Hurricane Nate will impact the central Gulf Coast with storms surge, strong winds, heavy rain, and tornadoes this evening. Nate's outer bands are already coming ashore across the central Gulf Coast and conditions will deteriorate this evening as the storm makes landfall overnight. Heavy rainfall will push inland tomorrow and tropical moisture will interact with a cold front to the north to expand the area of heavy precipitation into the Ohio Valley. On Monday Nate will push into the central Appalachians while accelerating to the northeast. The interaction between the tropical moisture and the higher terrain of the central and southern Appalachians will focus heavy rainfall over the area. Flash flooding is likely along the track of Nate. A moderate risk of excessive rainfall has been issued for the central Gulf Coast through Sunday morning and for the southern Appalachians through Monday morning. 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. Krekeler Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
