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.

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.
