Monday 15th September is Battle of Britain day when 'The Few' faced their greatest challenge.

A Polar maritime northwesterly airmass covers the British isles.

This airmass brings sunny spells and showers, some heavy; probably bright skies with lots of sunshine between the white cumulus and cumulonimbus cloud.

Polar maritime air is also associated with good visibility outside of the showers, although these can be heavy and thundery especially in the north and west.

It was breezy too, gusty winds around northern and western coasts.

A day which still brings much national pride and one in which the weather could be called typically British too; it certainly played its part!
