Yesterdays official high of 81 tied 1901 with the 9th warmest high of any September 26th here at Grand Rapids. however it was well short of the record high of 92 set in 2017.  The official overnight low of 65 so far would tie the record warmest minimum for any September 27th if it can stay that warm until midnight. (very low chance) That just shows you how fast it cools off here in Michigan in September.

2017 was horrid hot well into October. I think we've gotten this month to kinda balance that one out.

I picked up a decent 0.39" of rain today, better than what models were predicting.

Nice!  The last minute trend I am hoping for here as well

Ended up with a decent  0.44” here. For awhile it looked like l’ld get quite a bit more, but the last hour or two of rain was lighter than it appeared on radar similar to the onset of this event. Maybe more dry air was working in aloft again. Looks like Washington (approx. 15 miles south) got almost another time as much.

It started raining just before I hit the sack last night around 9:00pm and it has continued steadily throughout the night.  Perfect stratiform rain you'd expect in the Fall.  Local reports of about 0.59" which is about how much the models were showing.  It's the first precip we've had in over 2 weeks!

Currently getting some rain w temps in the 60s, as I am enjoying a delicious "Dragon Fruit Juice." Hopefully the whole fills in. Looks like a dry slot has developed per radar.

Same for me. Looking like this first round of rain will end up on the lame side. NBD really since this is the time of year that a small batch of liquid can be stretched a lot further. Besides, as Tom posted several more chances in the near term for SWMI.

Wed-Th timeframe should be a lot better for you in terms of receiving beneficial rainfall and for my area as well. Then comes the first real cool airmass of the season. Get ready! I would not be surprised, if frost and freeze advisories are out. I just hope its not windy by that time.

It's a chilly and calm morning with a temp of 46F.  Instability showers are in the forecast today as the NW Flow continues.  Indoor temp down to 66F but I'm not biting yet to turn on the furnace.  Might wait till the Thu-Fri period when the real chill hits the region.

Happy "National Coffee Day"...cheers to everyone who enjoys their morning cup of coffee! ☕

On my morning walk, it felt kinda chilly and my hands got cold actually.  It's also wonderful to see how much brighter the mornings are now without the smokey skies.  Atm, there are pristine blue skies with a slight wind out of the NW and there was a heavy dew on the grass.  Many trees starting to slowly change color.

Currently at a chilly 52F w partly sunny skies. Autumn is showing its presence. Gotta tell ya, sure feels good to be outta this relentless heat from this past Summer. It almost seemed sempiternal. Anyways, thank goodness we are done w that.

 

Big time chill arrives by weeks end. Highs imby may actually struggle in the low 50s on Friday. Everybody, even Detroit goes in the upper 30s to near 40F Fri-nite and Sat. NW burbs will be looking at some frost.

Dittos for this guy, friend. Yesterday's high of 56F was 24 degrees colder than Saturday's 80F. Add in the contrast between overcast/damp/rainy and wall-2-wall sunshine and the contrast was stark. Not that a 24 deg drop is that huge (heck, that's a hourly obs for our Plains peeps) but it's nice to see autumn temps to finish our BN September in style. Should be a top-shelf day on tap with sun and low 60s around here. Trees are really noticeable already. Well ahead of schedule and especially noteworthy with all the recent frost-less autumns around here.

Indeed amigo, it felt excellent enjoying a BN September for a change. Those chilly nights and mild days were amazing. I might have to turn on my furnace by weeks end (I am thinking Fri at the latest) as temps will tumble into the low 30s and highs not climbing too high.

Trees are more than patchy here as well and like you said, "Well ahead of schedule."

Btw: Looking forward to this upcoming rainevent and chilly temps, along w chilly breezes.

Another nice cool fall day here. Trees are slowly turning. 
 

Here is an updated table I made of precipitation etc at my location since 1990. In the earlier years I didn’t record as many different things. For some reason I wasn’t as interested in tracking temps in the 1990’s as I am now. Sadly, I didn’t even have a high/low thermometer till 1996. I also make other types (monthly/yearly) of tables, charts, or graphs. Not sure how well this will show up as it’s only a photo of a printed sheet. The brighter/darker colors equate to wetter, hotter, colder, etc.

Edit: Bummer, the images don’t appear very sharp on here. Oh well. Good enough for now.

Nice table there. Was going to compare snowfall but I see it is by year vs season. Makes it a bit challenging. Do you have a list of snow totals by season as well?

