WX charts; yesterday's northward advancing warmth put into reverse. Milder weather hangs on in parts of Europe (esp France and Hungary in week 1) but is pushed back SW-wards by rather cooler air from NW Russia affecting as far W as E France. Little change for Britain, on the edge of this - just about mild for week 1, cooler for Scotland in week 2. Small amounts of rain for most of Europe in week 1, then a dramatically large and dry area over Scandinavia and the N Sea in week 2 with rain all around its edge including Ireland and (mostly) W parts of UK.

GFS Op - pressure rising over Britain from tomorrow and well established 1025 mb Thu 9th, weakening but then re-establishing over a large area of the Norwegian Sea 1030mb through to Wed 22nd. For most of this time, the HP area is large enough to determine British weather, though Atlantic troughs keep approaching Ireland and falling back; but one of these is strong enough to run SE across Cornwall 990mb Tue 14th.

ECM - agrees with GFS to Mon 13th but the trough on the following day is a much broader affair and further east, overing the whole N Sea 1005mb by Thu 16th. Any HP is further N, near Svalbard, and by no means intense (1015mb)

GEFS - temps rising to warm by Mon13th, with good ens agreement, dropping back to norm (more slowly in N & E), ens members quite well bunched but with several warm outliers. Rain at first esp in S, then dry to the 13th (some in the NE on the 10th), after which rain present in many runs, more extensive than yesterday, heaviest in W.

Could you elaborate what you mean by a back loaded winter? Are you implying the weather  for the week ahead is showing winter type weather?

WX temps warm/mild for Britain and France in week 1 but there's a large area of well-below average temps in W Russia and this is exported to cool down all of Europe away from the Med in week 2, even if the actual freezing area decreases. Dry around the Baltic in both weeks, this extending to S Britain in week 1, but otherwise patchy rain well distributed across Europe barring S Spain.

GFS Op - HP building in from the SW reaching max extent for Britain 1025mb Thu 9th. It then retreats E-wards to become centred S Baltic, but still mostly the dominant influence for E Britain while troughs approach Ireland from the west (typically 995mb, predicted for Malin Mon 13th, Fastnet Wed 15th, Brittany Fri 17th). By Sat 18th the LP has spread to cover all of Britain as a slack feature; then HP as a brief ridge before LP south of Iceland projects a trough down the W coast Wed 22nd. For all this period HP is oscillating between N Norway and C Europe.

ECM - repeats the development of the HP to Sun 12th, then the LP near Iceland extends a trough SE-wards across central Britain, not the W, and as a persistent feature, distant and shallow at first but becoming centred 1005mb Wales Thu 16th. The HP over Scandinavia is centred further off to the NE than in GFS.

GEFS - Quite good agreement on temps throughout; increasingly warm to Mon 13th after which dropping back to norm with a few mostly warmer outliers. Dry until Mon 13th, then rain on and off, driest in the NE, chance of a heavy burst esp in the S to start with.

I see that Edinburgh is currently being modelled to finally get its first temperatures of this year of 20°C or above by this coming weekend, so that will be something to look forward to if that comes off, especially if that comes with some badly needed and very welcome sunshine.

WX temp charts show an improvement on yesterday, the mild/warm weather still in place for France and Spain in week 1, almost touching S England, but then in week 2 spreading across NW Europe to Poland, including England (Scotland also milder). Yesterday's prediction of a cooler period in week 2 now heading south along the line of the Urals. Very dry over Poland and S Baltic week 1 (also S Spain), this area moving to N Sea and N Baltic week 2. Some rain in much of NW Europe week 1, but heavy over France and the Alps week 2 also affecting S Britain at that time.

GFS Op - current HP moves to Norway Mon 13th as LP comes in from NW to SW Ireland 995 mb. This LP stays in position, filling slowly, to Thu 16th sandwiched between HP Norway and HP Azores before the areas of HP link up and the LP moves SE-wards to the Alps Tue 21st but leaving a lingering trough over England. By Fri 24th the continental end of the joint HP has moved S tp Poland and Britain is under a combined ridge.

ECM - differs from GFS after Mon 13th with HP developing not over Norway but to SE of Iceland. The Irish LP is still evident but by Sat 18th that has begun to link to LP 990mb Novaya Zemlya threatening NE-lies, and no block over Norway to prevent this.

