1) Rain from thunderstorms could be very heavy over the Laurels and south-central mountains Sunday morning and again later in the day. There is still potential for some heavy rain to fall over the Lower Susquehanna Valley and Ridge-and-Valley region.
2) High pressure yields a short dry window before more storms arrive in mid-week.
