High pressure influences Britain through the next week to 10 days, maintaining quiet and fairly cool conditions, although a gradual rise of temperature is expected. Frost remains common, with a general rise of freezing level on the mountains into the afternoons. Existing lying snow on higher mountains will stay in place, thawing slightly during daytimes. Sun and variable cloud; most mountains often clear. Very little precipitation, apart from very isolated showers of snow or soft hail. Mostly light winds, but there may be some strengthening of wind around next weekend.
