Current Conditions and Heat Index

It is currently Thursday this afternoon in Van Alstyne, TX, where temperatures are already pushing the limits of comfort. The air temperature stands at 93F, but the combination of heat and moisture makes it feel significantly warmer. The current feels-like temperature is 99F, driven by a relative humidity of 47% and a dew point of 70F. These conditions create a muggy atmosphere despite the clear sky overhead.

Wind is providing minimal relief, blowing from the south southwest at 10 mph with gusts reaching 14 mph. While the sun is out, the humidity levels indicate that the air is holding a substantial amount of moisture, which will contribute to the oppressive heat index values expected throughout the day.

The National Weather Service forecasts a sunny day today with a high near 100F. The heat index is expected to climb as high as 104 during the afternoon hours. Winds will remain in the south southwest at 10 to 15 mph. The chance of precipitation is minimal at just 1%, ensuring clear skies continue to bake the area.

Tonight, conditions will remain clear with a low around 78F. Temperatures are expected to rise to around 80F overnight, keeping the heat index as high as 103.

Safety Reminder

With heat index values exceeding 100F, residents should take precautions against heat-related illnesses. 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 10 a.m. and 4 p.m. If you must be outside, seek air-conditioned spaces regularly and wear lightweight, light-colored clothing. Check on elderly neighbors or those with health conditions who may be more vulnerable to the heat. There are no active weather alerts, but the extreme heat itself poses a significant risk to health and safety.
