t¦nt¦n GFS going for a greenland high ?

To get blocking you need heights to transfer like shown to shut off the Atlantic.
Or a Scandi linking up




Unfortunately it not going to happen.

Boooo to youuuu

I likes this run!
Its a bit better than a just brief cold snap on previous runs so could bring down temps before the potential snow system comes along !






Opinions folks?

I think the two HP systems have linked up on the 18z , I have just posted in the model thread 0-7 days
Just noticed mine was from the 29th not 2nd
Also why would you say it wont happen ?

I'm looking for this when i say heights rises.



As you can see from what happened last November,twas a beauty.
She shut down the Atlantic and opened up the door to the great white Siberian army

The Jet Stream got bent like an S hook.:D






As regard to no blocking well Teleconnections not wonderful at the moment,however the New Year really could be interesting as pointed out already by M.T

Im waiting for the QBO easterly phase to get stronger (More Negative).
I've highlighted the important bit in image as we are in La Nina.





Anyway the Weather make it's own mind up.:)


Although US focused this next little piece is interesting as this person describes


"Following closely on HDD (ed: heating degree days) measures of the two previous winters, the 2011-2012 season will have similar stretches of bitterly cold weather. Both the West and Dixie regions look to get occasional breaks from the cAk regime.
"It is the Midwest that will have the most issues with unrelenting presence of frigid air. January looks to be the key month for HDDs."

Dominated by strong 500MB ridges in the -EPO, -AO, and -NAO positions, intrusions of bitterly cold (cAk) values look to be common during the upcoming winter. In terms of temperature, the Great Plains and Midwest will suffer the most, while Texas and the Dixie states may get some breaks from the harsh domain in December and February.
"The strongest storms will be those which occur just ahead of the frigid regimes, in the "Colorado/Trinidad" and "Panhandle Hooker" trajectories. Alberta Clipper systems may appear with some frequency as well (accounting for a major lake effect snowfall pattern in November, December and early January.

i have no idea of what i read there but its looks good

Something I'm not entirely sure about, the Greenland chart you posted above has SLP of 1035hPa over Greenland which is obviously high yet its not really classed as a high.

Is this just a 'shallow' surface high and what we need is for the high pressure to rise to the upper atmosphere?

Charts showing a bit of cold from the 30-6th all subject to change on the next run



To me looks like a blocking high but my limited knowledge I could miles off :cool:

-8 uppers if only it would happen

Models seem to be showing cold on and off the last few days for the 5th December. Must be picking up on something out there.

Heard on TodayFM this morning the winter freeze is going to start on the 4th December ! Maybe in FI...

WolfeIRE

UKMO not indicating anything significant for the UK
The generally unsettled theme looks set to continue through the early to middle part of December, with spells of wet and windy weather separated by some drier interludes. Temperatures will be largely around average, perhaps becoming slightly above average, by mid-December. However, some colder spells are still to be expected at times. Even with average or slightly above average temperatures, frosts are still likely, particularly on the clearer and more settled nights. Rainfall amounts will be around average, with the wettest weather likely across western parts and some snow probable over the higher ground of northern UK, particularly during the colder spells. Sunshine amounts are also likely to be around or slightly above average in this rather changeable regime.

The good thing about FI is that even though at the moment things look depressing after a couple of days they may change again to make us all excited and unrealistic again.

GO PURPLE IRELAND!!
