September 2019 Observations and Discussion


Tom

Recommended Posts

While we enjoy the last few days of met Summer, nature is providing many of us up north a taste of Autumn.  On the other hand, our southern members will still have some summer weather to deal with but that will begin to change this month.  I have many reasons to believe Autumn is coming early and hard this year unlike recent years where "endless summer" persisted and extended itself into Sept.  I think it's time to prepare for a chilly start to Autumn.  Let's dive in...

 

Based off my knowledge of the cycling weather pattern and various other LR tools I use, there is a cold period forthcoming to open up the first half of the month of Sept.  My worry is, how cold will it get up north and how much an impact will there be on the ag belt?  Early Frost/Freeze???  Could there be some spots by the middle of the month that will see their first snow flakes of the season??  A very strong signal is pointing towards an early development of the "North American Vortex" which will begin to take shape this month allowing for the early build up of cold and snow up in N Canada.  This will set the stage for strong CF's to inundate our Sub and eventually plunge south into southern Plains.  Autumn is coming...

 

Here are some maps from the CFSv2 showing what may be in the cards...

I like using these snow maps off the CFS model as it has been doing an excellent job since the middle of the Summer predicting snow to begin building over the Arctic and Archipelago. It has been steadfast on the idea of the Vortex pin wheeling in this region throughout the month. Needless to say, "If you build it, it will come"...nature is laying down the foundation of "home grown cold"...

AO/NAO look to cycle back out towards neutral for 7-10 days. This is a good thing, IMO because it gives a cold dome a chance to build back up before the next hard dip.

 

Been a good while since we have seen the MJJA months average negative. Someone mentioned 2002 and 2010, I think those are pretty valuable guides to look forward into the first month of met Autumn.

 

With NAO influence, snow in Eastern Canada is great for us. Without it, central/west Canada is where you want to see it build. We are right on track.

With the Labor Day weekend fast approaching, anyone have any exciting plans?  I think practically everyone on this board will have at least a couple days during the weekend to have cooler than normal temps which is a pretty difficult feat to meet this time of year.  Last night's 00z Euro was showing a couple days with widespread daytime highs in the 60's across the GL's region.  It's been a while since we've had a colder Labor Day weekend.  Thankfully, it looks like there will be abundant sunshine and not much rain to speak of, except for Friday night when a strong CF pushes through the region.

Not sure about my plans yet. Only issue with going back to the feed milling business, poultry doesn't take holidays. Lol. I knew that when I signed up though. I'm thankful for the cooler weather. This year reminds me of 2010 in many many ways except for it seems 3 weeks earlier than that year.

So, basically if I lived in say Churchill up in Canada and the polar bears just jumped off the last of the ice flow a few weeks ago, I got zero summer - ouch!

I hope to visit the National Mall in DC for the first time. I'm excited to see some of those famous monuments I've only seen in pictures/TV/film over my lifetime. Should still be a bit warmer down there no doubt.

For Andie, the GFS ens, as of right now still won't break the base of that ridge out of central and west TX. I hope it does soon. That hot air has been anchored there for 6 weeks. It has to break down at some point as it migrates out to join the EPAC ridge complex on the west coast. It may just be one of those years where TX just gets a "Norther" out of nowhere one day in early autumn and "boom", as they say in boxing...."Its aaaaaallllllllll over!!!!" "Down goes the heat!" :)

Like the flip of a switch.

I was not expecting any rain until late Monday, but tonight's disturbance has thrown decent moisture up into east-central Iowa.  The HRRR is still failing to see it.  I may have a few tenths and there's more moving up from the south.

Well, the GFS is kinda waffling a little on the 4 distinctive cold fronts now and making a wash out of the end of the the thing. We just have to keep watch it. The north wont have a problem cooling off, but getting them down here may have been too good to be true.

Waiting and seeing....

It's that time of year when farmers and wx enthusiasts begin to look for signs of Autumn.  None more noticeable are when parts of our Sub see our first Frosts of the season.  The map below illustrates on average when we would expect our first Frosts.  

 

Med_First32_FreezeDate.png

 

 

While on the topic of Frosts, using the BSR rule from a storm that tracked near the southern Aleutians islands back on 8/20-22, I'm seeing the models showing signs of it during the 2nd week of this month (9/7-9/9).  Might this be the first big cool down of the Autumn season for many us post storm???  I'm leaning that way and would not be surprised if there are frosty mornings in the near future up north.

Only 44(ish) more days to go. :)

I hope sooner. Maybe by September's end, but also maybe wishful thinking.

