12Z GFS Weds 13th is a step in the cold direction. i.e. high further to west
with good warm advection on western side helping to build it over the UK. More
changes to come no doubt, but a trend may be appearing? We shall see.
Still a critical few days ahead for snow lovers.

Ooom oom om in ya, ooom oom om in ya, ooom oom om in ya, .... :-)

Well the pattern change I at Haytor Meteorological Office hinted at last week
in
the regular weekly forecast looks like happening! :-O

Over the weekend, pressure looks like building over the UK and lasting well
into
the following week. This will introduce temperatures around normal with frost
and possibly fog at night, and, more importantly, some dry weather. Although
northern areas won't be completely dry. No sign of any cold weather as the
pattern is still slightly progressive which means the high could subsequently
topple away to our east. But ... as with any change it won't take much for the
upper atmosphere to develop the high to our west (as some runs are hinting)
thus
introducing a colder northerly and an interesting blocked pattern. The next
few
days will be critical for the outcome. But at least we will, one way or the
other get rid of this mild and wet SW'ly.

As a postscript, if the high does topple away east later next week then you
can
forget any cold weather until at least January and Christmas could well end up
exceptionally mild but wet in places. Also the Alps can forget about snow too,
as can most of Europe. So this week's developments are vital. Anyone know a
good
snow dance? :-)
