Dewpoint 16.5C, air temperature currently 19.8C following a few bursts
of sunshine when it reached 20.2C. Light wind so feeling very, very
muggy, a warm night ahead. Ideal conditions for raising the SST
though.


Felt muggy over my way too, Graham, with Exeter now reporting a dew point of
17C (air temp 19C).

A plume of high theta-w air (16+) is advecting east so air temperatures are
likely to be even higher tomorrow assuming a decent amount of insolation to
the lee of high ground across southern areas. 00Z MetO GM theta-w
