Planning Outlook
After a lull on Sunday, areas of low pressure then circulating to the west and north will dominate the weather pattern into next week, bringing generally unsettled weather. Southwesterly air and briefly milder into Monday, with rain for most places at times, but prolonged heavier rain for England and Wales. Then typically cooler with showery conditions - higher mountains near or just below freezing point likely for the remainder of the week - some snow on tops, occasional hail. Wind speed likely to vary, some squally gusty spells, but also some lulls possible during the week ahead.
