St. Louis, MO – The National Weather Service in St. Louis has issued another Frost Advisory from 1 a.m. to 9 a.m. Friday, warning residents across central and southwestern Illinois of another cold morning ahead.
The advisory affects Greene, Macoupin, Montgomery, Fayette, Marion, Brown, and Pike Counties, including cities such as Centralia, Vandalia, Pittsfield, Salem, Mount Sterling, and Litchfield.
According to the NWS, temperatures are expected to dip to between 33°F and 34°F, cold enough to form frost on exposed surfaces. A previous Frost Advisory remains in effect through 9 a.m. Thursday, with Friday morning’s frost marking the second consecutive day of cold overnight lows.
