Additional weather information
Meteorologist's view
Heavy downpours bring a risk of waterproofs becoming drenched. Navigation may be tricky in low cloud and it will feel cool at times on higher slopes with a brisk wind and rain.
Weather
A largely cloudy start with some brighter spells and the odd spot of rain. In the afternoon low cloud and rain, heavy at times, will spread eastwards. Drier and brighter spells in the late afternoon and into the evening before heavy and perhaps thundery showers develop later. Strong winds on higher routes.
Chance of cloud-free hill tops
70% much of the morning, from late morning dropping to <10%. Best chance in east.
Low cloud and visibility
Occasional low cloud for much of the morning, base around 700m, but still a chance of cloud free tops, especially in the east. In the afternoon low cloud becomes more widespread with bases falling to lower slopes in heavier rain, the east seeing higher bases and more breaks. Visibility good outside of cloud in the morning, falling to poor in cloud and rain later.
Ground conditions
No recent ground conditions report available.
