A cold front extending from the Northern Appalachians southwestward to the Western Gulf Coast will move off most of the East Coast by Friday evening. The system will produce showers and thunderstorms from parts of the Western Gulf Coast to the Southern Ohio Valley that will move eastward to Southeast by Friday morning and to the Southern tip of Florida by Friday evening. Moisture flowing northward from the Atlantic over the Mid-Atlantic will aid in producing showers and thunderstorms over parts of the Mid-Atlantic through Thursday afternoon. The storm will also produce light to moderate rain over parts of the Northern Ohio Valley into the Lower Great Lakes that will move to parts of Southern New England to the Southern Appalachians by Thursday evening, then off the East Coast by Friday afternoon. A secondary front over the Upper Great Lakes will move eastward to the Lower Great Lakes before dissipating by Friday morning. The energy associate with the boundary will produce snow over parts of the Upper Great Lakes that will move into parts of the Lower Great Lakes and Northern New England by Thursday evening into Friday morning. The western end of the front over the Northern Plains will break off and move southward to the Southern Plains by Friday evening. A small area of snow over the Northern Plains will move southeastward to the Central Plains changing over to rain by Thursday evening. In addition, upper-level energy flowing southeastward to Upper Mississippi Valley/Ohio Valley from West-Central Canada Thursday night into Friday will aid producing an area of light snow over parts of Northern Plains moving into parts of the Upper Mississippi Valley by Friday evening. Light rain will also develop over the southern parts of the area of precipitation on Friday morning moving southeastward to parts of the Central Plains/Middle Mississippi Valley by Friday evening. Elsewhere, a front moving onshore over the Pacific Northwest will aid in producing light to moderate rain along the Northwest Coast and rain inland by Friday evening.
