Planning Outlook
A drop of freezing level onto higher mountains develops during Monday into Monday night; weakening fronts bringing some precipitation, but fading. Higher pressure expands across the British Isles into Tuesday and stays nearby with commonly drier conditions and periods of light winds during early March, though mixed with pushes of strengthening south-southwesterlies bringing some occasional rain in from the west. Often milder air during the next couple of weeks, possibly briefly colder again by the end of the coming week.
