¶Weather: Smoke haze is lingering over Perrysburg tonight (low around 66°), a holdover from the Canadian wildfire smoke that’s been fouling Midwest air quality all week. Sunday looks better — mostly sunny with a high near 81 and patchy smoke not moving back in until afternoon. Rain returns Monday night into Tuesday, with highs climbing into the mid-80s first.

¶Headlines: The big story overnight is the US and Iran exchanging strikes over the Strait of Hormuz, with CENTCOM hitting military infrastructure near Bandar Abbas and Iran striking a Kuwaiti desalination plant — a grim turn less than a month after the two countries signed a preliminary deal to stop fighting. In the UK, Andy Burnham was confirmed as Labour leader and is set to be sworn in as prime minister Monday, becoming Britain’s seventh PM in a decade.

¶On the science side, astronomers confirmed the first atmosphere ever detected on a rocky, habitable-zone exoplanet — LHS 1140b, 49 light-years out — based on helium escaping the planet, a genuinely big deal for the search for life elsewhere. Closer to home, wildfire smoke from Canada’s brutal fire season continues to choke air quality across the Midwest and Northeast. In sports, the World Cup wraps up this weekend: France plays England in today’s third-place match, with Argentina facing Spain in Sunday’s final, and the WNBA’s Caitlin Clark put up the first 40-point, 10-assist game in league history against Seattle.
