Frost and fog to clear as sunny spells and showers forecast for Mayo

Any lingering frost or fog will clear on Friday morning, giving way to a day of sunny spells mixed with scattered showers, according to the latest forecast.

Some of the showers are expected to be heavy at times, with a risk of hail and isolated thunder.

Daytime temperatures will remain on the cool side, reaching highs of between 6 and 8 degrees, while light to moderate southeasterly winds are forecast.

Conditions will stay cool by day and cold by night across the country, with frost, ice and freezing fog a recurring feature.

While many areas are expected to remain dry and calm over the weekend, a slack area of low pressure will bring well-scattered showers and lingering fog in places.

More unsettled weather is expected later on Sunday and into Monday, when heavier and more organised bands of showers are set to move in from the Atlantic.

Scattered showers will continue into Friday night, but the main feature will be the development of widespread fog or freezing fog under near-calm conditions.

Overnight temperatures are forecast to fall to between -2 and +3 degrees, with the coldest conditions away from eastern coastal areas.
