Starting a thread this early? Bold! Let's see if it pays off. 

And I'm not even sure why he's interested in a system for the SW Lakes if he's clearly in the E. Lakes? Would usually mean a nice rainer over there.

Tbh, I think you gave him the idea of starting a thread from your "dusting" thread, lol

Hello...

Any thoughts about a possible Low Pressure Center crossing the SW Great Lakes just ahead of Christmas.

Will it transpire; if so, with rain or snow ?

At this range, it's rather risky to start a storm thread but since you did, we'll go ahead with it bc I don't mind taking a chance on this opportunity. 

 

Speaking of chances, there is still ensemble support of a storm that wraps up around the GL's region on Christmas Eve and Christmas Day.  Might need to extend the date of this thread to include the backside LES potential as well.  That is becoming the BEST signal at this range for our SW MI peeps.

Your back is gonna hurt from shoveling all of the rain that GFS is showing for you.

It's certainly a system but looks more like the 1004 mb SLP the 0z GEM showed (i.e. not a wrapped-up bomb). Ofc, this is just a single time-stamp. Does it go bigger from there?

Way too soon to even consider making a thread. Im surprised it got pinged! Its 6-7 days out. Lots can change within this time frame. Oh well, whatever! I guess I am a little too strict.

I seriously believe it was meant to be a "troll thread". Since when do newbies from the far fringe of our sub kick-off threads for another region? When you had just a few posts under your belt, did you start a thread a week out for some potential in Nebraska or Minnesota??

Sorry for starting this thread too soon. I've never started one before and didn't realize a week out was too soon. I just wanted input on the track of that cyclone.

The members of this forum are a great source of weather expertise that I appreciate. Thank-you all !!!

Received about an inch of snow here overnight.

It's no issue! People have started threads a week in advance before (especially during particularly dead periods), it's just not common practice because a lot can go wrong in 7 days.

It's Christmas. We won't hold it against ya if we're jinxed. I feel more likely we are jinxed because this Nina has gone Modoki which is not nearly as favorable as a traditional Nina. You can clearly see it's been acting more like a full-blown Nino!

In back to back runs, the Canadian is flashing a strong southern stream phaser.  Occasionally, it can sniff out a storm in the longer range.  Let’s hope it’s onto something.

It looks like the GFS tried the trough just pushed to far east.  Will be interesting to see if the Canadian can pull it out, it somewhat resembled cycle 1 imo.

With the start of this thread that could put any chance of west Michigan of getting a white Christmas in jeopardy. At this time there is snow to the north, east and south of Grand Rapids but no snow here at all. 

I say we just keep pushing for record low snowfall.  Why not?

How likely is LES for the kalamazoo area? I was looking at the 850 temps and obviously some very cold air is coming in. Thought I heard somewhere the winds predicted to be NW. If i recall correctly from your LES post before we want a Tdelta 13-20 degrees? Whats it look like this time around - (i know this is still way early)?

Not sure but a true NW wind would do you nicely.  Not me.  I need WSW

NWS seems stoked about the LES potential due to extreme instability caused by even greater Delta-T's.

Arctic air rushes in on the backside of this low with 850 mb
temps of minus 15 to 20C headed our way for Christmas eve along
with lake enhanced snow on Wednesday night and lake effect snow
showers through Christmas Day. It will be beginning to look a lot
like Christmas, especially closer to Lake Michigan.

Iirc, they said the lake is running at 6 or 7C, so that'd be Delta-T's of 21-27C. I think your area is in as favorable spot as anyone to benefit at this point. Still a lot of mechanics to get worked out tho wrt N. stream Shortwave, S. Stream SW, and any phasing involved whether it's early bringing us rain, or later to our east and actually enhances the LES scenario.

Tonight's GFS shows the classic NW flow LES band into Kzoo.

The differences I'm seeing between the ICON vs EURO/UKIE/GFS is the way they are handling the southern energy.  The ICON almost closes off the southern stream energy while all the rest of the models have a sheared out wave.

 

 

icon_z500_vort_us_51.png

 

vs...

 

gfs_z500_vort_us_26.png

 

 

If we are to see any chance of a storm, we either have the N Stream trend farther south (unlikely) or have the southern energy maintain strength while the northern piece slides east across the N Sub.  The trailing front has been a part of this years LRC where waves like to track up along it so still some time to see the models figure it out.  Last night's 00z Euro was close to doing so but it phases a lot farther east towards SW Ontario/Eastern GL's.  I have seen, however, the Euro trend bigger with the N ATL blocking and digging the trough deeper and farther west each run.

Check out the trends...

As I write this the 6Z GFS is even further N - a miss synoptic wise for almost all - however I don't by a such N track with the AO negative. The only caveat is the slight upward trend in the AO around this storm periods time--- 590x763_12162354_ao.jpg            Arctic oscillation has been negative and will remain negative for a while forcing a more southern storm track and more opportunities for snow. This index starts to head toward neutral by the 16- to 20-day period. The storm track should shift farther south with less southern branch phasing. I think MPLS sets in a good spot for this one and maybe N.IA, but not much further S than 43 L in -- further E is different. Just my .02. And for what it's worth- E Control is back N , but not nearly has far N as the GFS. Still going to be several days before guidance gets a better handle on this.

The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.
