Because I'm bored and have nothing better to do, I figured I'd over analyze the members, and will do so with each run to see if we can discover an obvious trend.

The numbers are for the TULSA Metro, so if you're reading this from central Arkansas, it's not necessarily going to be spot on.

Here are my findings... 

12/3/19-12Z

0      3, 4, 6, 7, 9, 10, 12, 13, 18, 21,23, 24, 27, 29, 30, 31, 36, 37, 39, 41, 44, 46, 47, 48, 49 TOTAL:25

<1-   1, 8, 11, 14, 19, 25, 26, 32, 33, 34, 38, 40, 45, 50 TOTAL:14

1-3   2, 15, 17, 42 TOTAL:4

3+    5, 16, 20, 22, 28, 35, 43, TOTAL:7

I'll take an order of #21 or #22 please. 

I did that a year or two ago, looked at the Euro ensemble for trends, and it changes too much from run to run to make a difference. Saw like an 80% chance of snow dwindle to nothing in one run, lol

Ok, so I've decided to amend my parameters for the time being on my members analysis. This far out, it's silly to make Tulsa my pinpoint and not count a massive dumping of snow 60 miles away, so I'm going with a 100 mile radius of Tulsa, which roughly means the edge of that circumference hits OKC, Wichita, Fort Smith, Fayetteville and Joplin. So I'll be counting anything that falls in that area.

 

Here are my results from the 00Z run last night.

 

0    5, 9, 10, 11, 13, 17, 30, 31,36,38,40,41,47,48, TOTAL:14

 

<1    4, 6, 8, 12, 15, 20, 22, 23, 29,34,35,37,43,45,49,50 TOTAL:16

 

1-3  16, 21, 24, 25, 32,44, TOTAL:6

 

3+  1, 2, 3, 7, 14, 18, 19,26,27,28, 33,39,42,46, TOTAL:14

 

My next go at the 12Z run in a bit can be directly compared to this as opposed to my last one which only took Tulsa into account. It does seem overall that the Euro backs off an even happening on the 13th and pushes it more to the 16th.

Here's the noon update from today, definitely a large drop in significant snow potential.

That's how it tends to go. 

 

I gave up on over analyzing the Euro members until something more consistent and promising arises.

BUT, I'd say looking over the next 2 weeks it seems like the cold air and moisture are there, all about timing.

Well, all the models currently have a system around hour 240. What's the 12z Euro have after 240?

Friendly reminder that it's been 1,740 days since the Tulsa office issued a winter storm warning.

This is depressing. It’s also been 771 days since the Razorbacks won an SEC football game.  Both of these streaks can end any time now although football will have to wait another 200+ days.

This is insanity.   Before long they're gonna just white out our region like S Florida,  as in dont waste ur time tracking it never happens lol.

This, so so sad and depressing really! And these stupid warm temps(right on track as the last 5 years, shocker..nope) just bum me out again.

Yeah the 12z Euro OP was a little different due to some modeled changes. Mainly a stronger initial system around like the 14th pulling down colder air. The issue is that the flow is just too fast and nothing is amplifying. 

So instead of getting a low forming, you just get positive trough coming out of the 4 corners region.
