Friday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Heavy snow and hail showers, isolated lightning
Showery precipitation, often heavy, may merge to become constant for periods. A mix of snow and hail often falling to lower slopes. Risk of very localised thunder and lightning.
Hazy, some fog banks

Fairly extensive, some breaks west
A cloud sheet likely to cover many hills most or all day from mid-elevations upward. Further west, the cloud base higher and some breaks likely, best toward the coast.
Chance of cloud free summits?
20%, to 40% furthest west.
Sunshine and air clarity?
Some glimpses of sun mainly toward Cardigan Bay. Otherwise overcast and dull, misty from low-mid slopes upward.

Planning Outlook
Often dry and chilly conditions into the weekend with a south to south-easterly airflow developing, gusty wind in places. General patterns into the second half of January favour a colder continental influence. The snow pack across the Scottish Highlands will be enhanced by further spells of snowfall where where fronts edge in from the west, whilst for England and Wales snow accumulating on the hills at times, perhaps in the form of showers from the east.
