Hurricane Nate will impact the Central/Eastern Gulf Coast and parts of the Southeast with heavy rain and tornadoes through Sunday evening. Showers and thunderstorms will move into the Tennessee/Southern Ohio Valleys and the Southern Appalachians overnight Sunday moving into the Central Appalachians by Monday morning. Nate is forecast to steadily weaken while moving northeastward from the Central/Eastern Gulf Coast, early Sunday to the Northern Mid-Atlantic by Monday evening. In addition, Nate will become a Post-Tropical-Cyclone as rain moves into parts of New England also by Monday evening. For the most current information on storm track and intensity of Nate see the latest advisory from the National Hurricane Center. Meanwhile, a front extending from the Lower Great Lakes/Northern Appalachians to the Central Appalachians/Tennessee Valley into the Lower Mississippi Valley/Southern Plains will be just to the north of Nate on Sunday. The western end of the boundary will dissipate on Sunday. On Monday the front will begin to dissipate as Nate becomes Post-Tropical. Showers and thunderstorms will develop along and near the boundary from parts of the Northeast to the Ohio Valley. The showers and thunderstorms will move off the Northeast Coast by Sunday evening. The showers and thunderstorms will continue over parts of the Ohio Valley into the Northern Mid-Atlantic through late Sunday evening. Rain will surge northward overnight Sunday into Monday over the Ohio Valley/Northern Appalachians lifting into Northern New England by Monday evening. Furthermore, in the wake of Nate, tropical moisture will continue over the Southeast into parts of the Southern Mid-Atlantic then surge northward over the Central/Eastern Gulf Coast into the Tennessee Valley on Monday. Weak upper-level impulses and diurnal heating will aid in producing showers and thunderstorms over the Lower Mississippi/Tennessee Valleys eastward to the Southeast/Southern Mid-Atlantic on Monday. In the meantime, a strong cold front over the Upper Great Lakes/Upper Mississippi Valley into the Central Plains then westward into the Central Rockies/Great Basin will advance eastward to the Lower Great Lakes/Ohio Valley and southward into the Middle Mississippi Valley/Southern Plains by Monday evening. The system will produce rain over parts of the Pacific Northwest Coast and snow at the higher elevations of the Cascades on Sunday morning ending by Sunday afternoon. Snow and lower elevation rain will also develop over parts of the Northern Intermountain Region/Northern Rockies on Sunday. The snow and lower elevation rain will begin to move into the Central Rockies by Sunday evening continuing over the Central Rockies and into parts of the Southern Rockies on Monday into Monday evening. Rain will also develop over parts of the Central High Plains/Central Plains on Monday, too. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
