UK long range weather forecast
Draft Friday is likely to be a windy day in most places with sunshine and showers. Gales are possible on western coasts and hills. The heaviest showers will probably in the west while some eastern places may avoid most of the showers. Next weekend is also likely to be rather windy with sunshine and heavy showers affecting much of the UK. It will probably stay changeable for the rest of the period with a mixture of some sunny days, and cloudier days with more persistent rainfall. It is likely to be windy at times, with the potential for gales, particularly in the west and southwest. Temperatures will vary around normal, but in any drier spells, they may be warmer than average.
Updated:
Confidence in the forecast remains low through this period. However, early October may bring spells of fine and settled weather, particularly in the south and east of the UK. These would bring bright days, but with the increasing risk of overnight mist, fog and some frost. Northern and western parts of the country may continue to see rain at times, and this might spread across the rest of the country as we go through October. Temperatures are likely to be close to the average, but with settled weather, some warmer days and cooler nights are likely.
