Long range weather forecast
This long range forecast for the UK is updated once a month. Using the latest long range data from the NCEP and then run through custom software here at Netweather it is on the cutting edge of technology for long range weather forecasting. It is important to bear in mind that forecasting at this range is still in its infancy so can effectively be considered experimental.

Long Range Forecast - Goodbye Autumn & Hello Winter
Updated October 30th
So, we're up to the final month of Autumn, and just a matter of weeks away from the release of our full winter forecast. So far Autumn has been a mild affair, will that continue and will the trend continue into the winter period?
Although a fairly mixed month, a northwest-southeast split is likely to be a fairly frequent theme during November with northwestern regions often seeing more in the way of unsettled conditions, with locatons southeast likely to see more dry, settled spells. Temperatures are expected to be close to or above the norm for the time of year - so if this occurs it will mean all three autumn months have been warmer than average.
November Air Pressure
Heading into winter there is a lot of uncertainty currently, so confidence is low at this stage. Our forecasting model is suggesting that 'northern blocking' will come more into play at this point, but whether that will translate to cold air being pulled toward the UK too regularly is uncertain - currently temperatures are showing as close to, or a little below average. In terms of the rainfall, current expectations of for a close to average month in the south, drier further north.
December Air Pressure
Confidence falls ever further as we head into January, so not too much detail to show you at this point - as the pressure map shows below, that northern blocking is still in place..

The long range weather forecast displayed on this page is based on data from the Climate Forecast System from the NCEP (USA), run out to 9 months in advance and are updated once a month. The raw data is sent daily to Netweather, our systems then average and further process that data to produce the forecast you see below. The average figures you see on the forecast are not the standard 1971 to 2000 figures you may often see, instead they are rolling averages, currently from the period 1980-2008.
