Starting today (January 15), the cold wave will gradually show its "cooling" strength. Today, the north will enter the core cooling period.

In terms of rain and snow, snowfall continues today in the Northeast, with heavy snowfalls in some areas. The southern rain and snow have increased significantly on weekends. The public should take precautions when going out.

The cold wave is coming and the temperature in the central and eastern regions will be "big dive"

　　Since mid-January, the temperature has shown an overall upward trend, and most of them have become warmer. Although it is in the "three to nine days", some places are as warm as March or even April.

This untimely warmth often means that the temperature "full reduction" is about to start again.

　　Compared with the cold wave from January 6 to 8, the absolute strength of this cold air is weaker, but because the base temperature before cooling is significantly higher, the cooling rate is large.
