Met Éireann meteorologist Joanna Donnelly has said that there will be a return to higher daytime temperatures over the next few days.
Speaking on RTÉ's Today with Claire Byrne, Ms Donnelly explained that the jet stream is the driver of Ireland's weather.
The jet stream is a name used to describe a pattern of fast-flowing currents of air above the Earth's surface that impact on winds and pressure, which influences the weather we experience in Ireland, among other places.
When the jet stream is flowing predictably, it lowers the pressure in the atmosphere which brings stronger winds and more stormy weather.
However, when the jet stream begins to flow unpredictably, it causes areas of high pressure to arise, which typically brings less stormy weather, light winds and dry skies.
Ms Donnelly said as the jet stream has not yet been pushed far enough north this year, we have not had the warmer temperatures that we would expect.
She added that the temperatures are starting to rise and over the next few days we should have higher daytime temperatures.
Apart from a weather front on Tuesday, she said, the weather should improve "so it looks like it's going to stay".
She said that when a high pressure gets established it tends to stick around for a while and "at the moment it looks like it'll stay with us".
Met Éireann has said that today will be mostly dry but cloudy, with some patchy rain or drizzle. There will be some bright spells in the east and southeast however.
A good deal of dry weather is expected tomorrow but it will be cloudy with some rain at times, especially for the northwest. Temperatures will range from 17 to 23 degrees.
The forecaster has said that it will be dry in many areas on Friday with isolated showers, with better sunshine later in the day, most likely in the south. Highest temperatures of 17 to 23 degrees.
It expects warm and dry weather for most parts over the weekend, with a mix of cloud and sunshine.
Temperatures on Saturday will range from 19 to 23 degrees, while on Sunday temperatures of between 20 to 24 degrees are expected.
The warmer conditions are expected to continue into the beginning of next week also.
"The early days of next week are looking to bring a lot of dry weather with temperatures in the low, possibly mid, 20s.
"Somewhat cooler for the western and northwestern areas where it may be cloudier, with a chance of rain there on Tuesday," Met Éireann said.
