After a cooler and drier November, our attention turns to the winter and spring outlooks.
With a weak La Nina ongoing again this upcoming winter, what will it mean for Ohio? La Nina is only one of many factors that impacts our weather and climate.
After a cool start to June, temperatures have been running 4-10°F above average over the last 10 days. The airmass was quite a bit more humid as well, with numerous “gully washers” across the state.
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.
The National Weather Service Frost/Freeze program has ended for the season as many areas have experienced 1-2 hard freezes (28°F) over the last three weeks.
