Maybe the Euro which tends to be over amped at times will correct somewhat to the GEFS and CMC outcomes. Certainly appears cold enough. The same areas that did well might do well again.
Crazy band Southeast of you, as you are aware, but maybe the end of the storm will have a decent band when it passes from West to East. Congrats on your big snowfall ! Pic looks awesome down there !
31, + SN, 1.5" on the deck, roads still not covered.
Snow and winds picking up. Seems like some better banding forming overhead , not too far North of me the crazy West to East cutoff is clearly visible on radar.
From the site Stratobserve, it appears that a stretched PV might occur during the timeframe from early to mid Jan. Sometimes this can lead to cold air outbreaks and winter storms.
Also, the NAM state may be negative during this period.
Will be interesting to see if the roll forward analogs do indeed result in a more conducive pattern for cold and snow in the East by early to mid Jan 2022. Certainly appears the cold and snow hits out West first.
I liked this scatter diagram the best.
Snow lovers may want to know: Does a cold winter support a snowy winter? Your grandmother would’ve said so and that common sense answer is the right one.
Cold temperatures correlate with a snowy winter better than any of the indices I just discussed.
Below is a scatter diagram of winter temperature anomalies and seasonal snowfall.
Some of the seasonal models keep the negative PNA pattern for the duration of the winter. We certainly will need some luck to score at this lower latitude. Cannot overemphasize the importance of some cooperation from the Pac.
