My first 20C day today at 24.5C, easily beating the previous
record (from yesterday) of 18.3C.

Now this got me thinking, there must have been a fair number
of places in the country today whose first 20C day was also
their first 25C day. Now to me this seams like a statistically
rather unlikey feat but perhaps it's more common than I
might imagine. Is there any data on this interesting (though
admittedly rather obscure) event?

An interesting one, Col. Today was the first day in Chalfont St Giles
this year that exceeded 19.9C. The max today was 28.3C.
