Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 301 AM EST Mon Feb 06 2017 Valid 12Z Mon Feb 06 2017 - 12Z Wed Feb 08 2017 ...Heavy rain and mountain snow will continue across the West over the next few days.... ...A developing system will bring precipitation chances to much of the eastern U.S. heading into the workweek... ...Near record warmth possible through midweek across portions of the Southern Plains through the Mid Atlantic... An active weather pattern will continue across the western U.S. over the next few days, as a strong surface low pressure system makes its way across the Intermountain West. Widespread mountain snow will continue from the Cascades to the central and northern Rockies, and mountain ranges in between. Storm total snowfall amounts between one and two feet will be possible across the Sierra, Cascades, and Rockies through tonight. Snowfall amounts less than one foot are expected elsewhere in the lower elevation mountains of the Pacific and Intermountain Northwest. Winter storm watches and warnings remain in effect for these areas. The greatest rainfall amounts are expected from central California to coastal Washington, where 3 to locally 6 inches of storm total rainfall will be possible through this evening, especially over upslope regions. Another low pressure system is expected to eject eastward from the central Plains, strengthening as it combines with yet another low traveling across the north central U.S. by Tuesday. As this system pushes northeastward and continues to gain strength, expect rain and thunderstorms to develop northward from the central Gulf Coast to the Ohio Valley and southern peripheries of the Great Lakes regions. Snow and mixed precipitation can be expected on the northern periphery of this low from Minnesota to northern New England. As we gear up for this system, warm air will lift northward ahead of the surface low, bringing a warming trend for much of the East Coast to start out the work week. In fact, a few records may be matched or exceeded for both daily high temperatures as well as daily high minimum temperatures from the Southern Plains (Monday and Tuesday) to the East Coast (Wednesday).
