\nThe first half of June 2025 saw Europe and North America rocked by dramatic weather events: violent tornado outbreaks, intense hailstorms, flash floods, record-breaking heat, and wildfires. Atmospheric dynamics were driven by persistent heat domes, strong cold fronts, and favorable jet stream patterns that fueled convective storms\u2014a trend confirmed by ECMWF, Severe Weather Europe, NOAA, and national weather services.<\/p>\nEurope 2025 (June 1\u201315)<\/h2>\n
