Met Éireann, the meteorological service for Ireland, predicts a significant drop in temperatures tonight, falling below freezing. Despite the cold, Ireland is expected to experience a sunny weekend with pleasant conditions today and tomorrow. However, this mild weather is short-lived, as rainy and windy conditions are anticipated to return next week. The forecast indicates a shift in the weather pattern, bringing a return to more typical autumnal weather. Residents are advised to prepare for the colder temperatures and potential disruptions next week. The return of unsettled conditions suggests a change from the current unseasonably bright days.
