UK long range weather forecast

This period will see generally clear or sunny spells and showers for many throughout. Some areas in the southeast may remain dry, while the heaviest and most frequent showers persist in the west and northwest. Confidence remains low, with the possibility of high pressure building across the UK at some point through this period. However, frontal systems are likely to continue to bring periods of rain. We can expect generally breezy conditions throughout, with some brisker winds in the north and coastal gales possible, most likely to be earlier in this period. Temperatures will be close to normal throughout, but slightly below in northern areas, and trending slightly above in the south for a time. There is the possibility for some chilly nights, with potential mist or fog.

Updated:

Confidence remains low for this period. Sunny spells and showers are likely to persist across the UK, however there is the possibility for a deep low pressure system. This would likely bring periods of rain; however, some drier spells and potential mist and fog may be expected too, most likely at the beginning of the period. Temperatures likely to remain above normal throughout.
