Surprised at this.... Yesterday I was around 35 miles from Romsey
during the day, taking a day off after working all weekend, in the
Fernhurst area of West Sussex (15 miles N of Chichester). Warm, fair
becoming sunny, some cumulus around but never anything threatening.
Saw some bigger cumulus due south (Chichester area) but never any
anvils to the southwest.
