Retired DTX met Bill Deedlers Winter outlook for the Great Lakes

One of his best wrt graphics and content. Some real seasons of yore for cold/snow in his analog list too. With 4 of 5 storm tracks favorable to The Lakes, calls for "snowverload" may not be an exaggeration.

The look of a -NAO, -PNA and active sub-tropical jet would be very good for a lot of this sub-forum starting around the end of November (though intially may favor those in the northern half of it).  If the EPO drops after day 10 as the ensembles are trying to hint at that would eventually shift the baroclinic zone far enough south for the Ohio Valley to also get more in the game for early December.

As far as the system this weekend, much of the uncertainty lies with the northern stream piece of energy and the timing of it and how it interacts with the closed low ejecting eastward.  Assuming there is indeed an organized band of snow that materializes, thermal profiles look a bit cruddy.  Cold enough to snow but should be of the wetter variety, especially during the daylight hours.

Last 5 runs of the Euro have been pretty consistent on 4-6 inches from about 30 miles east of me all the way up through Toledo inside 72 hours, then another 3-4 with the second system.  I'd lock it in except it's all alone with that forecast.  Timing is going to be the secret (as it usually is around here until January).  Get something coming through during the overnight our chances for snow increase 2 fold.

Handling of the features for early to midweek has changed on recent runs.  There is more emphasis on a northern stream wave in the northern US/Canada which then allows for the subsequent energy to be somewhat suppressed, at least compared to previous runs which had it going through IA/WI.  Here is Tuesday's Euro vs the Euro from today for comparison.

It is an energetic pattern so it's hard to have much confidence in the details yet.

The Euro is, well, nuts.  There is a 100 mph 850 mb max (actually 105 mph at one point) as the system maxes out at 980 mb in eastern IN.  The wind gust maps spit out 80-90 mph gusts on the back side as a result.  

Odds of happening are somewhere between impossible and yeah right.

Perhaps, but how often do you get to even see such wx model details in this corner of the world? Let alone by the Euro. GFS & NAM typically over blow scenarios left and right as we know. 

I smell a non-bust..
