Tonight's Ecm 12z adds to the blocked anticyclonic outlook with the Atlantic threat snuffed out. I noticed earlier the MO mention Atlantic systems would continue to push into the far northwest but clearly they won't if the Gfs and ecm runs are near the mark, a big blocking scandi high will see to that, temperatures look pleasant, somewhere in the low teens Celsius by day but chilly nights and it would turn colder from the continent in the southeast later if the ecm is correct.

A thing of beauty....

 

Were this January and were Britain and Europe snow covered, this would be utopia for cold fans in the SE.

 

Snow? I see nothing there that would produce snow, pressures to high, no instability, nothing to produce precipitation.

On the other hand it would be great for summer heat! :)

The ECM mean is supportive of a change to a dry and fairly mild spell developing by next weekend. How chilly any easterly gets will depend on how far west the colder air manages to reach as it battles against mild air from the south. Despite winds set to come from the same direction as late March 2013 crucially its the source of the air that will make the difference this time. The GFS shows temperatures remaining mostly in double figures.

Tonight's Ecm 12z ensemble mean turns very blocked with a powerful scandi high becoming the dominant feature as far as the uk is concerned, it's goodbye to the Atlantic for possibly a couple of weeks beyond T+168..it won't be missed by me.

I hope a few of us keep the model output discussion alive despite the mass exodus. :-)

18z shows high pressure building in across the south of the UK during midweek but with a slight delay further north as one final low takes a swipe at northwestern Britain which is where most of the rain and wind will be next week but beyond that it's a rapidly improving picture with high pressure intensifying and migrating to scandinavia creating a robust blocking anticyclone which once established, lasts over a week before any signs of a breakdown. The general weather would be fine with sunny periods and temperatures of 12-14 c but the 18z shows winds going around to easterly and briefly drawing air from eastern Europe before backing more southerly with much milder air pumping up from southern Europe. It's looking good in my opinion, much nicer than that Atlantic dross we had for most of the winter and start of spring.

Finally, we have arrived where the NWP agrees the high anomoly will make it to scandi. Some rather tasty NH profiles abound in fi GEFS. Shame it's march but I guess that has a lot to do with it. those expecting mid march warmth may be frustrated although it wouldn't take much of a shift in the predicted pattern to bring warmer southerlies than the cool soueasters currently shown.

Well the GFS this morning shows the perfect phase 7 to 8 transition

gfs-0-240.png?0

gfs-0-300.png?0

gfs-0-360.png?0

Retrogression of heights towards Greenland. Just nice to see how a model to cleanly show this happening. It probably won't in reality though.

 

All the models show a cold pool moving towards the UK with the winds swinging easterly, now this is a cloudier scenario with a lot of stratus moving in from the north sea, it would be nicer to keep a warmer flow with a south of east vector to the wind as that will allow sunshine to be widespread across the UK, the exception probably being the north east coasts in that respect.

GEM the flatest at day 7, but still pulls in an easterly later.

Excellent support for the south to be within a higher pressure scenario till around D15 with the spread highlighting that:

 

D10: post-14819-0-94416500-1425714194_thumb.p D15: post-14819-0-65323000-1425714190_thumb.p

 

Not completely dry in the SE, but significantly wetter the further NW you travel. Next 8 days GFS totals:

 

post-14819-0-52915500-1425714349_thumb.g  Temps London: post-14819-0-63929200-1425714391_thumb.g

 

Temps are 1-2c above average in week 1 and 2-3c above average in week 2 (mean), so no sign of cold apart from the GFS op (and that is best to ignore at the moment due to it's known bias).

 

What happens around D11-12 when the core heights, then over Scandi, retrogresses to the UK is what the GEFS are currently divided. The Op links to Greenland but has only small cluster support, though control in the same ball park. HP remains the main theme for all the GEFS in that fluid modelling period. The clustering around D12 highlight that:

 

post-14819-0-80764500-1425714815_thumb.p

 

So any Scandi high looks transient on the GEFS. We should see the other models coming into that range by Monday but D10 charts for comparison:

 

post-14819-0-13308000-1425715036_thumb.gpost-14819-0-13254000-1425715038_thumb.ppost-14819-0-24119600-1425715065_thumb.p

 

Quite good inter and cross model support for the general pattern in the next 10-12 days, but afterwards where the core heights go is clearly not resolved yet.

