WEATHER53 Posted November 27 Share Posted November 27 Arctic outbreak is music to my ears. This is not roll over and roll out cold. Its down and upon us for like 4 days of -15 departures. Meanwhile Mongolia getting ready to distribute more . We have not had back to back below average months for 18 months so maybe this is the beginning of that 4 1 Link to comment Share on other sites More sharing options...

And more than one clipper too. TBD whether the precip makes it over the mountains and gives us some light snow. 6 Link to comment Share on other sites More sharing options...
yoda Posted November 27 Share Posted November 27 It's the 12z CMC at the end of its run, but I'd like to think it was getting ready for something good after 240 looking at SLP/HP placement and h5... I think lol 2 Link to comment Share on other sites More sharing options...

I think lol Yeah it looked good. Gfs is a parade of northern stream clippers that all manage to barely screw us lol. Either way, all showing potential by late next week and beyond. 9 Link to comment Share on other sites More sharing options...

There are reasons to be encouraged obviously. We need anomalously cold air in the first half of December to even have a chance. But this could be the winteriest December in years for our area and we could still end up with 2-4” of snow total… 4 4 1 1 Link to comment Share on other sites More sharing options...

WxUSAF Posted November 27 Share Posted November 27 6 minutes ago, Eskimo Joe said: Oh yea baby Yeah that looks nice. GEFS pretty similar, just less intense in the height anomalies. Both show us BN for the duration and precip bumps up starting late next week. 21 1 Link to comment Share on other sites More sharing options...

Stormchaserchuck1 Posted November 28 Share Posted November 28 18z GEFS really shifted away from last nights modeling of -EPO/+PNA in the medium-long range. Now it shows a Gulf of Alaska/Aleutian High pressure. Although the pattern may be getting wetter after Day 10, it may just be rain. 2 1 Link to comment Share on other sites More sharing options...

Not surprised really. That solution is clearly viable. Let's see how the other's and it do the next couple days before presuming we're headed that way though.

We may moderate back to NN or somewhat AN for a period of time around the 12th or so, but things may get interesting again once we get to 7/8 (maybe late dec or early jan) with a colder airmass the second time around. Still watching the clippers and the 12/8-10 window. 2 1 Link to comment Share on other sites More sharing options...

Blizzard of 93 Posted November 28 Share Posted November 28 The 3 main global ensembles at 12z still maintain a favorable look in the day 10 to 15 period. 3 Link to comment Share on other sites More sharing options...

Blizzard of 93 Posted November 28 Share Posted November 28 The 18z GEFS has brief transient ridging in the east on day 12/13, but then quickly evolves back into a more favorable look by day 15. Temperatures at day 15 are below normal as well. 3 Link to comment Share on other sites More sharing options...

NAO is positive, and it's close in the Pacific to a -PNA. 2 Link to comment Share on other sites More sharing options...

Any "rug pull" wouldn't be anything we haven't seen before. Now may be the perfect time to step back and let it play out...(Or at least, that's what I TRY to do, though I keep breaking my rule and turning off my site blocker app and coming in here sometimes).
