"Afternoon temperatures will only reach around 3C to 7C degrees", the forecaster said.
FRIDAY NIGHT: Continuing dry with clear spells.
Daytime temperatures will feel quite warm, while winds will stay mostly light, although coastal areas will feel more chilly amid a maximum of 14C.
Any mist or fog will clear tomorrow morning (Saturday, April 3) for a dry and settled day with good sunshine.
Dry and settled conditions will predominate for the Easter weekend, but it will turn colder and more unsettled after Easter Sunday.
"Friday will be a dry day with long spells of spring sunshine and highest temperatures generally of 12C to 16C degrees, being warmest in the southwest", she said. Rain will develop in the northwest later in the morning and will extend across the northern half of the country during the afternoon and possibly further south into the evening. Afternoon temperatures will range 8 to 13 degrees but it will gradually become much colder from the northwest during the evening, so some falls of sleet will be possible in Ulster then.
SUNDAY NIGHT: Sunday night will be cold and breezy.
It's not unusual to see big swings in temperature across the United Kingdom in spring, however there will be a notable change in temperature as the warm air across the south is displaced.
Easter Sunday will be dry over much of the country with the best of the sunshine in the south.
On average, the United Kingdom experiences around 14 days each spring where temperatures fall to zero or below, revealed the forecaster.
The end of the bank holiday weekend will herald colder weather, however, with the Met Office forecasting bands of cold Arctic air moving across the United Kingdom from the north west by Sunday, bringing snow showers and freezing overnight temperatures.
The outlook for Easter Monday here is some snow showers, with spells of hail showers, indicating the arrival of a brief "spring cold snap". Lowest temperatures of -2 to +2 degrees with fresh to strong and gusty northerly winds. Highest temperatures will be 5° to 8° with light to moderate west to northwest winds.
