'A complex depression over Atlantic with deepening
secondary south of Ireland moving NNE quickly. It will be mild and rather
cloudy over Wales, west Midlands and southern Ireland with a few bright
periods at first followed by mild conditions, but a further belt of
rain soon reaching west England and Wales will move across the country
giving rather prolonged rain in North England but clearing all eastern
districts by tomorrow with fair periods and scattered showers following.
In North Ireland and Scotland there will be periods of rain with local
sleet in North Scotland, milder conditions will reach all areas except
extreme North of Scotland. There will be much fog and poor visibility
over northern half of England, south and central Scotland' After several
attempts in the last couple of weeks it looks as if the milder air is
finally going to displace the cold air which has been over the British
Isles since the third week of January-but what a slow process. At Midnight-warm
front London to NW Scotland and further occlusion Dorset to N.Ireland
both moving NE. Small depression SW of Ireland moving quickly NE. Cloudy
everywhere with temperatures still close to or just below freezing from
E.Anglia/Midlands northwards. Rain in SW, sleet in central areas but
snow still falling in parts of NE England and Scotland. W.Freugh still
reporting blowing snow. At 06GMT-warm front now E.Essex to Skye and
occlusion W.London to Islay moving NE. Another warm front has appeared
lying Beachey Head to S.Cornwall moving N'wards. Milder conditions are
now a little further north. Rain in southern areas with sleet and snow
in north but now more scattered. At Midday-milder air now well north
with E.Anglia and Midlands now showing the higher temperatures. By 18GMT-
the temperature distribution show that colder air has slipped back southwards
over the northern half of Ireland with 'continuous moderate snow' at
Aldergrove and 'blowing snow' at Collinstown. Precipitation- (21h-21h)-10mm
to 15mm in many districts. Particularly wet in Ireland, 30mm at Collinstown
and 55mm at Roches Point. Overnight minima-Rattray coldest on 23°F
(-5.0°C) and S.Cornwall warmest on 45°F (7.2°C) Daytime
maxima- Croydon warmest on 57°F (13.9°C), which is significantly
warmer than the maximum of 35°F (1.7°C) on the previous day.
Lowest max was 36°F (2.2°C) at Acklington, Lerwick and Dalwhinnie.
Snow cover/depth-by 18GMT the only significant lying snow reported for
England and Wales was 5" at Waddington and 9" at Acklington.
Scottish stations still reporting lying snow with the deepest at Lerwick
(13") and N.Ireland reports snow lying. Wind-as the secondary depression
moved across England and Wales there was a widespread and severe gale.
At 18GMT Boscombe Down, Cranfield, Honiley, Fairwood, Pembroke and Aberporth
all reported F9 whilst Exeter reported W'y F10. (Mildenhall registered
98mph and Cardington (Beds) 93mph).
