Nuisance gusts in the early hours will ease, most small effects much of the day.

Largely dry start, rain sets in, risk thunder
A few spots of rain from the south early, many hill starting dry, but bursts of rain increasingly arriving from the south, setting in with time though afternoon with an increasing risk of heavy, thundery bursts.
Cloud on the hills?
Fairly extensive
Most slopes shrouded just at dawn, lifting towards high terrain for a time in the west; eastern hills unlikely clearing above 600-700m. Returning extensively to middle slopes as rain arrives, patches increasingly forming lower.
Chance of cloud free summits?
30%
Sunshine and air clarity?

Planning Outlook
Low pressure to the south will develop and drift across Britain into the second half of this week bringing increasingly wet, warm, and humid 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.
