Ystrad Mynach (Caerphilly) weather

Headline:

Cloud and rain this evening but turning brighter tomorrow.

This Evening and Tonight:

Cloud and light rain persisting at first this evening with rain gradually clearing to the north. Remaining cloudy overnight, which may be low enough to create some hill fog, with the potential for the odd spot of drizzle. Staying mild. Minimum temperature 12 °C.

Thursday:

A drier day ahead although still generally cloudy with the best of the brightness to the east. A brisk westerly wind, feeling warm and humid, particularly in any sunny breaks. Maximum temperature 23 °C.

Outlook for Friday to Sunday:

Wet and cloudy at first on Friday, with rain clearing southwards and brighter weather following. Saturday looks settled, before a bright, breezy and potentially warm Sunday.

Overall, a fairly unsettled period is likely, with many places seeing showers or longer spells of rain at times, interspersed by drier periods. Rain will likely be most frequent across northern and western areas, while the south and east are more likely to see longer drier interludes. There is also the potential for some strong and gusty winds, particularly in the northwest. Temperatures are likely to be near average, although brief warm or very warm spells are possible, especially in the south.

Confidence is low from mid-September onwards, however a gradual transition towards slightly more settled conditions for the second half of the month is currently signalled. The distribution of rainfall is uncertain at this range, but drier conditions compared to earlier in the month are likely for most, with any wetter spells generally more likely across the northwest. Temperatures are likely to be around average overall, although some warm spells are possible, particularly in the south.
