.DISCUSSION...
A passing weak cold front will bring an end to the near-record
heat, gradually recovering relative humidity levels. Due to
mostly dry soils, fog potential remains minimal overall,
restricted primarily to brief, localized morning fog along low-
lying river valleys and anywhere that receives rainfall from the
frontal passage.
