Could see a return of the Pembrokeshire dangler..

... Someone could write a useful segment in the FAQ to describe this
phenomenon - we've got the 'Bartlett High' after all! Someone's bound
to ask what the "Pembrokeshire dangler" is.

Yes, it often amazes me what a narrow intense band it is. Often
described in forecasts as a 'Line of showers' , but it's often
anything but showers. It rains, often heavily, for hours on end.

The last marked occasion was occasion was 14th December, when I had
around 23mm of rain/sleet, whilst the just 10 miles to the east it was
dry much of the day, I could often see blue sky through the rain to
the east. That occasion was atypical, as the feature was quite weak
leaving Pembroke, but intensified considerably when the flow was
disrupted by the Land's End peninsula.

The wind direction is critical, virtually due north for here. A slight
backing and the feature moves east towards Devon and weakens steadily
as it does so, a slight veer and Scilly gets a real pasting.
