Planning Outlook

Low pressure to the south will develop and drift across Britain into the second half of this week bringing increasingly wet conditions widely. Areas of rain will drift northward during Wednesday, possibly thundery showers forming over England & Wales. Heavy and thundery rain likely affects England, Wales & southern Scotland on Thursday-Friday, potentially prolonged heavy falls bringing a risk of flooding locally. Northwest Scotland likely driest. The eastern Highlands often covered in low cloud. Strong gusty easterly winds prevail for a few days through midweek. Into the weekend it remains unsettled with areas of rain and heavy showers, plus cooler northwesterly winds developing.
