Between December 20 and 29, northern Vietnam will experience alternating weakening and strengthening cold fronts, leading to extended chilly nights. Central and southern regions may face thunderstorms and rain due to a developing low-pressure system.

Meteorologists from the National Center for Hydro-Meteorological Forecasting predict a continental cold air mass will stabilize, weaken, and then strengthen between December 21-22. Another wave of cold air is likely in the final days of December. Meanwhile, a low-pressure trough will form to the south and gradually shift northward, increasing its activity.
