A fast-moving storm sweeping across the U.S. at the start of the week won’t post too much of a threat, although some snow could lead to delays on the ground and in the air across the Great Lakes region while rain could lead to delays in the Northeast.

The Midwest and Great Lakes regions will see rain and snow Monday and the East Coast will be the most impacted on Thanksgiving and Black Friday, forecasters said.

Forecasters have warned of another round of winter weather that could complicate travel around the Thanksgiving holiday.
