Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 321 AM EST Wed Feb 08 2017 Valid 12Z Wed Feb 08 2017 - 12Z Fri Feb 10 2017 ...Heavy rain and flooding possible over parts of the Pacific Northwest and Northern California... ...A wintry mix of snow, rain, and ice is also expected across inland portions of the Pacific Northwest... ...Heavy snow possible across the Colorado Rockies today... ...A potential for severe thunderstorms over the Eastern Gulf Coast today... ...Heavy snow will occur across portions of New England tonight and Thursday... Yet another strong low pressure system will move towards the Pacific Northwest over the next few days. This will bring another surge of moisture to much of the region, which has already been heavily impacted by heavy rains and high snow amounts. More heavy rain is expected across much of northern California and coastal regions of Washington and Oregon starting this afternoon. Rainfall amounts of 2 to 6 inches are expected in these regions. Furthermore, warmer temperatures will cause melting of large amounts of snow, which will lead to flooding concerns. Flood warnings and watches are in effect for much of northern California, Oregon, and even northern Nevada and southern Idaho. Along the northern periphery of this system, a wintry mix of snow, rain, and ice is expected, with Winter Storm Warnings and Watches stretching from Washington to western Montana. A continuation of the previous low pressure system to move through the Pacific Northwest will make its way into the Rockies today, bringing another round of heavy snow to this region. Locally, up to 2 feet of snow is expected through this evening in the highest terrain. An active pattern will also remain in place across the eastern U.S. A strong low pressure system will continue to push northeast of the Great Lakes Region and New England throughout the day, with a cold front expected to sweep through much of Southeast U.S. through tonight. A secondary low will develop along this front tonight, increasing the surge of moisture inland along the Atlantic Coast. Much of the southeast and Mid Atlantic will see heavy rains and thunderstorms today and tonight, with portions of the Eastern Gulf Coast currently under a Marginal to Slight Risk Area from the Storm Prediction Center. Behind the front, colder air will interact with the precipitation. Much of the Great Lakes region will see snow today, transitioning across the Northeast Thursday as the secondary system increases in strength. A transition zone between the rain and snow will result in a wintry mix of rain, snow and ice across portions of the northern Ohio Valley and northern Mid Atlantic Regions during this time. Meanwhile, a surge of warm air will encompass much of the Gulf Coast and Atlantic Coast ahead of the approaching cold front today. This could once again lead to many locations near the coast reaching or possibly even exceeding either record high minimum temperatures, or record high maximum temperatures for the 8th of February.
