July 12 The worst drought in a quarter century
tightened its grip on the Midwestern United States over the past
week as sweltering temperatures and scant rainfall punished corn
and soybean crops across the region, a report from climate
experts said Thursday.
Nearly two-thirds of the nine-state Midwest region was in
some stage of drought in the week ended July 10, up from just
over 50 percent a week earlier, according to the Drought
Monitor, a weekly report on drought throughout the country
compiled by U.S. climate experts.
A third of the region was in severe to exceptional drought,
up from about a quarter of the region a week earlier, it said.
"The most anomalous conditions covered the lower Ohio
Valley, southern Great Lakes, and middle Mississippi Valley,
where daily highs averaged 10 to 13 degrees above normal.
Additionally, these areas received scant rainfall if any," said
Rich Tinker of the Climate Prediction Center.
"The worst conditions (D3 to D4) were assessed along and
near the lower Ohio River and in northeastern Indiana, where
rainfall was 7 to 11 inches below normal for the last 3 months,"
he said, referring to the top two categories of drought, extreme
The deepening drought has dragged the yield potential of the
developing soybean crop and the pollinating corn crop, which is
in a growth stage when its water needs are highest.
On Wednesday, the U.S. Department of Agriculture slashed
production forecasts for both crops due to the drought, joining
scores of private forecasts that have sent grain prices to
The whole of Iowa was classified as abnormally dry as of
July 10 and 12.7 percent of the top corn and soybean producing
state was in severe drought, up from 0.8 percent the prior week.
Harder-hit Illinois, the No. 2 corn and soy state, was 66.28
percent under severe drought or worse, up from 40 percent the
Severe to exceptional drought covered 80.15 percent of
Indiana, versus 68.84 percent the prior week.
Conditions in Missouri also deteriorated, with 82.54 percent
of the state un severe drought or worse, compared with 78.83
percent the week before.
Rain was expected to move across the Midwest over the next
10 days, including parched southeastern areas, but coverage may
be spotty, forecasters said on Thursday.
