Cold air mass to drive temperatures downStaff writer, with CNAA strong continental cold air mass is to move southward from tonight night into tomorrow, bringing overnight temperatures in low-lying areas across Taiwan down to about 10°C to 14°C, the Central Weather Administration (CWA) said. In Taichung, Nantou County, Yunlin County, Chiayi County, Tainan and Kaohsiung, temperatures could drop below 10°C early tomorrow morning due to radiative cooling, the agency said. Taiwan is to remain under the combined influence of the cold air mass and radiative cooling through Thursday, Cheng said. While the cold air is expected to weaken slightly on Friday and Saturday, radiative cooling would continue to keep temperatures low. Daytime highs in northern Taiwan could return to about 20°C, although parts of western Taiwan may see day-night temperature differences of 10°C to 13°C.
