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 :-)

12Z ECMWF looks just as fearsome with storms and deep cold polar maritime
air set to sweep into Britain next Sunday (18th). Very strong flow at 500
hPa implying a powerful jet aloft. Flow finally sweeping away the remaining
vestiges of the block over Europe which looks like bravely hanging on for a
while next week.
