Moisture concerns continue in the eastern Corn Belt locations with many locations still well behind on rainfall for May following spotty Memorial Day weekend coverage that appeared to fall a bit short of general expectations.

And while moderate to heavy rains are expected in the western Corn Belt over the next five days, forecasters see coverage remaining on the light side in the eastern half of the Belt.

The eastern Corn Belt generally saw 0.25-1.0 in. of rain, with locally heavier amounts, during the long holiday weekend with the heaviest amounts in the northern and central areas.

The No. 2 U.S. corn and soybean growing state of Illinois received the best of the weekend coverage, with isolated areas receiving 2 in. or more of rainfall, but through Tuesday morning, 30-day rainfall remained 2-3 in. below normal over much of the state according to National Weather Service data.

Rainfall over most of Indiana has also been at least 2 in. short of normal over the past 30 days, with deficits of 3-4 in. common across the southern half of the state.

In Ohio, much of the southern third of the state is 3-4 in. short on rainfall over the past month and a pocket of the Ohio River valley in southwestern Ohio has been even drier, according to the NWS data.

During this week, DTN Meteorlogix weather service forecasts showers and thunderstorms to cross the Midwest, leaving moderate to locally heavy rainfall west of the Mississippi and lighter rains in the eastern sector.

Crop moisture will remain at favorable levels in the western Midwest. However, the benefit to eastern areas will be much less, due to moisture deficits during May and the lighter rainfall amounts, DTN Meteorologix said Tuesday morning.

In a midday weather update Cropcast Weather Services notes that the southern Ohio Valley was short-changed the most by weekend rains. The system ended up producing a bit less coverage overall in the Midwest than expected, Cropcast says, according to a Reuters News Service report.

Cropcast predicts rains will focus on the western Midwest until late in the week, when light shower activity will start to move eastward.

Cropcast sees the best chance for rain in the eastern Midwest early in the 6-10 day period, and says this should give most areas a fairly good chance for some needed rainfall of half an inch or better.

The southeast U.S. and Delta are largely expected to see dryness concerns persist and expand during the next 10 days, Cropcast says.
