Here comes summer

Seven weeks of below average temperatures and frequent rain are about to end at the start of this week as warm air floods in from The Continent and pressure rises.
We should see temperatures above 20C by mid-week.

Interesting comment at the end of this BBC forecast hinting at a quite prolonged fine spell.
I have seen an observation elsewhere that the present situation shows similarities to the start of summer 1976. At least we've had a good top up of water in advance!