Seems my CWA has the most action attm. Just getting hammered by CFs!

 

Here's a nice AFD outta my office:

Area Forecast Discussion
National Weather Service Grand Rapids MI
330 PM EDT Tue Sep 29 2020

LATEST UPDATE...
Synopsis/Discussion/Marine

.SYNOPSIS...
Issued at 329 PM EDT Tue Sep 29 2020

-Periods of showers and tstms tonight through Thursday

-Frost/Freeze potential Thursday night and Friday night

-Rain system Sunday

&&

.DISCUSSION...(This evening through next Tuesday)
Issued at 329 PM EDT Tue Sep 29 2020

-- Periods of showers and tstms tonight through Thursday --

Expect an active/unsettled pattern the next couple days as axis
of deep upper trough impacts the Great Lakes Region. While showers
will be possible at any time due to the cold, unstable cyclonic
flow off Lake Michigan, some features of interest that will ramp
up the coverage/intensity of showers at times and lead to some
tstms include:

1) Tonight... A sfc trough moves west to east through the region.
Enhanced low level convergence with this feature as well as an
increase in lake induced capes by midnight should lead to some
locally heavy downpours and perhaps a few thunderstorms -
especially west of highway 131.

2) Wednesday...A potent shortwave passes across srn Lwr MI Wed
afternoon. This feature, combined with the arrival of the next sfc
cold front and some very cold temps aloft (-25C at H5 and mid
level lapse rates near 8 C/KM) will result in numerous showers
and some tstms. Some small hail and gusty winds could accompany
some of the deeper cells during peak heating.

3) Thursday... the core of the coldest air aloft will be overhead
and yet another sfc cold front will be dropping down from the
north. This will support another day of numerous showers and
tstms, peaking in the afternoon. Lake induced capes are shown by
the NAM to be around 1500 J/KG both Wednesday and Thursday.

-- Frost/Freeze potential Thursday and Friday nights --

Winds behind Thursday`s cold front shift northerly and usher in a
very cold/dry airmass. Any lingering lake effect rain showers
should become situated at the immediate lakeshore or just
offshore. Clearing skies and diminishing winds Thursday night may
lead to a widespread frost. Even colder overnight lows are
forecast on Friday night as sfc ridging arrives, with a freeze
likely north of M-46 and frost likely elsewhere.

-- Rain system Sunday --

Guidance continues to trend farther north and wetter with the
system on Sunday. This may be a chilly all day rain type of
system aided by a closed upper low. The showers may linger into
Monday as well.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 156 PM EDT Tue Sep 29 2020

VFR with only isolated showers/MVFR cigs this afternoon and
early evening, then numerous showers and associated MVFR
conditions developing for about a 6 hour period tonight (roughly
03Z to 09Z). This occurs as a sfc trough passes west to east
through the region.

Some IFR is also possible in any heavier showers that occur later
tonight, with the best chance of that happening at MKG and GRR
(where even a tstm cannot be ruled out either).

After a brief lull in shower activity and extent of MVFR early
Wednesday morning, more showers developing again by 14Z-15Z,
along with gusty west-southwest sfc winds to 25 kts. A few tstms
are also likely on Wednesday and some could contain small hail.


&&

.MARINE...
Issued at 329 PM EDT Tue Sep 29 2020

Have extended the Small Craft Advisory through Thursday as cold
cyclonic flow and a series of cold fronts continues to impact lake
Michigan. Persistent westerly flow reaching 30 kts at times with
waves averaging 3-6 feet, sometimes higher.

Prime waterspout set-up will be present over Lk MI the next 48
hours, with convective cloud depths of 20-25K ft and the water to
850 mb temp difference in excess of 15C. This yields high values
on the Szilagyi Waterspout Index.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...None.
LM...Small Craft Advisory until 8 AM EDT Thursday for LMZ844>849.

.DISCUSSION...(This evening through next Tuesday)
Issued at 329 PM EDT Tue Sep 29 2020

-- Periods of showers and tstms tonight through Thursday --

Expect an active/unsettled pattern the next couple days as axis
of deep upper trough impacts the Great Lakes Region. While showers
will be possible at any time due to the cold, unstable cyclonic
flow off Lake Michigan, some features of interest that will ramp
up the coverage/intensity of showers at times and lead to some
tstms include:

1) Tonight... A sfc trough moves west to east through the region.
Enhanced low level convergence with this feature as well as an
increase in lake induced capes by midnight should lead to some
locally heavy downpours and perhaps a few thunderstorms -
especially west of highway 131.

