After a chilly clear night, min of 3.8C in Penzance, the thin patchy Sc quickly broke in the morning.
The temperature in the Spring sunshine rose steadily to 11C by noon, by which time the whole Cornwall was basically clear of cloud. The gradient wind was ESE, but a sea breeze set in on both coasts so by 13:00 it was NE at Camborne, and quite a stiff SE at Penzance. In fact @ 14:00:-
Camborne NNE 14mph (mean speed)
Penzance SE approx 15mph.
This led to rapid Cu development along the convergence zone, in fact it briefly looked rather threatening over the moors. The basically stable air meant it quickly spread out though, and drifted away westwards as the temperature (and sea breeze) dropped under the cloud. The spreading and dissipating cloud did affect Penzance for a while between around 14:00 & 16:00.
It didn't stop it being a lovely day on many beaches. I mean take a look, busy as many days in Summer

http://www.sennen-cove.com/lbtdy.htm Lucky the lifeguards were on with low tide rips. There's a huge amount of sand, relative to normal, near the low tide mark at Sennen at the moment.
Day out at Porthgwarra tomorrow, then Bedfordshire (England) the day after. Still, back on the sleeper Weds night, so I'm sure I'll cope for 2 days.
