Current Conditions and Heat Index

It is currently Sunday afternoon in Richardson, TX, and the heat is already intense. The air temperature stands at 88F, but the combination of heat and moisture makes it feel significantly warmer. The current feels-like temperature is 96F, driven by a relative humidity of 62% and a dew point of 73F.

These conditions create a muggy atmosphere that can make outdoor activities feel more strenuous than the actual temperature suggests.

The sky is mostly cloudy at this moment, but the heat is the primary concern for locals. Winds are blowing from the south at 13 mph, with gusts reaching up to 23 mph. This breeze offers little relief from the oppressive heat index values that are expected to rise further throughout the day.

Forecast for Today and Tomorrow

The National Weather Service indicates that today will be sunny with a high near 94F. Temperatures are expected to fall slightly to around 92F in the afternoon, but the heat index will climb as high as 102. South winds will continue around 15 mph, with gusts as high as 25 mph.

The chance of precipitation today is only 4%, so rain is not expected to provide any cooling relief.

Tonight, skies will become partly cloudy with a low around 79F. The heat index will remain high, reaching values as high as 103. South winds will persist at 10 to 15 mph, with gusts up to 25 mph. There are no active National Weather Service or NOAA weather alerts in effect for Richardson.

Tomorrow, the heat will continue with a high near 95F. The heat index is forecast to reach 103. There is a slight chance of showers and thunderstorms between 7am and 4pm, with a 20% chance of precipitation.

Skies will be partly sunny. South winds will remain steady at 10 to 15 mph, with gusts up to 25 mph. Residents should stay hydrated and limit midday exertion during this period of extreme heat.
