"A cool, bright day for Saturday," says the national forecaster. "Rather cloudy overall, but some hazy sunshine breaking through at times. few showers over parts of north Ulster, but dry elsewhere. Winds light or moderate westerly or variable and afternoon highs of 7 to 9 C." Not the worst, but it will get chilly. "Cold and mainly dry on Saturday night with a widespread sharp to severe frost away from Northern and Northwestern coastal areas, and patchy mist or fog forming in light winds. Overnight lows will range from 0 to 3 degrees Celsius." "Sunday will be rather cool, dry and bright in most places, with frost, mist and fog clearing during the morning. Cloudier, though in Northern counties with showery outbreaks of rain developing. Highs of 8 to 10 degrees Celsius with moderate West to Northwest breezes, fresher along the North coast." "Some frost in southern counties on Sunday night with temperatures falling close to freezing, but cloudier skies further north should prevent significant frost, but some patchy mist and fog may form." "A cloudy start in many areas with some showers in parts of the north and northeast in the morning. Mostly dry in the afternoon with cloud breaking and some sunny spells developing, best in southern areas. Highs of 10 or 11 degrees Celsius in light variable winds. Frost overnight." "Mostly dry settled weather looks likely for the rest of the week with light winds and variable cloud, daytime highs of 11 to 13 degrees Celsius, some frost by night when skies are clear. Some mist and fog patches overnight and in the early mornings also."
