Although I expected it to be windy I did not expect to see the lamp
posts swaying and hear the telegraph wires humming. Strogest wind of
the winter for this area anyway. Is there some wave effect going on
here?

It is almost certainly a lee wave effect by the Pennines. There was quite
a marked increase of wind speed with height near you (up to a mean of 55
knots at around 3000 feet) and a slightly unstable layer just above
mountain top height - above the low level inversion. The surface 15kn
westerly veered quite rapidly to a very strong NW with height.

Here is the 12z Nottingham ascent:

Hi Simon,

There's a marked inversion around 1100m on both the 12z RAF Waddington
and Nottingham ascents, hence strong winds to the lee of high ground. These
should decline throughout the night as pressure falls from the E and the
flow
veers.

Also of note today are some serious rainfall amounts falling in NW Scotland.
I look forward to Colin's report this evening, I imagine two to three inches
isn't
out of the question.

HTH Joe

A thoroughly foul day here.
Mild, but not mild enough to be interesting and windy enough to
be unpleasant but not strong enough to be interesting.
Oh yes and rain, but not heavy enough to be interesting..........

Yuk!
