Accumulating snow and dangerous cold will highlight the remainder of the week. Make sure you are plugged into the forecast for all of the latest updates, and consider taking precautionary measures now. #ILwx
A clipper system will bring light to moderate snow accumulations to portions of central Illinois later Thursday afternoon through early Friday morning. Accumulations are expected to be the greatest along a line centered from Galesburg to Paris.
Very cold temperatures will spill in from the north this weekend. The feel-like temperature will fall well below zero, especially Saturday night. Frostbite and hypothermia will be a concern for vulnerable and at-risk populations. We recommend staying inside.
