Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 343 PM EDT Sun Oct 08 2017 Valid 00Z Mon Oct 09 2017 - 00Z Wed Oct 11 2017 ...Tropical Depression Nate will bring heavy rainfall from the Southeast to New England... ...Moderate to heavy snow over parts of the Central Rockies... As Nate moves on its northeast path across the Tennessee Valley and into the Mid-Atlantic, it will continue weakening while bringing heavy rain to much of the eastern U.S. The center of Nate will move away from the Tennessee Valley overnight and quickly progresses toward the central Appalachians. Therefore, the axis of heavy rainfall through tomorrow morning will occur in parts of the Ohio Valley, along the southern Appalachians, and in the Southeast. Some bands will also bring heavy rainfall to parts of the Florida Panhandle. The greatest threat of flash flooding will occur in the southern Appalachian mountains--specifically a moderate risk in northern Georgia through western North Carolina. As the remnants of Nate move across the Northeast on Tuesday, scattered showers will move occur in both the Northeast and New England with a marginal chance of flash flooding. As another front begins to approach the Southeast, additional showers and thunderstorms can be expected across the Tennessee Valley, Southeast and lower Mississippi Valley on Tuesday. Heavy rainfall will also occur along the surface front in the middle Mississippi Valley by Tuesday evening as the surface low lifts into that area. As an upper level trough digs across the Central Rockies, a surface cold front will sweep across the western U.S. while bringing much colder conditions with it. With the right ingredients in place, a burst of heavy snow across the Central Rockies can be expected throughout Monday. Thus, winter storm warnings and advisories are in place across Colorado and southeast Wyoming. As the upper level trough swiftly moves over the Plains by Tuesday morning, the precipitation along the Rockies will come to an end.
