Overnight temperatures are expected to dip to as low as -4c in parts of Clare this weekend as the cold, dry spell continues.
The first cold spell of the winter is set to continue into the middle of next week at least with forecasters suggesting the next rainfall event may not occur until Thursday night into Friday morning.
Conditions are expected to turn cooler and more settled again for the following weekend.
In the meantime, the Road Safety Authority is warning motorists to be aware of the danger of black ice and to slow down while driving through patches of freezing fog.
Over the coming few days, daytime temperatures are forecast to climb to 6-8c but will remain closer to freezing where any fog persists.
At 10pm on Friday night, it was -1c at Shannon Airport while it at 10.30pm it was -1.5c in Crusheen.
