UPDATE at 6pm Friday 31st August
Last night was the coldest August night on record at Leeming (1.1C, records to 1945) and Bradford Lister Park (2.8C, records to 1908).
Summer at Leeming was the fourth wettest, and the dullest on record.
At Sheffield Weston Park it was also the fourth wettest summer in records which date back to 1882, with 2007, 1912 and 1956 all wetter than this summer.
The Met Office have said that summer 2012 will be the second wettest (summer is June, July and August combined for statistical purposes) on record across England and the UK as a whole, using rainfall data back to 1910.
So far 367mm of rain has fallen, compared with 384mm which was recorded in 1912.
It's also been the dullest summer since 1980, and cool, with mean temperatures 0.4C below average,
It adds to a depressing sequence of summers across the country, with the last 6 years all being wetter than average.
Moreover 2 of the 3 wettest summers on record have happened in that time - 2007 and 2012.
The reason for our poor summers is the jet stream.
It's been consistently too far south over the last few years, and is the reason why we've experienced some cold winters recently, too.
The big question is why is the jet stream behaving in this way?
There are two current theories, which I detailed in my earlier blog which you can read here.
One is linked to melting Arctic ice, which fell to a satellite record low on Monday.
The other theory suggests it's down to the protracted low solar activity over the last few years, as happened in the early 1800's.
And if the early 1800's are anything to go by, poor summers and cold winters may be something we need to get used to in the next few years.
