After above-normal precipitation in early summer that saw 33 straight days with recorded rainfall at stations monitored by the National Weather Service’s Wilmington office, recent totals have dwindled to a few drops.
When the National Drought Mitigation Center releases its new map Thursday based on the latest data, it’s likely that a growing section of western Ohio will be categorized as “abnormally dry.”
New Carlisle has measured a measly 0.6 inches, Hamilton 1.4 inches and the Dayton International Airport just 0.15 inches in the past month.
The airport’s gauges are almost three inches below normal over two months and eight inches down since October 2012.
Dry weather has been most widespread over the past month or two, which doesn’t qualify — yet — as the drought that is widespread west of Indiana and advancing eastward.
“You would have a hard time convincing farmers around Ansonia and Union City that they aren’t experiencing an actual drought,” said Sam Custer, director of agriculture and natural resources in the Darke County extension office.
“Most of them have seen less than .2 of an inch since July 1 and they’ve been hammered with extra dry conditions for the past three years.”
Two counties to the south, Butler County extension office educator Cindy Meyer hasn’t been “getting reports about crop losses. I think most people are under the impression that we are still OK because we had so much rain early in the summer. The truth is that most of our crops, plants and trees need an inch of water per week. We’re definitely in a deficit.”
Rainfall at the Butler County Regional Airport is 2.11 below normal for the past 30 days and five inches down since October 2012. Although the Cincinnati-Northern Kentucky Airport is 1.37 below normal for the past month, it’s 2.2 inches above average for the past year.
Jamie Simpson, chief meteorologist for WHIO-TV, said the area finished last year several inches below average “and now we are almost seven inches below average for this year. However, we have not had the intense heat we did last year and that means the overall impact is much less.”
Until mid-July, “it rained or snowed on 60 percent of the days this year, which is far above average. However, the amounts were not that great when compared to average,” he said.
Restrictions on watering lawns, which have been common in area communities in past years, have not been imposed this year.
“I don’t foresee any this summer,” said Ronald Volkerding, director of sanitary engineering for Greene County.
NWS meteorologist Jim Lott said the I-70 corridor from south central Indiana into Ohio “has been the worst in our region over the last 90 days. In general, rainfall there is nearing just 50 percent of normal for the period. But Butler and Warren counties have some areas that are 1 to 3 inches above normal over those 90 days.”
Lott “wouldn’t be surprised if the area of moderate drought expands into Indiana and the abnormally dry portion of the map spreads in Ohio. A cold front coming through later this week doesn’t look like it will be a drought buster. We will get some showers, but they may be light. It’s going to dry out again through the weekend.”
Custer said that this year’s crops are now being harvested. Darke County “has gone from what looked back in July to be a record-breaking yield to what will now be a pretty average harvest. If we don’t get some moisture back into the soil by Oct. 1, that’s going to affect the next round of planting.”
