LC throws hot water on a cold Dec, but gives hope for Jan-Mar
There will be a transient cold intrusion through the eastern two-thirds of North America November 28 - December 5. Then a new subtropical high appears close to the Bermuda position, and starts the warming process all over again. Another cold frontal passage is possible through the northern third of half of the U.S. in the second week of December, but most of the predictive schemes have backed off on the idea of a cold December. I am confident that set-up will change for January, February, and maybe the first week of March, a reaction to the rise of SST anomaly in the equatorial Pacific Basin (likely a positive neutral ENSO in the spring). This should be a well-defined "second half" or "back loaded" winter, when the powerful southern branch jet stream wears down the positive 500MB height anomaly in the southwestern Atlantic Ocean. For now, except for the occasional Alberta Clipper or Colorado/Trinidad "A" storm, it is a normal to warm prediction from Texas and the lower Great Plains through the Mississippi Valley to the Eastern Seaboard.
