Early December Pattern Discussion


Baroclinic Zone

Recommended Posts

Weeklies much better. Near normal temps week 2 at 850. Week 3 has about -0.5C below normal at 850. Week 4 is about +0.5C above normal at 850.

Big +AO, but some ridging in the PAC trying to push back the se ridge.

Latest weeklies right?

I'm sure its almost the exact same thing for me. Is there a strong temp. gradient? Whats the temperature anomaly out West?

I dont think the +AO is going to weaken so quickly. Stratosphere does show very slight warming the near future but clearly the pattern doesnt support decent blocking, not yet. I still think we'll see a decent pattern change between Jan 5th-10th, give or take a few days earlier/later.

It's cold out west and into the nrn Plains. The anomalies are aligned sw-ne. It think it means we ride the line with storms. Some would west, some maybe just to our south.

The cold is starting to over perform. 17/39 today here despite mild 850's and already down to 25. Only one day this week (Thursday) could even approach a torch and nothing compared to past mild wx.

We knew that warm BS last week was wrong. What a flip. Almost like when they have Novie cold and then suddenly flipped warm. Weenies..we have some winter wx to start tracking as we move into next week

Without decent blocking the pattern is fairly progessive so I dont think we'll see strong storms but nice gradient type storms like 07-08 and 08-09 had.

Thanks!

This is the THIRD december in a row where I've been shafted or done horrible in, how sad. 4th is likely after Dec 31st, haha.

Strong Easterlies continue across the Nina regions....we need to get that blocking in soon, lol.

Seems to agree with the Euro ensembles day 11-15?

Yeah not too far from it.

I feel like I need to see some more model runs in order to make me feel a little more optimistic. The 00z runs and 12z runs could really bring it back down into the gutter. I think it looks a little better, but I would like to see more evidence in the form of model runs that continue the trend.

I was out there in Hamilton for work (stayed in Oakville) and no snowcover...quite a bit of green grass yet...nasty. It did flurry...

Rick, its amazing how chilly its felt the last 3 days, today included, hard to believe all 4 sne climo sites were AOA normal today but the +6 at ORH is a heck of a lot better than the +20's, slowly sinking to climo which should bottom out in another 4-5 weeks.

Yeah I have no idea what climo would be right here in these hills, but chances are if the weeklies verified near or even 1 or 2 C above average, we would get some snow events in there...one would think. I'm more "pro snow" than "pro cold"...don't care if a week averages several degrees above normal if I get a snowstorm.

Just busted out a 10-pager in a few hours. It's nice to be a senior and not care anymore.

But back on topic, some nice trends on guidance today. 12z EURO looked decent. At least we have a couple threats out there. Whether they track ideally (thread the needle) or go OTS or west remain to be seen. At least we got something to watch for.

The pattern still overall remains junk, but basic climo along with a slight relaxation in the PAC jet with more ridging out there might give us a couple shots between now and Christmas.

So far its more of a pattern getting better only because it really couldn't get much worse.
