I reckon that going by the current output, this month will do well to finish even close to average, let alone above.

My hunch now is a definite miserable wet summer - certainly the rest of June will be miserable and wet.

Sometimes things seem easy to forecast!

The cold start to this summer shows that quite clearly because although the negative temperature anomaly is quite big at the moment, I haven't heard of any records being broken for that or even being challenged whereas it would no doubt have been a completely different story if this summer had started off on an exceptionally hot note.

There clearly has to be some scientific explanation for that and if that isn't climate change, what is it?

Plenty of sunshine and average temperatures sums up the outlook for the next week, at least down here. No heatwave (thank goodness), but not cold either. The mean high here for mid-June (91-20) is 20.5C, compared to 19.1 in the 61-90 period...

The new and improved MetO raw has 21 today, then 19, 20, 21, 20, 20, 20 for the next six. GFS, for comparison, has 17, 15, 17, 18, 19, 15, 13... but it's barely worth taking note of, it's been atrocious this year and continues to be so.

WX temp charts back in pessimistic mood today. After yesterday's suggestion of warmth moving well northwards, today a weak advance of something a little warmer into NW Europe in week 1 is followed by a renewed retreat as cooler isotherms (14C and below) move into E Britain, Germany and Scandinavia (the last of these was shown yesterday as really warm). Outlook for dry weather has improved though. Nowhere is absolutely dry but today WX is showing France as wet in week 1 (yesterday it was Britain) and the Baltic/Finland in week 2.

GFS Op - current LP hangs around and dominates Britain until Tue 19th when it moves off N-wards. A weak ridge of HP follows from the W but SE England more affected by LP 1005mb Belgium Thu 20th et seq. New Atlantic LP approaches Scotland Sun 23rd with a spell of  cool zonal W-lies from Sun 23rd, later NW-lies. As this moves on to Sweden, a N-S ridge of HP sets up for Britain from Thu 27th, with N-lies for the E Coast and SE-lies for the W coast.

ECM - sticks with its predictions of yesterday; like GFS until Thu 20th when it places the HP further S so the SE is not affected by continental LP and Scotland has fresh W-lies.

GEM - slower to clear the current LP out of the way and then straight into the zonal pattern with HP scarcely putting in an appearance.

GEFS - temps getting back to norm in the next few days (in Scotland already so), and the mean stays there as the various ens members diverge - just a hint of something a but warmer after Thu 27th (jam tomorrow!). Quite a few ens members have a cool and wet period around Thu 20th in the S, drier later, but otherwise some rain at many times in most places, wettest in the NW.

Better 0z but a real mixed bag. The jet looks to be firing up and it's whether it goes north or slams into the UK. Toss a coin atm.

Looks like a heat dome setting up over the eastern USA this is probably what's firing up the Jet? 25c 850s on the east coast dont think I've ever seen that before.

That said, summer 2015 did I think record a below average CET for the season as a whole. This was a surprise to me as it didn't seem like an especially cool summer at the time, especially when one considers that it produced the UK's then hottest July day on record on 1st July.

Even on those odd occasions when we get a really cold spell in winter, that is still usually unlikely to break any actual records whereas high temperature records are broken on a regular basis with that tending to be the case regardless of the time of year when that's happening.

That is the point which I was trying to make here and so it is the all year round pattern of these records which I was referring to rather than just the scenario in summer.

We have to look south for our heat.

I think Helen Willetts of the BBC said the other day that it was the almost complete absence of any frost in all/most of the UK (largely a result of the dominance of cloudy & wet conditions) during the spring that was as much of a factor in the overall warmth of the season as the very warm daytime temperatures seen at times in May. Perhaps March and April were warmer in other areas, but to the best of my recollection neither month was never especially warm here at any point.

The issue is, as I said in my earlier post, CET bears no resemblance to the daytime weather perceived and experienced in Spring. Because of the high amount of cloud we have had this has a far greater effect on raising the overall temperature than lack of sun depresses it. So people notice the awful wet cloudy daytime weather with the slightly below average maxima making it one of the worst Spring's I can remember here (in the overall concept of "summery weather")
