Planning Outlook

High pressure is expected to influence our weather patterns beyond the middle of April. Often dry. Temperatures near freezing point on higher summits, tending to rise most afternoons. Lying snow on higher terrain will thaw only slowly. Some further overnight frosts. Next week may become milder with time. Sun and variable cloud; most mountains often clear. Mostly light winds, but southerlies strengthen this weekend. A frontal system coming in from the west by Sunday-Monday is likely to bring low cloud and some rain for a time, mainly in the west.
