I find this a very curious chart from the ECM this evening. A slack low smack bang over the country, yet very in the little if anything in the way of heavy showers, which such a pattern would normally bring at this time of year.
Is it because the ground is so dry now that there is no moisture to be evaporated to big up some rain potential? The next day has a similar pattern, but with a few light showers around. Nothing that would be of any use to anybody.New Moon

Interesting that there were no outstanding summers in the 1960s.Mullaghteelin wrote: »1990 possibly? I have a vague memory of it hitting 32C in the Dublin area in early August.sryanbruen wrote: »There used to be a PDF by Met Éireann ...
Cheers, thanks for all the answers.
That’s a pity that that met document was taken down but hopefully it’s not totally gone.
It is interesting that nobody has memory or data of a heatwave in the 1960’s. That’s borderline incredible if it turns out to be true (some of the monkey deities must have been angry about all the free love and LSD in them times
)
There’s a lot of agreement so far even about long ago eg. Jul 1955.
I’ll tot up a total & near total over the next few days.
Disappointing that 32.5C wasn’t broken this event but this summer looks like it has plenty of firepower left yet.0 -

The models are differing on how quickly the occluded front approaches the W on Sat with a trough ahead of it by evening. Met Eireann saying showers possible in the NW later. It looks a very weak front.
The American models showing rain ( possible thunderstorms ) the European showing very little rain if any.

It's just a surface heat low, formed by the heating of the airmass over the land. These are common in the warm season, and Iberia has one most days. If you look at the hourly Met.ie mesoscale charts you can see the low forming hour-by-hour during the morning, peaking by late afternoon, then filling again overnight. At higher levels, however, there is actually a high. Look at 925, 850, 500 hPa charts, etc.0 -

With the way 2018 is going we will probably have supercells approaching the south coast tomorrow night0 -

The 1960s decade was known for its poor Summers and cold Winters. The "decent" Summers didn't occur 'til the last two of the decade, 1968 and 1969. These Summers for Ireland stand out for how sunny they were, especially 1968 in the northwest. However, they weren't remarkable at all for warmth and 1968 was in fact quite a cool Summer which is strange because usually dry and cool Summers would be rather dull.
I have not looked at 1969 in detail yet bar the fact that it was quite a sunny Summer (with more than 600 hours of sunshine) at Dublin Airport.
There weren't any heatwaves in the 1960s that I know of.Photography site - https://sryanbruenphoto.com/
