Despite some of the doom and gloom predictions about this week it's actually not looking bad for most of this week, there will be plenty of sunshine, a few heavy showers dotted around today but the risk of showers then decreases for a few days and with light winds and the very strong late May sunshine the temperatures will really respond, into the high teens to low 20's celsius, taking London as an example, somewhere around 20 / 21c this week give or take a degree or two..nae bad!

The ecm has the waving front bringing rain to N. Ireland and western Scotland by midday Saturday This tracks east, mainly north of a line north Wales > Wash, and clears into the north Sea by midday Sunday. The cold front following on will clear the south east by same time leaving a residue of showers. By midday Monday another front is bringing rain to western regions,

It's an ok-ish week. Temperatures around 18-20c are actually only average for this time of the year in the SE, so nothing too amazing, but better than of late I guess. Weather remaining very slow moving for the time being.

Perhaps hints of a foundation to something better into June, with a real collapse in polar heights from today to day 10 on this mornings ECM:

If I'm really honest, I can't see precisely where this morning's 00Z is headed; other than that there's no sign of either protracted heat or persistent cold::cc_confused:

The FV3 (wonderful model) has this towards its end, however::yahoo:

But, despite the over-all rise in SLP, the ensembles don't engender much in the way of unparalleled excitement, either:

The Ecm 00z ensemble mean is nae bad, plenty of ridging this week means plenty of fine and warm weather after today's showers, a bit more unsettled later but the azores high looks poised at T+240!

I have to say I find this chart from the GFS at T210 bizarre, in that not likely to happen, 

image.thumb.jpg.7fdea9dff554767dd97c947113f0ea2f.jpg

Is that low really likely to sit there for that long?  If the Atlantic really is that weak then when the ridge does finally make it here, it might be here for some time?

no?

this doesnt look very inspiring if it was to become reality

Looking at UKMO we have some heavy showers developing today and tomorrow mainly in Scotland and down the eastern side of England

Mid week sees a lull with plenty of sunshine on Wednesday with temps around 15c to 20c the one exception to the sunshine looks to be northern Scotland where rain remains likely

Thursday and Friday look mostly dry with temps again 15c to 20c the odd isolated shower can't be ruled 

Saturday and more especially Sunday could see a greater chance of widespread showers as low pressure moves in

The ECM 00Zop also has chilly polar maritime air spilling across the uk until the 24th May and again after the 28th.  Some of us aren't in the South.

Temps for Cheshire this week are showing mid teens and cloudy while London is getting the low 20s all week so nothing really to get excited about if your a northerner looking for sun and warmth.

Decent outlook for the South now. Less so further north, but that is situation normal.

Average conditions, which in May is pleasant in the South East.

A much better-looking end to the FV3. Stonking model! All we need now, is quasi-stationary, north-south-orientated Atlantic trough to form?

06Z ensembles still suggesting an over-all warm-up late on -- just around the time the SLP charts go haywire:

But, as the UKMet point-out, in their long-range forecast: there are no strong signals, going forward?:oldgood:

Yes indeed Pete, no strong signals, but talk of the Atlantic remaining quite subdued, which would implie, perhaps longer settled spells when they get a foothold! Could we be looking at a more balanced summer this year.. More typical as regards to high pressure bringing plenty of settled Conditions to the south, but more mixed further North!! I can understand those up North being a little peeved with current conditions.... Just stick with it, you will get some decent weather before long..

Bank Holiday Sun is always welcome - but it's so bone dry here even in West Lancashire - the River Ribble can be easily waded across in some areas (not that I recommend it!)

Vile?? How dare you resort to using doom merchant swear words. I'm sure you can sniff out some glimmer of hope in the cfs 0z to cheer us up.
