An intriguing image of what appears to be a fog bubble on the BBC Weather Watchers website yesterday. My theory is that it’s someone who has been in the shower for a bit too long who has left the bathroom window open, or some mad scientist with a tank of frozen nitrogen having a bit of fun. The BBC Weather website has other, far less audacious ideas about the cause.
Rather bizarrely the Met Office finally did get round to issuing a fog warning at 1546 UTC this afternoon, even though visibilities had been less than 100 M all day in the areas that the warning was intended for. It seems to me that someone else is reading these missives of mine other than my 23 regular subscribers…
- Fog in the southwest slow to clear
- How thick does fog have to get before a warning is issued by the Met Office?
- The biggest fog patch that you ever likely to see
- First glimpse of the sun…
Here for example are today’s observations from Yeovilton. The visibility was no better than 200 M all day and the maximum temperature was only +0.6°C, so for much of the time the fog could have been freezing.
These observations from as close as 3 miles away at Exeter airport show how visibilities had been reported by the AWS as 100 M since 0900 UTC in the morning, ironically they improved at 1600 UTC as the warning was finally issued.Meanwhile at Chivenor in North Devon they had also had been reporting fog since 0500 which persisted all day with visibilities 100 M or less for much of that time.
I don’t know what’s going on at these places but surely the aviation bench must have been pushing out TAF’s in the southwest with fog in them and issuing warnings to various authorities, obviously forecasters don’t do much in the way of interacting or looking out the window these days. The fog didn’t need to thicken up I’m afraid, it had been there all day in Devon, Somerset and west Dorset.
According to Ben Rich and Holly Green on the BBC TV weather at lunchtime, this big blob over Dorset, Somerset and East Devon is just a fog patch, well you could have fooled me! Here are the latest observations from 1400 UTC, I would suggest if it’s not budged all day, and as it’s now 1500 UTC, it might even thicken up a bit, not that I want to tell you how to do your jobs that is.
If anything this morning’s fog has become a lot more widespread over Dorset and Somerset, and as temperatures are still sub-zero at places such as Yeovilton, it could still be of the freezing variety. In East Devon the fog has thickened up as the temperature went above zero, and the visibility at 1230 was probably around 200 metres with the sky obscured. A quick walk up to the Beacon (our local viewpoint at ~215 M) revealed that the inversion here at that time must have been at the 600 feet level, although it was a fuzzy rather than a sharp inversion if the makes sense, but the sun was shining from a lovely blue sky.
I’ve just been watching Ben Rich on the BBC TV forecast at 12.57 PM, and obviously he can do the weather forecast without looking at the latest observations or satellite imagery, because he never even mentioned that Exeter airport (-0.3°C and 100M) and Yeovilton (-1.4°C and 50M) are still in fog – quite incredible! He did manage to say in his intro though that he was a Weather Forecaster, and as far as they were concerned, today was the start of meteorological winter.
No blackfrost this morning in Bradninch, just fog and a hoar frost as temperatures dipped to -3.6°C overnight. The fog is very easy to pick out in this visible satellite image filling the Exe and Culm valleys, there’s also a strange patch of stratocumulus over Cornwall, where did that come from? Here are the overnight [18-06] minimums from this morning’s SYNOP reports.
I’ve just come back from walking back four miles from Killerton (were my wife dropped me off on her way to work) back to Bradninch. I made the effort because on Monday I started the Michael Mosley’s 8-week blood sugar diet in an effort to stave off the onset of type 2 diabetes and reset my system.
I have left myself go since retiring and live an almost totally sedentary lifestyle with very little exercise. I weighed in at 16-12 on Monday morning and this morning checked the scales again to find I was 16-4¼ so that’s almost 8 pounds in 4 days – and yes I know – that’s just likely to be all fluids rather than fat. The diet is pretty strict and 800 calories is the daily limit with a heavy emphasis on low carbs and a Mediterranean style of foods. I’ve done other low-fat calorie counting diets before and they can last a year or more, what I like about this one is although its severe it’s also quick, and the health benefits are enormous, because type 2 diabetes is a nasty disease to be afflicted with especially when it’s totally avoidable as the book makes clear. I would urge any of my readers (and that means all 12 of you) to investigate the Mosley diet if you are carrying more weight than you should, get your blood sugar tested at the doctors, you might already be pre diabetic or even type 2 diabetic and you don’t even know it, but the good thing is that you can still change things.
Anyway enough of the preaching…
I could have included more photo’s of my walk but as Sods law would have it, the battery in my camera conked out and I wasn’t carrying a spare! And wouldn’t you know it, immediately after that the sun burst through the trees with shafts of orange light piercing the mist, and a Barn owl swooped towards me. Well I added that bit about the Barn owl but the rest is true. The trees don’t get their autumn colours till a lot later down here, November is the month that trees shed their leaves rather than October, but a few have started to turn, like this one.
