TS Leslie is coming to an Atlantic basin near you. Looks promising for mid/late next week. GFS has Leslie parking itself about 600 miles east of Vacapes for a day or two while a front plows through the NE/mid-Atlantic giving us off-shore winds.
The GFS will flop around like a fish out of water over the next few days, but it's had this general idea of an approaching tropical + fropa for the past couple of days.
