*As of Aug 7, 4 AM local time.*
Very hot, humid start
Prosper is starting out clear and muggy, and the main weather story is the heat. The current air temperature is 81F, but it feels like 85F with relative humidity at 74% and a dew point of 72F. Wind is at 8 mph, with gusts up to 17 mph.
That moisture in the air will make the heat feel heavier as temperatures climb. Today is expected to be sunny, with a high near 100F and a low near 80F. The chance of precipitation is only 2%, so rain is not expected to provide much relief. Heat index values may reach as high as 103F.
Today, tonight and tomorrow
Today’s wind is expected from the south southwest at 5 to 10 mph. Skies stay sunny, and conditions remain very hot.
Tonight is expected to be mostly clear, with the low around 79F and temperatures rising to around 81F overnight. Heat index values may be as high as 101F, with south southeast wind around 10 mph.
Tomorrow brings more sun and more heat. The forecast high is near 99F, with a low near 78F and an 11% chance of precipitation. Heat index values may again reach as high as 103F, with south southwest wind at 5 to 10 mph.
