Just read this on the Metcheck website, fingers crossed lads 
The forecast issued by Benfield Hazard Research Centre for Winter 2005/6 indicates that a negative NAO this winter is three times more likely than an above average NAO. This information is based on ensemble forecasts using the well known link between June/July northern hemispheric snow cover.
The NAO, or North Atlantic Oscillation, is a loose-fitting index used by forecasters to gauge the activity of the Atlantic.
A positive NAO scenario is where pressure is high above the Azores and low above Iceland. This usually results in mild, South-westerly winds for much of the UK.
A negative NAO is the opposite. The result of this, is that blocking is a common theme and that colder outbreaks from the North or East are more frequent.
NCEP has backed this up, with the latest seasonal model also calling for a negative NAO this Winter.
