Planning Outlook

Low pressure to the north of Scotland brings stronger wind and a greater risk of showery rain from Thursday. Cooler temperatures, high Munros staying below freezing for several days, the freezing level as low as 800-1000m. Showers affecting England and Wales, always a risk of heavier bursts afternoon, but timing and location of showers uncertain. Early varied cloud tends to lift to higher slopes, often above summits but some tops shrouded for longer. Into the weekend, low pressure south of the British Isles, facilitating a strong easterly wind with increasingly heavy rain and showers for Wales and southern Pennines. Pressure may remain higher in Scotland for a few days, but staying cold here with freezing levels perhaps to 700m. Indications of increasingly widespread unsettled weather into next week.
