  1. Brief Break from Wet Weather Continues before More Wet Weather Returns

    We have had a few weeks of colder and drier overall weather after the very warm start to October. We expect dry weather through this Thursday except for a few lake effect showers in northeast Ohio about the middle of the week.

  2. Warm and Wet October Expected

    After a very wet September across all but northwest Ohio in the Maumee River basin, we can expect more of the same in October. September saw some locations in the top 5 wettest on record for Ohio like Columbus and Dayton.

  3. Wetter Than Normal Pattern into October

    There is no change from last week as an overall wetter than normal pattern will persist into the October harvest season.

    The one thing that has changed is that temperatures after last week's hot weather do not look as warm into October. Temperatures are now more likely to be normal or maybe a degree above normal.

    It still looks like the first freeze is on track with a near normal arrival. Most places tend to be in the October 10-20 range in Ohio from northwest to south.

  4. Warmer and Wetter Pattern to Impact Much of the Harvest Season

    The warmer pattern will continue at least into the start of October across Ohio.

    The remnants of Florence went mainly east of Ohio with only light rainfall amounts. Temperatures will heat back up into the 80s for much of the rest of this week. Normal highs are in the 70s and lows in the 50s. We expect highs this week mostly in the 80s and lows in the 60s to near 70.

    The next rainfall system will move across the region later Friday or this weekend. Another system will move through by the middle or the end of next week.

  5. Tropical Moisture Invades Ohio

    Author(s): Aaron Wilson

    It was quite the wet week across the state of Ohio! Scattered thunderstorms throughout the week brought isolated 1-2” rainfall amounts. The big story began on Friday night, as a stalled out front provided a path for the remnants of Tropical Storm Gordon to move through the region, bringing steady to moderate rain and gusty winds from Friday night through Monday morning.

  6. HARVEST SEASON OUTLOOK

    Hot weather, possibly close to the hottest weather of the season is on tap over the next two weeks. This should help make corn stalks brown up fast. However, with that heat, high dewpoints or moisture will also accompany the hot weather. This means soil drying will be slower than you would normally expect with high temperatures due to a limit on the evapotranspiration rate. The hot weather will be fueled in part by tropical activity in the Pacific Ocean driving storms into the Pacific Northwest into western Canada and a big high pressure over the eastern U.S.

  7. ...At Least One Good Rain Event Per Week for the Rest of August...

    Summer rainfall has been on a wild swing. We have been going back and forth from wet to dry and now we are looking toward a bit wetter pattern again.

    The outlook for the rest of August calls for slightly above normal temperatures (about 1-2F). Rainfall will likely average 2-4 inches with normal being near 3 inches inches. Isolated totals could reach 5 inches through the end of August.

  8. Overall Drier Pattern into Early August

    The pattern change from wet to dry has arrived. For the remainder of July expect temperatures not too far from normal, some days above some days slightly below. Nothing real extreme to note in the temperatures. Humidity will also fluctuate from higher to lower to higher. Overall, moisture in the air will be typical for July. The one thing that will be different is the rainfall pattern. July has been a drier month for many areas. After a few showers or storms early this week, the next rain chance will be late this Friday into the weekend.

  9. Weather Map Week of June 24

    Hot streak ahead!

    After a really wet period last week and even some flooding in northwest Ohio, we will be seeing a switch toward hotter weather and a drier window from Thursday into the weekend.

  10. Weather Map Week of June 10

    Rest of June warmer than normal with high rainfall variability

    Not much has change since last week in terms of the outlook. The rest of June is likely to be warmer than normal with high variability of rainfall but tendency to above normal rainfall.

    It appears a heat dome will be centered in the south central U.S. this summer with periods where it shifts over the corn and soybean belt and Ohio Valley. The next surge of heat will come this weekend into early next week. With these surges come a ring of fire of storms around the heat dome leading to locally heavy rainfall. However, that rain will be scattered in nature.
