So you're saying the weeklies are volatile?

And they shouldn't be taken too seriously unless they show something consistent multiple runs. Remember a few winters ago when they showed a colder pattern always a few weeks away that never really happened? Just another tool you can use to get a big picture.

Yes that's why the mid range has been horrible.  A lot of the models have done a 180 in the 7 to 10 day time frame from what they where showing some 2 day's ago.

The Weeklies literally just had a run of above average for the month of January a few days ago

You're not wrong. I don't care alot for them anymore. Besides , they're run so often now why are they even called Weeklies. As far as the colder solutions now, they are late thru the Gate. The Controls picked up on the colder solutions sooner. The Blocking should assure the colder pattern as a Sw displaced 50-50 looks to be going to be in Place. IF that Feature were to not materialize then the cold won't be as deep or pronounced.

 A number of folks are confused by the term “Weeklies”. They’re currently called that not because of the frequency of issuance but rather the in-house maps are for one week at a time and also they go out 5-6 weeks.

 Going back a number of years I know they were issued only twice a week on Mon and Thu. I can’t recall if they were issued only once a week going further back. I’m leaning that way though. Maybe on Mondays only originally?

 The more I think about it and try to recall, the more positive I am that they started out being issued only once per week.

 KSAV had 75 today. The forecast is more 75s every day through Sunday. That would give us 6 days in a row of 75ish. Then the bottom falls out on 12/29!

You know its not good when we are relying on the JMA seasonal.. 

 

Now that Christmas is over, lets get real about the pattern. It's pretty obvious we are punting until at least January 10. Its not a torch but more of a wash rinse repeat of cutter, brief cool down, warm up, rain. 

Most seasoned mets and long range forecasts are pointing to the period of January 12-20 for our next real shot of snow. Will that materialize? Who knows but we are about to start wasting prime climo. 

I don't see a January 2022 repeat next month. Maybe we get a week or 2 period but 2022 was cold for most of the month with multiple snows  in different parts of the state.

 We’ll see. But keep in mind that:

-Jan 22 had +NAO/+AO

-This was the PNA forecast as of 4 years ago today through 1/9/22: it was for still -PNA as of 1/9/22. It turned out that 1/9/22 was the first +PNA day of a 38 straight day +PNA. So, GEFS 4 years ago was blind to its start even as late as today:

- Today’s GEFS PNA forecast is eerily similarly maintaining a -PNA: hmmmm

Also, keep in mind that GEFS (and all of the major ensembles) have had a strong -PNA bias over the last 90 days:
