Saturday looks like it could be an April peach of a spring day for
much of England, South Wales and the SE of Scotland (maybe even
further North as Aberdeen). The first 21C of the year ought to be
achieved somewhere. I still stick by my 22.3C in Hurn as being the
location of April's max UK temp and Saturday looks the likeliest day
for it to be achieved! Maybe somewhere in the SE will beat it!

Make the best of it, for the last week of April and into early May
look unsettled and cool.
