Snowdon walk

Cold with sunny spells and scattered showers.

Today:

Frost and ice at first, especially in the east. Otherwise a fine and cold day for many with sunny spells and scattered showers, these heavy in places, but generally becoming confined to West Wales. Lighter winds than on Tuesday. Maximum Temperature 6C.

Tonight:

Cloud will thicken through the evening and overnight bringing outbreaks of rain, and some hill snow. As temperatures fall away frost and ice will form in places. Minimum Temperature -1C.

Thursday:

Some brightness in the east, otherwise a largely cloudy day with outbreaks of rain and drizzle slowly spreading in from the west. Becoming less cold in the far west later. Maximum Temperature 8C.

Outlook for Friday to Sunday:

Cloudy, damp and breezy on Friday, but slightly milder. Wet and windy weather on Saturday, clearing southwards to leave a cold and windy day on Sunday with sunshine and showers.

Day 6 to 15

Sunday will be cold with a mixture of sunny spells and scattered showers. The showers will arrive on a strong northerly wind, which will ease as the day progresses, and bring some snowfall over exposed northern hills. The snow may reach lower levels later in the day, especially across the northern half of the UK. Thereafter, the final few days of January and early February are likely to remain rather unsettled with brisk winds, outbreaks of rain and hill snow, as well as some showery interludes in between. It will remain cold for most with widespread overnight frosts as well as the risk of ice. Snow remains a possibility to lower levels, particularly in the north.

Day 16 to 30

The weather will continue to be mixed through early February with a continuation of the generally cold conditions. This will bring spells of rain and hill snow, interspersed by showery interludes, with a continued risk of snow to lower levels, especially in the north. As we head through February there is an increased chance of seeing very cold conditions developing with a greater probability of northerly or easterly winds. This will bring an increased risk of snow to all areas and more widespread frosts. In this scenario the driest conditions will be across the northwest, whilst the south could see wetter and occasionally milder spells, and these will bring a risk of some significant snow, but only if very cold air becomes established across much of the UK.