Easterlies bring in alot of cloud in Spring for eastern/central areas, shocked nobody has mentioned this.

 

i have old chap.... several times, the stratus-fest that suits no one (surely no one likes that?)

 

and this mornings models strongly point to at least a short lived easterly spell if not longer. once established they are very hard to shift. the ecm @ t240 (00z) suggests something quite bitter

 

post-2797-0-77229000-1425714640_thumb.gi

 

but thats probably the most extreme version of what might occur.

 

the gfs (00z) @ t240

 

post-2797-0-59963200-1425714719_thumb.gi

another 'vote' for a scandinavian block, but orientated so as to bring southeasterlies, not as cold, but still rather cloudy?  even off a dry continent...

the anomalies for c t240

 

post-2797-0-47670000-1425714903_thumb.gi .... support what their respective op's predict... but

 

post-2797-0-14974300-1425714947_thumb.gi the noaa doesnt agree with either.... so without consistent agreement all that can be gleamed is that there likely to be high pressure somewhere to our northeast - east.

but with the follow up high pressure that was supposed to build behind tomorrows cold front failing to build, allowing low pressure in on monday, and the apparent failure of pressure rise behind that to establish a settled spell as predicted 24 hours ago - (there is, this morning, another atlantic system appeared for wednesday) then theres great uncertainty even as close as 4 days.

post-2797-0-63163500-1425715414_thumb.gi.

to me its looking like its deteriorating into a more unsettled regime, with expected pressure rises being restricted to 24 hour ridges. the noaa 8-14 dayer would be more in line with a more mobile pattern?... (or is that wishful thinking? lol)

edit.... just seen ido's post which kind of suggests the opposite to what ive just posted.... great this model watching isnt it? the way different people can interpret things differently :) its all good.

Rob - the anomolys you posted (EC and GFS nxt to each other) are the 6/10 day mean representation of the op runs. That's WHY they support the ops! I have been trying to get this over for years - they are not mean in the sense of ens - they are mean in the sense that they average out the 5 day perod of the operational run.

If the op run fi is guff then so are those charts.

And I think IDO is closer to the mark re what the nwp currenly shows than your less settled thoughts.

Cheers for that.

Indeed ido might well be proven closer to the mark, but as its not a competition i dont care! Its the way these two troughs have appeared out of nothing that caught my eye, at the expense of previously predicted high pressure build. That suggests short term uncertainty? Anyway, time will tell.

  • Location: Kilmersdon Radstock Somerset
HERE IS MY LATEST ANALYSIS USING DATA SUPPLIED BY THE NWP OUTPUT COVERING 5 OF THE WORLDS MOST POWERFUL WEATHER COMPUTERS ISSUED AT 08:00 ON SATURDAY MARCH 7TH 2015.

 

THE CURRENT GENERAL SITUATION A slow moving cold front near NW Scotland with a mild SW flow ahead of it will move SE down across the UK tonight and tomorrow.

 


 

MODELS-2 WEEK HEADLINE A lot of dry weather with some sunshine and just occasional rain. Temperatures will be close to average but possibly colder later.

 

THE GFS JET STREAM ENSEMBLE FORECAST The Jet Stream Ensemble Forecast shows the flow increasingly blowing SW to NE over the North of the UK or between Scotland and Iceland. With time the flow's axis moves further to the NW still, probably near Iceland before breaking down into smaller eddies later with a stronger Southern arm near Spain for a time.

 


 

GFS OPERATIONAL The GFS operational today has taken a new route today as the underlying trend after next weeks rather changeable weather under occasional weakening troughs crossing the UK from the West is to build High pressure to the NE of the UK with SE winds developing across the UK. These relatively mild at first with occasional rain to the SW will gradually turn colder later as the High retreats West and North from Scandinavia to the Greenland area with cold and perhaps wintry weather knocking on the door of the UK from the North and NE later.

 


 


 

THE GFS CONTROL The GFS control run follows a similar route with rather changeable conditions over the UK over the first week before pressure builds to the North and NE with an ever increasing threat of much colder and more unsettled conditions over the UK against cold Arctic origin air lying near to, over or to the North of the UK late in the period.

