Current Conditions and Heat

It is currently Thursday this afternoon in Frisco, where the air temperature sits at 90F. However, the combination of high moisture and warmth means the heat index feels like 98F. Relative humidity is at 59%, and the dew point is 73F, contributing to a noticeably muggy atmosphere.

The sky is mostly cloudy, and winds are blowing from the south southeast at 14 mph, with gusts reaching 25 mph. These conditions create a sticky environment that can make outdoor activities feel more strenuous than the actual air temperature suggests.

Today and Tonight Outlook

For the rest of today, there is a 32% chance of showers and thunderstorms. The high will be near 91F, though temperatures may fall to around 89F in the afternoon. Heat index values are expected to reach as high as 103F.

Tonight, the chance of precipitation remains at 30%, with partly cloudy skies. The low temperature will be around 75F, but it may rise to 77F overnight. Winds will continue to blow from the south southeast at 10 to 15 mph, with gusts up to 25 mph.

Rainfall amounts, if they occur, are expected to be less than a tenth of an inch.

Tomorrow and Safety

Tomorrow brings a slight chance of rain showers before 7am, followed by mostly sunny skies. The high temperature will climb to near 95F, with a low of 77F. The heat index could reach 106F, making it feel even hotter than the actual temperature.

Winds will be lighter, coming from the south at 5 to 10 mph. The chance of precipitation is 16%. Given the high heat index and humidity, it is important to stay hydrated and limit midday exertion.

Check on neighbors who may be vulnerable to the heat, and ensure you have access to cool, shaded areas or air conditioning when possible. There are no active weather alerts in effect for the area.
