There once a topic about this but the original thread disappeared.

Below is a list of weather singularities that can effect Germany, Belgium and even France and Great Britain in the late spring:-

Ice Saints - Occurs between 12-14 May

Sheep Cold - Occurs between 4-18 June

Below is information on the singularities quoted from:-http://german.about.com/library/definition...ef05_0707.htm:-

"die Schafskälte a brief cold spell in early to mid-June or other summer months ("sheep's cold snap" - see note below)

Schafskälte bringt 20 Zentimeter Neuschnee in den Alpen. (Schlagzeile)

"Sheep's cold snap" leaves 20 cm of new snow in the Alps. (headline)

Gerade erst haben wir die Rekord-Eisheiligen hinter uns gelassen, da läßt bereits wieder eine Super-Schafskälte Europa bibbern. (Die Welt, 9. Juni 2005)

Barely do we have the record cold "ice saints" behind us, and already a super "sheep's cold snap" has Europe shivering once again. (Die Welt, 9 June 2005)

Note: A Schafskälte or Schafkälte is a statistically frequent European weather phenomenon. A true "sheep's cold spell" can result in a temperature drop of 5 to 10 degrees Celsius (9-18 Fahrenheit degrees) during the period between June 4 to June 18 (most often around June 11). The name comes from the risk to freshly shorn sheep from the unusually cold weather. It usually results from cool and damp northwesterly winds.

der Martinssommer period of nice weather in November"

Someone on this site said that the surprise Northerly outbreaks in May in Western Europe are caused by low pressure systems invading the North Pole. On the low's western side a Northerly wind can inject the displaced cold air from Greenland into the circulation of the westerlies which then invades Western Europe.
