Was it Polar maritime or Arctic Maritime air today?
Half and half if you ask me.
Lots and lots of showers here. More than usual for a polar maritime , but really not that cold.
max 6.8C
min 3.2C
rain to 1800Z 6.5 mm.

A good amount of instability which goes with cold air over relatively warm sea, suggesting more Polar maritime than Arctic Maritime. I think the Arctic Maritime digs in over the weekend with less in the way of showers.
