Low pressure with showers and thundershowers still on track for Tuesday.  Nothing like the flooding rains over the southeast the last few days but some spots to the west of DC could get 1/2- 1"+ rain and around DC 1/2" rain looks very likely.  By late tomorrow dry air pushes in and Wednesday will be delightful.  Briefly some northeast winds come back with clouds on Thursday but late into the week and the weekend everything looks great right now with sunshine and comfortable humidity.  Umbrellas tomorrow
