Areas of mist and fog will form too. Lowest temperatures of 7 to 11 degrees with light variable breezes becoming light northerly in the north and west towards dawn.
Thursday: A bit of a contrast in conditions across the country on Thursday with a cold front acting as the dividing line between cooler conditions to the north and warmer conditions to the south. In Connacht and Ulster, Thursday will start out mostly cloudy with patchy rain and drizzle, but clearer, sunnier conditions will spread from the northwest for the afternoon. It'll feel much cooler with highest temperatures 12 to 16 degrees in light to moderate northerly winds. In Leinster and Munster however, Thursday will be mostly sunny to begin. Cloud will build for the afternoon, with a few showers breaking out, some of these possibly heavy and thundery. Highest temperatures will range 17 to 21 degrees with light variable winds becoming light to moderate northerly later. A mix of cloud and clear spells for Thursday night with showers persisting in southern coastal counties. Lowest temperatures of 4 to 11 degrees, coldest under long clear breaks in the north all in light to moderate northerly breezes.
Friday: Friday will be cooler and cloudier day overall with a few light showers in the mix but some bright or sunny breaks at times too. Highest temperatures of 12 to 16 degrees in a light to moderate northerly breeze. Dry and mostly clear on Friday night with a few mist and fog patches forming. Cloud will build in the north and northwest overnight. Lowest temperatures of 4 to 8 degrees in light northerly or variable breezes.
Saturday: Dry and bright to begin on Saturday with sunny spells, but cloudier conditions in the north and northwest will gradually spread southwards over the country through the morning and afternoon with a few spots of light rain or drizzle across the northern half of the country. It'll stay dry further south with the best of the sunshine here, although it does look like it will brighten up in most places during the evening. Highest temperatures 13 to 17 degrees in light to moderate northeasterly breezes.
Rest of the Bank Holiday weekend: High pressure will remain the dominant feature bringing generally dry and settled conditions with variable cloud amounts and sunshine. Temperatures look set to remain close to or slightly above the average for early May.
