Many areas will see a mixture of sunshine and showers on Tuesday, though southeast England may see cloudier skies and outbreaks of rain. Thereafter, a changeable and at times unsettled outlook, with further low pressure areas tracking towards the UK, but with some uncertainty as to their paths at present. These systems could bring periods of heavy rain and strong winds to parts of the country. The wettest and windiest weather is more likely farther north and west. The best chance of drier conditions is across the east and southeast of England and will be closer to high pressure which is more likely to reside over continental Europe. Temperatures are likely to be generally above average, especially in the south.

Through early to mid October, generally blocked weather patterns are more likely than average, however there is significant uncertainty around the detail and resultant conditions over the UK. A typical mix of autumnal conditions may occur at times, although drier than average conditions are slightly more likely than wetter than average conditions over this period as a whole. Above average temperatures also continue to be more likely than below average temperatures, although cool nights, along with patchy mist and fog are probable during settled spells.
