Nothing like a complex winter storm to kick off Meteorological Winter (Dec 1st). This storm has so many moving parts, that it’s tough to forecast but fascinating to watch. The storm will be so large and powerful that Metro Detroit, which is not expected to have a direct hit, could still see 2” – 5” of snow or more.
Why is it So Strong?
Mainly because it is expected to merge or phase with other storms in the upper levels of the atmosphere. This alone will help an area of low pressure to strengthen but this storm will also receive additional enhancements. A brief merge of the polar and southern jet steam will not only cause the storm to strengthen and move quickly – but will also help it tilt negatively. This is another feature, which increases the overall power of the storm. Simply put, with so many things working together to strengthen the storm it is no wonder it’s expected to bring major travel disruptions to a third of the country.
As of Sunday morning 11/29/20 - the local impacts appear to be similar to an average Michigan snowstorm. Our early call is 2” – 5” of snow for most of Metro Detroit with a few locations possibly going above that. We’ve noticed a trend while tracking this storm and it's an eastward shift in the track. If this continues the totals will go down along with with its movement.
Winds always put the strength of these low pressures on full display and this one is no different. Winds could gusts up to 35 or 40 mph - especially if you're east of I-75.
Storm details will improve once the storm goes through its first phase later tonight.
