Heath (Cardiff) weather

Headline:

Cloudy with outbreaks of rain. Breezy.

This Evening and Tonight:

Rain persisting throughout this evening and overnight, this turning heavy at times especially in the south over the hills and mountains. Windy for all, particularly along the coasts, and feeling humid. Minimum temperature 13 °C.

Thursday:

A cloudy, damp and mild start to Thursday. Cloud breaking in the east with some brighter spells, but drizzle persisting over the hills in the west. Staying windy and humid. Maximum temperature 20 °C.

Outlook for Friday to Sunday:

Remaining changeable with showers or longer spells of rain at times. Some brighter periods are also likely, mainly on Friday. Temperatures close to average but turning colder through Sunday. Breezy.

Into next week, a northwest-southeast split is most likely. The best of drier spells will be in the north and northwest where some fog and frost patches are possible, but there will be spells or rain or showers in south and eastern areas, near to an area of low pressure. It will also turn colder, as a northerly flow becomes established for a time. Later in the week, more widely drier and settled conditions could develop as high pressure becomes more influential, although probably still with some coastal showers. Temperatures should gradually return closer to average in this period. Later in the period there may be a return to a more changeable pattern but this is uncertain.

By the beginning of October, confidence is very low in the weather regimes most likely to affect the UK. On balance, there will likely be a transition from slow-moving weather patterns to a more changeable period at some stage although the timing on this is highly uncertain. High pressure probably close to the UK, which would offer some occasional periods of dry weather, will likely give way to a more unsettled period with some short lived dry interludes during this time. Temperatures will likely fluctuate either side of, but often close to, average.
