Dangerous Heat Conditions Underway

A Heat Advisory is currently in effect for Melissa, Texas, signaling dangerous heat conditions that require caution. The National Weather Service has issued this moderate-severity alert, which remains active until the evening of tomorrow. The advisory highlights the risk of heat-related illnesses as temperatures and humidity combine to create hazardous conditions.

Current conditions in Melissa reflect the intensity of the heat. The air temperature stands at 97F, but the combination of heat and moisture makes it feel like 105F. The relative humidity is at 44%, with a dew point of 72F, indicating significant moisture in the air that hinders the body's ability to cool itself.

Winds are blowing from the south at 12 mph, with gusts reaching 13 mph, under a clear sky.

Forecast for Today and Tomorrow

Today, the sun will remain out with no chance of precipitation. Highs will reach near 100F, while the heat index is expected to climb as high as 108F. South winds will persist around 10 mph. As tonight approaches, skies will become mostly clear with lows near 79F. The heat index will remain elevated, staying as high as 106F, with south winds continuing around 10 mph.

Tomorrow, the pattern remains consistent with mostly sunny skies and a high near 100F. The heat index is forecast to peak at 109F, making this the most intense day of the advisory period. South southwest winds will blow around 10 mph. Tomorrow night, conditions will ease slightly with mostly clear skies and lows around 79F, though the heat index will still reach 106F.

Safety Reminders

Given the active Heat Advisory and the high heat index values, it is critical to stay safe. Hydrate frequently by drinking water even if you do not feel thirsty. Limit outdoor exertion, especially during the midday hours when the sun is strongest.

If you must be outside, seek air-conditioned spaces or shade whenever possible. Check on neighbors, particularly the elderly and those without air conditioning, to ensure they are safe. Wear lightweight, light-colored clothing and apply sunscreen if you are exposed to the sun for extended periods.
