September 2017 Observations and Discussion

[BrianJK]

D**n, so much for a beneficial soaker. Think we got maybe .25 overnight. Parts of the lawn look like straw.

I just checked and I got .11"...dang!  Better than nothing...

We were just on the northern edge...this map show it quite well...

 

 

[Minny_Weather]

We got roughly .50" here between Saturday and yesterday. Was nice until the sun came out yesterday with the high humidity!

[Niko]

@ Jaster, looks like your luck has turned around fast!  SW MI getting good soaking rains as the wave pivots across your state.  WestJim is prob going to miss out...hope it holds together for Niko.

[Tom]

Might score some extra precip as a meso low is forming off the lake and pushing a band of showers into the Lake/Cook counties...

 

 

[Niko]

Currently cloudy but no rainfall. Temps are hovering in the 60s.

Hopefully, I can score of few raindrops. Jaster might be looking golden.

[Tom]

I always enjoy seeing the lake become a factor locally.  A rather impressive lake enhanced band is producing downpours locally in and around Cook county.

Well, not a pounding SLP, but the beginning of the end has to start somehow. It's the first steady rain with an easterly wind in a long time. Combined with the surprise storm Sunday evening, I'm all  over here!

[Tom]

Most spots picked up an additional .50" of precip from the lake enhanced band in Cook...a spot near Barrington close to .77"...not bad...

[westMJim]

Cloudy and 72° here. No rain not a drop fell IMBY so it is getting rather dry. There is some color in my area with some reds (Maples) and a lot of yellows and the leaf fall off is now started.  This is at lest 2 weeks or more ahead of the usual time for this to happen.

[Niko]

It is actually raining now... and its coming down moderately. Feels great to see some rain falling.

That is one nice area of precip headed your way. Dang!

[Niko]

Maria currently @ 165mph and might even get stronger still.

I think it did..getting a nice dose of rain now.

[Niko]

Still raining!

[Niko]

Jose might be able to steer Maria otc. Lets wait and see what happens.

[Tom]

Holy crap! Maria is down to 909mb with 175mph winds. Good lord! Say a prayer for those in Puerto Rico.

I havent been following too much. OMG

[james1976]

Another beautiful evening here. Out on the deck grilling chicken, potatoes and sweetcorn. Mid 70s. Light breeze.

Btw.....picked up 0.25" yesterday evening.....plus the 0.80" Saturday night. Starting to green up around here.

PS: The locust are LOUD!

[Niko]

Mike Seidel reporting from P.R and its looks like winds are already starting to pick up.

 

Nice radar to watch Maria:

[Thunder98]

Did the NWS Minneapolis got hacked or something? I never seen this before! No low temps and the latitudes and longitudes are messed up.

[Tom]

Near record heat on tap here both tomorrow and Friday.  Local mets suggest 90F on Thu and 92F on Fri (record 92F).  Wonder if we can at least tie it during this late Sep heat wave.

[Tom]

If you need a break from the coming heat?  Don't worry, wait about a week and cooler risks are now coming into more agreement.  GFS/EURO not necessarily agreeing on the strength of the cool down next week.  Euro much stronger than the GFS at the moment.  The cool shot will hit the Plains first early next week, then slide east as expected.

 

00z Euro brings down the 0C 850's into the Midwest later in the extended period.  We have seen this before but never actually panned out.  Need to see what happens with Marie.

[Minny_Weather]

We got a nice cool front overnight. Should make high temps a tolerable lower 80s with a NW breeze and no humidity. Perfect day to show my grandparents around Lincoln! Tomorrow, not so much.

[Tom]

N Rockies are going to get another round of Winter over the next few days as they get hit by a cold PAC system...

 

 

[Niko]

Feels like mid August out there. Hazy warm and humid.

[Niko]

Maria currently at 155mph.

[Tom]

If my current thinking is right, this pattern is going to snap into the new LRC right at the open of October.  Expecting a major trough around the 5th of October to dive towards British Columbia and then make its way S/SE into the central states...give or take a day or two....there looks to be a signal for a SE ridge first week of October.

[Tom]

It's a steamy 89F/67F outside! Woah, what a shock to the system. Thought these hit/humid days were over with but Ma Nature said...Nope!

[westMJim]

I have not looked at ever year, but in looking at past warm Septembers if this plays out we could be looking at the warmest September 17th to the 25 in Grand Rapids recorded history but this will not come close to the heat wave that was recorded at Lansing in 1891. At Lansing in September 1891 starting on the 17th all the way thru the 28th the highs were in the upper 80’s with a couple of 90’s in the mix. The warm temps held over into the start of October at Lansing in 1891. Records do not go that far back at Grand Rapids. October 1891 turned colder and ended up much colder than average at Lansing. November was much colder than average ( -6..3°) and the snow started mid month. December 1891 was warm (+5.7°) January 1892 it was back to cold again (-6.4°) but not much snow fall, February was near average (+0.2°) and March it was back to cold again (-5.0°) But anyway we shall see how this warm spell ends up but as stated it could be the warmest in GRR recorded history.

The last reading at GRR was 83° DP 60 but here at my house I now have 87° with a DP (at my house) of 68°

[Tom]

ORD just officially hit 91F...let the heat wave begin. I think we have a good chance at technically labeling this a "heat wave" with 3+ days straight at or above 90F.

[Tom]

Both Euro/EPS starting to hint at a big trough around the 28th through the end of the month.  Hurricane Maria interacts with a piece of energy hanging back from the frontal boundary that will be forming next week in the middle of the nation.

 

 

 

 

 

 

 

 

Impressive, 12z Euro has the 850's 0C line near the Lakes for 3 days late month...

 

Day 9 & 10...

 

 

[Tom]

Local area is baking!

 

[Tom]

Nearly all the high rez models are showing good rains from the storms that are beginning to fire up in E IA/SW WI....

 

 

 

[Tom]

Record heat in Chi! ORD hit 92F and I think that broke the old record of 91F in 1931.

[james1976]

Yeah local met talkin upper 60s latermext week. Cant wait.

[WBadgersW]

Hope we get some of that rain. We really need some.
