Highest temperatures over Leinster and Munster will range 16 to 20 degrees Celsius. Meanwhile, Connacht and Ulster will see temperatures of between 13 to 17 degrees. After a mainly dry start to this week, it will gradually turn more unsettled as the week goes on with spells of rain developing, according to the forecaster. Tuesday will see a dry and bright start to the day but cloud will build from the north through the morning and afternoon with outbreaks of rain and drizzle developing over the northern half of the country towards the evening. Highest temperatures will reach 13 to 18 degrees, coolest over the northern half of the country and warmest in the south.
