Weather patterns in Spain and Argentina continue to undergo significant shifts. In Spain, the Canary Islands expect rising temperatures alongside occasional rain in northern mountainous areas. Madrid remains stable but is preparing for a temperature increase over the weekend. The Community of Madrid has issued a preventive warning to municipalities to inspect drainage systems in anticipation of autumn rains to avoid flooding incidents similar to past river overflows.

A warm air mass is forecasted to cause a sharp thermal shift across the peninsula; temperatures in the north and interior are projected to rise by 8 to 10°C, bringing summer-like conditions. While instability and showers may persist in the Mediterranean, the Balearic Islands, and parts of the southeast, high pressure is expected to stabilize much of the country, with some southwestern areas potentially reaching 35°C. Additionally, the Baix Llobregat region has seen yellow alerts for morning rain.

In Argentina, Tucumán expects warm temperatures with a low probability of evening showers, while Neuquén continues to see rising temperatures and wind in the cordillera. In La Banda, a cloudy Friday with a high of 30.1°C is expected to transition into a sunny weekend, with temperatures projected to reach a maximum of 34.9°C by Sunday. Other regional updates indicate variable cloudiness and fog in northeast Uruguay, while Venezuela faces widespread rain and electrical activity driven by the Intertropical Convergence Zone, with Inameh reporting potential thunderstorms particularly in Bolívar, Amazonas, and Zulia.