GEFS - becoming warm by Mon 13th ca 4C above norm, then a sharp drop, but recovering to norm or a little above for the next 10 days, quite good ens agreement. Rain for most in the few days after 13th, thereafter becoming regular and persistent in the SW but occasional and in only some ens members in the NE

WX temps; forward and back. Yesterday's suggestions of warmer weather now only applying to France and Germany in week 1, though the rest of Europe incl Britain is fairly mild (as this is a weekly average, the warm weather forecast for Britain for the next few days is presumably offset by a cool down to follow). The cool influx from the north previously shown over the Urals has now transferred to the E Baltic for week 2, though not much change for Britain; any really warm weather stays along the Mediterranean fringes. Rain in week 1for France up to Norway, less heavy in Britain, very dry in Spain; in week 2 the heavier rain moves to C & E Europe with countries bordering the N Sea just a bit damp.

GFS Op - current HP moving off to Scandinavia by Mon 13th, replaced by LP from NW arriving W Ireland 990mb by that time. This moves to Scotland first deepening then filling to become a shallow trough lying N-S over Britain by Thu 16th between HPs Atlantic and Norway. The latter HP collapses and HP moves in to Britain from the SW 1020mb by Tue 21st intensifying and covering the whole country by the 23rd.

ECM - very much like GFS

GEFS - temps mild or warm to Mon 13th, then sharply dropping to norm, staying there with good ens agreement to Mon 20th, after which mean still near norm but little consensus. Dry to 13th, (11th in NW) then rain in small amounts on most days, tending to be more sporadic but occasionally heavier in NE.

Even with that though, Edinburgh came very close to getting its first 20+°C temperature of the year yesterday with a maximum temperature of 19.8°C being recorded at the botanic gardens, making that station the warmest location in the south of Scotland during yesterday (hence its presence on that list).

According to the Met Office, today's temperature is forecast to reach 19°C here in Edinburgh but we could sneak up to around 20°C or higher if it ends up being a bit warmer than expected, especially if we actually manage to get any sunshine (something which we hardly ever see these days).

Tomorrow's high is forecast to be around 21°C here in Edinburgh with Saturday's forecast maximum now been upgraded to around 23°C.

However, the BBC/Meteogroup don't have our temperatures getting as high as that. According to that forecast, the temperature on Friday and Saturday is not forecast to be any higher than around 20°C and if that is right, we might well have to wait a bit longer still for that elusive first 20+°C temperature of the year here in Edinburgh.

This shows that for here in Edinburgh at least, there is currently quite a bit of uncertainty amongst the various models, regarding just how warm the next few days are going to get in this part of the world.

It still amazes me sometimes how easily it can get warm out the blue, 23c today and tomorrow then 24c Saturday & 26c Sunday, if only the reverse were ture. Seems nearly impossible to get a below average month now. Would take an impressive set up even to end up average 🤔

Whereas up here, the forecast has changed over the past few days from glorious and sunny with temps up to 23c on a beautiful easterly flow from a big high centred over Norway, to positioning the high further SE to centre over Poland/southern Baltic, bringing a more southerly flow and allowing fronts to encroach from the west leading to showers here and temps maxing at 19c/20c.

🤮

I keep getting my hopes up for a high to establish itself over northern Scotland/Shetland/Faroe like in early summer 2018.

21st - 24th May 1922 when 30C was reached every day somewhere in Britain

A date record of 28C or fractionally under has been recorded for every day in May, but usually in bursts of only 2 or 3 days. Date records for Sat 11th and Sun 12th are 28.3 and 30.6C, both from 1945.

3 fine days with temps topping 24 or 25c where the cloud breaks. Certainly nothing remarkable for May and the only remarkable point is just how wet and dull spring has been on the whole. Masked by a slightly warmer than average CET. 
Still waiting for 20 degrees on the south coast on the 9th May is quite a marked change from recent years. 
Thankfully after next weeks monsoon signs look promising for decent high pressure but of course this is a long way out and subject to change back to the Siberian spring with fingers lurking near the thermostat button once again.

I think that should put paid to any talk about it having been a cold spring, or indeed a cold year. There have been only two short spells of cold weather in the 129 days we've had so far this year: around 12 days in January, and a week in April. The rest of the time has been generally above, if not well above average. And, of course, we're back in the 10% club - as in yesterday was one of the top 10% of CET maxima recorded.

May so far has been more like what you'd expect in early June.

3 more days of this to go, then it looks like getting back towards average. I still maintain that in the past 20 years a certain chunk of the population seems to have thought Britain is now a Med country!

A steady mean skewed by above average nights does not excuse the lack of decent daytime temperatures since the start of spring. It’s been excessively dull and dreary with gales often making it feel much cooler, particularly in the south. 
Hopefully June will herald some proper barbecue evenings but we really shouldn’t be waiting still and saying this in mid May.
