6Z para shifts the main snow risk to the Midlands and Wales

 

 

Op run not really interested although does give a dusting to Wales and the north Midlands.

 

Sunday's snow risk is creeping up on the GEFS, though, with 25% of runs now showing snow for London:

Sunday looking more prone for snow in the south on the GFSP. This will change to the 6Z shortly but some lying snow showing up for central southern parts, Chilterns etc.

The stronger the ridging from the American side across the Arctic keeping the low heights over the pole from phasing with the Canadian low heights the stronger the ridging will be inthe Atlantic. Which should lead to better amplification and synoptics down the line.

First up again is the Icon. I wonder if we will see any improvement on the 06z run.

Some slight interest again for cold weather fans but sadly I think the jet will scupper our chances of anything decent.

To be honest with the exception of a brief cold(er) blip on Sunday/Monday I’m not see too much of interest from a winter fan’s viewpoint.

I'll keep looking and searching like I did last year, at least until it becomes pointless to do so.

Well the colder blip is colder than was expected in what was going to be part of a bigger milder spell and it only took about three days to become so. I guess after that we have to now accept a mild week but there is still two more (almost,but shrinking fast) weeks of February left. I have resigned myself to the fact that this winter will not however be remembered for any long or severe cold spells. Not quite a winter's over post and I might as well wait till the end of February now and do it properly.

Monster block on 18z setting up for same time as last year! Something to watch

40% of the GFS purtabations show a cold outcome in FI, but the scatter of scenarios is as manic as ever.  However the jet scenarios seem to be as unpredictable beyond 120 hours, so it's no wonder.  The SW event  seem to expand the scatter as the models struggled to get to grips with it...but not faring better now frankly.

ECMWF is hinting at a block happening earlier than the GFS.

i am getting interested. 1978' late feb blizzards in the SW - But I had 2" in Sussex then & was most grateful. The beast proved it's never too late until Mid April at least!!

of course early March is the latest I've seen lasting snow in lowland uk in the south.

This winter is actually very similar so far to that of 2012/13 except December is milder this year. but in terms of the SSW it's fairly similar to the weather pattern we had in Jan 2013. SSW occurred early Jan 2013 and we had cold weather around the 3rd week of Jan 2013 and Feb 2013 was milder for a time with an increase in westerlies and I remember some short lived northerlies with the HP trying to move northwards but kept of failing until end of Feb 2013 when it became drier and heights rose to our north and then the real cold with HLBing came in March 2013 and that lasted right through until early April. Where as this Jan 2019 we have had the SSW & split of PV at a similar time to that of during the winter of 2012/13 (give or take a few days) and we have had some cold weather in 3rd and 4th week of Jan 2019! Not identical of course but similar to that of Jan 2013 because if I rightly remember the cold and snow we got in Jan 2013 was not cause by much in the way of HLB. 

Notice back in Jan 2013 we had southerly tracking lows!?

 

After a battle we never really got exceptionally cold in Jan 2013 and after a battle Jan 2013 ended mild and wet with long fetched south westerly wind which is what we are and will be experiencing more of soon and a strengthened Azores high and LP over Greenland:

--------------------------------------------------------------------------------------------

Jan 2019:

Seeing as the weather pattern has been similar to that of Jan 2013 - could we see a repeat of March 2013? i.e blocking never really getting going until end of Feb and March comes the bitterly cold easterly? It does look unlikely but never know!? just trying to be optimistic is such dire times weather wise and politically!
