Not knowing what to expect after seeing or hearing a weather forecast is
something I'm used to nowadays. Anyway, 7C sounds about right for
a "bitterly cold" day these days - i.e. temperatures about normal. The
long
track of northerly winds over warmer than usual water brings surface
temperatures up to normal by the time the air gets here.

Which I why I cannot understand how weather warnings for the SW have
consistently given a 60% chance of disruption on Scilly due to snow,
when the SST around the islands, which barely poke above sea level is
still close to 11C, and there own forecasts have shown minima in the
islands never lower than 6C.

I would give the chance of disruption on Scilly (due to snow) as
pretty close to 0. Rough sea commonly causes disruption to services
there, but that never qualifies for a warning.

It is a fundamental problem with the warning system in that the resolution
is too coarse. There could well be a significant chance of disruption over
the moors which then is applied to the whole of the SW.
