Light to moderate freezing rain is possible on Wednesday across the Pacific Northwest. Moderate to heavy rainfall is likely across the Southeast; flooding is possible.
A wintry mix of light to moderate freezing rain and light snow will continue across the interior valleys of Washington and northern Oregon today before tapering off later this evening and into the overnight hours. Freezing rain will be the primary hazard with additional amounts of 0.05-0.15 inch possible. Some isolated locations could receive in excess of 0.25 inch. This may lead to hazardous travel conditions and perhaps power outages across the region.
A cold front is expected to drift slowly eastward across the southern Appalachians today with showers and isolated thunderstorms continuing along and ahead of the front. This will bring a continued threat of heavy rainfall across the region, mainly through the afternoon hours. Additional rainfall amounts of 0.25 to 0.75 inches, with locally heavier amounts in excess of an inch possible. Due to recent heavy rains, there will be an increased risk of flooding or flash flooding.
