Slieve Bearnagh (County Down) weather

Headline:

Mostly dry with sunny spells Friday.

This Evening and Tonight:

Cloud with outbreaks of patchy light rain will die out this evening. Then the rest of the night will be largely dry with some lengthy clear periods. Chance of cloud and rain fringing into eastern County Down at times. Minimum temperature 10 °C.

Friday:

It will be largely dry with some brightness. Chance of a little rain across County Down at times. Maximum temperature 17 °C.

Outlook for Saturday to Monday:

Cloudy on Saturday with rain likely across the east, becoming windy later. A colder day on Sunday with showers. Bright and largely dry with fewer 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.
