Summary valid for Sunday 20/11/05 to Saturday 26/11/05
TOI (time of issue) Thursday 17/11/05 1730 UK local time
This summary is based on a quick appraisal of the GFS, JMA, ECMWF, UKMO, FAX,
and ENS (NCEP ensemble) labelled charts available from the superb

High confidence for a lot of dry weather next week. Temperatures around normal
but with cold and frosty nights and an increasing risk of fog and locally
freezing conditions.
On Sunday high pressure will be centred over England giving a fine and sunny day
to most places after a frosty start. Winds generally light but possibly a
moderate easterly on the south coast where there may be a light shower.
High pressure should persist over the UK until Wednesday giving light winds and
sunshine in places with frost at night. However, stagnation of the air mass is
likely to lead to an increasing risk of fog from Sunday night onwards. Where fog
does form it could be very dense and freezing and a few places may stay in fog
and below freezing all day. Towns and cities though should clear and here
temperatures will be close to normal.
After Wednesday the high pressure is expected to retreat slowly northwestwards.
This will gradually introduce a freshening north or northwest wind to eastern
areas clearing any foggy air. Mainly dry, but late on Friday an increasing
chance of some rain getting into Scotland. Temperatures around normal but frost
and fog still at night.
Over the weekend the high will be well to the west and it looks like rain
followed by snow will push down from the north. Scotland, east and SE England
are most likely to see precipitation with mainly rain at low levels with sleet
and snow over high ground. However, some snow is likely at low levels later in
the north. Western parts of Engalnd and Wales should hold on to dry weather for
longer. Temperatures around normal at first, but turning colder with a fresh to
strong north or even northeast wind setting in in northern and eastern areas.
Winds lighter further west where some frost is possible at night.
Outlook for the following week. Staying cold with spells of rain, hill snow and
sunny spells in a north or northwest polar airstream. Possibility (25%) of
widespread sleet and snow pushing south to all areas. Heavy snowfalls possible
over high ground, especially in Scotland and northeast England, with temporary
blizzards. Confidence moderate for continuing cold conditions but low for
widespread wintry weather.
Finally, Haytor meteorological office will issue its first sledging forecast for
Dartmoor next week.
