Winter 2013-14 Pattern Discussion II

Recommended Posts

Euro has been the one that has hyped a couple of snow storms here already this winter while the GFS was more realistic and was the one saying no. I think GFS hyped one in the long range, but the Euro has done it a few times and it turned out wrong.

GFS wasn't even seeing the cold long enough to get a winter storm. If that model was actually cold instead of popping a ridge on Jan 7th, we probably would have seen some fantasy storm materializing in the LR back around Christmas. It was more realistic because it was WRONG about the cold. You can't get fantasy snowstorms with a SE ridge in the LR. Have you noticed it's actually seeing cold in the LR now and giving us some snow chances in the LR mid-month?

12z Euro Ensemble

Days 5-9: +EPO below normal heights in Alaska, western U.S. trough, above normal heights in the east, NAO neutral to positive

Days 10-15: Ridging builds off the west and east coasts, central U.S. trough progresses into the eastern U.S, NAO neutral to positive

PV located north of Hudson Bay Days 7-15

 

12z GFS Ensemble looks similar but it doesn't build as much of a western trough in days 5-9, and it brings the western ridging inland along the west coast late in the period (+PNA)

 

Looking at 850mb temperature anomalies, days 5-9 are above normal, days 10-15 transitioning to normal, then below normal

 

Only thing that stands out in terms of possible wintry precip from a pattern standpoint would be clipper type systems / northern stream divers if the ridges off the west and east coasts were to extend more poleward in the 10-15 day period.

Talking about how many storms they have showed only to lose them. Used to be euro automatic under ten days. Not this year

The models have been showing warm-ups and colder air this year and have not gotten it right. Now did they show a warm up in DEC sure but they showed a warm up all month and it came for a small 5 day period. Cold air is on its way the models latched onto this about a week ago , now it's on it's way , but we will see if its -10 or colder as modeled 10 days ago. Problem is the models are doing such extreme solutions that either way they can't be believed or trusted . This past year the models have been unreliable until 3 days out.

It looks more and more likely this winter will be solidly a +NAO winter, which spells doom for us.

Not  too optimistic either.  Long term patterns are hard to break.  I will say that in 92/93, I remember being frustrated that not much had happened and it seemed most of the action was just to our north.  Then, we had "the storm".

If we could just have one big storm it would make up for everything else sucking this winter. Just like the two snows in late Jan 2000, with the second one being the Carolina Crusher. But we said the same thing the previous two winters. You would think with all the cold and precip we have had that they have to meet up sometime.

Without a consistent -NAO, we are stuck with timing to get a Winter storm.  Depending on timing is like buying lottery tickets;  More times than not, you lose.

It's why Franklin mentioned a southern stream earlier. Getting that going at some point will help very, very much by widening the timing window.

We missed out on the Carolina Crusher in Surry Co.but we had 3 other storms during the 2 week period in Jan 2000 so I was pleased with that. Does anyone kniw what happened to cause winter to start that Jan nd what caused it to end so quickly?

Well, we've had it. Just can't get cold when it matters.

I don't think we've had too much of a true southern stream yet. We've had the northern stream drop plenty of energy in the SW and cut off and or a piece of it get left behind and then come out and of course cut to the north. Energy coming in through southern California and tracking along the Gulf coast and off the southeast has been nowhere to be found so far. We get that going, with all the cold highs we've seen, and we'll be in business. :)
