Hey there snow anoracks or philistines here's a few interesting facts about Irish snow from our friends at Met Éireann.
The greatest depth of snow recorded in modern times was 45cm at Casement Aerodrome, during the winter of 1962/1963
The mean annual number of days with snow varies from 5 in the extreme southwest to 24 in the North Midlands.
A fall of at least 2cm is likely in most places about every two years while falls of at least 10cm occur every 7 to 18 years at midland locations, and in the north midlands about once every 6 to 7 years.
The origins of a White Christmas may originally have come from the 'Little Ice Age' that occurred during the period 1550-1850.
Snow fell on Christmas day on 12 days (1950, 1956, 1962, 1964, 1970, 1984, 1990, 1993, 1995, 1999, 2000, and 2004) since records began here in 1941.
In Ireland snow occurs most frequently in the months from December to March.
On 19th and 20th November, 1807 a disastrous blizzard swept the country and many people were killed. Two transport ships were wrecked on the east coast.
The early months of 1947 saw one of the most persistent cold spell of the century, with snowfalls affecting all parts of the country from late January until mid-March.
This winter was one of the most severe in recent times. The winter of 1963 was the oldest of the twentieth century. The second coldest was 1947, when more snow fell, but average temperatures were not as low.
2009/10 was the coldest winter since 1962/3, temperatures were around two degrees below average. There were between 20 and 30 days with snow in many places
The following winter 2010/11 was worse. Both Dublin Airport (-8.4°C) and Casement Aerodrome (- 9.1°C) had their lowest November temperatures on record on the 28th. The very cold weather continued into early December night-time temperature hit -16°C at Mount Juliet on December 3rd.
It became extremely cold again from December 16th with significant snow accumulations and record low December temperatures. Casement Aerodrome recorded a snow depth of 27cm.
