Current Conditions and Alert Status

A Heat Advisory is currently in effect for the Frisco area, issued by the National Weather Service. This moderate-severity alert remains active until tomorrow evening. Right now, the air temperature stands at 95F, but the combination of heat and humidity makes it feel like 98F.

The sky is mostly clear, and the relative humidity is 39% with a dew point of 66F. Winds are blowing from the south at 7 mph, with gusts reaching 14 mph. These conditions contribute to the significant heat index values expected throughout the day.

Today and Tonight Outlook

Residents should expect sunny skies for the remainder of today, with the high temperature climbing near 100F. The chance of precipitation is 0%, ensuring dry conditions. As evening approaches, temperatures will drop to a low near 81F, though they may rise slightly to around 83F overnight.

The sky will remain clear tonight. Heat index values could reach as high as 107F during the day and 104F in the evening. Winds will shift to a south-southeast direction, averaging around 10 mph with gusts up to 20 mph.

The lack of rain and the persistent warmth mean the heat will linger well into the night.

Tomorrow's Forecast and Safety

Tomorrow will mirror today’s pattern, featuring sunny skies and a high near 100F. The low will be around 80F, potentially rising to 82F overnight. The chance of precipitation is minimal at 3%.

Winds will be lighter, ranging from 5 to 10 mph from the south. Heat index values are expected to peak at 107F again. Given the sustained high temperatures and low humidity, it is crucial to stay hydrated and limit strenuous outdoor activities during the hottest parts of the day.

Check on elderly neighbors or those without air conditioning, as the heat index can pose serious health risks. Stay indoors when possible and use air conditioning to maintain a safe environment.
