Pattern January 2021 - Joyless January

Wouldn't that beat down any chance at ridging on the west coast? @Webberweather53

I think mountain torque events result in increased meridional flow, so there would be more extreme troughs/ridging. A +EAMT event in particular I believe would promote a +PNA, but I'm not going to try to explain since I'm sure Webb could do it better than I could ever hope to.
 
Didn’t a similar thing happen late December 2017 ? @Webberweather53
This year there definitely way more pronounced troughing around the Bering sea/Aleutians popping up, which arguably could put more strain and anger the PV even more
This year there’s also significant blocking in the mix, so in some ways it’s quite different than that year BDBCE3CF-B62B-47AC-9A75-7CAD662D7804.gif320A6CA6-AB40-4CFA-8491-11EE6F28A1DB.png

Yeah this is very different imo, suggests much better pattern potentially in the latter stages of winter unlike 2017-18 which went warm after early Feb until march

The complaining in here and other non-whamby threads, is overdone imo considering we’ve had the coldest start to winter in years. Also, the amount of complaining in these non-whamby threads is ironic considering the criticism that @ryan1234 was receiving recently for just trying to be realistic about the chances for snow in NC around Christmas. Double standard. All he was doing was trying to be realistic to minimize the chance of the later complaining.

Absolutely, the start to winter has been great! If people don’t like this they probably need to move north to satisfy their winter desires. We are now heading into our prime time to score a snow storm.

As a LaNina that would be very similar to 1993-94. After an active and cold period from just before Christmas to just after New Year’s, we had that Arctic Outbreak during the middle of January along with an significant Ice Storm. After that we continued to get cold shots and then of course there was the big ice storm for a lot of the south in mid February.

Seems like every time we get -EPO blocks tho we risk the Southeast ridge, we seem to lose everytime with the -EPO all or nothing pattern, I know a +EPO/+WPO/-AO/-NAO pattern sucks for cold with storms but at least the southeast ridge is suppressed with those indices like that 8C63E7AA-4E66-4B82-BB8D-6151C4357DBF.png80A5BEF2-6866-4EAD-9766-0286467FE547.png

The GEPS just doesn't let up through first third of Jan.. If the south can't score some snow during this upcoming period, then cancel Winter, I guess. ;)

You know with the severe weather forecasted on Thursday, it reminded me that the last time I can remember seeing severe weather on Christmas Eve or Christmas Day was 1987. Then of course 2 weeks later...
