Forecast updated 28 Nov 2005
The Met Office continues to predict a two in three chance of a colder-than-average winter for much of Europe. If this holds true, parts of the UK — especially southern regions — are expected to have temperatures below normal.
There is also an indication for a drier-than-average winter over much of the UK.
The last eight winters have been relatively mild and perhaps have given the impression that these are 'normal'. The balance of probability is for a winter colder than those experienced since 1995/6.
The forecast is based on our prediction that the North Atlantic Oscillation (NAO) will be negative this winter.
Typically, when there is a negative NAO, we can expect much of the European region to experience a colder-than-average winter. Using a traffic-light analogy we consider that people should remain on amber alert for the prospect of a colder-than-average winter.
There will be regional variations across the UK this coming winter. For example, historically, when southern and central England experience a harsh winter, it is quite common for parts of Scotland and Northern Ireland to be less cold.
