Soil temperatures continued to warm this week despite considerable variability in air temperatures (Fig. 1). Many locations throughout Ohio are now reporting daily average 2- and 4-inch soil temperatures in the mid-50s to low-60s. Daily maximum soil temperatures are routinely reaching 80°F with the increasing sun angle. Warming progress is likely to slow a bit this week. While daytime highs are expected in the 70s again on Tuesday, 50s and 60s are likely behind a cold front for the remainder of the week.
Much of Ohio experienced frost or freeze conditions this past Friday and/or Saturday night. In fact, many locations dropped below 30°F (Table 1), with unofficial observations as cold as 26°F! How does this compare to typical first freeze dates?
