UK long range weather forecast

A change to cloudier weather with outbreaks of rain, these most prevalent in the west of the UK, is expected to be well underway by the start of the forecast period. However, this may not last too long, as it continues to look increasingly likely that a drier, warmer, and settled spell will begin to develop later this coming weekend, and into the following week. There is a small chance that this could persist for much of the rest of the period, turning increasingly hot, however by mid-next week a large range of outcomes which also include a small chance of colder, more unsettled weather also become possible. Generally settled, and warmer than average conditions appear most likely.

Updated:

There is little sign for any one type of weather pattern to dominate during this period. As such, typical conditions for the UK are most probable with a mixture of weather types. All areas can expected to see some spells of drier, sunnier weather, but there will also be showers or longer spells of rain at times. Currently the only signals, weak as they are, hint that rain and showers will tend to be more biased towards the north and west, with any more prolonged drier interludes favouring the south. Temperatures are slightly more likely than normal to be above average, than below.
