Diffwys (Gwynedd) weather

Headline:

Cold tonight, then chilly and increasingly cloudy on Sunday.

This Evening and Tonight:

Breezy with the chance of a few showers at first this evening but becoming dry, clear and chilly overnight. Winds easing and turning cold with some frost developing in the countryside, especially away from coastal areas. Minimum temperature 1 °C.

Sunday:

A cold but fairly bright start with some hazy sunshine. Cloud generally thickening through the day but staying dry. Feeling chilly with temperatures struggling for the time of year. Maximum temperature 11 °C.

Outlook for Monday to Wednesday:

Rain on Sunday night, then turning brighter on Monday. Showers possible on Tuesday but mainly dry in the east. Rain at times on Wednesday, occasionally heavy. Much milder than recently.

Through the second half of next week conditions will be very unsettled with rain affecting most regions at times. The heaviest rain is likely to be in the west or southwest to begin with, but later in the week, the focus probably shifting to central and eastern areas. Following the rain, a drier and brighter interlude is probable, before conditions turn unsettled once again by next weekend. However, most of the rain, showers and strong winds are likely to be in the northwest with southeastern areas often dry and bright. Temperatures will be above average and probably feeling warm in the brighter spells. Later in October, there is a chance of more settled conditions developing, but with temperatures falling closer to average and some overnight frost and fog.

Potentially some wet and windy weather at first, especially in the northwest, but a trend towards more settled conditions is most favoured for late October as high pressure becomes increasingly dominant. This would bring the potential for frost and fog at night, and possibly large variations between daytime and overnight temperatures. Into early November, high pressure may become more centred to the northwest of the UK, resulting in a gradual trend towards more unsettled conditions, particularly across southern regions.
