Yea, that is what Bluewave said.
I expected late November and the onse tof December to perhaps be wintry, but expect it to shift warmer within the first severday days.
Balance of November-December 2024 Outlook
December Analogs: 2022, 2021,1999
The mild pattern currently in place with the approach of mid-November is being driven by phase 2 of the MJO.
This warmer pattern should remain in place until about Thanksgiving week, when the passage of the MJO into phase 3 may herald in a colder, and more festive pattern.
Long range guidance is beginning to detect that +PNA/-NAO driven regime towards the holiday, which would result in at least colder weather and potentially even the first snowflakes for some locales.
The colder pattern looks to be fleeting, as the month of December should turn very mild in short order with the passage of the MJO in phase 4. The mild regime should remain in place until at the very least mid month.
The first bonafide stretch of wintry weather looks to hold off until at least mid month for most locales.
The polar vortex appears rather unremarkable through the balance of most of November and it would not be surprising for it to even weaken for a time later in the month of December.
While the pattern appears variable throughout much of the month of December, the warmth should be much greater in magnitude than the cold and much of the period(s) of polar blocking will be mitigated by an adjoining southeast ridge. Drier than average conditions in conjunction with the anomalous warmth should help to keep snowfall at a premium across much of the region. The appreciable cold periods will be primarily -WPO driven, per the above composite.
Temperatures across the mid Atlantic and New England should range anywhere from 3-5F degrees above average.
