Late yesterday and overnight a very cold southerly outbreak crept north over the country seeing thermometers nosedive.
Scenes more reminiscent of mid-July have taken hold of areas already affected by this mass of polar air.
Showers of rain, hail, sleet and snow have fallen across many districts in the south and east of the mainland, with only a gradual improvement expected today.
Southerly winds have also been bitterly cold and blustery in exposed areas, making conditions more miserable.
Alpine roads in southern and central regions have been affected by some snow and the Desert Road is likely to see problems today as well.
Single figure highs are likely to be on the cards in those areas vulnerable to the icy winds and wintry overhead conditions.
The good news is that it appears relatively shortlived and within 24 hours most of the country should see some sunshine, although some chilly temperatures are anticipated for a day or two.
