This week is going to start off settled, according to Met Éireann, before the weather turns colder, windier and much more showery by the end of the week.
Monday - It will be cold to begin with on Monday, with mist lifting early and leaving a predominantly dry day, with sunny spells and variable cloud cover. There is a risk of some light showers falling in west Ulster, though it should remain dry for the majority of areas. Winds will be westerly and fresh at times mainly in northern coastal counties, though they should remain moderate elsewhere. Top temperatures on the day of 11 to 14 degrees Celsius.
Monday night will remain dry for the most part, with clear spells and only the occasional mist pockets forming. Minimum overnight temperatures of 4 to 8 degrees, with moderate to fresh westerly winds.
Tuesday - Another dry day for the most part, with good sunny spells forecast for most areas. There will be some cloud cover, especially in northern and western coastal counties, which could bring some patches of rain. Top daytime temperatures of 12 to 16 degrees with moderate westerly winds, again fresher and even increasing to strong along northern coastal counties.
Tuesday night will be mainly cloudy and quite misty with some fog also forming in places. It will, however, remain dry with just the occasional patch of rain or drizzle. Minimum temperatures overnight of 5 to 8 degrees with moderate winds, west to northwest in direction.
Wednesday - A cloudy day forecast for Wednesday, with the odd sunny interval. It should remain dry countrywide, with the occasional light shower falling, mainly in northern counties. Mist is likely to linger throughout the day on hills and along some coasts. Top daytime temperatures of 11 to 14 degrees, with moderate west/northwest breezes.
Thursday - Early indications suggest another cloudy day is likely on Thursday, especially in the north and west of the country, with some patchy rain or drizzle likely. It should remain predominantly dry elsewhere, with some good sunny spells and top temperatures on the day of 11 to 13 degrees. Winds will be moderate and west or southwest in direction.
A much colder night forecast for Thursday with a cold front approaching the west coast early in the night and rain becoming persistent in the north and west of the country. This cold front and rainfall will then sweep southeastwards during the night, introducing what Met Éireann call a much colder “arctic airmass” across the country.
Friday - Any lingering rain should clear early on Friday, leaving a cold and windy day overall with some sunny spells and widespread showers. Some showers are likely to be heavy, with a risk of hail and thunder, especially in northern and western coastal counties. Maximum temperatures on the day of just 7 to 11 degrees, with fresh and blustery northwesterly winds.
