Another sunny day. Ci invading the sky this afternoon in striking
parallel bands with a hooked structure at the head of each band.
My best description of this cloud would be Ci uncinus radiatus.
The sea breeze has struggled to initiate today, allowing the
air temperature to rise to its highest value of the year to date.
RH 62%. Wind currently WSW force 3. Max temp so far today 21.1
