'A depression over Biscay is moving east and filling
up. The somewhat milder air over much of England and Wales will be replaced
by colder east winds from the continent. There will be a return to day
and night frost over much of England and Wales with occasional snow
locally. There will be periods of sleet or snow in North England and
Scotland with temperatures at or a little above freezing on low ground.
It will be mild in extreme Southwest England, with local rain. Fog in
many parts of England will clear from the East.' At 0600 hours-Over
the last 24 hours the occluded front (of the previous 2 days) has moved
northwards to lie E-W across Ireland, Northern England (and the Netherlands)
by midnight. The front marks the boundary between very cold air to the
north and milder conditions to the south. (See Wijke's post today 'Re:
[WR] Sunday 9th February 1947. More snow in the South'). By 0600 hours
the front is showing signs of retreat, particularly in the east, where
it is now aligned NW-SE from N.Yorks to the E.Norfolk coast. Most areas
are cloudy, the only exception being Skagen, N.Denmark. The lowest temperature
on the chart is 14°F (-10.0°c) in NW Germany. Over the British
Isles the warmest conditions are to the south of the front and most
stations in England and Wales report temperatures just above freezing.
The lowest temperature is 30°F (-1.1°C) at Gorleston (just east
of the front) and West Freugh (5.5 miles SE of Stranraer) and the highest
is Scilly, St. Mary's on 46°F (7.8°C). Comparing the 00 hours
and 06 hours data shows that temperatures are already falling back to
freezing or below in Norfolk and Lincolnshire as the colder air moves
in from the E. Most stations in England and Wales report fog, with rain
in the SW. Snow is reported from South and East Scotland, the Western
Isles, Northern Ireland and NW Germany. Gorleston looks fairly unpleasant
with wind Force 4, temperature below freezing and continuous moderate
drizzle. Precipitation in the previous 24 hours-two wet areas evident.
The South-West and South Wales with up to 13mm, Aberporth and Plymouth
(rain) and eastern areas, 12mm at Finningley and 11mm at Tynemouth (snow).
Overnight temperatures-coldest 27°F (-2.8°C) at Leeming (N.Yorks)
and warmest 44°F (6.7°C) at Scilly St. Mary's Previous day's
maxima-coldest 30°F (-1.1°C) at Manchester and Finningley, warmest
45°F (7.2°C) at Predannack (S.Cornwall), Scilly and Guernsey.
Snow cover and depth-still widespread snow cover away from Cornwall
and south-western Ireland. 'Thawing snow' is the order of the day in
southern areas however.The greatest depths of snow (0900) are 14"
at Acklington, 10" at Little Rissington and 9" at Finningley.
Outlook-Wintry weather continuing, with snow in many districts.
