Ensembles looking like a change is on the way for the second half of the month maybe? Very little rain signal in the latter part of the GFS down here.

Indeed, later on only just a few runs with rainfall but keep watching, those wet runs have large amounts. The synoptics also suggesting a warm BH weekend though ens yet to come on board for anything exceptional.

In the meantime, the fax chart for Wednesday looks really wet for England and Wales (hope the Scottish border gets spared - they're having more than enough at the moment while it's still quite dry here) and the depression on Sunday next looks a certainty, though it's location varies between GFS (N of Scotland) and ECM (from NI into England)

GEFS seem to be spotting another heatwave in about 10 to 13 days time. It's very good at this with both the late June and July heat it started picking it up at about the same time out. Here's hoping.

I only hope that if there is another heatwave, it lasts a bit longer and does not contain the awful humidity that the late July one did.

Makes me wonder if we're heading for the September banker. At the moment it looks like more settled weather will return later this month and as we've seen in recent years September is often more akin to a continuation of the summer than the start of the autumn.

No, it is actually factually incorrect regardless of whether you agree or not. The outlook shown at the end of July was generally unsettled but warm. The unsettled weather was mostly for the northern half of the country but affecting all areas at times. Not my opinion and people can check if they wish.

The current outlook shows things warming back up again after the cooler few days coming up. With a predominantly SWly or westerly flow in the midterm I would expect the regions that normally do well in such a setup to have some pretty decent weather at times but areas to the NW to be less fortunate.

Up here tomorrow t850s are expected to be about 7°C below average and about 5°C below in the south, however how that translates to surface/t2m values is a different matter. Some sunshine and light winds or cloud and rain will outweigh that.

 I am afraid having a heatwave and pleasant low humidity in the U.K. is rather having your cake and eating it.

We manged it last year. Even though the period from early/mid-May through to almost the end of July last year was very warm/hot, I recall little by way of really humid weather and certainly not in the same abundance as has been the case in the past few weeks.

I found the humidity levels over the entirety of this summer to be particularly woeful.

Again there are tentative signs of more settled conditions towards the final third of the month on the 12z output so far (GFS/GEM)

I’m keeping an eye on Wednesday, surely a good chance of more gales never mind the copious rainfall for some areas. Something to watch IMO.

Much the same outlook as yesterday. LP dominating this week, with centres near UK on Wed (England), Sun (off N Sctland, GFS; further S and deeper, ECM). ECM also brings up a further LP from the west next week.

GFS  0z suggests a pulse of warm air and HP for the end of the BH weekend, but the ensembles are literally lukewarm on this.

There are hints of High pressure in the models, especially for Bank Holiday, I know a bit far out. Also on some models the N. Blocking easing off.

Agreed. The disturbed weather continuing for a week or so, but with next weekend's depression arriving a bit sooner (i.e. Friday) that was originally forecast. For the BH weekend, distinctly warmer though only a few runs go as far as hot; and drier, especially in the south. ECM has something of a thundery low over France just before that (T+240) which needs watching

Signs of drier weather later this month and still some very warm runs appearing. Before then it's a mixed picture.

PS: I changed the scripts yesterday so the GFS op is plotted at 6 rather than 12 hour intervals. Doesn't make a a lot of difference but the charts look a little smoother.

I'm pleased to see that, despite the unseasonable weather, at least the snow row count is still zero!

This is the link to keep an eye on.  Nothing since June 10th. How much longer can that continue for?

6Z GFS op run gets increasingly warm/hot in the south towards the end, although not a huge amount of support from the GEFS.
