Meanwhile, GSO only reached 93 yesterday with similar dewpoints. A combination of elevation and cloud debris coming off the mountains has consistently kept high temps much more reasonable (and also at times set up a boundary for storm development)
The data backs up my theory. The average high temp in June was 3.2 degrees higher at Raleigh than at GSO (90.0 & 86.8), compared to the historical average having a gap of 1 degree (86.1 & 85.1)
