General Inference at 06GMT 'A depression over south
Denmark is moving steadily east and a ridge of high pressure will develop
over the British Isles ahead of a further depression advancing from
the Atlantic. Today weather will be cloudy generally with occasional
snow, mainly light and more especially in eastern districts. In the
extreme south-west there will be occasional rain or drizzle and there
is a chance of local freezing rain in the southern districts of England.
Some bright periods will occur in the north-west and tonight good clearances
of cloud will occur in western and central districts. Fair conditions
apart from scattered snow showers near the coast will spread to eastern
areas in the morning but further rain is expected to reach the extreme
south-west late in the morning. It will be very cold generally and hard
frost will occur in western and central places tonight, also slight
to keen frost in the east.' At Midnight-an elongated area of low pressure
is shown from southern Ireland to the Netherlands. This is the boundary
between mild air (mid 40'sF (7°C) to the south and air close to
freezing to the north). Snow is still falling over the north of England
and in southern Scotland. St. Abb's Head continues to report 'blowing
snow'. By 06GMT the depression has moved away eastwards and a cold front
is shown from north Devon to north Kent. By 12GMT the colder air has
reached all but south Cornwall and by 18GMT it is clear of the mainland.
