Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 AM EST Sat Feb 04 2017 Valid 12Z Sat Feb 04 2017 - 12Z Mon Feb 06 2017 ...Heavy snow possible for portions of the Tetons, Wind River Mountains, Absarokas, and Bitterroots... ...Heavy rain possible for Northwest Coast, including Northern California, Washington, and Oregon... ...Snow possible for the Great Lakes region through Sunday, then transitioning to New England to close out the weekend... An upper-level low over the Eastern Pacific will continue to slowly weaken and move onshore over the Pacific Northwest. A plume of moisture will stream into California and across much of the Northwest through the weekend and into the first part of next week, resulting in rain along the coast, and a wintry mix of rain and snow along the higher terrain further inland. The Rocky Mountains and ranges from Idaho to northwest Wyoming can expect mainly snow, possibly heavy at times, over the next few days. A secondary low will travel eastward across the northern plains today. As it approaches the Upper Great Lakes, there will be a good potential for snow across this area starting this afternoon and continuing overnight. Snow, possibly with a mix of rain and freezing rain, is forecast for the central and northern portions of the Appalachians by early Sunday morning. The low pressure system will continue to travel eastward, with snow expected to spread into upper New England Sunday and Sunday night. For the rest of the U.S., high pressure will remain in control today. Strong southerly flow on the backside of the high pressure may bring moisture and rain chances across states bordering the Gulf Coast, starting with Texas today, and then transitioning eastward through the rest of the weekend as high pressure begins to exit off the Atlantic coast.
