Rainfall is generally 5-10mm, some places over 20mm. During thunderstorms, beware of tornadoes, hail, strong gusts of wind around level 5-7 (8-17m/s), heavy rain causing localized flooding.
The thunderstorms are caused by the stable cold continental high pressure that gradually weakens in intensity. The low pressure trough with its axis through the Central region is compressed, weakened and gradually filled up. Above, the subtropical high pressure in the southern branch weakens. Disturbances above operate better, dominating the South.
The weather in the Southern region in the coming days will be cloudy, with scattered showers to heavy rain in many places with light to moderate rainfall, moderate rain; a few days with heavy rain in the early morning or late afternoon. Beware of the possibility of widespread rain in the early morning from October 3-4. Beware of tornadoes and gusts of wind during thunderstorms.
