You’ll notice a difference today. A hot day, but much drier than yesterday, and with a nice breeze from the west. But humidity will be back Sunday and Monday as we remain on the northeastern edge of a major heatwave and disturbances riding along it play with the “humidity switch”. By Tuesday, expect to be back into some drier air again, and a little less heat, lasting through midweek and including Independence Day. Disturbances are most likely to cause shower and thunderstorm threats early Sunday morning and during the day Monday, based on current timing.
