Outlook for the UK over the next 6-30 days

UK Outlook for Monday 3 Oct 2016 to Wednesday 12 Oct 2016:

A dry and bright start to the week in the east and south, however windy and cloudy across northern and western parts with outbreaks of rain, perhaps turning heavy and persistent. This rain is likely to make slow, erratic progress eastwards during Tuesday. Through the remainder of the period, a continuation of the changeable conditions are likely with stronger winds and showers or longer spells of rain, interspersed with drier, brighter periods. The heaviest and most persistent rain along with the stronger winds, gales at times, are likely to occur in the west and northwest, whereas eastern and southeastern parts should see more prolonged drier and brighter spells, though even here some rain is possible at times. Temperatures generally above normal and warm at times in the east and southeast.

UK Outlook for Thursday 13 Oct 2016 to Thursday 27 Oct 2016:

There is currently low confidence for the forecast during the second half of October, however the most likely scenario is for a continuation of the more changeable conditions. The north and northwest are likely to see the most unsettled weather, with strong winds and showers or longer spells of rain, intermixed with some drier interludes. Further south and southeast there is a greater likelihood of drier, brighter weather with a low possibility of more prolonged settled spells here. Temperatures will vary through the period, but probably averaging out slightly above average for the time of year, though with an increasing risk of overnight frost in the more settled spells.
