All eyes now on ECM. Law of averages suggests a fail, but let’s see.

ECM short but intense mini-heatwave. So ECM, UKMO and ICON (all European models) seem to be on that side, ending it in time for the weekend, while the North American ones are keener to extend the heat.

Not wanting to come over all Moomin but I’d say over the last few summers when we’ve had models showing an intense plumy ridge - including the record one last year - those that brought it to a close early rather than extending it tended to win more often than not.

ECM the most boring 12z of the evening but still hot. I'd imagine 30c Wednesday to Saturday for SE and EA.

It is a warm ECM run with a knife-edge situation on Friday with eastern parts holding on to the heat on Saturday - breaking down further west. Cooler for all by Sunday with the usual FI caveats noted.

High confidence for heat next week with intensity and longevity still to be determined. Two-day wonder? Lasting into July? Something in between? We'll see 😎 Not a bad situation to be in when the worst run of the big models tonight still has heat for many for a few days.

Agree that’s far too hot, but not sure that’s what Moomin was driving at.

Fascinating runs for next week.

I remember Brian saying last year how easily heat seems to build these days. When we get a plume 32C seems always nailed. I remember late 90s, 32C always felt like the highest it could go.

I know we're not quite at 'nailed on', but we do have cross-model support for mid to high twenties for much of inland England and Wales for Tues-Thurs next week with Friday included for the SE.


I think confidence is pretty high for a significant warm up next week if only for a few days. It could last into the weekend, too - however that particular option is "way too early to assume".

More than a months rainfall in places today, and all in all I'm pretty satisfied with what I called 10 days ago in terms of rainfall, although I accept, until today, it's been warmer than i had anticipated.

Sadly, as we move into astronomical summer, next week looks too hot for my liking, with night time lows perhaps pushing 20c by later in the week. 


But a summery mixed bag. Not a write off, and the heat lovers will no doubt relish it.

Some cracking runs tonight - here’s hoping we can breach the 30C barrier soon. The Azores ridge is now creeping into the reliable timeframe (t+96), so we’re nearly there. The extent and duration of the heat remains to be seen.

However, next week is a long way off, and while I accept it looks like a brief hot spell could be coming, it looks like a blink and miss it affair with much more mobility soon after.

 Mini Heatwave next week or extended spell of heat? At the moment i would pick the former., I will know better by next Friday.

Nice output for Summer fans this morning, GEM is still very hot. GFS not quite as hot but prolongs the settled spell all the way through to day 16 for the second run in a row.

For the following week it breaks up and does very little.


GFS - LP spins up on the Atlantic 985mb Sun 21st and then stands back enough to draw up air from tropics by Wed 24th (though NW Scotland may not see this) A short break as a more westerly flow pushes in on Mon 29th, then the pattern of Atlantic low drawing up warm ir from the S/SW repeats on Wed 1st and Sun 5th with slack circulation between. The Sun 5th chart (a long way off!) hints at some thundery stuff from Europe mixing in.


GEFS - very warm and dry for the S Tue 23rd - Mon 29th after which a lot of scatter but probably cooler though still above average, and small amounts of rain. Te further N you go, the sooner the rainy period starts (in Scotland never really dry) and the warm period less marked. though still pleasant enough.


ECM - has intial warmth as GFS and then a weak trough over the UK Thu 25th before bringing in a more W-ly though still warm flow,
