Model Output Discussions 12z 03/05/2016
SMU replied to phil nw.'s topic in Forecast Model Discussion
I cant see any ECM clustering around 30c & as it stands that means 35c is unlikely The mean is nearer 25c - so reality if the clustering is 25-27 - the maxes are expected to peak 31-32c Thats a notch down on yesterdays expectations - as the mornings runs are yet more progressive than yesterday.... -

Some people getting carried away talking about records & 2003 - theres a reason its a record because the conditions were totally optimal - The current outlook doesnt look as good - infact the evening trend hasnt been that great - moving the hot uppers eastwards quicker - certainly a hot plume on the cards however its still a few days away yet so the pendulum could swing either way ! Also looks to windy for record breaking heat - ideal conditions are dead calm still stagnent air - I will go with a punt of 34c being the top temp -

ECM somewhat more progressive than the GFS & more indicitive of the usual Uk hot spell.... still his 21c uppers though- -

Afternoon All- Todays runs are touting the kind of flow that is like the holy grail for heat as is the mythical easterly in Winter To get upper air temps of above +20c over the UK ( rather like -15c in winter ) does take a rather unique set of circumstances - most importantly that direct southerly flow with substantial High pressure to the east, the High needs to remain in Situ long enough fo that +20c isotherm to be pumped Northwards - More recent summers havent seen high Pressure remain stable & in situ long enough for this to happen - mainly as the atlantic has ushered in more unsettled weather before the plume gets going- consequently the hottest air generally curves NE into France- Its looking good this time though- I suspect the Ensemble peak will be up around 17-18c this afternoon - it will be another 48 -72 hours before the detail around the illusive 20c line can be persued with a little more confidence- To chase North of 36c we would need more than 2 - 3 stable days- .... You never know s -

If we look at the current runs they are very similar to the hot spell the other week with a surge NE of the azores High - up until around 120-132 the models wanted to flatten the pattern quickly & carve the trough out to the North - Thats whats being modelled again - however the ECM is prolonging the heat - if last time is anything to go by ECM could be closer to the mark... - lets hope so! s -

Arctic Sea Ice Discussion 2016: Melt Season
SMU replied to BornFromTheVoid's topic in Climate Change
I think this years melt & expected record smallest coverage is almost to be expected - At this stage my thoughts are not that we may break the lowest record but by how much - Since winter Ive had the World Meto office FB page liked on my phone & nearly every update was commentary about heat records being broken over the arctic - circa 6c & above. all relating to the global 1c ( or 2c?) threshold being broken- also record warmth & iceloss over greenland has featured on there. Come Septemeber I think we will be looking at a picture of ice cover never seen before in its sparcity.... S -
Yes a very convective flow- The -9c line now progged into the midlands I wonder if we could hit the magical -10 line - that would be truly remarkable added to the mix is the prospect of the April CET coming in around 7c leaving the May CET target if about 8.5c for a even more remarkable spring colder than winter statistic!

Not often you see a -16 degree anomaly over the UK ECM has the -8c isotherm into london at 192 - for the last week of april thats ultra rare !

The ECM 12z at 72 looks very wintry across the central belt of the UK Usual elevated areas could see a covering Saturday morning ....
