The Easter holidays are set to get off to a glorious start today with clear skies for most and temperatures reaching 17 degrees in places - but the sunny weather will be short-lived as a grey and damp week is set to follow.
Met Office forecaster Callum Stewart explained that high pressure hovering over Europe is bringing warm air up from the continent which - coupled with the sunshine - will send the mercury soaring in many parts of the UK, but Northern Ireland won't be feeling the heat.
"The best day for Northern Ireland will be Saturday," he said.
"There should be plenty of sunshine and not much cloud around at all really. It will be warmest in the west where temperatures will get as high as 17 degrees.
"Eastern areas will not be quite as warm but should still feel pleasant in the sunshine with the temperature getting into the mid-teens."
The best of the weather is reserved for the south of England where it is expected to be as hot as 23 degrees - with the possibility of several spots seeing temperatures peak at 24 degrees - but it isn't going to last.
Mr Stewart said the week ahead looks set to be dismally grey with the risk of April showers, adding: "Sunday will not be as good due to significant cloud cover which will also bring a risk of outbreaks of rain in the afternoon. This trend will continue for much of the week ahead."
