WE'RE about to be hit by our first cold snap of the autumn ... just in time for the bank holiday weekend.
Temperatures are expected to plummet by up to 5C below what's normal for this time of year. And Met Eireann has warned that temperatures could drop to --3C tonight.
The Road Safety Authority and gardai have urged road- users to take extra care over the Halloween weekend, as widespread frost and some icy patches are expected.
The cold snap will continue into next week and daytime temperatures will be 4C lower than normal for late October and early November.
"There is no doubt about it that the weather will feel cold and temperatures will be lower than expected," said Siobhan Ryan of Met Eireann.
However drivers, and the public, will be relieved to hear that no dramatic weather conditions are expected over the Halloween break.
A drop in temperatures could lead to a dusting of snow on higher ground overnight, and there will be a chilly easterly airflow in the greater Dublin region.
Met Eireann explained that a "north easterly airflow is always a bit disappointing for the greater Dublin region as this can often result in dull weather and rain showers".
For those planning to enjoy the Halloween festivities this week, night time temperatures are more reasonable for this time of year.
The cold weather will be worsened by the onset of darkness earlier in the evenings as the clocks turn backward by one hour on Sunday.
Sunday itself is expected to be damp and dull, with outbreaks of rain.
However, it's better news on Monday as the cloud is expected to clear away and the day will be mainly dry for those hoping to make the most of the bank holiday.
