September 2017 Observations and Discussion

[Tom]

We are living in an extraordinary period of history in Chicago:

From the NWS:

 

 

 

Dating back to 1871, Chicago's never seen a heat wave of this duration/intensity this late in year, 3 days in row in mid 90s & 4 days >=92F!

[Niko]

The cooldown next week is getting less and less impressive. Also, short lived as well. The 80s return once again, but nothing like what we are getting now.

Crazy stuff!

The Euro is cool still, but now it's showing the prophetical warmup to begin October.

[Niko]

Btw: yesterdays record was an incredible 98.4F smashing the old record of 88F set back in 1922. It neva got this hot all Summer. Although, the humidity was not too bad. This is one uncommon heatwave.

[westMJim]

The record high of 96° at GRR on September 23^rd not only set a new record high for the date it is now the latest’s that it has gotten that hot here in Grand Rapids. And it was the hottest day here in Grand Rapids since July 19^th 2013. In the recorded weather history at Grand Rapids that goes back to 1892 there has only been 8 times it has gotten to 96° or better at Grand Rapids (3 locations over the years) In September. With the last time it got this hot in September was on September 6^th 1960. With the all time record high being 98° on September 2^nd 1913. Here at my house I had a high of 98° but of course that is not official and will not count.

It looks like October will feature a warm beginning. Hopefully, this will lead to a cold November and set us all up for a cold, snowy Winter.

Maybe, that's a hint of a potential 2013-14' Winter coming.

[Niko]

Currently @ 87F.

[westMJim]

Another new record high.  For the 4^th day in a row GRR has set a new record high temperature. The latest reading at GRR is 92° breaking the old record set in 2007. The current temperature here at my house is 94° so that official reading could go higher. 

[Niko]

Temp is at 94F so far with a RF of 102F and a DP of 64F.

[Tom]

Chitown does it again!  5 in a row!

#Chicago-O'Hare has reached as high as 92° so far, breaking previous record high for 9/24 from 1891. 5th straight record high for CHI! #ilwx

[Minny_Weather]

Absolutely pissed rain here about 20 minutes ago. Drove to Western Iowa today. The drive back was terrifying- Heaviest rain I have ever driven thru, and I'm from Houston!

[Andrew NE]

Cold front is getting closer, can't wait for a soaker tonight and tomorrow and some more fall like weather.

[Niko]

Haven't checked my old record, but, definitely smashed a new record today.

[St Paul Storm]

Hit 90 again today. Unprecedented for late September. Highs only in the 60s this week. PWATs tomorrow approaching a record 1.75” for September. A nice soaker in store before the cooler temps set in.

[Minny_Weather]

As has been the case for the past few fronts, this front is about to pass by us. That would make it about 6 hours ahead of schedule.

[Hawkeye]

We hit 90 again today, although came up a couple degrees shy of the last few days.  We have one more very warm day tomorrow(upper 80s), but then get the refreshing air.  I'm very much done with this hot stuff.

[Minny_Weather]

In about 45 minutes, it went from being 78.8* to 72.9* on my patio.

Your in a good spot to get some training storms...

[Tom]

Good luck to you guys out west in the Plains and Northwest (MN)...

 

Latest HRRR looks good for LNK area and just west of OMA...

I just came on to say that training storms are setting up here!

[St Paul Storm]

The Twin Cities just set a record this weekend for the latest stretch of consecutive days above 90F (3 days). Previous record was Sept 21-23, 1891. Historical stuff for sure.

 

Now give me some 60s!

In all my life, I've never seen so many boaters in Lake Michigan! At every launch site empty trailers were parked up and down both shoulders. On the river in Grand Haven where you'd normally see 30-40 boats a quick count gave me at least 100 craft of every size. I guess after a cool August and frigid start to Sept, everybody was taking this last chance to get out one more time. No official stats that I'm aware of kept by the Coast Guard, but this had to be a record of some kind! Especially for Sept, but likely for any month. I'll be remembering this for a long time..

This weather is absurd and its not like its a day or two of heat, its a long lasting heatwave which never occurred all Summer long. Never broke or tied so many record high temps in a row and I mean neva. Go figure.

[Tom]

The record setting stats will continue yet again today for Chitown...this graphic explains it all...

 

 

 

[Minny_Weather]

I think the rainfall deficit for the month is going to be made up for, no?

 

[Niko]

The heat continues today with temps reaching 90-95F with more records likely once again. Unreal.

Crazy!

[Niko]

Yesterdays record high was 95.1 and broke the old record of 86F set back in 1986. It destroyed yesterdays record!!!!!

[NEJeremy]

Had a little under an inch of rain from a couple of brief storms yesterday afternoon and then overnight last night. Radar shows a nice area of moderate to heavy rain getting ready to move in for today

[Tom]

You guys out in NE are making up on your rain deficits quickly! Nice plume of moisture over your state and more to come. Send some here...

Wish I can same the same for my area. My radar looks as dry as it can get. Not even an echo showing.

Is this the hottest Chicago has ever gotten this late in the season?! I hear all kinds of records being broken there.

This is now at least the 4th straight month of no rain at the beginning of the month, and a lot at the end! The LRC shows itself again! 

[Tom]

Boy, models are really struggling on what the pattern next week will look like. CFS/CFSv2 has been most consistent. Maybe after Maria kicks out later in the week we will see better consistency. GEFS have been going back and forth for the opening days of Oct but of late, they are starting to paint a trough swinging through the central Rockies and into the Plains which was not seen at all before.

Neva eva in the history of Chitown's record keeping have we baked this late in the season. Not the records I like to see happen but it's fun to know this is a historic run.

I agree! If its gonna be historical, then, might as well go all the way!

[Niko]

Already approaching 88F. Wow!

I thought you were in MI during March of 2012? Pretty sure we had more records broken than this current streak.

Well, this what happens when arctic blasts happen "out of season". Augtober and Septvember were totally uncalled for, lol. Pretty strange that we had those weeks in an over-all warm regime. This is totally like the scorcher Dec of 2014 after that November chill to remember. 

 

Just gimme cold outbreaks in winter - PLEASE!  

 

And I'm with Hawkeye; had my day at the beach yesterday and I'm done with it.
