Weather forecast for the next 24-48 hours, a low pressure trough with an axis of about 25-28 degrees North latitude connected to the hot low pressure area to the West will be compressed and gradually move southward, and at the same time fill up due to the influence of continental high pressure from the North.
In the South, a low pressure trough with an axis of about 8-10 degrees North latitude forms and tends to raise its axis to the North. Southwest winds in the South area operate with weak to moderate intensity. Above, the subtropical high pressure continues to raise its axis to the North, passing through the North Central and Northern regions.
Weather forecast from 3-10 days, a low pressure trough with axis of about 25-28 degrees North latitude will continue to gradually fill up. Meanwhile, a low pressure trough in the South with axis of about 9-12 degrees North latitude is more active when passing through the Southern region.
In the last 1-2 days of the period, this low pressure trough tends to raise its axis to the North through the Central region and then gradually weaken. Southwest winds in the South will gradually become stronger. Above, the subtropical high pressure maintains its axis through the North and operates strongly; around May 28-29, it is likely to encroach westward.
Therefore, around May 27, the heat in the South will gradually decrease. The probability of thunderstorms will also increase. Thunderstorms may be accompanied by tornadoes, lightning, hail and strong gusts of wind, affecting agricultural production, causing trees to fall, damage to houses, traffic works and infrastructure. Flooding may occur in some areas, causing traffic congestion, affecting daily life and crops.
