Hi Jon,

That must have been a particularly wetting CB because it resulted in their
dewpoint temperature becoming higher than the dry bulb ("10/11" in METAR).
By
my reckoning, this gives an RH of.......
105% (approx)

Nigel.

There was a rainbow over Hurn as seen from Wimborne about an hour ago, say
8pm. Could the pot of gold at the end of the rainbow have affected the
readings
in some way?

Cheers, Alastair.
