1st - 8th A changeable, mainly dry period as
weak fronts crossed the region between low pressure to
the north and high pressure to the south. There were
sunny periods but it was rather cold at first with some
overnight frost and fog patches and some occasional
wintry showers in the north-east. From the 5th onwards
it was mild or very mild, however the 6th was windy with
some rain in the north.
9th - 13th Generally changeable with occasional rain
and mostly mild. A small intense low moved eastwards across
northern districts during the 9th bringing gales to many
areas and some snow to high ground in northern England.
With gusts over 60 knots in Norfolk a marked 'Fen Blow'
was experienced as the strong winds lifted the topsoil.
A gust of 67 knots was recorded at Mumbles Head in south
Wales. The 10th was also windy with more gales in western
and northern areas, while Boltshope Park (Durham) boasted
10 cm of snow that morning. As low pressure transferred
to Biscay during the 12/13th a quieter interlude developed.
Northern areas were sunny but with overnight frost, Shap
(Cumbria) falling to -6.5 °C early on the 13th. Rain affected
extreme southern areas from time to time.
14th - 20th
Unsettled with periods of rain heavy at times. An
anticyclone over Scandinavia fed chilly easterly winds
at first, but falling pressure in the south-west
approaches brought rain on the 14th and 15th, especially
to southern areas. Thundery showers affected the Norfolk
/ Suffolk coast later on the 15th. Low pressure centred
in mid North Atlantic brought mild southerly winds on
the 16th and 17th but rain heavy at times spread in
later, with thunder reported along the Channel coast.
The 18th was wet as a low moved from the Severn estuary
to the Wash, while rain with hill and coastal fog were
the uninvited guests to southern parts on the 19th and
20th.
21st - 31st Mainly dry, sunny
anticyclonic weather prevailed as pressure rose over the
region and drifted east. It was mostly very mild by day
but with some overnight fog and frost later. On the 28th
early morning fog caused multiple accidents on the M40.
The 29th and 30th saw temperatures reach 18 °C in the
London area, making it the capital's warmest March Good
Friday, although scattered showers affected places in
the Midlands, East Anglia and south-east England later.
As the high pressure lost ground Atlantic fronts brought
patchy rain and drizzle to many areas on the
31st.

| Diary of Highlights |
The weather in March was varied, with no
particular spell of weather lasting for a long time.
Mild weather predominated, with relatively little frost
and snow.
The month began with a cold and clear northerly
outbreak, but winds soon backed into the west, allowing
mild and cloudy weather to advance across the
country.
Strong westerly winds blew between the 4th and 6th,
with gusts reaching 64 knots at Muckle Holm on Shetland
on the 4th. Mild and humid air brought torrential rain
to the West Highlands on the 5th, with several gauges
recording over 80 mm.
Westerly winds continued for the next few days, but
it became colder, with snow extending to low levels
between the 9th and 10th. The precipitation took the
form of showers on the 9th, with more general snow for a
time early on the 10th. Gusts reached 69 knots at Barra
on the 11th.
An anticyclone that developed over Scotland gave the
first fine spell between the 12th and 14th. The clear
skies and light winds allowed the temperature at
Corgarff to drop to -7.3 °C on the 14th.
Southerly winds covered Scotland between the 15th and
19th as the high moved away to the east. After a period
of cloud with some rain, milder and brighter weather
arrived.
From the 19th to the 25th, a contrast in weather
across Scotland was brought about by a slow moving
front. The north-east was bright and rather cold, while
the south-west was cloudy with outbreaks of rain.
An anticyclone, which became slow moving over
Germany, gave the second fine spell over most of the
country from the 26th to 29th. In the north-west it was
rather cloudy, with south-westerly winds gusting to 61
knots at Stornoway on the 26th. For the bulk of Scotland
there was much sunshine, with frost at night and
pleasantly warm days. On the 28th the temperature at
Fyvie Castle rose to 18.5 °C.
As the high retreated, the last couple of days saw
the return of cloudy weather with a little
rain.
