Glasfynydd Family Mountain Bike Route (Powys) weather

Headline:

Very wet today with flooding possible, especially in the southwest.

Today:

A widely very wet day with the rain often heavy and persistent. Flooding is likely in places, more especially in the south and west where disruption to travel is most likely. Winds falling light or calm for most. Staying mild. Maximum temperature 11 °C.

Tonight:

Staying very wet for many this evening with further flooding and travel disruption possible. Gradually becoming drier overnight with pockets of ground frost and fog possible later. A colder night. Minimum temperature 2 °C.

Tuesday:

Any mist and fog clearing, then a dry and increasingly bright day with some sunshine developing for many of us. Not as mild, albeit with light winds for all. Maximum temperature 10 °C.

Outlook for Wednesday to Friday:

Turning windier on Wednesday with coastal gales and further rain at times, this likely heavy and persistent by Thursday. Bright and breezy on Friday with sunshine and isolated showers. Mild.

Showers or longer spells of rain are likely to continue at first for many parts of the country, perhaps heavy at times, but gradually over the weekend the weather is expected to become more settled. Scotland and Northern Ireland are likely to see this change first, with spells of rain perhaps slower to clear further across the south. Into the following week, high pressure is expected to become more widely established. Winds will be light and clearer skies are likely, however this does not rule out the odd shower, especially around coasts. High pressure and settled weather will result in temperatures falling to closer to average, with overnight frosts and morning fog which could be slow to clear.

High pressure will probably remain influential across the UK during this period. This means an increasing likelihood of dry weather compared to the winter so far. Despite the greater signal for settled weather, showers or occasional bands of rain are still possible at times, especially later in the period towards January. These could be wintry in nature. Temperatures are expected to be close to normal for the time of year.
