January Medium/Long Range: A snowy January ahead?

Recommended Posts

Fwiw, Gefs latest Extended puts a weak MJO wave into Phase 8 by February 20th. That's an excellent phase for us in a Niña with a trough in the east.  Coincidentally, it matches approximately the period Psu highlighted for a return to cold per analogs.

See how simple this is? :weenie:  Lol

I was just thinking about this when bluewave kept mentioning the stronger pac jet. 

We saw the same last year when the pac jet verified stronger than forecast, and that actually hurt us in a nino by flooding the continent with mild pacific air almost the whole winter. Only when it relaxed a bit did we get a snowy week in Jan here.

Now this time, the stronger pac jet is helping us because were not in a nino (cold enso/weak nina). In the long range, the models keep trying to weaken the jet and bring the PNA ridge west towards the aleutians. Then it all shifts east as it gets closer in time. 

Thanks for that explanation since the stronger pacific jet has been bad for us the past several years.

There are some misconceptions about this and what is 'good' or 'bad'. It isn't that simple. There are also 2 Pacific Jets- The NPAC jet is a part of the Polar Jetstream, and what is often referred to as simply the Pacific jet is part of the Subtropical jet. (there is both a Polar and a subtropical jet in each hemisphere) The STJ is usually quite weak/retracted in a Nina while the Polar jet is predominant, and in a Nino the STJ becomes more prominent and tends to be extended and located further south. That's what gives us the active storm track across the southern US. There are also 'degrees' of retraction/extension with both jets. In general a jet with an extended core of stronger winds favors a ridge in the western US (+PNA), and retractions favor a -PNA.

Nah, follow up is rain too.

Not so sure I buy the warm scenarios yet.

Key is getting out that s/w quicker than what the GFS shows I think.  Gotta get it to us before the cold retreats.   We might be finished for a bit, but I'm not even close to being down.

Hard to be mad, but if we just had more typical below avg temps this week with the true arctic cold/ HP just to our north, we would have been getting the snow instead of the deep deep south.

If the board got together and financed a trip, would you fly out west and kicked that s/w out?
