This week will see a notable drop in temperatures, with quite cold nights on the way later in the week, according to Met Éireann’s latest weather forecast.
Today (Monday, September 23) will be mostly cloudy with just limited sunny spells. It will be misty in parts to begin also. Residual patchy rain in the southeast may be slow to clear for a time during the morning.
A few scattered showers will occur also, mainly across the west and north. Highest temperatures will be 14° to 17° in a light to moderate north to northwest wind.
It will be overall dry tonight with clear spells, but some patches of mist, fog and drizzle. Some showery rain will feed into northern and northwestern fringes too. Lowest temperatures will be 6° to 10° in a light northwesterly breeze.
Tomorrow (Tuesday, September 24) will see well-scattered showers and some spells of hazy sunshine. Highest temperatures will be 12° to 16° in a light to moderate west to northwest breeze. In the evening, cloud will thicken from the southwest.
Tomorrow night, outbreaks of rain may affect southernmost parts of the country and there’s likely to be a few scattered showers in the north too. Elsewhere, it should stay largely dry with variable cloud, and some mist and fog patches forming, in a light northerly or variable breeze.
Met Éireann said there is some uncertainty in the detail of the forecast for mid-week but there’s likely to be some rain or showers at times on Wednesday (September 25) and Thursday (September 26), possibly heavy, and it will gradually turn colder.
Chilly, moderate to fresh, north to northeast winds will set in on Thursday also.
Thursday night will become dry with clear spells, apart from some showers continuing on Atlantic coasts. As the wind moderates, lowest temperatures will fall to between 4° and 7°.
There will be a chilly start to Friday (September 27) with sunshine and scattered showers following for the day. The showers will be most frequent in the north and west. It will be cool, with highs of 9° to 13°, with moderate northwest winds.
It will turn cold after dark on Friday night, with a touch of grass frost possible overnight, as temperatures fall to the low single figures.
Current indications suggest Saturday (September 28) will be a bright, cold day with sunny spells and a few scattered showers, and the chance of wet and windy weather for Sunday (September 29).
