Hmmm, well it does look like there is a storm in the east on the last frame. But no huge troughs anywhere.

That looks pretty nasty, but what about temps. Does not look too cold for us here in D.C metor for that same time period, last I saw anyway.

I'll check that...

Here's an MRF loop from OSU:

It may not work... If not here's a still:

Ok...... this zonal flow is nothing to get upset over, for one simple reason, it will not last long. As the blocking over Greenland is being reduced, the stronger Pac jet will be able to push the polar vortex Northeastward out of the Hudson Bay, thus no driving force for ANY cold air at all in the East. And the West obviously as the Pac Jet becoems stronger. HOWEVER, there is some higher then average heights over Western Canada, and im pretty sure it will not take weeks for those to push eastward, as they do that though, they will force the NAO to retreat to a - position as they near the Greenland area.

I Doubt anyone has to worry about this.
Now, if we were in mid dec and it showed this id be pulling my hair out!

LOL, better to have these little coughs now then later on IMO.
Like i said, this wont last forever. I think many throw around the term "pattern change" way way too loosely. Folks, a pattern change is a LONG term pattern change, such as going from cold in the east to a developing SE ridge that will likely dominate(according to long wave patterns) for at least a month. A pattern reversal or pattern shift if you will is a cough or just a temporary shift from the current long term pattern. What has been the pattern since a year ago? A trough in the east and a ridge in the west(hence the ongoing extreme drought in the west) this has persisted for quite some time. And it is quite obvious we will return to this after a short term pattern reversal to some zonal flow across america. Again this will not last an extreme amount of time.

[wow]

no longer...

Before hand, the EC has quite a zonal flow with some signs of change afterwards ... strong Eastern Canadian low neg tilts and draws a low off the Carolina coast (possible hybrid storm?) and draws it northward.

Day 10 - 3 day average looks quite interesting .
