 cool and refreshing out the door tomorrow now tomorrow and wednesday a little warmer more seasonable highs in the upper 80s but humidity remains low and then for the fourth of july in true dc fashion the heat the humidity return will have highs in the lower 90s but heat index values late week in this weekend back to around 100 and we do have a chance for showers and storms on thursday for the fourth of july i do think most of that will happen during the afternoon and then starting to taper off by sunset and the sun sets this time of year just after 8 30 so
