Dowlais (Merthyr Tydfil) weather

Headline:

Chilly tonight with fog and frost forming beneath clear skies.

This Evening and Tonight:

Cloud clears eastwards, with light winds and clear skies bringing a rather chilly night. Pockets of frost and patchy fog expected to form in rural parts. Turning breezier early Friday morning, with scattered showers arriving from the southwest. Minimum temperature 1 °C.

Thursday:

Windy, particularly along the coasts, with heavy rain spreading rapidly eastwards through the morning. Turning brighter later, and less windy, though with a few scattered showers still to come. Maximum temperature 8 °C.

Outlook for Friday to Sunday:

Storm Éowyn brings wet and very windy conditions on Friday morning. Winds easing into the afternoon and becoming more settled by Saturday. Increasingly windy on Sunday with rain arriving later.

This looks like being and unsettled period across much of the country, but especially for northern and western parts. During Monday, another deep area of low pressure looks likely to move across the UK from the Atlantic, bringing wet and windy conditions to most if not all parts. Further spells of wet and windy weather look like moving east from the Atlantic to affect the UK during the rest of the period too, with drier, brighter spells in between. There is the potential for further weather warnings or even a named storm at some point. Temperatures overall are likely to end up being around or slightly above average, though wind and rain will make it feel chilly, and brief cool spells with some overnight frost are likely between weather systems.

Generally mild at first, with periods of rain, showers and strong winds alternating with short-lived brighter and cooler interludes. These may become increasingly confined to northern parts during this period though, with pressure possibly building across southern areas in particular. This would result in longer drier and more-settled spells here, albeit with an increased chance of overnight fog and frost and temperatures falling a little correspondingly.
