A remarkable day of hazy then strong spring sunshine.  A noteworthy early May high of 21.9c at 13.22 with an easterly wind (45 mile sea track) indicates that if the wind backs to SE then a track of 21 miles from continental Europe  will open the floodgates to even less modification - expect 27c to be reached somewhere in the London region this weekend if the sun stays out for a good length of time.  Currently 16.7c.  59% humidity.
