The fall in temperatures this week will last for five days, with Thursday seeing the coldest readings.

Urban areas will experience a low of 10 degrees Celsius, while it will be a few degrees cooler in northern parts of the New Territories as the second cold snap of the winter sets in.

The Observatory says today's low will be about 13 degrees and the mercury will continue to drop until Thursday. It will become warmer on Friday and Saturday. A cold winter monsoon from the mainland is responsible for the gradual fall in temperatures.
