Planning Outlook

A relatively quiet start to the week, but expect local showers or patchy rain. Lowering pressure Wednesday into Thursday then leads to an unsettled end to the week. Widespread rain and heavy showers, some thundery downpours. The most sustained rain likely focused on England & Wales. Windier too, the strongest winds expected across southern Britain, where gales are possible at times Thursday-Friday. A little warmer through midweek, but no imminent return to hot weather. Likely staying generally unsettled through the weekend as low pressure continues to influence Britain.
