Part I - January 2020 Weather Discussion for the PNW


Recommended Posts

Happy New Years everyone! 2020 will be here in just a few short hours...

 

Looks like 2019 is ending on a rather warm note locally.

Average high this December is 41.5 (+3.1) and low is 27.1 (+6.5) with a monthly Mean at 34.3 (+4.8) degrees.

 

A contrast to the cool anomaly in late summer and early fall.

The last 3 GFS runs have all showed a Columbia Basin cold pool in the long range.

 

Not to mention cold in the Western Lowlands as well.

It's only exciting to me once it's within 7 and better yet 5 days. We shall see.

It's called clown range for a reason.

This is really good for an EPS mean this far out.  Notice how the strongest minus anoms are right over WA.

Here's to January 2020 and all the snow it will bring!

 

This is going to be good.  I have felt it for many weeks now.  You can ask my friend that I have been texting all season about how big this winter is going to be.  He knows when I'm serious.

I definitely think some, if not many people on this forum are going to see snow at some point over the next 2 weeks.

 

Other than that, I'm trying to keep expectations low. But the pattern predicted by the GFS operational and ensembles is certainly one that could repeatedly deliver

solid snowfall if everything lines up right.

Finally a cold January coming!

 

It sure looks like it.  It's looking more likely we could have a long lasting deep cold wave.  At the very least it's going to be better than most Jans since 1982.

I was pretty stoked about the notable improvement on the EPS tonight also.  Quite a bit sharper with the GOA block and a lot chillier on the 850mb temp mean.

Going to be interesting to see if the high latitude part of the blocking complex is for real or not in future runs and other models.  The outcome is way colder with that.  Probably a Jan 1969 look to the 6z.

Big snowstorm for the Washington lowlands after hour 240, very nice to see. I like that each consecutive run also shows some offshore flow as the lows dive in.

It's nice to see for sure but I wouldn't put too much weight on it, the 06z has a history of showing the goods. 

I just love the overall trend and timing has gone way up.
