Quiet in here tonight


Just a hint of something more interesting in the GFS ens this evening:-



Falls roughly where the MetO forecasts are going for a quieter colder interlude so something to keep an eye on I guess.


Before then mobile, wet, windy with some wintry interludes for Scotland and maybe Northern England at times too. Looks significantly wet for the North West of the UK too, which won't be welcome.


Judging by the chart above they'll be some mild days down here but it's generally average by day but I suspect with warmer than average nights due to cloud and wind rather than 850's.

Same story all winter, and as you say yet more rain for the north west http://modeles2.meteociel.fr/modeles_gfs/runs/2016013112/240-777UK.GIF?31-12 


Though at least they have had some "weather"  in he north this winter with wind/rain and the odd bit of snow.  Imby it's been just one long ZZZZZZZ. Can only signal 1 day this winter with any notable weather, got don to -5C in the last so called cold spell in mid January.

Disappointing runs today. Added to Ferguson's latest thoughts it does seem the Meto are backing off their original prediction of a back loaded winter. Even the cold zonality is not looking that cold anymore as Imogen looks like staying to the west of Scotland. Perhaps an SSW might rescue things but it does appear another war is nearly over and we lost again

What will this named storm be then? 955mb? - Gosh far from settled even as we approach middle of Feb - at least some decent snow for Scottish ski resorts and Iceland doing well.

Some pretty decent looking runs on the 18z ensembles so the Op will certainly be in the pack tonight and expect the mean to 850hPAs to head south of -5 for large parts of the U.K.

Not quite as good as I thought but nine or ten runs hit circa -8 850hPA for large parts of the country and the Op and Control are two of the coldest!

Winter Model watching fatigue starting to really set in here... ill plod on though.

Teh GFS keeps throwing up tempting features in FI, to be moderated as time closes in. GEFS reflects this picture nicely as a fairly mundane but cool and occasionally briefly cold theme showing a consistently horizontal picture.

However.... one or two members have gone rogue recently, which goes againts this fairly steady grouping weve seen over the past few days. I hope and pray its starting to smell something.

ECM 12z ensemble for London:


http://www.weathercast.co.uk/services/ensemble-forecast.html


 



Good agreement of the general theme for the coming week.  The Op was in the mildest options for days 8-9 and still above the mean for day 10.  Beyond Day 10 the two main clusters offer average or cold conditions, leaving the mean a little below normal.  Very few mild options in the mix, even towards the end of the run.

Very good performance by the NWP in the last 10 days. Mobile with a sinking jet and an increasing chance of a major wind event. The significant storm today affecting Scotland will likely be repeated several times in the outlook period and affect more of the UK.


Forget widespread cold and snow - that will not be the headline maker this week.

GFS still going with the St Valentines BBQ in FI, indeed the chart for the 16th could bring 17c to London.


This IMO is a likely outcome and I am going for shirt sleeves in mid February rather than gloves and snowballs with a 1998 re run.


The only atmospheric analogy for winter 2015/16 is 1997/98 and for that reason i never brought the back loaded winter thing and the MetO now water it down with every update, meanwhile it's another grim day up north with a gale force westerly wind 11c and more rain.

Obviously the models are struggling but the strong Nino footprint is leading  all other teleconnections the merry dance and I think we'll see a watering down of any colder anti cyclonic weather as we move through February.
