The sky is expected to clear for a time this evening which may lead to the formation of fog, especially over the snow covered areas of west central through east central Illinois. Low temperatures should be within a few degrees of 30 by Saturday morning.
A couple of weak weather systems will bring periodic chances for light rain and snow to central, east central and southeast Illinois this weekend. At this time, it appears most of the significant snow accumulations are expected to remain to our north. The first wave of rain and snow will arrive tomorrow morning across the north and slowly spread to the south with mostly a rain chance for central and southeast Illinois later in the day. The second round of light precipitation is expected Saturday night into Sunday, but snow and rain amounts with that weather system will also be light. Our overall snow totals across central Illinois will be mainly less than one inch, mostly along and north of a Springfield to Champaign line.
