Planning Outlook
A typical autumnal pattern in the week ahead: periods rain and strong wind, gales over tops at times, particularly in Scotland. Temperatures generally mild, some warmer windows in England and Wales, as well as cooler windows, chilly at times in Scotland, a little sleet possible on highest tops and feeling cold during strong winds. Best chance of near-term settled windows on Friday and Sunday: mornings start cool with scattered low cloud, lifting and breaking up, clearest on eastern hill groups. Weather remains mixed into next week with more swathes of rain and strong wind. A tendency towards high pressure building southwest of the country will bring more bright, drier days to England and Wales. Staying unsettled longer in Scotland. Indications of more extensive windows of settled weather in the later month.
