Light snow continues but will gradually taper through the early evening hours. Until then, light snow, at times mixed with some freezing drizzle will be possible as activity moves towards the south and east. Slick spots will be possible on any untreated and elevated surfaces, especially within any freezing drizzle, into this evening.
Monday, mostly cloudy skies will continue with highs round 30 degrees and light west winds. Another disturbance may bring a chance of snow to parts of Illinois Monday night, but these look to remain south of our area at this time. The next low chances for some light snow are Tuesday evening and overnight. It will be cooler this week in the areas where the snowpack is the greatest, with some moderation in temperatures expected Wednesday and Thursday.
