I don't know what satellite pictures you were looking at, but the past
couple of days of Meteosat pictures show the outflow cloud from
hurricane Gordon being sheared further and further NE towards the UK.
The reason for Gordon declining to a "feeble ex-hurricane" - apart from
it encountering lower sea temperatures - was the increasing shear it
encountered as an upper trough caught up with it.
.... not sure if this link will work, but it takes you to the Meteosat
site where you can pull up WV imagery and animate same. Unfortunately
there is no ability to enhance the contrast (or colour-slice) so it's a
bit 'wishy-washy', but you can pick out the high-concentration WV (and
solid/liquid state water) being injected into the upper troposphere from
'Gordon' and then latterly being picked up and shed NE'wd ahead of the
major upper trough progressing towards the British Isles.
