Posted: Jul 5, 2026 / 07:21 AM EDT Updated: Jul 5, 2026 / 07:29 AM EDT Sunday will bring another day of dangerous heat across central North Carolina, with afternoon highs around 102 degrees. When combined with the humidity, heat index values will once again climb into the 105 to 110 degree range, making prolonged time outdoors hazardous. The same strong dome of high pressure responsible for the holiday weekend heat remains firmly in place, keeping skies mostly sunny and rain chances very limited.
