Drought Monitor: Soil Moisture Deficits Remain in Iowa

The National Drought Monitor says while improvements were made across Iowa and southern Minnesota, substantial precip deficits remain. Moderate drought conditions also expected over eastern Missouri and western Kentucky, while some drought improvements were also noted across Indiana and Illinois.

Across Nebraska, long-term deficits in precipitation and soil moisture are still prevalent. "To maintain current conditions, which means receiving rainfall at climatological levels, areas of Nebraska would need to receive nearly 1 inch per week  Anything less, combined with increasing agricultural needs (0.20 inches per day for corn fields), would lead to a drying of the soils," states the monitor.

Meanwhile across the Dakotas and much of Minnesota and Wisconsin, further reductions in drought coverage were noted. "Heavy rain came to eastern South Dakota. This fell right on the D1 region in eastern South Dakota," states the monitor.

In the Central and Southern Plains, reductions in the coverage of exceptional (D4) and extreme (D3) drought were made across western Texas and southeastern New Mexico. "Rains this week were not exceptional, but a recent wet pattern has helped to alleviate some of the dryness across that region," it states. "Heavy rains across central Texas, occurring right up to the data-cutoff, prompted improvements there, but poor groundwater storage and slowly responding reservoir levels continue to mitigate the recovery, so the only modest reductions in coverage were indicated."

Meanwhile across southwestern Kansas, River Forecast Center (RFC) precipitation data indicated small pockets of significant rains (0.5 - 1.5 inches), so small areas of D0 and D1 were removed.
