I just posted separately before your one came through - I wonder what can
be
done about this?

Brian, you can record (for your own purposes) a max/min at 2100
which will then allow you to tabulate a "day max" and a "night min"
as well as the "official" figures.

A similar problem, of course, arises when warm air comes in
overnight after a particularly cold day.
