Took a while for the steadier snow to reach Duluth today, but it finally did late this afternoon, and it should continue to snow through the evening before tapering off later tonight. This won’t be a blockbuster snowstorm in Duluth (never was suppose to be) but there should be enough snow to cause some travel issues tonight into Tuesday morning especially with the colder temperatures that have moved in which has led to wet/slushy roads refreezing, then you throw in a few inches of fluffy snow tonight and you have the makings for some tricky travel conditions with snow/ice covered roads.
