I actually never forecast the coolest wettest June, I merely said what the models were consistently showing that it was likely to turn cooler and more changeable.

It didn't, which shows the infallible nature of computer models.

I think July is likely to be cooler than June, but not cold...

Time, as ever, will tell.

See the heatwave thread - Brogdale was right in the prime spot for the heat on Monday. It took its time posting the reading though!

Kent was strange on Tuesday. The Downs never got the really hot stuff. My vineyard, which is only about 15 miles from Brogdale, got to 31.5 and then stuck there all afternoon. Actually peaked lower than Monday. Whereas in July 2022 I got up to 39.1C.

Pub run special for next weekend.  There was a time when sight 20c isotherm caused a meltdown on this place. Now its almost routine

Time was, 28c was a very hot day 😉    Now it's just "standard" ......  ?   

Not sure we'll seen any below average days here in S Worcs at all this month.  Certainly nothing on the horizon atm.    That in itself will make July a very warm month, probably one of the warmest on record.     As well as continuing one of the driest periods on record.   

Personally, 18c and rain every day would make a very pleasant change 😛

Borderline very warm perhaps.

Well the GFS0z is very hot three 100f days in a row.

From next Saturday.

The actual ECM 12z is all a bit uninspiring again too though.

I really do think we've seen the hottest spell this summer.

I also think we will get continued dry and summery weather at times, but more standard stuff, 27-28c, which will do just fine!

GFS 00Z run is another 76 Special with 11 consecutive 30C days, of which four are 36C+. Surely a record-breaking 20C+ CET month if it came off.

Unlike usual, the hot stuff isn't being pushed back either - it arrives by the middle of next week.

28C was always the gateway level to “hot”. Even now in a warmer climate there’s something quite magical about 28. It’s when being outdoors in trousers becomes a little uncomfortable and the heat hits you when walking out of air conditioned buildings. It can still feel a tad chilly in 27C in a breeze.

Anyway, GFS has another heatwave setting in next week with 37c+ for several days.    So all rather moot!

Note how MF calls 25 to 27 "hot" in the SE, which it was - using the official MetO definitions. The BBC, at least in the 80s and 90s used their definitions... they were meticulous about it!

An increasingly hot outlook later next week. Consecutive very hot GFS operationals as well, and it certainly isn't without support. Even the flatter ECM this morning becomes at least very warm, it just stands out more for not being extreme!

Predictions that we've already seen the peak of the heat this summer and July being cooler and less settled... hmm!

Not that it matters hugely in the context of the original post that argued 28 was “very warm, maybe”.

I assume there is some tropical forcing for this, like an active MJO. In any case perhaps this is what’s causing the Met Office monthly  outlook to talk of more widespread settled weather in late July.

Put simply the GFS Op run is one of the most extreme runs I have ever seen for the southern half of the UK, and it isn't a wild outlier

...and to be clear, I certainly hope I am wrong.

He would certainly get less hositility of claims were back up with clear model evidence.

Someone a few days ago predicted a total wash out for yesterday (Thursday 17th),it actually turned out to be the absolute opposite in fact was a beautiful day here, temps of 24 sunny intervals and a nice breeze, perfecto I’d say.

The July washout and no more hot weather for July is possibly a bit of reverse psychology ? Seem to recall this happens in winter too from certain members. Try and find the opposite of the general theme, eventually they will be right

I posted a few days ago as the weather started to turn more changeable with average to above average temps that I wouldn’t  bet against temperatures rising above 30 within 2 weeks. I’d say it’s almost nailed on now,it’s almost rinse repeat rinse repeat this year.

I will say, it has kept the forum busy so far this summer, normally this thread last the whole summer, I predict it a new thread will start again before July is out. That’s my summer prediction 😉
