RALEIGH, NC — Another hot and heavily humid day settled over North Carolina on Friday, the final day of the workweek, as highs climbed into the 90s and near 100 degrees across most of the state, pushing heat index values into the dangerous 100 to 110-degree range across Central and Eastern North Carolina under mostly sunny skies.
Statewide Heat Reaches Oppressive Levels
Temperatures Friday afternoon were forecast to soar well into the 90s for the vast majority of the state, with numerous cities flirting with or reaching the triple-digit mark. Raleigh, Fayetteville, and Sanford were each expected to top out at 100 degrees, while Durham, Rocky Mount, and Wilson climbed to 98 degrees, and Greensboro, Roxboro, and Halifax reached 97 degrees. Even the state’s cooler mountain communities were not spared the heat, with Asheville reaching 91 degrees and Boone hitting 85 degrees, considerably warmer than typical for higher elevations this time of year.
Why the Heat Index Matters More Than the Thermometer
While the actual air temperature across Central and Eastern North Carolina was forecast to reach the mid-to-upper 90s and low 100s, the combination of that heat with high humidity levels pushed the heat index, or what the temperature actually feels like to the human body, into a far more dangerous 100 to 110-degree range. This gap between the actual thermometer reading and the heat index is a critical distinction, since the heat index reflects the added strain that humidity places on the body’s ability to cool itself through evaporation, making prolonged outdoor exposure considerably more dangerous than the air temperature alone would suggest.
Cities across the eastern half of the state, including Wilmington, Jacksonville, New Bern, and Kinston, were among the areas expected to see the steepest heat index values, with humidity streaming in off the Atlantic compounding the effects of the afternoon heat. Health officials routinely caution that heat index values in this range pose a significant risk for heat exhaustion and heat stroke, particularly for anyone engaged in prolonged outdoor activity, young children, older adults, and individuals without reliable access to air conditioning.
Scattered Storms Expected Later in the Day
Beyond the oppressive heat, forecasters were also tracking the potential for scattered to isolated thunderstorms to develop later Friday afternoon and into the evening, generally beginning after 3 PM and continuing through the later afternoon and early evening hours. These storms were expected to develop from north to south across the state, with the potential for gusty winds and bursts of heavy rainfall at times as they move through.
Coverage of these storms was not expected to be particularly widespread, with forecasters noting that areas farther north in North Carolina carried a better chance of seeing storm activity compared to points farther south. Most of the storms that do develop were expected to weaken and fall apart after sunset, limiting the overall duration of any severe weather threat heading into the overnight hours.
Clouds Increase as the Day Progresses
Skies across the state were expected to start the day partly to mostly sunny before clouds gradually increased later in the afternoon, a typical pattern ahead of the scattered storm development. That increasing cloud cover, combined with the ongoing heat and humidity, created a textbook late-summer setup across North Carolina, with the atmosphere growing increasingly unstable as the afternoon progressed and daytime heating reached its peak…
