I have to confess that I misled Colin about the Leconfield max - as some may have seen from elsewhere, the max transmitted is 26.6C making it the warmest place in the UK.    I wrote it as 25.6C by mistake because Hull was 25.5C. Hull is a warm site so this high max at Leconfield seems rather surprising (that's my excuse anyway!).  We have to go with 26.6 unless we hear otherwise.

As you may have seen if you watched the BBC weather at 1030pm, the Leconfield temp was rounded up to 27C - the highest hourly temp was <25C so there must have been a large spike there, tho' this sometimes does happen  - this kind of thing results in considerable debate between Colin and myself!     I remain surprised because the Hull site is slightly sheltered and on the warm side as a result.

A informative PS from twitter later last night.     The Met office tweeted the temperature, were then asked about the max, MO tweet staff then informed us that the max occurred at 11 minutes past the hour (I think it was 2pm).  The preceding SYNOP was only 24.9C, the equal highest hourly of the day.   If you follow the right people, twitter is the place for useful weather information now.  (it is  big IF, I know  :)  )
