Dewpoint's still 17C here Will, in fact Penzance heliport's reporting
a dewpoint of 18C. Force 4 SW breeze taking the edge off the
humidity. Temperature currently just over 20C (11:15). Last nights
minimum thankfully lower at 15.0C. Mainly clear skies over the sea,
small/medium cumulus readily form over the land.

Definitely 'feels' different today but as you say dew points haven't fallen that much (Exeter currently 14C v 16C this time yesterday). I suspect the marked changed will come post cold front on Sunday which introduces theta-w's of around 10-12 more generally compared to the current values of around 14-16.
