  "account": "Toronto is beginning September under a dense fog advisory and a humidex nearing 40, as Environment Canada warns of scattered showers and thunderstorms. The yellow-level fog advisory, issued late Monday and lasting into Tuesday, cautions of near-zero visibility in areas including Toronto, Pickering-Oshawa-Southern Durham, and Vaughan-Richmond Hill-Markham. Visibility is expected to clear later in the morning, but mist and fog from the early hours have made commuting difficult. Local authorities advise drivers to reduce speed and use headlights. Once the fog lifts, Toronto can expect a mix of clouds, sunny intervals, and scattered showers, with the potential for thunderstorms throughout the day. High temperatures will reach 28°C, but the humidex will climb to 36, making it feel much hotter and marking the beginning of a muggy stretch. Despite the cloud cover, conditions remain partly cloudy with a continued threat of thunderstorms, and a warm overnight low of 20°C. On Wednesday, the heat and humidity will persist, with showers and thunderstorms forecasted, along with a high of 28°C and a humidex of 37. Overnight temperatures will dip to 18°C, offering little respite from the humidity. On Thursday, the weather will remain mostly cloudy with a potential for showers or thunderstorms, and a high of 26°C. Friday will be calmer and drier, with a mix of sun and cloud, and a high near 26°C, providing the first respite from the unsettled weather pattern.
