A dip in temperatures overnight will bring a touch of frost to parts of Armagh and Fermanagh on Saturday morning and a mostly clear day is forecast.
There will be plenty of sunny intervals throughout Saturday but where clouds appear they may produce a few passing light wintry showers. Maximum temperature on Saturday is 11C.
Sunday should be similar to Saturday before a noticeable drop in temperatures on Monday and Tuesday.
A Met Office spokesman said the beginning of the week will be “much colder and windy with a few blustery snow and sleet showers”.
