Christmas 2012: Green for most called

Christmas weather forecast introduction
Welcome to our dedicated Christmas 2012 weather forecast page. This will update regularly (usually each Saturday) during the run up to Christmas from September 1st and will take into account the weather patterns which develop during the autumn. Please remember that our Xmas forecast is intended to be for fun, as trying to forecast a single day even one week ahead is fraught with difficulty. The forecast is based on what we expect the general synoptic conditions to be like during the late December period.

Forecast - Update 18
Update 17 called a Green Christmas 2012 for most of the country, and that remains the case with update 18. However, it is worth highlighting that showers could develop in places, and over higher ground in the north these could fall as sleet or snow at times, and there remains a chance of showers in northern regions turning wintry for a time down to lower levels. Once a call is made it means the chance of significantly changing the forecast becomes very low. The period between Christmas and the New Year looks changeable, with a risk of colder air across the country at times, so that's remains something to keep a look out for. Happy Christmas from TWO!

Probabilities of snow falling on Christmas Day
North of Yorkshire / Lancashire: 15%
South of Yorkshire / Lancashire: 8%
