible summer!
Welcome Fall with some more Fall like temperatures love it!! The trees will really be popping colors fast if we can get some lows in the 40s this weekend beaty at its best ..INDY
I’ve been in Columbus OH the past few days for work. It’s very warm and muggy down here… this has felt like a long summer to me
It’s been a great summer
Also…sorry you have to see all that buckeye stuff 😉
Quite a bit of lightning just to our NW. Could use a little rain since it’s been so dry again this month but looks like it’s falling apart.

Looks like true summer weather this year was from May 9th to September 21st. That’s a whopping 136 days!
I think it has been a nice summer. Some hot days to swim and some nice days to get some work done outside. With this cooler weather I will be splitting some of my flowers and moving them. By chance anyone know how to keep sassafras from coming back up? We cut a bunch of saplings to create a flower garden, but they keep coming up.
This sure has been a warm September so far. The average H/L after the first 19 days this month has been 77.9/58.6. And that said yesterday was no exception with a H/L of 79/62. There was a trace of rain fall reported along with 91% of possible sunshine. The overnight low so far at GRR has been 55 and here in MBY the low and current temperature so far is 54. For today the average H/L has dropped again and is now 72/51 the record high of 90 was set in 1931 and the record low of 33 was set… Read more »
What is the current departure from average?
