MJO812 Posted November 24, 2020 Share Posted November 24, 2020 December looks like it will start off with a bang if the models are correct. Huge PNA ridge with a possible negative NAO. Subject to change . Link to comment Share on other sites More sharing options...

After the 1 week of December I believe are chances of a snowstorm will be higher. The one around the 5/6th is our first chance. 2 Link to comment Share on other sites More sharing options...
wdrag Posted November 25, 2020 Share Posted November 25, 2020 Just a note... I see the EC and GGEM op runs from 00z/25 are favoring another event for our area around the 4th-5th. Have my doubts if the first storm around Dec 1 is big. Too soon too recover except for a CFP. EPS has not much hint, though-some, and GEFS is all nw flow at 850MB after Dec 1 for a week. Instead we may need to think about Dec 8-9. That looks a little more promising to me, including a weeks recovery time. However, I hope for nw suburbs folks, to be wrong about Dec 4-5. 1 Link to comment Share on other sites More sharing options...

CIK62 Posted November 25, 2020 Share Posted November 25, 2020 CMC is 7" on Dec. 04. Real issue is how many hurricanes is it showing at that time! Lol. CMC has lost all our Snow on latest run (12Z) and now has snow down to Florida. (Route 95, anyone?) Still looking for those ubiquitous CMC TC's. Lol x 2!

The current Niño-like +PNA to start December appears to be related to the MJO in the Indian Ocean. So a shift over to the Maritime continent could mean milder conditions by mid-December with the lag. Could make the end of December and January colder if it continues into the colder phases. 3 Link to comment Share on other sites More sharing options...

It's going to take a few days for that to be sorted out. I'd still go with the phased solution rather than whatever the gfs is doing. One thing I'll be keeping an eye on in the ensembles is whether or not the PNA ridge rolls over or not. If it does then we'll warm very quickly by mid December. 1 Link to comment Share on other sites More sharing options...

TriPol Posted November 25, 2020 Share Posted November 25, 2020 We haven't had a good snowstorm in early December in a long time. Wouldn't be a bad time to try again. I fondly remember the blizzards of 2000 and 2003. 1 Link to comment Share on other sites More sharing options...

The current Niño-like +PNA to start December appears to be related to the MJO in the Indian Ocean. So a shift over to the Maritime continent could mean milder conditions by mid-December with the lag. If this is correct, then mid-late December turns mild. I believe December, 1988 (also a strong La Niña) had a +PNA run from 12/1 - 12/15 before it flipped. The late November strengthening period for this Niña has begun in earnest, the easterlies are really ripping right now and are projected to continue to do so well into December. Regions 3.4 and 4 are about to see another big SST drop from the upwelling. This is going to really limit how far MJO waves can propagate before they get sheared apart by the very strong easterlies and run into the colder waters....which is why MJO phases 3-6 are favored this winter Link to comment Share on other sites More sharing options...
