Planning Outlook

An unsettled weekend ahead as low pressure brings heavy rain to England and southern Scotland on Saturday with strong winds. Conditions increasingly wet underfoot with streams in spate - some flooding is likely. A northerly wind in Scotland begins to draw unseasonably cold air into the Highlands, bringing freezing levels down to high terrain. Cold air flows into into England and Wales through Sunday on a strong wind - wind chills in direct exposure may reach as low as -10 to -15C. Some showers into northern Scotland on Monday will fade for a substantially dry week ahead with good sunny breaks for many. Temperatures staying cool but slowing rising day-by-day.
