    Author(s): Jim Noel

    After a cool spring, we are playing catch up fast with a warm June. June will end up being 1-3 degrees above normal with rainfall 50-100% of normal. The warm weather will continue for the rest of the summer. Maximum temperatures will likely be 1-3 degrees above normal in July. However, overnight temperatures will be even warmer, some 3-6 degrees above normal. Expect high temperatures in July to commonly be in the 85-95 range with overnight temperatures in the 65-75 degree range.

Recall 2019, a record wet start to the year for many across Ohio, only to see 26% of the state enveloped in moderate drought conditions by October. Though not nearly as wet as last year, it has been wetter than average through the first five months of 2020.

    After a long period of cold spring temperatures, the last couple of weeks have generally been above average by a degree or two in southeast Ohio to more than four degrees above average in north-central and northeast Ohio. Precipitation has usually been light during this time as well (less than 2 inches) except in a few heavier pockets across southern and eastern Ohio (Figure 1).