2) Wednesday...A potent shortwave passes across srn Lwr MI Wed
afternoon. This feature, combined with the arrival of the next sfc
cold front and some very cold temps aloft (-25C at H5 and mid
level lapse rates near 8 C/KM) will result in numerous showers
and some tstms. Some small hail and gusty winds could accompany
some of the deeper cells during peak heating.

3) Thursday... the core of the coldest air aloft will be overhead
and yet another sfc cold front will be dropping down from the
north. This will support another day of numerous showers and
tstms, peaking in the afternoon. Lake induced capes are shown by
the NAM to be around 1500 J/KG both Wednesday and Thursday.

-- Frost/Freeze potential Thursday and Friday nights --

Winds behind Thursday`s cold front shift northerly and usher in a
very cold/dry airmass. Any lingering lake effect rain showers
should become situated at the immediate lakeshore or just
offshore. Clearing skies and diminishing winds Thursday night may
lead to a widespread frost. Even colder overnight lows are
forecast on Friday night as sfc ridging arrives, with a freeze
likely north of M-46 and frost likely elsewhere.

-- Rain system Sunday --

Guidance continues to trend farther north and wetter with the
system on Sunday. This may be a chilly all day rain type of
system aided by a closed upper low. The showers may linger into
Monday as well.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 156 PM EDT Tue Sep 29 2020

VFR with only isolated showers/MVFR cigs this afternoon and
early evening, then numerous showers and associated MVFR
conditions developing for about a 6 hour period tonight (roughly
03Z to 09Z). This occurs as a sfc trough passes west to east
through the region.

Some IFR is also possible in any heavier showers that occur later
tonight, with the best chance of that happening at MKG and GRR
(where even a tstm cannot be ruled out either).

After a brief lull in shower activity and extent of MVFR early
Wednesday morning, more showers developing again by 14Z-15Z,
along with gusty west-southwest sfc winds to 25 kts. A few tstms
are also likely on Wednesday and some could contain small hail.

.MARINE...
Issued at 329 PM EDT Tue Sep 29 2020

Have extended the Small Craft Advisory through Thursday as cold
cyclonic flow and a series of cold fronts continues to impact lake
Michigan. Persistent westerly flow reaching 30 kts at times with
waves averaging 3-6 feet, sometimes higher.

Prime waterspout set-up will be present over Lk MI the next 48
hours, with convective cloud depths of 20-25K ft and the water to
850 mb temp difference in excess of 15C. This yields high values
on the Szilagyi Waterspout Index.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...None.
LM...Small Craft Advisory until 8 AM EDT Thursday for LMZ844>849.

Before ya know it, these will be snowshowers for your area.

Nice table there. Was going to compare snowfall but I see it is by year vs season. Makes it a bit challenging. Do you have a list of snow totals by season as well?

Thank you.

The row right between the April and October snowfall amounts is where the seasonal totals are listed or in the wider purple colored row. I guess that’s what you’re looking for? I want to try and  share a link to my Excel worksheet sometime if I can. When I was updating this I didn’t know if 30 years worth of data would fit on a letter sized sheet decently, but I got it all on there.

BTW, Don’t strain your eyes 👀 to hard!

Happy Hump Day!  I can't believe today is the last day of September.  Overall, I'd say its been a great month of weather that practically gave me everything I would have asked for.  A fantastic Labor Day weekend followed by some cooler and wetter weather.  Then we had an extended dry and tranquil weather pattern which was perfection.  Now, we are capping it off on a cool and somewhat wetter note.  I'm really looking forward to October as it looks to provide somewhat of that same flavor with many ups and downs.

Back home from my fall colors photo road trip of Michigan, Wisconsin, and Minnesota. It is a very windy and cloudy one. 58.6*F.

And???? Pics???

Hoping to get north on Saturday for a few hours myself. Worried that by the time I get another chance it may be too late this year. Already, even down in Marshall a bunch of trees are lighting up. Even saw a hardy tree with color. Pretty sure it was an oak. Both '81 and '82 were early color seasons. The first led to the historic cold/snowy winter while the next led to the first modern era super Nino. My thoughts on this autumn being a Nina is that if winter comes in early it will also exit early.
