With 4 to 8 inches of lake effect snow on the way, the National Weather Service has issued a winter weather advisory for Jefferson and Lewis counties.
The advisory kicks in at 4 p.m. Monday and expires at 6 p.m. on Tuesday.
That 4 to 8 inches is for the hardest-hit areas, expected to be mostly on the Tug Hill.
That doesn't mean it won't drift north, though.
It will start out unorganized, so much of both counties could get some snow. Then it become more organized and settle south over the Tug Hill, likely by sometime Tuesday morning.
Outside the lake effect, it will be sunny and cold on Monday, with highs in the teens.
There will be clouds early Tuesday, then it becomes sunny as highs climb into the mid- to upper-20s.
There's a chance of snow each day Wednesday through Sunday. Highs will be in the low- to mid-20s through the workweek and in the low-30s on the weekend.
