After Graham's recent post I'm starting to feel a bit uneasy now, despite

my
being in shelter. Wind is picking up gradually and pressure is falling

rapidly.
Recent gust 48 mph at 10m agl with mean speed 20 mph. I don't like that

gust
factor of 2.4. Sleepless night ahead I feel.

Will, the 12Z NAE had gradient winds of 60-70KT ahead of the cold
front/occlusion and 80KT or so at first tonight. Line convection was also
evident with a non-zero risk of tornadic activity (your diagnostics have
already signalled low PROBs in the far west). Also of note were 50KT 10m
winds in the southern Irish Sea/western English Channel tonight and then
later tomorrow in the northern Irish Sea. As per
http://www.weather.org.uk/charts/UKCpf024.gif
Potent stuff with the key uncertainty being what percentage of the gradient
winds will be realised at the surface, particulalry inland.

Jon.
