Winter storm warning and advisory areas remain the same, refer to my previous post for that information.

-Rain continues to fall as of mid-evening with temperatures holding in the mid/upper 30s with dew points generally in the 34-38 degree range as of 9 PM.

-Stronger forcing associated with the low over North Central Illinois will arrive from SE-NW late tonight and Wednesday; As this occurs will see dynamical cooling processes take place which should cause the rain to switch over to snow.
