The forecast probabilities are calculated by combining results from statistical prediction methods, guidance from global seasonal models and assessment of climate warming trends.

Probability that winter temperatures will be above/below average.
In most parts of Europe above-normal winter temperatures are forecast to be more likely than below-normal temperatures. In northwest Europe and parts of the Mediterranean the odds for warmer-than-normal versus colder-than-normal are at least 60/40. Elsewhere, including parts of southern, central and north-eastern Europe, the odds for colder or warmer than normal are more evenly balanced.

Probability that winter precipitation will be above/below average.
The forecast methods currently give no clear evidence to favour one precipitation category over the other.
