Current Conditions and Immediate Heat
Dangerous heat is currently gripping Melissa, Texas, as the afternoon sun beats down on the community. The air temperature stands at 97F, but the heat index pushes the perceived temperature to a stifling 101F. This significant disparity between the actual air temperature and how hot it feels is driven by a combination of high heat and moderate humidity, with the relative humidity currently at 37% and a dew point of 66F.
Conditions remain clear overhead, offering no relief from the direct solar radiation. Winds are active, blowing from the south at 18 mph with gusts reaching 20 mph. While the breeze provides some mechanical cooling, the underlying thermal load remains intense. Residents are advised to recognize that the body’s ability to cool itself is compromised when the heat index exceeds 100F, making hydration and limited exertion critical during these peak afternoon hours.
Forecast for Today and Tomorrow
The National Weather Service indicates that the intense heat will persist through the rest of today. The high is expected to reach near 99F, with heat index values climbing as high as 102F. South winds will continue around 15 mph, with gusts potentially hitting 25 mph. There is a zero percent chance of precipitation, ensuring the sky remains sunny and clear.
Tonight, conditions will stay clear with a low near 79F. However, temperatures may rise to around 81F overnight, keeping the heat index as high as 101F. South winds will ease slightly to 10 to 15 mph, with gusts up to 25 mph. The lack of a significant drop in temperature means the heat will linger into the night.
Tomorrow, the region will see a slight reprieve in the peak air temperature, with a high near 97F. Despite the lower air temperature, the heat index will still reach as high as 102F. Winds will shift to the south southwest at around 10 mph. The sky will remain sunny with only a 1% chance of precipitation. Tomorrow night will be mostly clear with a low around 79F, and temperatures rising to 81F overnight, with a heat index up to 100F. Winds will decrease to 5 to 10 mph from the south.
