Thankfully the overall intensity of the snow is decreasing tonight.  Scattered snow showers will continue to move across southeastern Wisconsin into the Tuesday morning commute.

Additional accumulation will remain light and below an inch; however, with cold temperatures already in place, it won't take much for roads to become slick and hazardous.

Secondary untreated roads will continue to be a problem with an additional light snow; moreover, even the main interstates and highways are reporting slippery conditions.

Expect more snow showers to develop throughout the day on Tuesday.  An additional inch is possible by Tuesday evening!
