Powerful Pacific Storm to Continue Impacting Northern California; Heavy Snow in the Appalachians and Portions of the Northeast

Unsettled weather is expected across much of the Northeast and Great Lakes over the next few days, including the likelihood of heavy snow in the central Appalachians and higher elevations of northeastern Pennsylvania and southern New York.

Overview

A strong upper-level wave pivoted across the Upper Peninsula on Friday bringing widespread snow, with significant lake enhanced snow off of Lake Superior and Lake Michigan. Initially, the heavier lake enhanced snow was confined to areas north of Lake Michigan on Friday, then as a surface trough pushed south across the Upper Peninsula, heavy lake enhanced snow pushed across western Upper Michigan late in the day Friday, and then shifted over north central portions of Upper Michigan late Friday night into Saturday morning. As these heavier bands of snow pushed onshore late in the day Friday through Friday night, whiteout conditions were reported. Also behind the system, sporadic power outages and blowing/drifting snow occurred as wind gusted upward of 45 to 55 mph, especially over the Keweenaw Peninsula. Near the Lake Superior shoreline across western and north central Upper Michigan, high-end gales of 40 to 45 knots brought waves of 14-18 feet and concerns for minor lakeshore flooding and beach erosion Friday night through Saturday morning.
