Windy. Low cloud and patches of rain will clear southward across Wales. Otherwise, a drop in freezing level will bring snow showers to Scotland (mainly west and north), and bursts of sun. Although a rise in cloud base, most western mountains will remain shrouded in cloud.
Risk of the odd shower; cloud extensive on the hills, especially morning.
Northwesterly 25 to 35mph, risk 40mph temporarily after dawn.
Be prepared for very gusty conditions with considerable wind chill and buffeting.
Early patchy rain, then extensively dry.
A little rain late in night will be clearing from north at or soon after dawn. Otherwise, isolated if any brief showers (giving sleet highest tops).
Extensive after dawn. Will improve but not clear highest tops.
Extensive fog from dawn, bases around 300-600m, highest mid Wales. However, will gradually improve during morning from north as cloud base rises to fluctuate between 550m and 800m, perhaps clearing higher tops in east Wales.
10% rising to 30%
Patches of sun, mainly east Wales, developing by midday. Fairly murky conditions at first, but visibility becoming very good by midday.
3C, slowly dropping toward 1C
Falling close to highest tops later in day.

Gusty westerly winds increasing post dawn to 30mph.

Mostly dry
Dry morning but increasing chance of rain on some summits, mainly Snowdon range, in the afternoon. It will remain dry further east.
Extensive near west coast
Extensive cloud from lower slopes upwards on coastal mountains exposed in Snowdonia. Cloud base will rise progressively inland; the Berwyn Hills are likely to be cloud free.

Low confidence of timing of frontal system. Upland gales, westerly 30-50mph. Perhaps easing later.
Difficult and serious walking conditions where exposed to wind. Gusts may throw you off balance.
Showery in the west
Pockets of drizzle and rain will persist for most of the day before a band of rain arrives later on. Timing uncertain.
Low cloud in west
Cloud down to lower slopes, especially in western mountains. Cloud base will be higher inland and then lower as the front arrives.
40%
Cloudy or dull; mostly good visibility east Wales, but misty for periods west.
5C dropping to 2C
Above summits
Westerly winds, sometimes exceeding gale force at least in Scotland will continue until into next month. There will be frequent rainfall on western mountains; copious on the W & NW Highlands, where as temperatures oscillate, there will be both rain and snow - over time, the snow accumulation on the Munros. Further south, only occasionally will freezing levels be low, with most precipitation as rain. There remains uncertainty later Sunday (30th) when a small low may bring significant snow to the Scottish Highlands.
