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-whttp://meteocentre.com/models/ukmet_eur_00/ukmetTW_00_panel.gif

Cloud's fairly well broken in Penzance at the moment, (20:40) and
there seems to be less low cloud south of Ireland now, so I'm hoping
for some spells of sunshine along sheltered parts of the south coast
of west Cornwall tomorrow. If so it'll probably causing a mass exodus
of holiday makers from the north to south coast of Cornwall around
lunchtime.
