A front that recently moved off most of the Eastern Seaboard will continue to move out over the Atlantic Ocean with a trailing boundary lingering over Florida through Saturday evening. Tropical moisture south of the front and dynamics associated with the front will aid in producing showers and thunderstorms over the Florida Peninsula through Sunday. In addition, upper-level energy over the Northeast will move eastward into Southeastern Canada by late Friday night. The energy will aid in producing rain over parts of the Northeast ending overnight Friday. Meanwhile, low pressure over the Northern/Central Plains will move southeastward to the Middle Mississippi Valley by Saturday evening. The area of low pressure will aid in producing showers and thunderstorms over parts of the Upper/Middle Mississippi Valley into parts of the Central/Southern Plains that will move eastward into the Ohio Valley by Saturday morning and into parts of the Central Appalachians by Sunday. A front moving southward from Central Canada will move into the Upper Great Lakes/Upper Mississippi Valley by Friday evening and into the Great Lakes to parts of the Middle Mississippi Valley then into the Northern Plains by Saturday evening.

Additionally, diurnal heating will aid in producing showers and thunderstorm over the Northern/Central Rockies through Sunday.
