According to Focus Taiwan, Cheng Chieh-jen, a CWA forecaster, stated that a relatively warm easterly wind system is expected to continue, bringing sunny to cloudy skies around Taiwan and boosting temperature highs to 23-25 degrees Celsius in the north and east and 27-28 degrees in central and southern Taiwan.

With radiative cooling, which refers to the cooling of the ground under clear skies, light winds, and dry conditions, the mercury on Thursday night is forecast to fall to 12-15 degrees in western Taiwan and 16-17 degrees in the east, Cheng noted.

Some areas in Taoyuan City and Hsinchu and Miaoli counties in the north could experience nighttime temperatures dipping below 10 degrees, he added.

The CWA has issued a “yellow” cold surge advisory for Taoyuan, Hsinchu, and Miaoli, which is expected to remain in effect until Thursday morning.

Cheng mentioned that a similar weather pattern is likely to continue into the weekend, although sporadic showers are possible in the east. A northeasterly seasonal wind system is forecast to set in on Monday, potentially destabilizing the weather, with a continental cold air mass or a strong continental cold air mass expected to follow on Tuesday, leading to a drop in temperatures.

Cheng also reported that the first tropical depression of the year formed southeast of the Philippines on Wednesday morning and is likely to develop into a tropical storm. However, the weather system could dissipate as it moves north, and it is not expected to affect Taiwan.
