Hay-on-Wye (Powys) weather

Headline:

Widely cloudy with hill fog, and a few wintry flurries.

Today:

Mainly dry but cool and rather cloudy. Some brighter spells developing in the far west, though still feeling rather chilly. Hill fog lingering across the Eryri mountains, with a few wintry flurries at times and light winds. Maximum temperature 7 °C.

Tonight:

Another cloudy night with a rural frost possible in the mountains, though most places remaining frost free. Mainly dry, though patchy light rain arriving in the southwest by morning. Minimum temperature 2 °C.

Thursday:

Widely cloudy with patchy light rain and drizzle at times, mainly over higher ground. Feeling chilly in a southeasterly wind, and becoming breezy through the evening. Maximum temperature 6 °C.

Outlook for Friday to Sunday:

High pressure continues to bring cool and rather cloudy conditions. An increasing risk of rain, perhaps hill snow, and feeling rather breezy. Some cold and frosty nights over the weekend.

South or southeasterly winds are likely at the start of this period, and will maintain below average temperatures and often cloudy conditions. There is a chance of even colder conditions developing temporarily, which would see more wintry showers, especially in northeastern areas. Meanwhile, frontal zones, bringing milder conditions and rain, will attempt to move in from the west or southwest. Early in this period these look likely to have limited influence over the UK (apart from the far SW which may already be milder by this point). If, or when, they push further northeastwards the chance of some snow increases. The transition between colder and milder conditions remains uncertain, but towards the end of this period, the milder, wetter conditions are likely to have spread across much of the country.

There is still a very small risk of colder conditions lingering for a time at the start of this period, but it is much more likely that a milder and unsettled theme will probably have become established, with weather systems moving close to or across the UK. This will mean bands of rain and perhaps periods of strong winds spreading in from the west, interspersed with some drier and brighter interludes, but likely bringing above average rainfall amounts overall, especially in the south and west. Temperatures are most likely to become close to or a little above average by early March.
