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.

00Z Sunday GFS shows jet slamming into SW Ireland by 06Z Sunday with left
exit (strong development zone) over Irish Sea. Jet then sinks south and
weakens slowly.
Next week is going to be *very* interesting.
*Potentially* we could have:
Storms and inland gales causing widespread damage anywhere in UK
Widespread blizzards over Scotland.

Just a heads up, the detail will change :-)
