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. ...more to follow... A powerful cold front will push across the West over the next several days bringing the potential for the first significant snowfall of the season to Denver and Cheyenne. The cold front is already pushing through the intermountain West with showers and falling temperatures taking hold across the Pacific Northwest. Snow is expected across much of the higher elevations of the Pacific Northwest and central and northern Rockies. Once the front has pushed southeastward into southern Plains temperatures along the central high Plains will be as much as 30 degrees below normal. Winter storm watches are in effect for parts of northern Colorado and southern Wyoming. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