 

THE GFS CLUSTERS Despite the two runs from GFS above the clusters show a more likely option being High pressure to the South with westerly winds and rain at times the most likely scenario at 14 days with other options indicating High pressure closer in towards the UK with dry and fine weather for many with only a 5% section of options showing the cold Arctic air down across the UK at the end of the period.

 


 

UKMO UKMO this morning shows transitory High pressure crossing East over the South at times interspersed by troughs of Low pressure crossing West to East midweek over the UK with rain at times.

 


 

THE FAX CHARTS The Fax Charts show changeable conditions too next week alternating between High pressure with fine and chilly periods and cloudier windier spells with some rain for all as troughs cross east over the UK towards midweek.

 


 

GEM GEM today shows the same changeable theme that all models show over the next 5-6 days with some rain at times between drier and fine spells. It then takes High pressure across to Europe with an ESE flow developing across the UK with an ever threatening chance of rain affecting the far South by day 10.

 


 

NAVGEM NAVGEM too shows High pressure shifting further east later next week and into the weekend with the sane fronts crossing East on occasion through next week delivering a little rain before things settle down later under a ridge extending West from a German High over Southern and Eastern Britain.

 


 

ECM ECM this morning is all systems go for a change in pressure pattern later next week. High pressure is shown to shift location from close to Southern Britain to a point North and NE of the UK with the weeks changeable weather under a Westerly flow changing to a brisk and probably chilly Easterly with occasional rain and showers over Southern England and Wales later

 


 

ECM 10 DAY MEAN The 10 Day Mean Chart shows that the Easterly flow shown by the operational this morning has grown a lot of support over the last few runs with the majority of ensemble members now showing High pressure to the NE and an Easterly flow of one sort or another over the UK in 10 days.

 


 

NOTABLE TREND CHANGES FROM PREVIOUS RUNS The main difference in output this morning is the much increased trend to build High pressure to the North and NE of the UK after next week with a variety of implications that this pattern may give.

 

31 DAY HISTORICAL VERIFICATION STATS FOR GFS, UKM & ECM The current verification statistics for the past 31 days shows ECM leading the way at 3 days with 97.6 pts followed by UKM at 97.2 pts and GFS at 96.4. At 5 days ECM  continues to lead the field at 90.2 pts over UKMO at 88.7 pts and GFS at 86.6. At 8 days ECM remains the leader with 67.1 pts over GFS's 60.0 pts. Then at Day 10 ECM retains superiority at 50.0 pts over GFS at 42.9. 

 


 


 


 


 

 

MY THOUGHTS High pressure remains the driving force of the weather across the UK over the next two weeks but there has been quite a shift in emphasis to the longer term positioning of this feature. Through the coming week the pattern remains as before with High pressure close to the South of England with spells of fine and dry weather interrupted on occasion with a stronger Westerly breeze and occasional rain from eastward moving troughs. Then later next week a more concerted and nationwide development of High pressure settles things down with fine days but some night frosts in places. It's from that point on that the positioning of the High further to the North and NE of the UK has a more direct effect on the conditions across the UK. In the first days of this pattern it looks like temperatures will stay largely close to average or just a little below with a lot of cloud and a chill east wind but with time of this persisting pattern comes a greater risk that cold Arctic origin or Continental air will come into play to the East and NE of Britain and without going into any detail at this range colder weather could infiltrate across the UK later at the same time as pressure falls from the West and wintry weather could become possible across the UK if this pattern persists long enough. So in summary despite the mild and springlike weather for a few currently March often ends up being a very contrasting Month across the UK with cold conditions very possible later to contrast to the pattern that we have now.

Some support for the more outlandish GEFS members from the extended eps. Tricky to see where the higher heights will end up on a more sustained basis after the Scandi ridge but some retrogression seems likely and a very wintry NH profile onset seems a reasonable option in a couple weeks time. (Greeny heights and Scandi trough broadly - if so, euro heights would dictate how cold we went. At this time of year, could be nothing notable)

Looking through the Op's of the GFS, ECM and GEM at day 10 ECM is by far the coldest with -7 and 8 850's widely

 

ECM1-240.GIF?07-12ECU0-240.GIF?07-12

 

GFS has more of a south easterly easterly flow so the 850's stay around -3 at the lowest

 

gfs-0-240.png?0gfs-1-240.png?0

 

GEM has the 850's slightly lower than GFS with the lowest around -4 in the far south

 

gem-0-240.png?00gem-1-240.png?00

 

The uncertainty remains on where the centre of the high will be further north like ECM would give a colder spell whilst GFS wouldn't be as cold

Day 10 EPS and GEFS clearly pointing to a strong +ve anomaly over Scandi/Baltic, though there will be uncertainty just where this high may centre, if its centred over the Baltic as per 00z GFS op then perhaps not as cold a feed as if it were centred further north as per 00z ECMWF deterministic.

