Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 159 PM EST Sun Dec 09 2018 Valid 00Z Mon Dec 10 2018 - 00Z Wed Dec 12 2018 ...Major winter storm to continue, especially across portions of the North Carolina and Virginia, expect near-impossible travel conditions and numerous power outages... A strong storm system off the Southeast U.S. coast will result in a high impact winter storm from extreme northeast Georgia and northwest South Carolina to central/southern Virginia. Winter storm warnings are in effect from northeast Georgia to central Virginia. Substantial snowfall accumulations are likely across the Southern Appalachians and the adjacent Piedmont of North Carolina and south-central Virginia, with some accumulations in excess of a foot possible through Sunday night where the best low-mid level forcing becomes established. Travel will be severely affected across much of these areas, and some power outages are likely. Mixed precipitation and wet snow to the south and east of the heaviest snowfall axis across the coastal plain of the Carolinas and southern Virginia will tend to lower overall accumulations there, but may still disrupt travel. Elsewhere, a front moving onshore over the Northwest will move inland to the Northern Plains to the Great Basin/Southwest by Tuesday. The system will produce heavy showers and mountain snow across the Pacific Northwest with snow moving into the Northern Intermountain Region by Monday afternoon and parts of the Northern/Central Rockies by Tuesday.
