The National Center for Hydro-Meteorological Forecasting said that a strong cold air mass is moving, and will spread to the Northeast region early on February 7, then expand to the plains and Northwest. Because the North has been immersed in a cold air mass that has intensified since the night of February 2, combined with this new mass, the temperature will drop very low. The coldest temperature in the highlands is forecast to be below 2 degrees Celsius, in the mountains and midlands 5-8 degrees Celsius, and in the plains 9-12 degrees Celsius. Snow and frost may occur in the mountains.
