It is currently Monday overnight in Plano, and the atmosphere remains thick with moisture and warmth.

Forecast for Today and Tomorrow

Today will be sunny with a high near 100°F. The National Weather Service indicates heat index values as high as 104°F due to the south wind around 10 mph, which may produce gusts as high as 20 mph. Temperatures are expected to drop to a low near 79°F tonight.

Overnight, skies will remain clear, and temperatures will rise slightly to around 81°F before climbing further to approximately 83°F later in the night. Winds will shift to south-southeast at 10 to 15 mph.

Tomorrow continues the hot trend with sunny skies and a high near 98°F. The heat index is forecast to reach 104°F again, driven by south winds of 10 to 15 mph with gusts up to 25 mph. Lows will settle near 82°F tomorrow night, with clear skies allowing temperatures to rise to around 84°F overnight. There is no chance of precipitation for either day.

Safety and Awareness

With heat indices exceeding 100°F, the risk of heat-related illness increases significantly. It is crucial to stay hydrated by drinking water frequently, even if you do not feel thirsty. Limit outdoor exertion during the hottest parts of the day, typically between late morning and early evening.

Wear lightweight, light-colored clothing and seek air-conditioned environments when possible. Check on elderly neighbors or those without adequate cooling, as high humidity can make indoor temperatures feel oppressive even with fans running. No active weather alerts are currently in effect for this area.
