Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 247 AM EST Mon Dec 10 2018 Valid 12Z Mon Dec 10 2018 - 12Z Wed Dec 12 2018 ...Major winter storm abating across the Mid-Atlantic region and rain/mountain snow returns to Pacific Northwest... The winter storm that has been hammering the interior southeast U.S. and parts of the Mid-Atlantic region this past weekend is now moving offshore, after producing one to two feet of snow across northwest North Carolina and south-central Virginia. However, some lighter mixed wintry precipitation is expected to linger across parts of these same areas on Monday as an upper level disturbance passes through the region, and leads to a secondary surface low off the Mid-Atlantic coast. Travel conditions remain hazardous for many of these areas affected, and additional power disruptions are possible. Across the western U.S., a Pacific cold front making its way inland is expected to produce snow showers from the Sierra Nevada to the northern Rockies through Monday night. A second storm system approaching the Pacific Northwest on Tuesday will likely produce heavier precipitation from western Washington to Idaho, with heavy snow for the Cascades and a couple inches of rainfall and gusty winds near the coast. Much of the central U.S. should be void of any significant precipitation for the beginning of the work week as a large surface high continues to govern the weather pattern. This also holds true for the Desert Southwest and the Ohio Valley region. Temperatures are expected to be below normal across much of the central and eastern U.S. on Monday, and then some moderation by Tuesday. The warmest readings will continue for the southwestern U.S. through early Wednesday. D. Hamrick Graphics available at
