A freeze warning will again be in effect for the Chicago area early Thursday as falling temperatures threaten to kill vegetation that grew during the record March heat.
The National Weather Service issued a freeze warning from midnight until 8 a.m. Thursday for northern Illinois, including Cook, DeKalb, DuPage, Kane, Kankakee, Lake, McHenry and Will counties.
A freeze warning means sub-freezing temperatures that will kill crops and sensitive vegetation are highly likely, according to the weather service.
Temperatures are expected to drop below 32 degrees again away from Downtown Chicago for several hours late Wednesday and early Thursday, the weather service said. Some areas could get as low as 28 degrees and a “hard freeze” is possible.
The record warmth in March prompted vegetation to grow much earlier than normal, that vegetation could be damaged or killed by the sub-freeing temperatures, the weather service said.
