UK long range weather forecast

During the outlook period, the weather will turn more settled as high pressure builds in from the west. A few showers could still develop in places like the southeast during Saturday and Sunday afternoons, but for most it will be a dry weekend with periods of sunshine. It will feel warm with light winds, but it will feel cooler near the coast where onshore sea breezes develop. This fair weather is likely to continue for a few days into the following week, but thereafter the outlook becomes more uncertain. The south of the UK will probably be drier, although not ruling out scattered showers completely. Cooler and cloudier further northwest, where rain is more likely. Temperatures will probably be around normal or a little above average.

Updated:

Current indications are that the chances of high pressure or low pressure dominating are fairly balanced for this period. There is no strong signal for either dry or wet conditions being the more prominent feature of the weather. On balance, it is probable that a continuation of variable, slow moving weather patterns are likely through much of June, similar to that which has been experienced through May. However with potentially slow moving weather systems there is still a chance that longer-lived drier, or even wetter, spells are entirely possible too. Temperatures are most likely to be around or above normal.
