The strong winds beginning to batter much of Northern Ireland on Friday evening are expected to continue into Saturday morning and a yellow weather warning has been issued.
Snow has also fallen on high ground, mainly in Counties Londonderry, Antrim and Down.
It is expected to remain chilly on Saturday morning with wintery showers and a maximum temperature of 5C throughout the afternoon.
Sleet will gradually turn into rain towards midday as milder air spreads from the west, according to the Met Office.
The major downturn in the weather picture has been described as “temporary” by forecasters, following what has been an exceptionally mild first few weeks of November.
Saturday will be a much brighter day but temperatures are not expected to rise to more than 8C. Rain is expected to sweep across the Province on Monday but it will be much milder.
Motorists in Scotland and northern England have been advised to exercise particular caution as temperatures on Friday are expected to fall below zero in many areas.
