If the Boxing Day GFS forecast turns out to be correct, someone may be
turning the weather machine up to 11!

The ECMWF operational run is far less dramatic (though it does offer at
T+240 a tantalising hint that a northerly might be about to set in - I
think it's very much in a minority among its ensemble in that, though).
