Air quality alert leads the forecast

An Air Quality Alert is active for Prosper, and that is the main weather-related concern as hot, sunny weather continues. The alert comes from NWS/NOAA, and no other active weather alerts are listed in the provided forecast information.

Conditions are quiet right now during Tuesday overnight. Prosper is at 75F, with a feels-like temperature of 76F. Relative humidity is 74%, and the dew point is 66F. Wind is light at 3 mph, with gusts up to 13 mph, and the sky is clear.

Hot and sunny today, mostly clear tonight

Today is expected to be sunny, with a high near 99F and a low near 76F. The chance of precipitation is 2%, so rain is not a meaningful part of the forecast. Heat index values may reach 100F, and south wind is expected at 5 to 10 mph.

Tonight stays mostly clear. The forecast includes a low around 79F, with temperatures rising to around 81F overnight. Heat index values may be as high as 99F, with south southeast wind around 10 mph.

Tomorrow is forecast to be sunny again, with a high near 100F and a low near 80F. The chance of precipitation is 1%. Heat index values may reach 102F, with south southwest wind at 5 to 10 mph.

With the air quality alert and high heat, keep outdoor activity reasonable, take breaks, and drink water. People sensitive to air quality or heat should pay attention to how they feel and adjust plans as needed.
