A cold air mass is moving northwards across Argentina, set to trigger several days of unstable weather conditions. The majority of central and northern Argentina will experience precipitation as a result. Wednesday will be the day with the most significant temperature contrast. The northeast region is forecast to receive up to 140 millimeters of rainfall by Friday. This system will bring thunderstorms, electrical activity, and potentially hail to affected areas. Residents should prepare for challenging weather conditions and potential disruptions. Authorities are monitoring the situation closely.
