Thanksgiving Lake Effect Snow and Winds

High impact lake effect snow event expected this evening through Friday. Snow amounts of 6” to 12” are likely in typical NW snow belts and areas near and south of Grand Traverse Bay. Read More >

Any lingering rain will transition to snow tonight as temperatures fall near or below freezing, allowing snow to begin accumulating. A wider burst of snow this evening will transition to NW flow lake effect bands overnight, focusing the worst conditions across parts of the eastern UP and NW Lower MI. Expect low visibility, including whiteouts at times on exposed roadways, leading to potentially dangerous travel. By Thanksgiving morning, some folks will wake up to close to 6 inches of snow; though gusty winds overnight will make it difficult to measure accurately.
Intense NW flow lake effect snow bands will develop through the morning and last through the afternoon. These will lead to rapid changes in visibility and road conditions in and out of snowbands, from quiet conditions to near-zero visibility and snow covered roads beneath the worst snowbands. These intense snowbands will likely impact the US-131 corridor between Elmira and Fife Lake, and I-75 between Waters (exit 270) and at least West Branch. Gusty winds will lead to blowing snow as well. Lake effect snow will continue into Friday, though this is not expected to be as intense.
Another storm system crossing the central US this weekend could bring a second round of snowfall to our region starting as early as Saturday afternoon/evening. Track and timing of the system are still up in the air, so stay tuned for additional details as they become clearer.
