That's enough for me. 5 gfs runs with agreement from the ECM leads me
to a 10-day forecast.

**At T240, on Valentine's Day, the UK will still be in the grip of a
cold spell. There will be snow lying in some areas of lowland Britain
and that snow will have been on the ground for some time, causing
disruption and travel problems. On the 14th, the wind direction will
be from a continental, or a northern source and temperatures across
much of Britain will be below average.**

Well there you go. That, for me, is the probable outcome of 5 days of
some of the most interesting model watching of recent years. Dig out
the thermals, we've got a week of cold coming, starting at the end of
the weekend.
