The met office symbol forecasts are obsessed with the cloud symbol. They constantly overestimate or make it seem like it will be cloudier than it is!
I've noticed this, and posted an example in the SW thread yesterday.
Tomorrow they are forecasting sunny and 17c here though, and have more sunshine on other days this coming week too now. Typically I am meant to be travelling to the cloudier SE tomorrow though.

It's turned mostly sunny this afternoon, max temp 13.4c. According to the forecast it should be overcast though.. in fact I can't remember when the forecast was not cloudy each day.. but then the forecasts seem to overdo cloud, and even when some sun is forecast they often show a cloudy symbol for the day e.g. this for last Tuesday
No symbol during the daytime was 'cloudy' yet the summary smbol for the day was a cloudy symbol and you wouldn't know any sunshine was expected unless you clicked on the day to look in detail

Always manage to forget and be late.. may as well enter a guess, 9.1C

Is the weather ever decent in Aberdeen?

I thought they always used the 9am-9am meteorological day or 21:00-09:00 for minima because that's what was used before the times of automatic recording made it easier to record at midnight.
I presumed they keep it like that for consistency, otherwise you would not be able to compare max/min temp data to older records. Makes sense really.
In fact I thought it was the standard UK system for official stations?

Before anyone thinks about posting a certain image that you may have seen doing the rounds, have a peek at this: http://a4size-ska.deviantart.com/art/Eclipse-144235675
ITV fell for it, but have decided to take down the webpage.
Lol I saw that image several days ago

Went duller here in Egham like a dull december morning (all car lights on etc) but nothing else with thick north sea cloud.
Solar radiation graph from weather station at home shows a nice drop, though with mostly cloudy conditions:
(spikes significantly over theoretical max are due to reflections of other clouds while the sun's out)

Looks like clearing at home or providing a thin veil of high cloud helping you see the event, whereas here in Egham it's overcast of course

Still heading South.
Hmm if Moscow has/had good northern lights but is well south of them on that map..
unless they 'shift round' to an extent as the Earth rotates and they covered Moscow earlier, but still looks a tad far south.

I have. During the 1999 eclipse, the temperature dropped 5C and there was a strange chill and slight breeze.
I suspect any convection may weaken just after the height of the eclipse.
During an eclipse effecting North Europe (possibly 2008 though doesn't seem so long ago in my memory) I remember clearly seeing convective cumliform cloud weaken/decay over broad areas during/just after the passage of the shadow on Sat24.
During the 1999 eclipse I was 5 years old and was by the Avon Dam on south Dartmoor. I have a memory of it being cloudy and suddenly going dark.
Also I recently brought a solar radiation sensor for my weather station.. It will be interesting to see what it shows on the 20th.

A shame Autumn rarely arrives on the 6th of September and winter rarely arrives on the 6th of December, it must be so boring for mildies as they have the next 7 months to chase high pressure and warmth, winter only started 3 months ago but the chase for cold and snow has long been over, in 3 months time it will still only be June but mildies and joe public never seem get fed up of warmth and high pressure though, i wonder if coldies would get fed up of chasing cold and snow if there was a chance of it for 7-8 months a year
Maybe people interested in both/many weather types are lucky as they get to watch the weather all year round

Possible cooler, wetter Summer.
1976 looks like it had a pretty cool AMO

But still sunnier than average for most and much better than last year.
Interestingly last winter was quite sunny too for much of England despite being the wettest winter on record.
Just shows that Atlantic weather doesn't necessarily equal dull/grey weather.
This years high sunshine is thanks mainly to Atlantic PM flows.
As for September and the following winter, there are various supposed links probably due mainly to the the random/coincidental nature of statistics. There may be something to some of them, though if there is I doubt they are fail-proof. For September it could be that warmer Septembers are more likely to occur in warmer periods anyway and leave sea temperatures higher, though that could be overridden easily given the right synoptics.
Another interesting stat is the wettest Spring on record (1947) was also followed by the sunniest spring on record (1948)
-
7.5c please

N/W Devon getting a fair dose of lightning by the looks of it:

