Planning Outlook
Variable temperature in the near term: warm on Wednesday for England & Wales at least, becoming cooler over western Scotland as a cold front sweeps eastward; more widely cooler Thursday with freezing temperatures on high terrain and snow showers; milder by Friday with some sun in England and Wales, settling on near-average temperatures over the weekend. A changeable mix of weather during this period with some rain and showers with snow or hail on the hills, and often windy late week into the weekend in Scotland. More settled England and Wales but a few windy, wet spells will affect these areas too. Into the following week, first indications of high pressure building, winds shifted easterly brining some rain to eastern areas but often sunny with lighter wind and near-average temperatures.
