Heat index soars above 100 degrees as Washington confronts summer's hottest day

Vernon: Better rain chances this weekend

Temperatures will climb near 90 by noon, and eventually into the low 90s. Models continue to trend with less in the way of 90s and triple digit heat, and more 80s and 90s, along with chances for showers and storms.

In a hazardous weather outlook issued for Wednesday, the Weather Service predicts it will feel like somewhere between 100 and 104 degrees each afternoon Wednesday through Friday in central North Carolina. This weekend though, the coverage looks higher and that's poor timing for SlossFest.

"We're looking at a cold front moving through from the northwest for the weekend, which will knock high temperatures down into the mid-80s". Sunday will also feature abundant sunshine, manageable humidity, and warm temperatures.

There is some good news, as temperatures next week are not going to be as hot.
