This Evening and Tonight:

Remaining largely cloudy overnight as a band of rain and drizzle continues to affect much of the north and west. Drier in the east with a few clear spells. Windy in the northwest, but winds easing elsewhere by dawn. Minimum temperature 12 °C.

Friday:

Increasingly cloudy in the west with rain and drizzle pushing north-eastwards, turning heavy at times. Some brighter and drier intervals in the east. Winds continuing to ease. Feeling humid. Maximum temperature 20 °C.

Outlook for Saturday to Monday:

Remaining changeable with showers or longer spells of rain on Saturday. Turning cooler through Sunday as showery rain clears southeast, leaving sunny spells and showers on Monday.

It will be fairly settled to start the period but there will be spells or rain or showers in south and eastern areas, near to an area of low pressure. Elsewhere, some fog and frost patches are possible at times. 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. There may however be some thicker cloud and outbreaks of rain in the far northwest at times. Temperatures should gradually return closer to average in this period. Later there may be a return to a more changeable pattern but this is uncertain.

Confidence is very low in the weather regimes most likely to affect the UK during this period. 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.
