Blaenavon (Torfaen) weather

Headline:

Drizzle in places overnight but turning brighter on Wednesday.

This Evening and Tonight:

Staying mostly cloudy overnight with the odd spot of light rain and drizzle in places. Misty in coastal areas with fog patches, mainly over higher ground. Occasional clearer intervals in the east. Generally frost-free. Minimum temperature 4 °C.

Wednesday:

Many areas starting murky with mist and fog possible and drizzle in places. Brightening up through the day with some sunshine developing for most. Light winds and feeling milder. Maximum temperature 8 °C.

Outlook for Thursday to Saturday:

Largely dry through this period albeit often cloudy. Some sunshine is possible at times with patchy frost and fog forming during overnight cloud breaks. Turning somewhat colder by the weekend.

This period is expected to see a transition, possibly lasting over several days, between the settled, dry, and often dull conditions expected over the next few days, to something more unsettled. Sunday itself is likely to be rather cloudy and cool, with outbreaks of rain in the west drifting slowly eastwards. The start of the following week will most likely see more settled conditions with light winds becoming re-established, with a chance of rain in both the far north and the far south, and a smaller chance that the rain could become more widespread. Later in the week, periods of much wetter and windier weather will most likely become more prevalent, from northwest to southeast, alternatively there is a very small chance of colder, drier, but perhaps wintry, easterly winds.

A dominant flow from the Atlantic looks likely through this period, resulting in an unsettled, milder and windier than average period. This is likely to result in areas of rain and periods of stronger winds affecting most if not all parts of the UK at times, though with the wettest and windiest weather probably occurring towards the north and west. However, the potential for brief colder spells with associated frost, ice and snow remains, following any deep lows crossing the region.
