Rain continues to push through the bi-state region Saturday morning, with temperatures at or just above freezing. Temperatures will hold steady through the day, with rain moving out by midday for the majority of the area until the next wave moves in after midnight Sunday morning.
An Ice Storm Warning is in effect through midday Sunday for just about the entire viewing area. Additional ice accumulation will be around 1/10" today and early Sunday.
Main routes will likely be in good shape if they continue to be treated, but some slick and slushy spots will be possible. Untreated roads and elevated surfaces will likely have the most ice accumulation.
Winds will remain light, so widespread power outages will likely not be an issue.
