RMK: RR yesterday 4.6mm from waving front at around 17Z. Tx 20.6c quite
early on at 10z.
Not sure where todays 0.3mm has come from. probably a bird jumping on the
guage.

I noticed that there was an exceptionally heavy dew for the time of year
this morning. Could that be the explanation?

Yes, John and Phil, the same here in Wokingham, 0.2 mm on the TBR overnight
and also a steady drip into the TSR between midnight and 04z. I guess that
the relatively warm soil, now wet from yesterday's rain, kept the air near
the ground close to saturation by evaporation, with a steady 4 to 6 knots at
10 m providing enough mixing to prevent fog. Objects cooled by radiation
immersed in this will collect plenty of condensation.
