UK Outlook for Wednesday 15 Feb 2012 to Friday 24 Feb 2012:

Wintry showers are likely over some northern and eastern parts of the
UK on Wednesday, with outbreaks of rain and drizzle more likely
elsewhere. It will probably remain unsettled during the second half of
next week and northern parts of the UK will probably see periods of
rain, with snow possible on high ground, perhaps to low levels at
times in the north and east. The south and west will remain drier and
brighter, although with rain possible at times. Many areas should see
temperatures around normal for a time next week, but it is likely to
become colder than average by the following week. With the weather
likely to remain unsettled, showers or longer spells of rain are
likely across the UK, with further sleet and snow in places.

UK Outlook for Saturday 25 Feb 2012 to Saturday 10 Mar 2012:

The last few days of February and beginning of March are likely to see
changeable weather. Temperatures are probably going to be average or
below average for the time of year. Being late February/early March,
this suggests that overnight frosts are still likely, especially
during any quieter interludes. Showers and longer spells of rain are
possible with an ongoing risk of snow, mainly in the north and east.

Looking at the GFS medium range charts and reading between the lines of
the above forecast (especially the bit about precipitation to the north
and east) I think that it will not be the Russian High returning but
rather the Azores High having a little wander to the north, so giving us
the cold N or NW set up which Will has spoken of in another thread. The
850 hPa temperature charts certainly show the cold air coming from
somewhere near Spitzbergen or Greenland rather than somewhere near Moscow.

Aesthetically, this is much to be preferred as the cold easterlies off
the Continent have a habit of being hazy in depth whilst the N or NWlies
can be brilliantly clear which is nice for those who like the starry
skies. It would be nice to have a good view of the impending
conjunction (close approach) of Venus and Jupiter in the evening skies.

It would also be a relief for our Continental cousins, who have had more
Russian air than they know what to do with these last few weeks. They
need a break.
