What is the warmest April?

I think you made a mistake (i've fixed it for you )

80 farenheit = 26.7C I'm guessing that it will be breached in the second week of May in the London area.

The sun is powering through the haze, so I think the temperatures should start to rocket now :lol:

It's been raining here since 21:30 - light to moderate at the moment Looks like there's some heavy stuff coming my way :unsure:

http://www.meteox.co.uk/h.aspx?r=&jaar...;soort=loop1uur The storms appear to be building in from Belgium.

They always seem to do that on the London buses - is it too much to ask for them to turn off the heating during mid summer!!

With the human race altering ever increasing amounts of the Earth's surface, I have always wondered if the urban heat island effect could be affecting global temperatures. Take London as an example - on satellite photos it never fails to amaze me how massive the urban area actually is. The fact that we can see London from space shows just how significant it is. Now take all the other major urban areas, roads, and other man made surfaces, and you can see the big picture. Surely all of this across the entire planet acts as a massive central heating system, absorbing an increased amount of solar energy and radiating it out. Is it not conceivable that our altering of the planets surface is sufficient to have caused the rise in global temperatures? It would be interesting if someone could post figures of percentage land use across the U.K. - could someone calculate the percentage of the land area covered in tarmac/concrete? If my theory is in any way plausible, then perhaps global temperature could be correlated against world population or total developed land area.

It looks like we won't get any at all here in the south east, despite what this mornings forecast said. It seems that the rain has broken up in the HP and milder air.

Hottest day of the year today. Has anyone surpassed 20C yet? is it likely to happen any time soon?

Temps got up to 19C here now despite a rather hazy sky and brisk wind. http://www.metoffice.gov.uk/weather/uk/obs...ions/index.html All you northerners just scroll to the bottom and be jealous

Has anyone seen the latest rainfall radar?: http://www.metoffice.gov.uk/weather/uk/radar/index.html I don't think i've ever seen such a large area showing up as the 'downpour' category! Any Scots around able to comment on the conditions?

Whenever I see these maps, I always wonder how there could be so much ice off the eastern Danish coast - is this just a radar error or does all this ice actually exist. If so, how - I doubt it could have just formed there seeing as its not been particularly cold there. Or has it somehow drifted from the northern baltic? any ideas?

It certainly has been very dry here - the ground has been rock solid for weeks, in fact, when the winds picked up earlier, there was a bit of a dust storm around here. The ground is now soaked after the heavier than expected showers.

Certainly very cold up there - the forecast suggests temperatures hovering around -20C for the rest of the week!

Has anyone got the latest value or perhaps a link to the data?

I love the fourth one - the tree is in the perfect position (1 third rule) and it casts an excellent silhouette. The colours are stunning also. Just out of interest, what camera did you use and did you use any filters/lenses etc?

I'm hoping that we get very low rainfall totals from now until the end of summer so that any sunny weather will actually be hot (with the dry ground). A nice hot April would be welcome with perhaps the chance of a 30C in London (although I doubt that seeing as the record is 26 I think). To be honest i'd be happy if we had a 1030mb+ ridge of high pressure sitting over us for the next 6 months. I personally don't mind record breaking heat as it's certainly much nicer than a washout.

wow, those are stunning! They really look like tornado pictures from the North American prairies.

Snowy hail showers have just started moving in to London edit: from a visual perspective, it looks like there's some decent convection taking place - all I can see on the metoffice radar are a number of small blips. Anyways, some nice looking anvil clouds moving in.

It has been a day of contrast today: The first half of the day was mild and sunny with scattered clouds. After noon, the cloud quickly built up from the west and at around 2 it started raining and the wind picked up. Shortly after we had sleety rain/light snow which turned to very heavy hail 30 minutes later. .....and now..... back to sunny spells :wub:

5.7C bang on the old average

Just a suggestion that the Spanish weather stations that you have quoted are at higher altitudes relative to those in the other countries. As upper air takes longer to change temperature this could be an explanation - perhaps a more experience member could prove me right/wrong on this.

There appears to have been a sudden rapid loss of half a million square kilometres in the last few days - any reason for this/weather events? I think I heard something about record temperatures on the east Asian coast so perhaps these may have spread up to the Arctic to one of the areas where melting appears to have ocurred - between East Siberia and Alaska. The below map illustrates it best The main areas of break up appear to be: West Hudson with a smaller break up in the southern area. Southeastern coast of Victoria Island (possibly linked to Hudson) The large bay North of Japan's north island (i don't know the name) A N-S strip on the far east coast of Siberia Newfoundland A large area between Svalbard and Novaya Zemlya Note - The bold coloured line represents the average extent for the particular time of year. Just for a comparison, here is the state of the Arctic at the end of January.

TBH it doesn't really matter that the data is processed in Exeter - as long as the weather stations in Scotland are in good order then there is no reason to spend millions on another supercomputer if there is already one available.
