(Ames, Iowa) – The latest Iowa Drought Monitor (Released Thursday, June 1) indicated a continued trend toward dryness across the State. Only the north-central & northeast counties are free of drought conditions.The report is released every Thursday, and does not take into account rain received since the report was issued. Atlantic finally received some decent rain Thursday, at slightly more than nine-tenths of an inch. The last time we received over nine-tenths of an inch, was May 5th (.94″).  The National Weather Service says a high-pressure system parked over the Great Lakes continues to block any organized weather system from entering the state.

White-No drought; Yellow-Abnormally dry; Tan-Moderate drought; Orange-Severe drought; Red-extreme drought; dark red-Exceptional drought.

Drought areas are categorized from D-O (no drought) to D-4 (Exceptional Drought). The Drought Monitor shows drought conditions continued expanding across the region, from D-O to D-1 (Abnormally Dry) in parts of Illinois, Iowa and Missouri. D-2 soil/drought conditions expanded in Iowa and Missouri, while D-3 (Extreme Drought) conditions grew in Missouri. As of May 28th, USDA data revealed more than half of the topsoil moisture was short or very short in Iowa (50%), Missouri (62%), and Michigan (68%), and 40% or more was short or very short in Wisconsin (45%), Ohio (45%), Illinois (42%), and Indiana (40%).

The story for the Midwest was continued drying of soils, low streamflows, and mounting precipitation deficits over the last 1 to 3 months.
