Quite true. What’s left of the ‘plunge’ from the north on Sunday/Monday is still 5 days away yet, and as you say it’s not beyond the realms that low to the south may play ball to our advantage in some way.
I would not call it experience, but just viewing charts for 25 years plus says however our dominant wind direction normally has the biggest say in the end.
That’s why I prefer, certainly for here a wind from the east without any southern low intervention.
Yesterday surprisingly delivered a little more than I expected.
