The National Weather Service has issued an advisory for potential frost or freezing conditions in East Central Illinois on Tuesday morning.
A cold front is expected to push across the area late Sunday night and will usher in a chilly air mass to central and southeast Illinois starting on Monday. The chilly air mass is expected to prevail through much of the upcoming week.
A combination of high pressure, a clear sky and light winds is expected to allow temperatures to drop off quickly on Monday evening.
Overnight low temperatures are forecast to dip into the lower to middle 30s by dawn Tuesday.
With the potential of widespread frost or possibly freezing temperatures, sensitive outdoor plants may be killed if left uncovered.
