Model output discussion - Post SSW - Will it turn cold?
mulzy replied to Paul's topic in Forecast Model Discussion
ECM rock solid out to day 6. -10 850s widely over the UK by then! -

Block as depicted by the eps mean just about holding on from days 6-9. Lower heights to the west encroaching - there will be some milder runs at this stage. Clusters will reveal more later. -

Early doors on the eps - pretty good support for the operational. In fact many runs will be colder. London 850s at day 6: Mean =-5.5C, Control=-8C. -

Hang on, ECM actually not too bad at day 4... Compare with GFS -
Indeed it is. I am now looking at the long range CFS December 2018 charts (does it go out that far?). Maybe, just maybe we might have a little lying snow then!

UKMO is poor compared to its 0z run BUT it's still better than the GFS. However, a very disappointing start to the evening runs in my opinion -

For a faster evolution to cold, try the GEM! -

The interesting bit is east of the UK (what we can't see). I think this is not bad chart at all with the trigger low possibly in play just to the east. -

Chillax folks - the EPS is looking very good out to days 7/8/9 (better than this morning's set). -
Model output discussion - proper cold spell inbound?

If we have snow on the ground, that will knock a degree or so off these temperatures. Whatever, we are still looking at quite a notable wintry period. -

Even then the GFS will probably flip to mild! -

JFF, but the eps control run is crazy from days 12 to 15 (-12/-13C 850s widely across the UK). -

ECM is still flat-ish. Dear oh dear, the drama! -

Sure - day 15 not too shabby though! -

GEFS much more amplified at T+162 (12z vs 6z). -

Indeed Nick. We can not dismiss the ECM like some members are doing - that’s pure denial. We probably need to wait for the rest of the ECM suite but a number of ECM / EPS runs are saying no to a quick tropospheric response. -

Disappointing medium range charts this morning. ECM Det continues with it's flatter evolution which has support from its ensemble suite. It's fair to say this could be a slow burner... EPS Day 10 mean GEFS Day 10 Mean GEPS Day 10 Mean -

Days 11-13 shows the lower heights to the west having more of an influence but we do get a decent set up with very strong heights directly to our north by day 15. -

Disappointing ECM suite this morning. The eps mean at day 7 doesn't show much Atlantic ridging while the day 10 mean still shows the Canadian segment of the vortex still having an influence. Maybe the Atlantic height rise horse has bolted in the day 7-9 range? Tonight will reveal more... -

I don't think it will be 'super cold' but hopefully trending in the right direction. Control looks decent. -

Extended eps stays on track; higher than normal heights to the north, lower than normal heights to the south. Slight change of emphasis in that towards the later end (days 14-15), the focus of the higher heights is moving west towards eastern Greenland. -

Very zonal 12z ECM, though the PV does relent at the end of the run. Where it would go from there, no-one can say but no eye candy within the 10 day range for sure. -

The fact that people are planning to stay up all night shows how desperate times are. 2.1C here now.
