Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 259 PM EST Fri Jan 10 2025 Valid 00Z Sat Jan 11 2025 - 00Z Mon Jan 13 2025 ...A significant southern winter storm will wrap up tonight into Saturday morning as it slides off the Mid-Atlantic Coast... ...Pacific Storm to bring widespread snows as it races across the northern Great Basin and the northern Plains into the Upper Midwest and Upper Great Lakes this weekend... The significant winter storm that brought widespread impacts to much of the South over the past couple of days will wrap up tonight into Saturday morning as the associated low pressure system quickly sweeps eastward off the Mid-Atlantic Coast. Prior to its exit, widespread light to moderate snow will fall from the Tennessee Valley to the Mid-Atlantic. The highest snowfall accumulations will be confined to the higher elevations of the central and southern Appalachians as well as southern Virginia where an overall 3 to 6 inches (with locally higher amounts) is expected. Lighter snows will extend northward into the Ohio Valley and parts of the Northeast which will result in roughly 1 to 3 inches of accumulation. To the south of the heaviest swath of snow, freezing rain and disruptive icing will be a concern across portions of the Carolinas, particularly for the Charlotte and Raleigh metro areas where a tenth to three tenths of an inch of ice is expected. The widespread footprint of both snow and ice combined will lead to additional impacts, including dangerous travel conditions and power outages. Most locations will start to dry out by Saturday afternoon in the wake of the storm, but temperatures will plummet by as much as 10 to 20 degrees below normal through the remainder of the weekend. A fast-moving Pacific storm has pushed into the Pacific Northwest, which brought coastal rains and mountain snows to much of Washington and Oregon this morning and early afternoon. This system will quickly race across the northern Great Basin and into the northern Plains tonight into Saturday morning, producing widespread snows as it does so. The most significant accumulations will occur in the highest elevations of the northern and central Rockies where accumulations in excess of 1 to 2 feet are likely. The storm will scoot across the northern Plains and into the Upper Midwest by Sunday, bringing widespread lighter snows to those regions with a general 1 to 4 inches of accumulation.