 

EPS day 10

GEFS day 10

post-1052-0-73775500-1425720371_thumb.pn

 

The catalyst for this strong +ve HGT anomaly to build to our E and NE appears to be a lobe of the trop vortex shunting SE out of NE Canada/Labrador later next week which carves out a deep H500 trough over the NW Atlantic and height rises across the NE Altlantic/NW Europe and eventually NE Europe.

 

Quite a chilly easterly flow from 00z ECMWF deter, FWIW even showing some precip off the North Sea early week after next which at face value could be wintry. Of course high chance it won't come off as projected.

 

But, after thoughts of spring warmth today, too early to forget about winter weather for now perhaps?

There are signals late on in the GEFS for HLB 

They are toying with an Aleution ridge pushing into the Arctic and as the PV shifts Eastward.

Peturbation 9 when followed through is a thing of beauty....... even in March

Yes W79, GFS was nearly showing a split Vortex the other day and this continues to be shown of sorts into the extended outlook as Nick F points out, As always regarding these types of blocked patterns, I expect some interesting synoptic's to continue to show up in future runs before anything is resolved. Let's see what the 6z throws at us!

The GEFS mean at day 10 is superb if its early Spring warmth your after. And the southerly waft of warm air continues thereafter.

The ECM mean has more of an easterly component

Come back cold gang, winter is coming according to Ecm 0z...where is teits?

The ecm was hinting at this on 12z last evening and now it has upgraded it massively, could be snow showers pushing west in that bitter Easterly flow.

I am sure one of these days a D10 ECM op chart will verify when it predicts wintry synoptics, but fool me once...

 

The ECM op has no real support if you compare it to it's mean: post-14819-0-57928100-1425724001_thumb.g post-14819-0-74868100-1425724013_thumb.g

 

Bearing in mind the fluidity of the situation the op is not beyond possibilities but bearing in mind it's bias with projected easterly's, I would be wary until it moves into the more reliable seven day period. The GEM Control shows another possibility with the initial Scandi ridge pushing into Russia with another HP cell repeating the pattern:

 

post-14819-0-73878200-1425724351_thumb.p

 

The latest blog from Dr Cohen ties in with a UK positive pressure anomaly from week 2, with strong strat and trop coupling, so the main cold in the US and Eurasia, and therefore above average temps for our region: https://www.aer.com/science-research/climate-weather/arctic-oscillation.

 

The GFS 06z shows how fluid this pattern is with the core heights further south on this run, so a slack easterly quickly changes to a SE'ly:

No sign of retrogression to Greenland as early as D10 on this run (no surprise there) so at D10: post-14819-0-51245900-1425725070_thumb.p

 

Likely to change again by the 12z!

Morning all :)

 

Just looked at the output and read through this mornings posts. Definately some interesting charts on offer from the overnight runs and the 6z. Latest two GFS runs are playing with retrogression of a scandi high to greenland with a very cold plunge just to our east. I hope this trend continues and we can back the pattern west more to tap into that cold.

 

ECM 0z looks fun, with -8 850s coming in on an easterly. Would certainly feel like winter has returned!

 

Just out of interest, what do we need to look out for to make the easterly a snow shower one rather than a cloudy one? The 850s dont need to be as low from an easterly as they do from a PM flow for snow. We had snow showers here from a PM flow of -8 last Monday, so surely a -8 easterly flow is a cert??

Yes Chris the end of last night's ecm showed a colder continental feed spreading in to the southeast so you could say very good continuity to build on that idea from the ecm 0z. And not forgetting gibbys biggest cold ramp of the last 4 months in his summary this morning. For now it's fun but I always love cold eye candy.
