Today's high reaches 110°F — a figure that changes how you plan every hour of your day. This episode breaks down exactly what that means for your safety, your commute, and your routine.Humidity is running between 10 and 12 percent, a deceptively dangerous level where sweat evaporates faster than your body registers thirst. Winds of 10 to 15 mph from the south and southwest won't cool you down — at 110°F, warm wind accelerates moisture loss. The UV index sits at 10, classified as very high, with peak sun exposure from 10 AM through 4 PM.For what to wear: light, loose, pale-colored clothing, a wide-brimmed hat, and UV-blocking sunglasses. SPF 50 or higher sunscreen is non-negotiable today. For your commute, get moving before 9 AM if you can — the 2 to 5 PM window is peak danger. Confirm your vehicle's AC is working before you leave. A breakdown today without air conditioning is a medical risk.Fire danger is extreme at this humidity level. Avoid outdoor burning and be cautious with grills. Hydrate steadily throughout the day rather than in large amounts at once. Check on elderly neighbors and pets — both are especially vulnerable in sustained extreme heat.The warning remains fully active with no rain system developing and no confirmed end date. Stay hydrated, plan early, and keep outdoor exposure short.This episode includes AI-generated content.
