It might be time to dig out your winter coat...

According to Dublin Live, forecaster Alan O'Reilly of Carlow Weather has warned that much cooler air will move across the country from Wednesday.

And while the rain is expected to ease, it will make way for some seriously chilly nights.

When will the cold snap hit Ireland?

Met Éireann expects Tuesday to start mostly cloudy and dry, before rain and drizzle develop later in the day.

The weather will begin to change on Wednesday, with mostly dry conditions, sunny spells and temperatures reaching between 9C and 11C.

However, overnight temperatures could fall to between 0C and 5C, with frost developing in some areas.

Thursday is expected to be even colder, with daytime highs of just 6C to 9C.

And once the sun goes down, temperatures could plunge to -2C under mostly clear skies.

O'Reilly warned that colder air would follow the rain as it clears the country.

"Much cooler air moving down Thursday with a biting windchill," he said.

What about Friday?

The chilly conditions are expected to continue into Friday, although the weather should remain mostly dry.

Sunny spells are forecast for much of the country, with cloudier conditions in northern areas.

With temperatures dropping below freezing in some places, motorists may also need to allow a little extra time to clear frost from their windscreens in the morning.
