Dangerous Heat and High Humidity

Denison is currently under the influence of dangerous heat conditions this afternoon. The air temperature stands at 99F, but the combination of heat and moisture pushes the feels-like temperature to a hazardous 106F. This elevated heat index underscores the severity of the current weather pattern, where the body struggles to cool itself effectively.

Forecast for Today and Tomorrow

The National Weather Service indicates that sunny skies will continue to dominate the region. Today, the high is expected to reach near 97F, with a low near 80F. The chance of precipitation is minimal at 8%. While the official forecast notes heat index values as high as 102 during the day, the current feels-like temperature already exceeds that threshold.

Tonight, conditions will remain mostly clear with a low around 80F. Heat index values are expected to stay as high as 102. Winds will shift to the south, ranging from 5 to 10 mph. Tomorrow, the heat will persist with sunny skies and a high near 98F. The chance of rain drops to just 1%. Heat index values may climb as high as 103.

Safety Reminder

Given the dangerous heat index values, it is critical to stay hydrated and limit midday exertion. Seek air-conditioned environments whenever possible and check on vulnerable neighbors. The combination of high heat and humidity poses significant health risks, so please take necessary precautions to stay safe.