I'm looking forward to hearing who gets the first snowflake !!

 

We'll see 92-93* today but the air feels different.

The moisture yesterday was a real shot in the arm.

20% chance of rain the next few days but we got about .60" yesterday.

Next week shows a nice, cool airmass coming which has my highs struggling to hit 70F. That should feel awesome.

Niko, if things work out just right with Dorian and the trough coming down out of Canada next weekend, places around the GL's may struggle to get out of the 50's!  The pattern leading up to the following weekend could really buckle into a major trough across the GL's/SE Canada.  Early Frost potential is in the cards for some peeps across the north.  My gut feeling has been saying all along to look for a colder opening to September and its certainly leaning that way.

Taking a look at the wx pattern that is poised to set up across the N PAC, it is opening up on a very active and intriguing setup which provides us some clues of what to expect towards the 2nd half of the month.  Storm train???  Strong troughs???  Check out this animation below off last nights 00z EPS which is showing a major Aleutian Low (upper 960'smb)? targeting the islands and taking a nice track just west of Alaska with the potential of a couple more storms to track in this region over the next 10 days. Nice way to open up September, ay?  Boy, if your looking for Autumn-like weather, this is what you want to see near the Bearing Sea to open up September.

 

I got this feeling that we are going to see the atmosphere primed for some strong, wound up Autumn storms to effect our Sub this month.

Septembrrrr!!!  Yikes, if this trough phases/buckles next weekend all signs point to early frost/freeze potential up north.  My target dates of 9/7-9/9 for a big storm/trough using the BSR is starting to show up on the ensembles.  #AutumnIsComing

Its always interesting to see if the Farmers Almanac will hit on their long range forecast.

I never put any real stock into it regarding Texas as our weather seems to have a mind of its own sometimes.

Anyway, here's their winter forecast map for winter 2019-2020.

AO looks to trend positive for the first time in a few months. Heres hoping that changes after ice starts building back up there.

I don't mind seeing this spike in early Autumn for a number of reasons, most importantly, it'll allow the Arctic cool off quickly and build up the snow pack.

Welcome to met Autumn!  My goodness, but what a way to kick start the month of September with nature's beast #Dorian now a Cat 5 (160mph) winds!  Quite a phenomenal storm system and one that still may impact Floridians.  To close for comfort.  These systems have a mind of their own and may jog enough west to inundate the east coast of FL.  I read that at flight level winds have reached 170mph...just an insane amount of energy.

I had 0.17" of rain fall overnight here at my house.  With cloudy skies the current temperature here is 57. A short recap of August for West Michigan. Over all West Michigan had a near average August with Grand Rapids coming in with a mean temperature of 70.7° and that is a departure of just -0.1° The high for the month was 89 on the 4th and the low was 49 on the 31st. At the airport they reported 3.41" of rain that is below the 30 year average of 3.59 for August. Muskegon came in with a departure of +0.4 the high for the month there was just 86 on the 13th and the low was 48 on the 31st with 2.16" of rain fall well below the average of 3.39" At Kalamazoo the departure there was +0.5 the highest for the month was 88 and the low was 49 Kalamazoo only recorded 1.73" of rain. and in central Michigan at Lansing the departure there was +0.3 with the high for the month of 89 and the low of 47. with 1.57" of rain reported

The high so far at GRR today is just 68 if this holds (it is now down to 65 here at my house) this will be the coolest high for September 1st at Grand Rapids since 2003 and very well could be a top ten coolest. 68 would put it in a tie for 10 place and a high of 69 would put it in a 3 way tie for 11 place.

Let's take a look back at the historic August and summer of 2019. Here in Grand Island we ended with the 2nd wettest summer on record and the wettest since 1908! 1908 beat 2019 out by only about half an inch. We ended the summer with 21.25 inches which is pretty much our yearly average! August alone measured a foot of rain. This wasn't even close to the highest total in the area either, Doniphan which is about 10 miles away measured over 16 inches :o

 

I love seeing the extremes. Look at 2012 and compare it to 2019. Just incredible disparity. Weather patterns are truly fascinating.  This is one year that won't soon be forgotten around this area.

Back in Michigan guys. Came back early Sunday evening. Nice to be back in my home.

 

Cannot believe how strong Hurricane Dorian is. Those people in the Bahamas are really getting hit badly. Good luck to them down there and hope they stay safe.

 

Floridians, don't let your guards down. Stay alert and evacuate just in case it takes that westward track.
