The weather is forecast for the next 24-48 hours, the low pressure groove connects to the Western low pressure area, from 9.5, the low pressure trench is compressed by the continental high-pressure high pressure unit in the north and pushes the translation to the south.
The southwest wind will operate at a weak intensity. The subtropical high pressure has little change in intensity. From around May 9, a wind convergence will form at an altitude of 1,500m in the Northern region.
Weather forecast for the next 3 days, the low pressure trough with an axis at about 24-26 degrees North latitude will continue to be compressed, pushing the epidemic to the South due to the continental cold high pressure in the North, then gradually filling up.
From around May 12, the continental high pressure will weaken; around May 13, a low pressure trough will form with an axis at about 23-26 degrees North latitude, then be weakly compressed.
The weak to moderate southwest wind will continue to remain in the southern area. Above, the subtropical high pressure will be stable, from around May 10-11, it will weaken and gradually withdraw to the East.
Therefore, the Southern region tends to have more and more frequent thunderstorms, with moderate and heavy rain. From now until May 13, the probability of rain is 70%.
