Very Cold Soil Temps

10 Apr 2018 05:34 AM
The featured chart displays yearly time series of daily average four inch depth soil temperature for Kanawha (north central Iowa). This year's values are shown in red with a simple day of year average based on period of record data shown in black. Soil temperatures for early April this year are way below average and at the bottom of the observed range. Values shown are at freezing and with all the cold with recent snowfall, there is likely frost still in the ground. Getting soil temperatures to warm and even dry enough levels to support the spring planting will be a challenge. The exciting news is that a few days of much warmer air temperatures are on the way, but a major storm system to end the week is expected to usher cold air back into the state for next week.

Good: 8
Bad: 0
