Weather forecasters expect the summer weather to desert us for most of the rest of the week but warmer weather could be building from the south come the weekend.

Met Éireann's weather forecasting partner in the UK, the Met Office, says a slow-moving low-pressure system to the north of Ireland and Britain will bring windy and wet weather.

Wednesday looks like being the worst of the days but there could be more rain on Thursday. 

Met Éireann says Wednesday will start cloudy and wet in most areas with outbreaks of rain quickly extending eastwards. The rain will turn more showery in the afternoon and evening with some bright or sunny spells developing in the west.

Anyone golf fans travelling to the Open Championship in Portrush would do well to pack the wet gear for the weekend.

The Met Office predicts that warm weather will build from the south of Ireland and Britain Saturday and Sunday while Met Éirean expects some bright or sunny spells over the weekend. However, the Irish forecaster is warning about showers too, some of these heavy, especially inland, with a few prolonged and possibly thundery.

Top temperatures could reach the low twenties and it will feel close and humid at times. Winds light to moderate south to southwesterly. The weekend nights will also be humid with temperatures in the low to mid-teens. Further rain or showers each night also. MORE BELOW TWEET
