Just reading some of the posts on here - There will be some implications for winter this year with the colder than normal Atlantic water in such close proximity.

0C at humberside is pretty impressive.

13.9c here at 1pm on 26th July takes some doing. It's not even raining at the moment.

This is about as exciting as it gets in high summer for cold weather fans like me - temperatures at 1PM of just 11C in parts of southern England in late July is amazing, a good 10C or more below where it should be at this time of day!

It's just as amazing as that 36C was, albeit at completely opposite ends of the spectrum. It did reach 18C here before the rain started and since then it's been pegged at 13C or 14C... which, although it would be well above average, is certainly possible on a January or February afternoon.

It's fascinating.


I wonder if these very low day maxima are a direct response to the very low atlantic SST's ?

If anything the cold pool seems to be getting bigger to which, surely it is bound to have implications for the coming Autumn and Winter ahead.

...then you can get some unusually low maxima in summer, or late spring. There was that late May spell in 2006, for example, with single-figure maxima widely across southern England, caused by the sun being blotted out by thick cloud. The thing is it's really very hard to get a whole day down here from May to July where the sun is blocked throughout - it's a good 16 hours or so of cloud that you need!


When it does happen, though, the results can be amazing. Indeed, I'd wager it's the only way to get highs that are 8C or more below average for the time of year in May to July (and probably August too).

I do wonder whether the enhanced thermal gradient to our WSW will cause more in the way of intense lows later in the summer and into autumn - we'll see soon enough.


In the meantime, it's a good time for folks to make sure their central heating system still works.. best test it now rather than when it's really needed later on!

So if we went 10c below average across southern England in January, would give us maximum's of around -7c?

Funnily enough, the sort of thing that happened on several occasions in the 80s and 90s, but since the turn of the millennium they've become almost extinct (certainly here, as the coldest maximum since 1997 has been -1.0C, as part of December 2010).


It's been a long time since those sorts of winter days with crisp sunshine and subzero maximas, the ones in 2010 here coincided with thick cloud and cold air aloft... not entirely dissimilar to the current setup!

It will sure make a refreshing change to be looking for endless opportunities from the atlantic rather than getting fixated on relatively dry and cold northerlies or even rarer easterlies.

Re. the Atlantic. I think it'll warm again over the coming few years, but once we get into the 2020's the cold AMO should really start to "bed in" and become quite common next decade...
