September 2025 General Discussion

[Geoboy645]

Looks to be a very cool start to the month for the entire region. Some very impressive cold anomalies showing up for later next week considering the time of year and how far out this is. Definitely a difference from the last couple of Septembers where we were in the 80s and 90s well into the month.

[Frog Town]

Curious if the pattern is trying to tell us something for the upcoming Winter?  When was the last time Summer ended this cool?  Obviously more questions than answers but getting a little excited with how things are setting up.

GFS has Northern WI getting first flakes late this week lol

Incredibly unlikely

NWS Duluth seems to have latched onto the idea of first flakes. 

[Chambana]

Top Tier weather that looks to continue for the next 7-10 days, it’s incredibly dry though. A welcome change of pace with these temperatures as the last several years the 90s seemed to have lingered well into September. 
 

Gotta be the coolest start to September since what? 2013-2014? 

[Brian D]

Having colder wx to start off Sept really is refreshing. Bound to happen tho. Years of hot starts don't last forever. The beauty of weather, and it's cycles.

Expecting to stay in the 60s Thursday.  Perfect weather for first NFL game day.

Solid garden variety storms rolling through the metro this morning. Needed the moisture after a couple dry weeks.

blessed no drought gang

It has been 2.5 weeks without rain.  The lawns have de-greened quite a bit.  We could use a good soak again.

We only had 2" in August here.  Slight chance tomorrow, but overall looks really dry through at least mid September.

Hopefully we get blasted with 5"+ from some remnants in the 2nd half of the month.

My CoCoRaHS gauge caught only .64" in August. Lawn is completely dormant.

This pattern reminds me of living in San Diego. Blessed the weather has been so perfect and comfortable, but damn it I’m getting bored with the lack of variety too lol 

[TheNiño]

Hell yeah somethings happening! 

[A-L-E-K]

EPS look mild in the extended, def not a lot of action across the entire continent next couple weeks tho

There’s an outside chance Minnesota sees it’s earliest accumulating snow on record. September 14th 1964 0.3” fell at International Falls, so if anything accumulates the record will be shattered.

Back in the mid 90's, I was working at a sawmill, and we had flakes flying here in TH during the last week of Sept. That also heralded a rather cold winter. Not saying this would portend that, but definitely a cold start to Fall. Quote from DLH forecast discussion:

The second
cold front will bring a slightly more organized and persistent
area of rain showers southeastward through the Northland today.
Additional showers are likely behind that front as well this
afternoon into tonight. As temperatures fall overnight, showers
may become a mix of rain and snow. A thin coating of snow may
survive through sunrise before melting shortly thereafter. Frost
is possible overnight into Thursday morning, though clear skies
and calm winds would likely be required.

[Brian D]

Low max temp records will probably fall today up my way. A cursory check shows records in the low-mid 50's from 1926.

models not too excited on the snow prospects, think this record holds

GFS wants to ease the dry conditions bringing the remnants of a tropical system up the the lower great lakes region.  Would certainly help out with the drought in the Ohio region assuming the fantasy land GFS is at all accurate.

Euro says what tropical system.  It will be interesting to watch this play out.

This is an interesting random fact. Assuming we dont hit 90F this September, it will be the 7th consecutive September without hitting 90F at Detroit. That has never happened before in the climate record (the previous longest was 6 consecutive years, 1875-1880). The last time DTW hit 90 in Sept was Sept 5, 2018.

36 degrees in Ontario

Picked up a dust settling 0.12" today from the wussy cold frontal passage.
