Further on into this GFS and nature is healing.


Is there any more “average” summer chart than this?

That trough really is hugging the Channel like a limpet isn’t it? Poor Moomin.

And yes, apologies for the off topic posts but it’s very interesting. 🙂

High pressure by itself in a location close to the U.K. does not necessarily mean dry, hot and sunny weather in summer, as much as many of us would like it to.

Still they are wrong and misleading to show no clear LP cell over the channel like the channel lows does.  They need to take down the fake HP charts and put LP clearly shown.  That set-up before always deliver sunny warm to hot weather days nationwide.

Before LeedsLad comes on and whips us all into shape, I can pretty confidently say Manchester is wetter than Leeds (certainly in terms of rain days, not sure about actual rainfall).


Leeds’s figures are misrepresented from the Bingley weather station which is 200m up in the Pennines - for Leeds itself you’d be better off using Church Fenton which is much much drier. 


Manchester (Woodford) is also wetter than Liverpool (Crosby) but not by much.

The west and northwest suburbs are much wetter than the centre and east. But even that doesnt tell the whole story. I'm from Otley and just over the hill by about 4 miles is Yeadon. The difference in rainfall and temperature has to be seen and felt on some days to be believed. Microclimates are fascinating beasties! Two overcoats colder and  a sturdy pair of boots wetter in Yeadon!

Woodford and Bradford Lister Park average about 870mm, so I would say Manchester and Bradford are similar in terms of rainfall and Leeds dryer.  As Bow Echo says big variations. Under 600mm in the Vale of York, go west and it is over 1050mm at Bingley. Central Leeds may be 700mm at a guess . Hard to predict what it should be here given the gradients on the maps, but I am exposed and to the NW . Last year I did a full years measurements and recorded 1042mm , but it was a very wet year. I will continue to build up measurements.


 


Anyway looks fairly dry on ECM and GFS for the next week here, GFS more so as some of the stuff in the South moves up here on ECM.  Overall though, the nice useable weather looks likely to continue after a poor day today.

I know it’s extremely frustrating I’m a heat fan in summer I’m also a strong believer in  that things eventually even out.


let’s hope sunny and hot conditions return soon, of course if it’s your desired outcome.

This situation is analagous to those in winter where we almost have the classic coldies set up only for it to scuppered by an otherwise insignificant shortwave. Shame that little cold pool can't scarper as quickly as it dropped down on us from Iceland instead of hanging around like a wasp at a picnic. Paradoxically, here in North Somerset June so far has been quite dry compared with other areas of the South and it remains to be seen whether this area at least gets much rain over the coming days.

WX maaps show a bit of warmth creeping into he S by week 2, but a lot of rain there first and not exactly dry later. The W getting more rain in week 2 - eastern France and Germanygetting a real soaking  over the next two weeks


FAX keeping that trough over or close to S England to end of run Wed and (despite Jiries' claims) HP only starts nosing in on Wed and then mainly to Scotland. After a lot of uncertainty in the models about tomorrow' s rain, it looks as if there will  be a double dose, a line moving N tonight and fading except that it never leaves the far SW, and a second thindery batch late afternoon coming across the central Channel.[MetO rainfall map]


GFS matches FAX, the HP slowly taking over after Wed 30th but takeover not complete until Sat 3rd (and even then the green circle of doom is still not far away, o the French/German border) It doesn't last as shallow troughs move E-ward from Atlantic Mon 5th 1005 mb N Sea and Sat 10th 1005 mb Ireland with ridge of HP between. The promised W-ly pattern is only there by Mon 12th, with quite a large temp gradient N-S


GEFS In the S, mean temps near norm throughout (serious variation from Mon 5th with several very warm runs appearing) and frequent rain, some runs with big totals,  not relaxing until around Mon 12th. In the N, temps consistently above norm, cooling a little from Sat 10th, and no rain until Sun 4th after which moderate amounts


ECM delays the breakdown of next weekend's HP with LP moving N to Iceland before extending a trough in the direction of UK Tue  6th

Thanks Dew much appreciated, I would expect a met office warning for Rainfall for southern districts soon for Tuesday thats a large amount of rainfall in a short period.

A significant rain event next week at some point possible.  Other than that GEFS looks pretty reasonable.
