Met Éireann is forecasting a change in weather conditions with temperatures falling and rain on the way in the coming days.
Met Éireann expects the heat to breakdown on Tuesday night into Wednesday as the Low pressure system moves up over Ireland steering in cooler air from the west for the rest of the week. This could also bring some wet conditions on Wednesday.
It says temperatures will return to normal from Wednesday onwards with a fair amount of dry weather and a few showers up to Friday.
As for the weekend, the signs are that it will become more unsettled with rain moving in from the southwest on Saturday evening and with further rain or showers on Sunday, it will be mild though with highs in the high teens to low twenties.
The forecaster's farming section gives more details.
They say rainfall will be above average for most areas due to showery rain on Tuesday, with more settled conditions for a time before more significant rainfall develops later next weekend. The south and west will be the wettest regions, with slightly less rainfall further north and east.
They say sunshine will be average or above in the coming week with sunny spells often developing between any showers.
Met Éireann says indications are that next weekend will become more unsettled with rain moving in from the southwest on Saturday evening and with further rain or showers on Sunday, it will be mild though with highs in the high teens to low twenties.
