The area was in the midst of the first Freeze Warning of the fall season Thursday morning. There certainly was frost on the pumpkin as listeners scrambled to find their windshield scrapers and the afternoon and evening before covered their plants and picked the remaining veggies out of their gardens. The Freeze Warning was short term in duration and was due to expire at nine a-m, followed by a bounce back in temperatures as the weekend drew near. During the four o’clock hour Thursday morning the temperature was 29 in the Marshalltown area. By comparison the high temperature on Tuesday was 76.
