Current Conditions and Alert Status

Residents in Prosper, Texas, are under a Heat Advisory this Saturday morning. The National Weather Service has issued this moderate-severity alert due to dangerously high temperatures and humidity levels that will make the air feel significantly hotter than it actually is.

Right now, the air temperature stands at 91F, but the heat index pushes the feels-like reading up to 99F. Humidity is also playing a major role in how oppressive the heat feels, with a dew point of 72F and relative humidity at 53%.

The sky remains clear overhead, while winds from the south southwest are blowing at 10 mph, with gusts reaching up to 14 mph.

Forecast for Today and Tomorrow

Conditions will remain hot and sunny through the rest of today. Highs are expected to reach near 100F. The heat index is forecast to spike as high as 106 during the peak afternoon hours. Winds will continue from the south southwest around 10 mph, with gusts potentially hitting 20 mph. There is only a 1% chance of any precipitation.

Tonight, skies will turn mostly clear, allowing temperatures to drop to a low near 81F. However, the heat will linger, with temperatures rising to around 83F overnight and heat index values staying as high as 104. Winds will shift slightly, blowing from the south southwest at 10 to 15 mph.

Tomorrow brings even more intense heat. Expect sunny skies and a high near 102F. The heat index is projected to reach 104.

Winds will ease up, coming from the south southwest at 5 to 10 mph. There is no chance of rain tomorrow. Overnight into the early hours of the next day, conditions will be mostly clear with a low around 79F and heat index values remaining high at 104.

Safety Reminders

With heat indices exceeding 100F, it is critical to take precautions against heat-related illnesses. Stay hydrated by drinking water frequently, even if you do not feel thirsty. Limit outdoor exertion, especially during the midday hours when the sun is strongest.

Check on elderly neighbors and those who may be vulnerable to extreme heat. If you must go outside, wear lightweight, light-colored clothing and seek air-conditioned spaces whenever possible.
