GFS 18z yet another progressive outlier. What is it with the op run recently?

Perhaps not quite the excitement in here that there was a couple of days ago but it looks like a notably hot / very hot and humid spell is creeping out of the woodwork. Peak heat still favoured next Friday and GFS is consistently pushing temps above 30C. I expect we'll start to hear more speculation very shortly about the potential for mid 30Cs. 

PS: Someone asked about me about the potential for rain in the Chilterns yesterday. In the end we literally had a few drops and they were nowhere near enough to register on my new VP2.

Amazing how far north the hot air gets. 15C isotherm to the north of North Cape, that’s about 72 degrees north!

Weather for the Wee Ahead suggesting widespread plume thunderstorms on Sunday week (29th), but GfS and ECM charts this morning, while not excluding storms, are less definite.

That is one helluva hot ECM this morning. And no breakdown either. It goes on and on. I think our splash of rain yesterday may be the last for a while.

Or tomorrow if we can get 32C as well.  Friday is now only 6 days away and they been consistant on that day so hopefully it stay put since now is the peak of the summer, and tomorrow the last day for sunset at 9pm which is sad to see it going down but the heat avallibity can stay longer.  Like what Moomin said ECM had been showing hot runs for a long while now and must be the best performing model.  No rain here lsat night as i checked the car roof to see if there spots since I last washed it 3 weeks ago.

I think the heat will peak on Friday/Saturday. I think the models are flipping between both days 33-36 seems a good bet right now

I’d hazard a guess that Saturday will be another very hot day and a shift in air stream will take place briefly Saturday night into Sunday before high pressure returns with little or no rain in some parts. This has been the story of the summer so far; it’s not out of the realms of possibility that the low pushing in from the West actually corrects further north.

Next weeks temperatures are really a sight to behold.

Is this "Death of the Westerlies" linked to the slowing down of the Gulf Stream which I have been reading about recently? Or are the Earth's magnetic poles switching? As Sherlock Holmes might say "Something is definitely afoot."

GFS 06Z much warmer out to next Thursday. Hot air is being sucked up from the south as the low stays a little bit further west.

BBC forecast just now mentioned temps getting into the mid-30s by the middle of the week.

Everything is shaping up for a hot week!
