The Chicago area will see a unique confluence of events Thursday night and Friday morning, with the coldest temperatures of the season coinciding with an almost total lunar eclipse during the night.
Low temperatures are expected to reach the mid-20s, but that will play a secondary role to the show playing in the sky over the Chicago area, with a lunar eclipse, with 95% coverage, occurring immediately after 3 p.m.
Unfortunately for some area residents, cloud cover could conspire to damage the show. Those clouds could obscure the eclipse in some places, but areas in the south and west of Chicago might be able to see a clearer sky when the eclipse occurs, starting around 1 a.m. and ending just after 4 p.m.
Friday should be mostly dry in the area, but snowfall is expected to arrive late in the evening. High temperatures are expected to be cool again, struggling to reach 40 degrees, with precipitation arriving with a new weather system in the evening hours.
Saturday and Sunday are likely to see rain and snow showers occasionally, especially in the morning and evening hours, but high temperatures will rise to the upper 40s or low-50s in most places.
Monday will see much colder temperatures struggling to reach the freezing mark, and will also see lake-effect snow showers in northwest Indiana, according to extended forecast models.
