I really wish they'd pick a different color for "ZOMGZ INCREDIBLY HEAVY SNOWZ!" than PINK, lol...always gives me that momentary "mixing!?" panic.

Cold Winter showed its hand when the Arctic was freezing this Summer.. In August we went sub-5000dm, which was the coldest N. Hemisphere H5 on record for Aug. You know the eastern US starting cooling down around that time, too. I ran the analogs, and it fits a perfect warm-to-cold season progression since 2012. 

So much for the early Fall worries regarding the extreme - PDO.  

Also of note is the continued deeper and deeper dive of the AO leading us to next week's bitter arctic invasion.

18z ai gfs has our 1/29 Miller b as an early developer that hits us again. 

Op also has it but doesnt develop the Miller b quite as aggressively/early as the AI. This is a window to watch as a discrete threat is across most guidance now.

Ai gfs has something day 8-9

Euro and CFS weeklies show cold indications for 16-30 day based on top-matching upper level analogs, either Feb 2007 (Euro) or Feb 2015 (CFS).

Those two Februaries, 2007 and 2015, were extremely cold (especially 2015) around here.  The two coldest of that month in the 25 years I've lived in the area.  In 2007 we just missed a big snow for the Valentine's Day event but did get like 3" sleet that froze solid.  We also had a couple of other decent more minor events along with the cold.  In Feb. 2015, we scored better with snow relatively speaking.  If we get something on the order of those two, it could be quite a time here!

WB latest EPS weeklies likes the 3rd week of February.

For the cold outbreak following the storm, at least on the GFS I've noticed a consistent pattern where the VA and even NC piedmont gets sub-zero lows and we're stuck in the single digits. This isn't elevation dependent since it's placing them in low elevation areas to the south and snowpack is high everywhere. Instead it looks like it's because of low-level winds that are calm down south but present at 925mb above Maryland. I've seen this same thing in forecasts after snow events last year and I still can't understand the dynamical reason for it. Is Emporia VA and thereabouts really a better place for vodka cold following a storm pass than MD?

End of the GGEM 0z run is a real nail biter. Incredible closed trough in the south after historic snows trying to pull north the coastal. Wow!
