Jan Medium/Long Range Disco: Winter is coming

Recommended Posts

Trying to be positive.  Point is that it looks like it will stay seasonal around the 21-25 or so and then turn sharply colder again as we enter February.  I would love one big storm. 

lol your positivity usually lasts for about 6 hours
I think the idea of a great winter is over. Now are are 1983 2016 hunting

They have maybe 0.5% more skill than throwing darts. Mostly printing out old El Niño analogs from what I’ve seen

Honestly for the last couple years the best model has been the Panic Room thread.  Basically just get your winter weather forecast from there and it's been pretty accurate.  No fancy models needed.

Real question: What good are the weeklies? Isn't that like...impossibly far out?

They're good for looking at the northern hemisphere and how things could evolve. When I look at the weeklies above it makes a lot sense to me. Epo ridge still there but higher heights/pressure squeezing back into the NAO region. So the idea of blocking flexing after the TPV does the do-si-do around the pole and heads south again. Adds some confidence to my thoughts earlier about how we move thru the month. 

What the weeklies aren't good for is snowfall/storms or anything specific. I only use them to know whether to close my blinds or not. Right now they remain open.

We know it is going to rain tomorrow and Saturday.  Until these two storms clear the field I think it is very difficult trying to figure out next week.  Sunday- Monday will be interesting to watch the model runs.

We shit the blinds for 7 days as we reload and regroup. Plenty of time still and no shortage of chances.

Unfortunately not happening with that MJO phase 4 wave. The pacific ocean has been really cutting our winters short the last 4 years with a pacific firehouse, -PNA and the MJ0 lag in the MC. 

Meh, MJO impact is overrated. We’ve seen too many phase 8-1’s fail and phase 4-5 succeed to believe it’s somehow the end all be all for our chances to get snow. A factor? Sure. One of a many. But the MJO is always so overblown on this forum.

I've been wondering about that. How are we getting the polar vortex to swing through during a strong phase 4?

The same models runs that predict the mjo also predicted that look. You can’t separate one from the other. You’re choosing to believe the mjo forecast but not the rest of the output from the same run!  Cherry picking. Besides the mjo is out of phase 4 by around Jan 17th.  The mjo is likely why the guidance has a temporary breakdown of the pattern around Jan 22-28th. That’s the lag. 
 

A hostile mjo wave in mid January won’t cause February to be bad. Maybe Feb won’t be good but it won’t be because of what the mjo was on Jan 13-17th!   It’s actually so ridiculous I honestly wonder if you’re trolling.

Precip/waves aren’t our issue. We do that generally well. It’s either cold enough or it's not…simple as that. I’m all in on tracking blocking. Without that, it’s a struggle to even get a clipper.

Doesn’t look like much, but won’t take much to create a follow up wave along that boundary either

That looks like a clear arctic boundary on the models. Some of our biggest snowstorms love to develop along arctic boundaries.   That is a very stout 1051 mb high building south out of western Montana diving down to Texas and Louisanna that will really raise the heights along the East Coast maybe we can get something to develop near Jacksonville Florida or the NE Gulf to move up the coast. 

We likely will know very little until the cutters and the baroclinic zone they leave behind decide what to do in regard to the next cold push and storm development.
