Summer continues unabated here in the southeast. Despite the 'cooler' feel now temperatures can still be expected to reach 26c (79f) today and 28c (82f) tomorrow. The heat this year since March has been effortless down here.


Nothing too troubling for the foreseeable. 


Continued short notice waves of heat can be expected in the largely slack regime. 


No chart available for the selected hour. Many charts start at 3 hours ahead, so if you have 0 hours selected try stepping forward or selecting a later hour.

The last few GFS runs have consistently shown a big realignment of the pattern from around the 20th July. Can't tell with the others as they do t go that far yet. It's certainly there in virtually all GEFS members: building of pressure to our North East and a more SW-NE alignment of the jet replacing the current NW-SE flow. A dropping of pressure in the West of the Azores high region too. At the moment it's showing warm dry weather but any big pattern change always risks being for the worst too.

Will be interesting to see if this comes to fruition. To get this kind of consistency there must be some big modelled change upstream, over the Pacific. Switch in the MJO or PNA patterns I assume.

Ecm builds in the Azores high very nicely end of next week . High 20s again in the South.

Some respite from the heat and dry conditions down here this week. A good soaking now probable for the SE.

But my garden could do with any rain that's going, so not a nuisance there.

More than just another plume- if an easterly sets up from this, 2003 comes to mind.


But it is the GEM.

Definitely a warming trend being picked up now by the gfs ensembles.  Some very hot runs in there by the end.

Quite so David. It will be interesting to see how this pans out. I'm far from convinced that the amount of rainfall being progged will be received. Convection by its very nature is hit and miss and normally steers clear of the south coast if there is any maritime influence from the channel in there. Tuesday nights rain event could still slip further south leaving us high and dry.


We shall see.

Just looked at Accuweather and i see no signs of anything that hot up to the end of July. Been pretty accurate for this area last couple of months , certainly better than Met Office automated forecasts.

ECM 12z op run is about as good a run as I've seen from any model at any point in the last 6 weeks or so. It would pretty much guarantee the entire UK a decent spell of summery weather should it verify as shown.

Stunning ecm especially for those in the south but all areas get in on the act by day 8. And by day 10 looks to be setting up a prolonged heatwave.

If ECM12z verified I'd not be surprised to see 100F in the UK late this month.

That said, 37C was recorded at the start of July 2015 somewhere in the south and that didn't turn out to be a prolonged hot spell. My recollection is that the hot spell broke a few days into July and then it never really recovered for the rest of that month.

I can remember that every summer month in 2015 had a cooler than average CET and of course, that is still the last cooler than average summer to date, which we (by that, I mean the area which is covered by CET records, and not specifically in the part of the world where I am) have had according to the CET records.

I see we're starting to sniff out the potential on here - well I say that, Brian spotted the potential way back at the start at June in the TWO summer outlook. If a fine warm/hot later-July (and good part of August for top marks) does indeed come around I will be very impressed 😃

We haven't really had that many, if any, especially good Augusts since that incredible first fortnight of August '03.


FWIW, I recall that the summer of 1990 had a poor June in my area and the weather remained so until around mid-July. But the middle weekend of that July saw a real transformation and that summer ended up giving us what was the hottest day on record in this country at the time at the start of August. (37.1C at Cheltenham on 3/8/1990 I think it was).

850s around 16/17 July are now getting close to 12C. Nothing exceptional but possibly another fine snap crawling out of the woodwork. Seems to be happening a lot this summer. Would make for an interesting winter set-up -10C 850 incursion popped up frequently in Dec/Jan/Feb.

Nothing past the next week is certain as per usual although the heat to our South does remain there and if tapped into (A big IF) there are some possibilities of another hot spell at months end as you said.
