Toronto's waking up to its first heat event of the season—and it's not done yet. The city and surrounding areas are facing hot, humid conditions Tuesday with temperatures climbing near 30°C and humidex values ranging from 33 to 35, according to forecasters.

The real wild card comes later today. Environment Canada is warning of possible severe thunderstorms, gusty winds, and a sharp cooldown expected to roll through parts of the GTA this evening. Residents are being urged to stay hydrated, avoid prolonged outdoor exposure during peak afternoon hours, and keep an eye on the sky as the day wears on.

This is the kind of weather that empties patios at 4 p.m. and sends everyone indoors looking for air conditioning. If you're planning outdoor plans, get them done before late afternoon. The humidity is real, the heat is real, and by tonight the whole dynamic shifts.

Stay hydrated and don't sleep on those storm warnings—they're coming.
