Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 PM EDT Thu Nov 02 2017 Valid 00Z Fri Nov 03 2017 - 00Z Sun Nov 05 2017 ...Active weather pattern to take hold across the Pacific Northwest and northern Rockies with heavy mountain snowfall and valley rain... ...Warmer temperatures are expected for the southern and eastern United States over the next couple of days... The main theme over the next couple of days will be a transition to unsettled and stormy weather across much of the Pacific Northwest, the northern Rockies and parts of the northern Plains. Low pressure and associated cold front coming ashore in the Pacific Northwest today will push through the Intermountain West and Northern Rockies over the weekend. Falling temperatures behind the front combining with strong dynamics aloft will lead to heavy snowfall across the higher elevations. Winter storm watches, warnings, and advisories are in effect across the Cascades and northern Sierras as well as the northern Rockies. As the cold front slides southeast moderate to heavy rainfall is expected, especially into northern California. A cold front will continue to push across the Great Lakes and through the Northeast by Saturday. Only light to moderate precipitation is expected along the front with little available moisture. Modest southwesterly flow ahead of the front will allow warmer temperatures to build across much of the eastern U.S. before the frontal boundary arrives late Friday. Further southwest the cold front will stall across the Ohio and Tennessee Valleys with above normal temperatures expected across the southern Plains and Southeast.
