map test

It begins, Out with the Old and in with the New ! 8-10 day means showing the legit pattern change getting underway by the 2nd week of January ! A nice PNA Ridge and developing NEG AO / NAO !

Very nice change to POS Heights over the top, and a Blocking pattern. I continue to think between Jan 7th – 12th time frame, the M/A has a good shot at the first snow of the season.

Mid and LR models will flip back and forth with any details until the beginning of January. This new pattern is also showing a very nice Split flow, with the STJ and Polar jet possibly phasing in the Eastern CONUS. Miller A / Southern Slider Potential here folks. Let the party and Winter begin !
