Planning Outlook
Varying conditions over the next couple of weeks as areas of high pressure build across the British Isles then slip eastwards. Some dry and bright days with light winds mixed with periods of strengthening southerly winds bringing occasional rain coming in from the west - Thursday this week sees rain move increasingly onto northwestern hills. Temperatures will vary, often lifting just above freezing to higher tops, but occasionally dropping back below freezing - chillier air briefly later this week. Some frosts into valleys during clear-sky nights. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, only patchy around highest tops in England and Wales with little impact on walking.
