Though temperatures Sunday are expected to climb into the low-40s, there is still the possibility of some freezing fog early in the day.
According to the National Weather Service, patches of freezing fog are possible in parts of eastern Illinois and northwest Indiana into the late morning hours Sunday, posing serious concerns for motorists in the impacted areas.
Officials say that fog could impact communities in Kankakee and Will counties, as well as Lake, Porter, Newton and Jasper counties in Indiana.
Patches of dense fog are possible in those areas, and with temperatures below freezing, icy spots could develop on roadways. Visibility could be reduced to one-quarter mile or less as well, adding additional hazards for motorists.
The fog should begin to burn off by the late morning, with temperatures also warming above freezing at that time.
