  1. 16-day rainfall outlook

    Warmer weather favored for the rest of the growing season Hotter and drier than normal for much of July

    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.

    What a Difference a Year Makes in the Weather

    Author(s): Aaron Wilson

    Things change quickly when it comes to weather and climate. 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.

  3. Weather Potpourri: Hot and Tropical – Turning Cooler This Weekend

    Author(s): Aaron Wilson

    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).

  4. Summer Weather Outlook

    Our attention now turns to the summer growing season and what is in store. Some things are different this summer.

    Much Like April, Cool Weather Lingers during the First Week of May

    Author(s): Aaron Wilson

    Temperatures in April were about 2-5°F below the long-term mean (1981-2010; Figure 1-Left) and included three major freeze events that brought some horticultural damage across southern counties and scattered minor reports of burned tips on alfalfa and wheat.

  6. Challenging Conditions Remain into April

    Temperatures and Rainfall: Temperatures will start the first 7 days of April 1-3 degrees F above normal. Rainfall will start April below normal about half of normal. That is some good news  as the end of March (as forecast) was very wet. However, most indications are for the remainder of April after the first week, temperatures will be near normal and rainfall slightly above normal. This will put pressure on early spring planting in April. Evaporation and evapotransporation will be held in check by closer to normal temperatures as we go through April.

  7. Wet Weather for the Rest of March

    Current Conditions...Soil moisture conditions remain wet due to last years very wet conditions along with an overall damp winter. Current soil moisture conditions can be found at the NOAA/NWS website: https://www.cpc.ncep.noaa.gov/products/Soilmst_Monitoring/US/Soilmst/Soilmst.shtml#

  8. Some Good Weather News

    A warmer than normal March is now anticipated now. This is a change toward the warmer side. This will speed up green up conditions and start evaportranspiration early this spring. This will also help to dry out our really wet soils a little bit at least. The bottom line is things are shaping up to not be as tough this spring.

  9. Growing Season to Last Through September

    Growing Season to Last Through September

    There is good news as it appears we will not have an early freeze in Ohio in September.

    Below normal temperatures will be with us to end August and possibly into the first half of September per the NOAA/Climate Prediction Center Week 2 early September temperatures, see attached image.

  10. Above normal temperatures and precipitation will rule July

    Above normal temperatures and precipitation will rule July

    Even though it has gotten a little drier recently, the pattern around a big high pressure to the west and south of Ohio favors a warm and humid July with rain chances. However, there will be swings in the the pattern from week to week.

    The first week of July will offer a very warm and humid pattern with increasing rain chances.

    Week 2 will offer a cooler pattern but with continued rain chances.

    Week 3 and 4 will return to above normal temperatures and rainfall near normal.
