Rain will develop across Munster and south-Leinster this evening and early tonight, and then the rain will gradually extend northwards overnight. Lowest temperatures of 9 to 12 degrees in freshening east to southeast winds.
Rain will clear from Ulster and north-Leinster tomorrow morning and the cloud will slowly break-up. Good sunshine will continue to occur in many places through the day, but heavy showers will break out during the afternoon and evening. It'll be fairly warm with highest temperatures of 15 to 17 degrees in southerly breezes.
Monday night will see rain continuing in all areas for a time. However, the rain will clear north across the country overnight, leaving showers in its wake. During Tuesday, the showers will become more widespread and occasionally heavy, with a risk of isolated thunderstorms breaking out also. There will be a tendency for showers to become prolonged as the day goes on also, and to persist well into the night in northern and eastern areas. On Wednesday morning, any rain in the east and north will soon clear and the day will be dry and bright, apart from isolated showers in western counties. Wednesday night and all of Thursday will be mainly dry with well broken cloud. Friday will start dry in all areas but rain will reach western counties in the morning and will then spread eastwards during the rest of the day. There is likely to be further rain in most parts of the country throughout next weekend.
Temperatures will be near normal on most days this week, although Wednesday will feel a little cooler. Wednesday night may even see some grass frost inland but all other nights will be mild. Winds will vary a lot initially with fresh, west to northwest breezes on Tuesday giving way to moderate, southwest to south winds for Wednesday and Thursday. Winds will back south to southeast on Friday and will strengthen everywhere, with gales likely to develop in exposed parts of the west for a time.
