"This signifies the end of the growing season, and all tender plants should be protected. These lows are 15 to 20 degrees below the average, with the record low for (Thursday) morning standing at 34, set in 1937," Chandley said.
Freezing temperatures are likely to arrive by Saturday morning. A freeze watch has been issued from late Friday night through 10 a.m. Saturday.
