A BLAST of polar air will send temperatures dipping as low as -5C next week, with motorists warned to be wary of treacherous 'black ice'.
Temperatures are set to drop even lower in the coming days as northerly winds send gusts of chilly air from the east of Iceland blowing across the country.
So far this month, the mercury levels have plunged as low as -3.1C in Moorepark, Co Cork.
Met Eireann forecaster Eoin Sherlock said temperatures were likely to plunge as low as -5C overnight on Tuesday due to the polar air flow, with daytime temperatures between 2C and 5C.
However, the forecaster said at the moment it appeared unlikely there would be any "large snowfalls" but there may be a chance of snowfalls on higher grounds near the east and north coast early next week.
Gardai and the Road Safety Authority (RSA) have urged caution on the roads following the recent frosty nights, with plummeting temperatures leaving treacherous patches of 'black ice' in places.
A spokesman for the RSA warned if a road appears polished or glossy, then there could be a patch of 'black ice' lurking.
