So when do we officially consider this hot spell to begin?

My benchmark has generally been somewhere breaching 28C. We’re nowhere near so far this week - nothing above 24C. Could happen on Friday, or at a push and with a following wind (and less cloud than forecast) Thursday.

Quite an unusual heatwave where we don’t know if in only 4 or 5 days it will be 30C or mid 20s, but we kind of know it’s likely to be in the 30s in over a week’s time.

30c knocking on the door for many places by then.

It remains on, despite this morning’s GFS op.

And this morning’s GFS op doesn’t stint on the European heat either, it just displaces it. Southern Iberia gets to 45+ this weekend and then sticks with it every day until 384 hours, peaking at 50C. Unprecedented.

All other op runs showing heatwave conditions for the UK. Only question is whether we threaten records.

At the moment it is looking likley the uk will get 2 or 3 days at most of extreme heat,very similar to what happened mid June. It certainly does not look as if it is going to last,thank god! As with the models in winter overcooking the cold iam awaiting the inevitable downgrades wef this weekend. My bet is somewhere will hit 35c-36c on one day but to get 40c in this country we need a prolonged spell of heat beforehand.It might happen but very unlikley imo.

Ideal for me would be at least a week of 28-32C and then one extremely hot day, or 2 at a push.

Some interesting facts about the highest recorded temps in each of the European states:


Highest temperatures in Europe: A map and list of records • viborc.com


A good chunk of them have recorded 40c or more in the past, even in the 'near continent' regions, but Greece contunes to hold onto the the top spot with its 48c that was recorded in Athens

While we wait, worth monitoring where’s hot in Europe right now.

Current continental hotspot, with a mere 40C, is Kryvyi Ri airport in Ukraine, near Dnipro.

Next few days it’s going to be Spain.

Another 39C in this evening's GFS, though GEM looks like it would peak lower. Meanwhile the 40s start in Southern Iberia. 41C tomorrow, then it's up from there: 44, 46, 45, 45, 45, 48, 48, 45, 42

The Beeb are finally getting off the fence. Schafernaker just said it’ll probably be above 30 in the South all next week.

A good chance of the all time Spanish record going I'd think. For reference it's 47.4c recorded just last August.

Currently living at roughly 65m asl North of Cowbridge in the Vale of Glamorgan.

Some consolidation now for a few days of extreme heat later next week as we tap into the heat dome across Spain and France.
Not certain of course, but the all-time could be under threat.

A bit of hysteria from the model generators I feel! Looks to me like at least a week of fine warm or hot weather for the south and east of Scotland & England, 25 - 32 C.
For the Pennine areas, Cumbria and Western Scotland more cloud at times with drizzly rain 15 - 20 C

The timing and peaks of this look like being uncannily like August 2003, but 2 days in advance, so it's worth running a day by day comparison. Yesterday was Friday 1 August - cloudy, with a high of 25C in the far SE (Manston that year if I recall). Today is Saturday 2nd August when in 2003 it reached 27C. We hit 30C on the Sunday.  


Arome is now in view and gives maxima of 26 or possibly 27C today, and 29-30C tomorrow.

The European record is now 48.8C in Syracuse, Sicily, on August 11 2021.

Met Office longer range forecasts have downplayed the heat somewhat, saying just "possibly hot".
Quite telling that.

Met Office longer range forecasts have dropped all reference to the word "hot".
Very telling that.

Check my edit. They've downplayed it to potentially hot.


Yesterday the word "potentially" wasn't in there IIRC.


Anyway, it's all semantics. 32c is plenty hot enough foe anyone.

Feels like the first evening of the heatwave here in SE London. 25C at the closest PWS at 8.50, 6C warmer than the same site at 2pm.
