Sunny conditions are set to continue in Northern Ireland today with highs of 17C predicted.
After a chilling start to Monday, with temperatures in some places dipping to -1C,the Met Office says there will be lengthy cloudy spells on Tuesday, with some scattered showers.
It will also be rather cloudy on Wednesday with more scattered showers.
However, warm and sunny spells are set to continue on Thursday and Friday.
The Met Office said: "Conditions will be rather changeable with some sunshine but also areas of rain or showers.
"Thunderstorms are also likely in places. Many parts will become warm, perhaps very warm, particularly northwestern areas.
"However, mist and low cloud will probably affect east coasts at times, making it cooler here. For the rest of the period confidence is low."
