Current Conditions and Active Alert

A Heat Advisory is currently in effect for the Frisco area, issued by the National Weather Service in Fort Worth. This moderate-severity alert is expected to remain active until this evening. As of this afternoon, the air temperature stands at 97F, but the combination of heat and humidity means it feels like 102F.

Relative humidity is at 39%, with a dew point of 68F. Winds are blowing from the south at 10 mph, with gusts reaching 16 mph. The sky remains clear, offering no relief from the intense solar radiation driving these high heat index values.

Today and Tonight Outlook

The forecast for the remainder of the day indicates sunny conditions with a high near 102F. Temperatures are expected to fall to around 100F in the afternoon, but heat index values will climb as high as 110F. The chance of precipitation is minimal at 4%.

Tonight, the sky will be mostly clear with a low around 81F. However, temperatures are projected to rise to around 83F overnight, keeping heat index values near 107F. Winds will shift to the south-southeast at approximately 10 mph.

The lack of significant cloud cover means the ground will continue to radiate heat, preventing a significant drop in perceived temperature.

Tomorrow and Safety Reminders

Tomorrow will bring similar conditions, with sunny skies and a high near 102F. Temperatures will again dip to around 100F in the afternoon, with heat index values reaching 105F. The chance of rain is slightly higher at 7%, but precipitation is unlikely to provide substantial relief.

Winds will remain from the south at 10 mph. Given the sustained high heat index values across today and tomorrow, it is crucial to take standard safety precautions. Residents should hydrate frequently, limit outdoor exertion during the hottest parts of the day, and check on vulnerable neighbors.

Avoid leaving pets or children in parked vehicles, as temperatures can rise rapidly in enclosed spaces. Stay informed of any updates from local authorities regarding the ongoing heat advisory.
