UK long range weather forecast
A largely unsettled picture looking ahead through the forecast period, starting with showers and longer spells of rain on Thursday. Generally windy conditions coupled with spells of rain and showers will continue through the week and likely into the following week too, with those showers becoming heavy and blustery at times. The heaviest rain most likely in the north and northwest which may also see gales at times. Meanwhile there may still be brief interludes of drier and sunnier weather, most likely perhaps in the south and southwest. Temperatures will generally be rather cool, potentially cooler in more persistent rainfall, and overnight frost may be seen in prone parts of the north as and when calmer spells of weather allow.
Updated:
The early part of October is looking to be a cool and unsettled period at first. Overall, southern parts may see the most of dry and brighter spells whilst the wettest and windiest weather will be most likely across the north and northwest. Later in the month, conditions may generally begin to settle down and temperatures may nudge back towards average or slightly above average for the time of year, though with significant variation between warm and cool spells. Morning fog and patchy frost may also become more prevalent towards mid-month.
