I'm becoming more convinced over the years that snow around here is completely random luck that can happen any winter. 2016 was a warm turd except for the week prior to the storm and another short period of cold around valentines day. 

pretty significant block showing up later in the month, but the Pacific is kinda trash 

need to see if the block can become more west based and exert its will on the pattern, perhaps a forcing more of a ridge bridge up top. either that, or the Bering Sea ridge nudging east into AK

regardless, nice to see an Atlantic block develop... just need to see some other factors become more favorable for legit shots at snow south of the M/D line

It wasn’t just luck, we had a classic west based -NAO in a strong El Niño.

Super Ninos are usually warm and boring unless we get that ideal setup, then a HECS is in play.

That was an impressive block. I remember Bob Chill, PSU, and CAPE called that pattern about 10 days out. The pattern happened perfectly. Then I remember the first model runs that showed the storm. The GFS dropped the first bomb. The others followed. That was about a week out. That was the cleanest tracking event I can ever remember. Models just kept showing that huge hit over and over until it hit. I received 20" here.

sir, this is a La Nina

Seems more like base climo at this point. It’s been cloudy, too, in this fast flow. My buddy confirmed that he’s only made 398kwh this December compared to 1100 last December.

ive noticed that GGEM has alot of digital ice this year. IS that model broken?

It's the iciest model in the world. Always disregard unless something similar is shown by literally every other model. Whole GEM suite is usually too cold at the surface at range (and pretty close to gametime)

If we care about the euro weeklies, looks like things are mostly crappy until the last week (19-26 Jan) when the PAC ridge shifts east into Alaska and BC. Until then…ehhh…

Yeah fwiw we get an EPO ridge by mid month and the NA looks decent too. This h5 look has been persistent over multiple runs so we shall see.

Despite the yellows over us, this isn't exactly a warm look. Anticyclonic ridge out west where we want it, and broad cyclonic trough over midwest/east/NE. Trough NW of Hawaii with -EPO/-WPO and hint of GL blocking, with continued Scand ridging. Second half of Jan could be fun.

well the same weeklies kept it cold through Christmas into New Years until it didnt. I think Bam is going to bust and then call it win when we salvage 10% of January lol

Latest WB EURO weeklies do show the later half of month to be  colder.  Below anomalies for entire month. Pretty good...

we dont need to be in the blue. We can survive +1 or +2......we just cant be orange or red(temp wise)

As Ji said, I don't pay much attention to the colors esp on these extended products. Follow the flow. With the EPO ridge and the TPV in that position, that's a cold look.

GFS and CMC Extended are a carbon copy of the Euro Ext(weekles), maybe even a little better. Nice to see that the pattern progression heading into mid Jan is in agreement among the big 3.
