Heavy rain
A locally dry start in the north and east, but rain advances in from the south to be widely heavy and persistent across the region for the rest of the day. Very wet underfoot, risk of flooding.
Extensive
Cloud will shroud the hills extensively for much of daylight hours, despite a rise in bases to upper slopes post front later in the day. To lowest slopes in heavy rain.

Fairly small, but risk becoming blustery, beware of deteriorating conditions, considerable buffeting and wind chill.
Heavy rain arrives, possible snow tops
Starting dry especially in east, but rain sweeps in from the southwest to become widely persistent, heaviest in areas near and west of the M74, later showery. May turn to sleet or snow highest tops.
Increasingly extensive
Some eastern hills may start free of low cloud, but patches on some slopes. Lowering cloud from the west becoming widely foggy across hills from mid or lower elevations upward.

Generally overcast, any early bright skies in east giving way to become dull. Visibility starting good in east, becoming poor in rain.

Areas of low pressure dominate into the weekend and early next week bringing unsettled conditions as a series of fronts circulate over Britain. Periods of heavy rain, with snow over higher mountains in Scotland as tops stay near or just below freezing point. Some freeze-thaw higher up, but mid-heights generally above freezing - very wet underfoot due to rain and snowmelt, beware flooding of streams and rivers. Most tops in England and Wales above freezing with terrain not frozen apart from local snow pockets. Generally windy, gales or severe gales at times over the tops - strongest speeds most sustained for England and Wales. Least windy in northern Scotland.
