I was going to ask where all this moisture has come from, seeing that we
have an easterly flow, it's not been especially wet in the past few days and
the sea's not even 15C.

The SST is 16C off Cornwall now http://www.channelcoast.org/data_man...arts/?chart=75
There are some really warm patches of water even several miles out
(E.g. 62f out at Sevenstones this afternoon)

Although the flow is easterly, didn't the air originate behind a warm
front which went around the top of the high?
