Lower humidity then sets up a very pleasant Friday and Saturday, before Sunday edges a bit more humid again. Today (Tuesday): Sunny, hot and moderately humid with afternoon highs again into the mid-90s range. The morning remains rather muggy with dew points up near 70, perhaps becoming a little less humid in the afternoon with dew points dropping into the mid-60s.
