Some snow can even turn to showers as warmer air works north during the night. This is unusual for these kinds of system but since the low-pressure center is well to our south we get warm air later than usual.

Road conditions are rather good early on Monday but get progressively worse as the snow spreads northeast. Tuesday morning is when most of our snow is done, but it will take time for the snow to be cleared. Some sunshine in the middle of the day could help melt but colder air coming after the snow keeps the snow around for many.
