Figure 1.

There was one brilliant day of warmth and sunshine in March over much of the country, the 5th, when the temperature topped 17°C in parts of south Wales and the London area. The visible satellite image for 1243 utc (courtesy of University of Dundee) shows the extent of the clear skies. There is, though, fog over parts of northeast England; this persisted all day along the Lincolnshire coast where Donna Nook had a maximum temperature of 2.9°C.

March was, of course, much more memorable for its unseasonable cold and snowstorms. The radar image for 1200 utc on the 11th (courtesy of meteox.co.uk) focuses on an event Channel Islanders are unlikely to forget for a long time. Snow showers are apparent over much of the British Isles, but a blizzard was affecting the extreme southeast of England and for many hours Guernsey reported a gale and heavy snow.

Figure 3.

The radar image for 1900 utc on 16 March (courtesy of meteox.co.uk) picks out significant convective activity (despite low temperatures) over much of southern Britain. Bands of heavy showers drifted northnortheast into England from late morning, and there was a mix of thunder, hail and snow amongst them. There were also areas of snow over Scotland, where the maximum temperature at Salsburgh, near Airdrie, was only 0.7°C.

Late March weather has rarely been more inclement in our islands than over the weekend of 23/24 March. Strong winds and heavy snow caused major drifts and chaotic conditions over a large central core of the country. However, the visible satellite image for 1250 utc on the 23rd (courtesy of University of Dundee) shows a clear southern edge to the cloud sheet: St Helier (Jersey) had a maximum temperature of 12.9°C and 9.8 hours of sunshine!
