The general inference says 'A ridge of high pressure
over Scotland and northeast England is drifting slowly northeast. Mild
conditions in the South of the British Isles will spread slowly north
over England and Wales. A belt of intermittent snow will move slowly
north over England and Wales turning to rain in the South. Falls will
be mainly slight but moderate snow may occur locally in Wales and North
England. There will be fairly extensive fog in the south tonight. It
will continue cold in Scotland but thaw conditions will spread north
over the South and Midlands' At 0600-warm front approaching from the
south. Currently aligned W-E along western Channel from Scilly through
Channel Is into N.France. (At midnight this front lay W-E through N.Brittany).
Cloud ahead of the front as far as Southern England, S. Wales and N.
France. Wind E to F5 in this zone. Light snow at Portland and light
rain at Plymouth. Clearer skies over the rest of the British Isles and
generally light winds or calm. Lowest temperature 07°F (-13.9°C)
at Leeming and highest 41°F (5.0°C) at Scilly. Overnight minima-generally
below freezing with Acklington the coldest on 0°F (-17.8°C)
and Scilly the warmest on 38°F (3.3°C) Previous day's maxima-once
again generally above freezing although at Renfrew the maximum was only
32°C (0.0°C). The warmest place was Valentia on 45°F (7.2°C).
Precipitation-dry in most areas except for the far south-west (Scilly
9mm) and north-east Scotland (Orkney 2mm, Rattray 2mm) Sunshine-prolonged
sunshine in most areas apart from south-west England. Acklington 10.1
hours Snow cover/extent-slowly wasting away. West Raynham and Waddington
are 6", Cranfield only 2" (a figure to be remembered for comparative
purposes in the near future!), Finningley 8", Acklington 5"
and Leeming 4". Greater depths (>6")in eastern Scotland
with Aberdeen and Lerwick on 12" The outlook suggests-slow thaw
and fog spreading north over Scotland with snow at first. Occasional
rain in the south with some bright periods in eastern districts.Mild
in the South, becoming milder in the North.
