An arctic cold front is approaching the Plains and Midwest States Sunday night, bringing an extreme change in temperatures - igniting the lake-effect snow machine through Tuesday. The air-mass out ahead of this front is already below average, but now the temps will drop another 10° - 20° in some areas. Despite the cold, snow will steal the headlines to start the work week so we'll talk about that first.
How it Impacts Metro Detroit:
This snow storm will get started in the morning during the rush hour commute with snow showers going from moderate to heavy from 4 AM and 8 AM. Snow will continue into the afternoon and evening before tapering off by Monday night. Some locations will see more snow than others, therefore we have two Winter Weather Alerts in effect: A Winter Weather Advisory and a Winter Storm Warning.
St. Clair and Sanilac Counties will have the greatest opportunity for the heaviest snowfall - possibly reaching 6" - 8" or more. This is due to "lake effect snow squalls," which will develop as the storm pulls away from metro Detroit.
