Rain is falling across the northeast on Thursday morning, setting up what's bound to be a soggy Thanksgiving for dozens of states.

Reduced visibility and heavy snow—up to 6 feet of snow accumulation in some parts—are forecast just days away from Thanksgiving. And the National Weather Service has issued warnings for 13 states: Colorado, California, Nevada, Utah, Wyoming, Vermont, Michigan, Alaska, New York, Idaho, Maine, New Hampshire and New Mexico.

When the San Francisco 49ers come to Orchard Park on Sunday night, they won’t be bringing the Northern California weather with them.  As with most lake effect systems, the exact location of the locally heavy snow bands can vary.
