My word, by next Saturday the GFS DT12Z is forecasting a 200+knot westerly
jet along circa 55N extending across the Atlantic and pointing straight at
UK. If this comes off, and it has been predicted by ECMWF too then we are in
for some very lively weather next weekend and beyond. Lot of very cold air
(sub 492 DAM) over Arctic Canada to become entrained too. Watch out Scotland
especially :-)

Will, does that mean some beefy depressions bombing over. I am going
caving and a slight choice of routes(and caves) but,however,decisions
are not made until we are up there. I have to wallow around in a
streamway so am expecting bloody cold water but the standard cave temp
does not alter. Thermals + furry suit + outer + balaclavas.

Mendips have a quick run off so hence the query about activity
