Very hot weather is the main story

Prosper is starting out clear and warm, and the bigger concern is the heat building today. The current air temperature is 77F, with it feeling like 78F. Relative humidity is 74%, and the dew point is 68F, giving the air a muggy feel even before the day heats up.

Wind is light at 5 mph, with gusts to 14 mph, and the sky is clear. Those conditions set up a sunny and very hot day ahead, with the forecast high near 102F. Heat index values may climb as high as 105.

Today, tonight and tomorrow

Today is expected to stay sunny, with only a 3% chance of precipitation. South southwest wind is forecast at 5 to 10 mph. The low for today is near 79F.

Tonight should be mostly clear, with a low around 81F. Heat index values could still be as high as 105, and south southeast wind is expected around 10 mph.

Tomorrow brings more sun and more heat. The forecast high is near 100F, with a low near 79F and a 2% chance of precipitation. Heat index values may again reach as high as 105, with south southwest wind around 10 mph.

Alerts and heat safety

There are no active NWS/NOAA weather alerts for Prosper.

Even without an alert, this level of heat can be hard on the body. Drink water, take breaks from outdoor exertion, and spend time in shade or air conditioning when possible. Check on people and pets who may be more vulnerable to heat, and avoid leaving anyone in a parked vehicle.
