The combination of lingering arctic air and two merging storms has the potential to spread a large swath of snow, wintry mix and slippery travel from the Midwest to the part of the South and Atlantic Coast at the end of the week.
As with many winter storms, it’s complicated.
The storm scenario continues to trend colder and farther south than indications to start this week.
How much snow falls depends on how quickly two storms come together. One storm is coming from western Canada (an Alberta Clipper), and the other is a storm from the southern United States.
