UK long range weather forecast
An unsettled weather pattern is likely to dominate across the UK at the start of this period. Outbreaks of rain, heavy at times, and strong winds are expected as a deep area of low pressure crosses the UK later next week. This system will likely move away slowly to leave the following weekend showery and cooler in a northerly flow. Into the following week, conditions are expected to be changeable with showers or longer spells of rain across many parts of the UK. The cool northerly will likely persist for the first part of the week and wettest weather will probably be in parts of the north. Temperatures are expected to be close to or slightly below normal for the time of year.
Updated:
Changeable and unsettled with weather systems spreading from the west. These will bring spells of rain, heavy at times, and some strong winds, interspersed with drier, brighter, and less windy periods between systems. The heaviest rain will probably be across northern areas at first, migrating to western areas later. Temperatures are expected to be close to normal or slightly below.
