Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 357 AM EDT Wed Nov 02 2016 Valid 12Z Wed Nov 02 2016 - 12Z Fri Nov 04 2016 ...Unsettled weather to continue across the Pacific Northwest... ...Heavy rainfall possible in parts of the Southern Rockies and New England today... ...Unusual warm weather expected across the eastern half of the U.S. for the next few days... Much of the Pacific Northwest Coast will remain unsettled through the week as a series of upper level disturbances cross the region. Showers and moderate rainfall is being observed along the British Columbia and Washington Coast as a front approaches from the Pacific. Another front will approach the region, resulting in additional rainfall to the Coast and areas inland as it moves onshore. The majority of the heavy rainfall, and higher elevation snow, will mostly be confined to British Columbia. However, the Olympics could have 3-day amounts nearing 3 inches. An expansive frontal boundary from Quebec to Arizona will slowly track east over the next couple of days. Scattered to widespread showers and thunderstorms will develop along this boundary. As the front stalls along the Great Lakes and Mississippi Valley on this afternoon, rain will will initiate and spread across the southern Plains/Rockies. Conditions in favor of slow storm motion, and/or higher rainfall rates, may setup up across portions of the Arizona, New Mexico and Texas; which could increase the risk for flash flooding. 1 to 2 inches of rainfall will be possible today across the southern Plains - with 3-day totals of 2 to 3.5 inches for West Texas and Southeast New Mexico. The northern half of the front will pass through the Great Lakes, Northeast and the Mid-Atlantic. Widespread rain is forecast for much of the Great Lakes and Ohio/Tennessee valley today- and for the Northeast and Mid-Atlantic Thursday into Friday as the front pushes through the eastern third of the U.S. Prior to the frontal passage, warmer than normal temperatures will dominate the eastern half of the U.S. Many locations will have temperature over 20 degrees above normal through Thursday.
