As long as the cold air stays in the contiguous 45 states (in keeping with the theme of this mini-thread and Canada picking up CA, OR, and WA), I'm fine.ticka1 wrote:winter geeks united! love this!DoctorMu wrote:Putin has negotiated an agreement with Trump to hack our La Nina and send Siberian air through Alaska and east of the Rockies intermittently.

The overnight guidance continues to advertise a potential significant pattern change as we start December. The GFS Super Ensemble Day 11+ Analogs finally have some memorable analog years such as 1983 and 1972 as well as 1997 which were brought Texas wintry weather. If the ensembles are correct, a strong Blocking regime may become established and the Teleconnection Indices agree with this potential.
The 06Z suggests in the longer range as we begin December, a potent sharp cold front will arrive with additional disturbances following in the NW flow aloft. While it is still too soon to know with any certainty how events will unfold in this very long range, the indicators certainly are suggesting the potential does exist for a significant pattern change as the Pacific flow relaxes and a more typical wintertime pattern develops. Stay Tuned!

We continue to see changes brewing in the Hemispheric Pattern as we turn the calendar to December. The 12Z longer range European model agrees with the GFS suggesting a cooler and stormy regime may be possible. If the trends continue, I would not be surprised to see more frequent cold fronts arriving every 3 to 5 days with progressively colder air surging South from Canada as we move further into the new month.
The afternoon updated Climate Prediction Center Day 11+ Analogs suggest 1983 may be the best example of the potential sensible weather pattern as December begins.

Hoooo boy, the Euro and GFS long range have the dam breaking as we approach the end of the 2nd week of December.
-20 to -30F entering Montana. EPO tanks as well as we approach mid month. We have a front every 2-4 days from each run.

Wow look at the amplitude of the ridge forecast to build in over the North-Northwest Pacific on Day 15 per ECMWF Ens
