While most of the attention has been paid to the incredible snow making machine coming off Lake Ontario, the cold air that has been one of the factors in the Lake Effect showers, the cold air is going to be around through the week ahead.

Post-Thanksgiving travel plans were thrown into trouble as almost 30 inches of snow fell along Lake Erie, closing a stretch of I-90 and stranding motorists.

From Minnesota to Texas, temperatures were expected to drop by double-digits as cold air swept over the record-warm Great Lakes, bringing the season's first lake effect snowfall. Common in the winter in this region of the US and Canada, lake effect snow occurs when very cold air moves across the relatively warm water of the lakes.
