A LAKE EFFECT SNOW WARNING REMAINS IN EFFECT
A band of heavy snow will lift north into portions of Southern and Central Lewis County, Southern Jefferson County, Northern Oswego County, Northern Herkimer County and Northern Hamilton County, late this afternoon and remain nearly stationary overnight and Thursday morning before dropping south again in the afternoon. Snowfall rates will reach 4 to 5 inches per hour under the most intense portion of the band. Additional accumulations of 2 to 3 feet are likely over portions of the Tug Hill tonight…with 12 to 18 inches possible in portions of the Black River Valley and Western Adirondacks.
Additional accumulations of 1 to 2 feet are likely over the Southern sections of Jefferson County with 3 feet possible along the Oswego County line. Additional accumulations tonight will reach 2 to 3 feet in the most persistent bands over the Northern sections of Oswego County, with more snow expected Thursday. Total snow accumulations of 7 to 15 inches are expected in the most persistent areas of snow across Northern Herkimer County. 5 to 10 inches of snow is expected in Hamilton County. The snow should be at its heaviest Thursday morning. With areas along or North of Route 28 and West of Route 30 receiving the greatest snowfall. This will bring storm totals for the week to 100 inches or more in some locations.
In addition to the extreme snowfall amounts, strong winds will create near blizzard conditions at times, especially near the edges of the Lake Effect Snow Bands where winds are typically stronger than under the center of the band. The gusty west winds will cause blowing and drifting of the snow. Travel will be extremely difficult or even impossible at times through Thursday evening, especially on North/South roads such as interstate 81.
A Lake Effect Snow Warning means significant amounts of lake effect snow are forecast. This will make travel very hazardous or impossible. Lake-Effect Snow showers typically align themselves in bands and will likely be intense enough to drop 1 to several inches of snow per hour for several hours. Visibilities vary greatly and can drop to zero within minues. Travel is strongly discouraged. Commerce could be severely impacted. If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.
