The outlook is more mixed, however I'd not be surprised to see very warm or hot weather returning at short notice.

GFS shows repeated plumes heading north over E Poland to Scandinavia, backed by forecast temps here http://www.wxmaps.org/pix/temp4 . Just a bit further west than forecast and we could have another hot spell.

Boy it’s quiet in here. Is the output that boring?

This morning's GFS and ECM output have LP in the area of the UK for the next week or so - looks localised and showery rather than major depressions pushing fronts across the country. Fax chart and MetO forecasts have brought in a more well-defined showery low over England for Sunday/Monday - the way this has become more prominent over the last few days' forecasts suggests to me it will continue to develop.


But the end of the ECM and GFS runs look sunny and hot leading up to the next bank holiday. Two warm and sunny BHs in a row? Surely not!

The models seemed to have flipped back for changeable weather through to next weekend with the Royal Wedding in a week's time Is there any consensus on whether the current mixed and changeable conditions will continue pretty well for the foreseeable future to include next weekend or are we moving towards a dryer and warmer spell ?

Having said that, the 19th looks like the wettest day of the lot on the ensemble!

A lot of next week looks fairly settled according to 12z UKMO

Quite a turn around in the past few days just as it looked like high pressure would build north of the UK it now looks like it will be lower pressure instead meaning a settled spell for the UK

GFS and ECM have the Azores High or a cell split off from it close to the UK for pretty well all their runs, so mostly dry and settled. But the HP is rather variable, sometimes broad, sometimes narrow, sometimes up towards Scotland, sometimes down over the Channel.


So I don't exclude frontal rain brusing past the NW nor a spell of cold NE winds affecting the SE, both of which can make those affected  wonder what happened to the HP. Need to watch developments day by day.

Yes the outlook is becoming increasingly settled it seems with HP much more dominant than it was looking a few days ago. Even this weekend looks milder and drier than it did.

The coming week or so looks like pretty standard late spring / early summer fare with. NW/SE split less settled cooler Northwest under Atlantic influence. More generally settled and drier southeast with more influence from the Azores high nudging into continental Europe.

100mm+ of rain in 48 hours over a large swathe of central France. Stalling cold front. Up to 100mm in a week in a lot of Central Europe. For once the U.K. is looking a lot better than the continent.

Something of an upgrade to this week's weather, with the main models showing more extensive HP and a warm source of air (though extreme NW and SE cooler at times with onshore breezes).But the longer range from GFS has gone downhill with a depression off SW Britain now predicted for the bank holiday weekend. Well, that's MRFs and bank holidays for you

Sames goes for the royal wedding next weekend. At one point the runs were showing a deppresion in the channel, making for a thoroughly wet and miserable day in southern England. I know it's still 6 days away and not 'nailed on' but it looks like being warm and sunny for that day. A sudden reapearance of that channel low would be most unlikely at this stage.
