National Outlook

A mainly southerly airflow persists through the outlook period. Temperatures dipping back to near average by Monday, but milder than average again towards midweek next week.

Sunday night: Cool with clear spells and scattered showers. Minimum temperatures 4 to 7 degrees in mostly moderate southwesterly winds, fresh to strong and gusty at the coasts.

The showers, some of them heavy with a risk of hail and thunder, will be widespread in Connacht and Ulster, but they will tend to be more scattered elsewhere. Highs of 8 to 10 degrees, in moderate southwest to west winds. Showers becoming isolated on Monday night and turning cold under clear spells. Light to moderate southwesterly breezes will back to a mostly light southerly by morning. Minimum temperatures of 0 to 4 degrees with a risk of frost. Cloud will, however, thicken from the Atlantic towards dawn which may mitigate the frost risk in western areas.

Tuesday: Cloudy or becoming cloudy during the morning. Scattered outbreaks of rain and drizzle will extend from the Atlantic to all parts through the course of the day, with persistent and heavy falls possible in west Connacht and west Munster. Highs of 7 to 10 degrees. Moderate southerly winds, freshening on Atlantic coasts. Mostly cloudy on Tuesday night with further outbreaks of rain and drizzle. Lows of 5 to 8 degrees in moderate to fresh and gusty southerly winds, strong to near gale at the coasts.

Wednesday: Often cloudy with occasional rain, drizzle and mist, but some drier and brighter intervals also, especially towards evening. Mild, with highs of 10 to 13 degrees in blustery southerly winds. Largely dry with variable cloud amounts and clear intervals on Wednesday night. However, a few mist and drizzle patches will also occur, mainly in southern and southeastern coastal counties. Lows of 7 to 10 degrees in mostly moderate southeasterly winds.

Further outlook: Current indications suggest a milder than average Atlantic type regime is likely to prevail through the rest of the week and into next weekend. Wet and breezy conditions will alternate with drier and brighter interludes.
