I know they said it was going to be slow moving but the cold front
has barely budged in the past couple of hours. I was expecting
rain by now, but it looks to still be several hours away.

Seems to be moving quite steadily according to the radar
(http://www.raintoday.co.uk/), say about 20mph at your latitude?

It's moving through Southern Ireland for sure, but the rain just
doesn't seem to be getting appreciably nearer to me.
The patch of rain over Cumbria certainly doesn't seem to have shifted
for several hours.

It looks like the main problem for you is the rain shadow area caused by
the Welsh mountains. Also, there could be a hint of a wave near the IOM
which has slowed things a little.

The Welsh mountain rain shadow usually affects Cheshire, the Liverpool
Bay area and southern parts of Gtr Manchester. It is unusual for it to
affect my area.
Cold front waves are, of course, a forecasters nightmare

It's been quite bright here for the last hour or so, sun breaking through
the clouds from time to time.
