Now thats interesting. Im not sure if you are on about the same bit but look at this sat here http://www.meteox.nl/h.aspx?r=&jaar=-3&soort=satradar
And see the lighter (whiter) cloud in the north East of the sea, North East running S.W. Was that the bit you were on about? Looks interesting...
Edit: Actually looks like it is more likely to hit central southern areas, that must be the feature they have been mentioning as possible light snow overnight in central areas.
