United Kingdom long range forecast
On Saturday, most parts of Scotland and Northern Ireland will see sunny spells and scattered rain. The central or southern areas of the UK are likely to see a band of rain, which may start to move northwards. Temperatures are fairly cool below and north of this; But it is warmer and more humid in the south, with some showers and thunderstorms possible here. Over Sunday and Monday, these warm and humid conditions with the potential for heavy rain and thunderstorms are likely to spread northwards to other areas of the UK, displacing more stable and drier conditions northwards. Further afield, conditions are likely to be variable, with periods of rain or showers for many, more frequent in the north and west. Temperatures are likely to be around or slightly above average.
September 26 – October 10
Confidence in the forecast for late September to early October is declining, with uncertainty increasing in part due to the remnants of tropical storms in the Atlantic. However, there is likely to be an increased incidence of high pressure around the UK than usual at this time of year, which could lead to stabilizing weather conditions. Temperatures are also likely to be above the overall seasonal average, with warmer than normal periods more likely late in the season.
