Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 257 PM EST Sun Dec 06 2015 Valid 00Z Mon Dec 07 2015 - 00Z Wed Dec 09 2015 ...Heavy rain expected to continue for the coastal Pacific Northwest through the next couple days... ...Heavy snow possible at the higher elevations of the Pacific Northwest and northern Intermountain states... ...High winds possible along the Pacific Northwest coast and across portions of the northern Rockies... An onslaught of Pacific low pressure systems will continue to impact the Northwest through the short range forecast period. Multiple systems will move into the region in such rapid succession that it will be difficult to distinguish where one ends and the next begins in terms of sensible weather impacts. A plume of Pacific moisture will bring widespread rain into the region, with snow for the higher elevations of the Cascades. Snow will also become more widespread farther inland in the Sawtooth, Bitterroot, and Teton ranges on Monday. The long duration of the precipitation will result in very heavy rain and snowfall amounts. Through Tuesday, rainfall amounts of 3 to 10 inches, with locally higher amounts, are forecast to occur across the coastal Pacific Northwest. Across the Cascades, heavy snowfall amounts of 10 to 20 inches, with higher amounts at the peaks, will be possible during this same time period. Additionally, high winds are forecast along the coast of Washington and Oregon, with winds of 30 to 40 mph, and gusts to 60 mph. Beaches and headlands will see the strongest winds, possibly gusting as high as 75 mph. Wind gusts as high as 60 mph are also possible from late tonight into Monday across portions of the Cascades. Please refer to forecasts and statements issued by local NWS forecast offices for details specific to local areas. Farther inland, snowfall amounts of 6 to 12 inches will fall across much of the Sawtooths, Bitterroots, and Tetons. Snow will be the most widespread across these areas on Monday, and will become more scattered into Tuesday. Strong, gusty winds will also be possible late Monday into Tuesday across portions of Montana and Wyoming. A stationary frontal boundary will keep showers in the picture for southern Florida through the next couple days. An area of low pressure will develop along a surface front off the southeast U.S. coastline on Monday, bringing showers to eastern portions of the Carolinas and possibly portions of southern Mid-Atlantic region before the system moves out to sea Monday night.