Fair bit of lightning in North/West Devon

Compared to some earlier posts I'd suggest it is still winter (ignoring the date), as despite some slightly above average max's and sunny days, we are still in the longest spell this winter without double figure-maxima on my weather station back home, and last night reached -4.1c.
Been sort of spring like the last couple of days here at uni, but not spring. The sunshine was a pleasant surprise though unfortunately it's just cloudy/dull today. Sunny/frosty highs are quite nice (though there's been limited frost here in Egham compared to back home recently but that's not unusual), though cloudy ones are a completely different ball game.
When spring arrives I wouldn't like a March 2013 either as that was just often cloudy,breezy and cold down here with little snow. I'd happily take an April 2011 style month with very warm weather and some thunder.
Ideally I'd prefer some colder interludes though, more early on like perhaps a cold northerly in March with snow showers, and a less homogeneous spring than last year, though if a spring is like that I'd prefer it to be homogeneously warm rather than homogeneously cold.

Looks like a lot of cloud in the forecast with this high.
I would rather a more mobile pattern like at times this winter that has brought reasonable sunshine and also frosts in PM airflows. At least there may be some interesting weather to keep my interest in weather going then, like there was last winter.
-
-3.9c at home in Devon last night so another decent frost.
Here in Egham it may have snowed earlier but I slept through it and nothing has settled.

After the confusion and some odd claims it caused it looks like the GFS is heading closer to the BBC's (and possibly ECM and others) way of a max near 6c for London on Thursday (1c out would be viewed as a successful forecast).
-
Yes,reputedly so,182 cm / 6 ft 1n 15 hours near Ashburton!
That is something I wouldn't mind witnessing!
Regarding this incident and overall here is a post from Philip Eden to the uk.sci.weather newsgroup from February 2005 - http://www.weather-banter.co.uk/uk-sci-weather-uk-weather/89828-boltshope-park-snow-4.html
Interesting thanks, always wondered if it was a true reading or whether it was slightly 'optimistic' reporting or measurement of drifts, as would have taken something pretty impressive.. (roughly 182mm water equivalent in 15 hours in a cold winter airmass? (assuming 1/10 ratio)).
-
It really has to come into question, 1c here all day and NOT 4-6c as predicted.....an absolute joke...almost propoganda?
Back to models, GFS now picking up on correct signal and seeing another trough set up over Scandi down the line?
such a good post by ANYWEATHER.......worth taking note
BFTP
Propaganda for what? The BBC city temps may be a little high at times, but here the maxima have been as forecast or a degree higher, today's 4.7c was the highest lowest of this spell (forecast 4c) I do think showers may be more wintry than they made it sound on the 6:30 forecast I saw though but I could be wrong.
I see uppers for Thursday of -7c on the ECM.. can't tell what the UKMO says, but I'm sure they would go with that over the good old GFS. GEM/JMA support the ECM.
GFS has a max of 4c at -9c uppers so...
To be honest, white I think the temps may be a touch high I am not sure why there is so much surprise from some experienced members, the centre of London will be one of the warmest locations.
I feel they tend to over-do night temps for some towns by showing 'centre of large city' temps, but when they do show countryside temps they tend to be nearer the mark for the colder spots.

Blimey had some snow! started as sleet and pretty wet throughout but nice big flakes that tried to lie in isolated spots, nice to see.
Parts of Cornwall like Falmouth/Newquay have beaten here of course though lol
Edit: the surrounding hills have a dusting!

I read somewhere that SE Dartmoor had a level fall of 6 feet once.. sounded like in one fall though not sure.
Think it may be in a book I had though without searching through it's hundreds of pages I don't know.
Edit: found a reference to it for February 1929 here http://www.neforum2.co.uk/ferryhillweather/bonacina.html
Not sure where 'Holne Chase' refers to, but the village of Holne is generally around 100-200m in the Dart Valley, though with much higher moorland nearby. Though if those amounts occurred higher up it could well have been substantial down to lower levels too..
I did hear it was potentially a record for relatively low levels in the UK (assuming that is actually a level depth not an incorrect measurement)

-0.7c with a frost this morning, and since then a glorious day with a high so far of 18.9c. If we reach 19.3c that will be a diurnal range of 20c.
