An unstable northerly over a still warm sea and Wednesday night
The 1st dangler of the season coming up? They can occur at other times, but the most intense ones are October-January when the sea is at it's warmest relative to the air.
Sometimes almost continuous rain / hail over a narrow band of west Cornwall rather than the 'coastal showers' term. Something to watch out for.
Interesting, attractive sky this morning, from Pz prom. I'll let somebody else classify it (also some big Cb anvils)
Always interesting the weather.

. . and here it is
The western edge tends to be much sharper than the eastern, which is more affected by the Cornwall land mass.
08:00
09:00
Spot the difference. 5mm in the last 2 hours here in Penzance, near the western edge so wetter just to the east. Nice blue skies 8 miles west at Sennen.
The models do a very good job at predicting the phenomenon these days. Shame forecasters insist on saying 'scattered showers' when it's a narrow almost stationary band of often heavy rain with embedded hail giving large amounts in an area often only 5-10 miles wide. Non stop rain here since before 7am and currently chucking down, like night outside.
Meanwhile just 8 miles west
Under the dangler (western edge) at St Ives.
The western edge tends to be much sharper than the eastern, which is more affected by the Cornwall land mass.
