Things can change and they will have to because right now temp and Dp about 3F above last night same time
i really though IAD was a lock during this stretch
Any southerly component throws a wrench into DC area.we need wnw or more northerly. Dews were 28-30 this time last night and that’s doesn’t allow much evap chilling if this had been Canadian high moving in we would have had those 24/25 dews and IAD would have made it easy and maybe others.
