So it appears that this is going to become a summer of very different
opinions depending on where you are. It's probably only very small areas of the S.E that have had the constant high temperatures and dry weather since the beginning of June. It hasn't been particularly more sunny than usual, just a bit above average. You don't have to go far to the North and West of here either to get more "normal" conditions. Can't say I've noticed a S.E bias on the reporting either. All I seem to hear on the forecasts is "more rain and showers on the way" ! Dave |

I think you can go quite far west, as long as you keep well south of the M4,
as far as Exeter to find things have been (overall) sunny, dry and warm. Averages & totals so far this summer (1st June to 6th Aug) Min 12.0°C Max 22.8°C Mean 17.4°C Rain 103.9 mm Sun 552 hours The rainfall total, whilst being a little above the average paints a different story when you realise that most of that total has fallen on just a few days leading to very long, dry spells. The soils around here have remained dry throughout the summer. Even after a heavy spell of rain, a couple of days later everything is dry again. The weather has been quite good for the Sidmouth Folk Week which ended yesterday evening. The camping fields around the town are all dust dry. Certainly not as hot as 2006 (so far) though August (mean 17.0°C) wasn't up to much with generally unsettled and cool days. If this August turns out to be a good one, then this summer could end up warmer, drier and sunnier than 2006. _____________________ Nick Otter Valley, Devon 83 m amsl http://www.ottervalley.co.uk |

Quite a number seem to have gone over this month, but only 4.8mm has fallen so far, with a fair amount of sunshine inbetween. It's also been slightly warmer than the 1st week in July. I think the 2nd week in July saw the poorest weather of the summer here. Today, thin patchy cloud, main sc, with good sunny spells inbetween. 19.8c @ 12:45. Graham Penzance |

have gone over this month, but only 4.8mm has fallen so far, with a fair amount of sunshine inbetween. Aye Graham, when I've looked at the Met Office charts for this summer and they've shown weather front after weather front passing over but apart from a bit of cloud build up, you would not have known they were there. The worst part of July for here was (and the only really unsettled weather of the month) from the 13th to the 17th but apart from the 13th (coldest day of the month with 19.6°C), all those days still managed 21°C, such was the consistent warmth (but not heat) of the whole month. Sunshine now after a short sharp shower. _____________________ Nick Otter Valley, Devon 83 m amsl http://www.ottervalley.co.uk |

Here in NW Oxfordshire, and defined as being within the Midlands as far as Met Office UK climatology is concerned, it has, so far, been the third warmest summer since 1995, (only 2003 & 2006 were warmer). However, the lack of summer rain has been more noteworthy. Total rainfall for June & July at only 37.3mm make it the driest two such summer months since 1995, and so far this August has only added another 1.9mm. I don't record sunshine, but looking at the Met Office anomaly maps it has been close to average overall, slightly above in June, but a little below normal last month.

Most summer fronts are of the split variety. This has been the case this year with one or two notable exceptions. A split cold front is where an upper front runs ahead producing precip. aloft which can evaporate before reaching the ground. The surface front is very weak being just a band of cloud and patchy rain but marking the surface transition to cooler air. In between is a shallow moist zone of cloudy drizzly conditions. Occasionally a jet streak will overrun the shallow moist zone and, with added vorticity, increasing instability leading to heavy rain and sometimes thunder. This has happened a few times this summer. It looks like magic when models do that as rain seems to come from nowhere in an otherwise weak frontal system, but it is all well understood 20th Century science. The term "weather front" is a massive simplification. There are many many types of front. Will -- |
