what is the longest heat wave on record for asheville north carolina

Asheville’s longest heat-wave stretch is commonly described in National Weather Service materials as a period of at least two or more consecutive days of abnormally hot, humid weather, but the exact “longest on record” span for Asheville is not stated in the sources I could verify here. The most recent local coverage says Asheville is facing a prolonged heat wave through the July Fourth weekend, with highs flirting with records set in 1970.

What’s verifiable

• Local forecasts say Asheville will see hot conditions lasting several days, with the hottest stretch running Wednesday through Friday and lingering through the holiday weekend.

• The record high for July 2 and July 3 in Asheville is 93 degrees, both set in 1970.

• A weather source for the Carolinas defines a heat wave as abnormally hot, unusually humid weather lasting two or more days.

Practical read

If you mean “the longest multi-day heat wave Asheville has ever had,” that would require a historical climate record or archived NWS event list that is not included in the available results. Based on what is available, the current event is at least a multi-day heat wave, but I can’t responsibly name it as the record-holder from these sources alone.

Quick note

A separate Asheville weather-history page indicates the city’s hottest air temperature on record was 100 degrees on August 21, 1983, but that is a temperature record, not a heat-wave duration record.

TL;DR: I can verify Asheville is in a several-day heat wave and that record highs from 1970 are being threatened, but I can’t confirm the single longest heat-wave duration on record from the sources available here.
