Varied banks upper terrain

Variable ribbons of cloud above the middle slopes in the morning, most extensive towards coastal Cambrians. Summits may be between/above cloud layer. A lifting trend and much cloud breaking, though some thin banks cling to upper west slopes.

Chance of cloud free summits?

60%

Sunshine and air clarity?

Regular bursts of sunshine, more extensive later, but weakened by high cloud. Very good visibility.

Planning Outlook

Westerlies prevail across northern Britain. Rain, drizzle and low cloud over western hills from Lake District northward through the weekend. Temperatures near average, but feeling cool in exposure to wind on tops, which could regularly be quite strong and gusty. Generally drier northeast areas with higher cloud bases but patchy rain and drizzle reach here too. Higher pressure south maintains drier conditions in Wales and the south Pennines but cloud and some drizzle will affect high western slopes from time to time. A drier and warmer window looks probable from middle next week as high pressure builds. Very warm temperatures for England and Wales, spells of sunshine more widely. Some showers and patchy rain are likely to continue through late week and next weekend, though detail is uncertain.
