COLUMBIA — A freeze warning has been issued from 1 a.m. to 9 a.m Friday.
The National Weather Service in St. Louis predicted a low around 31 degrees Friday morning. Temperatures were expected to dip below freezing a few hours before sunrise and rise above freezing about an hour after sunrise.
Boone County and surrounding counties were expected to be hit with widespread frost. A high pressure system will produce clear skies and light winds, which are ideal for frost development, according to the weather service.
The National Weather Service is warning those with outdoor potted plants to either cover them or bring them inside because the colder temperature might kill them.
Cities expected to be affected include Columbia, Mexico, Quincy, Hannibal and Bowling Green.
