Midwest
Precipitation extremes in the Midwest have a major impact on the region’s resources, economic sectors, and residents. Over the last century, precipitation trends in the Midwest have been moving towards wetter conditions and fewer droughts than the region experienced in the early 20th century. However, the Midwest has still felt adverse impacts during recent droughts, particularly in 1988 and 2012. These adverse impacts include limited barge transportation on major rivers (including the Mississippi River), decreased agricultural production, challenges for municipal water supply and quality, and reduced productivity for hydropower. An added challenge in recent years has been the tendency to transition from drought to flood and back to drought within short time spans, sometimes within a matter of months. NIDIS and its partners launched the Midwest DEWS in response to the 2012 drought, which highlighted the need for additional drought early warning and preparedness in the region.

Featured Activity
Midwest DEWS Partners Meeting: Presentations Now Available
NIDIS held the Midwest Drought Early Warning System (DEWS) Partners Meeting on August 20–22, 2024 in Indianapolis, Indiana. This regional gathering provided the opportunity for partners in the Midwest DEWS to share and discuss ongoing drought-related activities, learn about new and innovative drought research and resources, explore emerging issues and opportunities, and identify collaborative paths forward to advance drought early warning and preparedness in the region. Presentations from the meeting are now available, and a meeting recap is coming soon.
Regional Activities
The following table highlights activities in the Midwest that are ongoing efforts related to drought, involve multiple partners, serve as a unique way to address regional drought needs, and are related to at least one of the components of drought early warning. Please contact Molly Woloszyn (molly.woloszyn@noaa.gov) for more information about the table or to inquire about getting an activity added to the list.

Observation + Monitoring
When monitoring drought, it is important to look at data across the spectrum—from the atmosphere, land surface, and water availability below the surface. The list of data and maps below has been customized for the Midwest, and provides a snapshot of conditions across that spectrum, including precipitation and temperature departure data, evaporative demand, streamflow, soil moisture, groundwater, and various derived indices for monitoring drought in the region. Monitoring for the impact of drought is also important, and resources to submit conditions and/or impacts and view conditions are provided.

Planning + Preparedness
There is little that can be done to influence the weather patterns that cause drought, but preparatory actions and policies can help communities cope with drought impacts. Drought planning can ensure continuity of public services and quality of life. Drought planning can be done at the local and/or state level, or integrated into existing plans (e.g., hazard mitigation planning, land-use planning).
The Midwest DEWS partnered with the National Drought Mitigation Center to analyze drought mitigation and response actions in state and county plans across the region. This database of drought mitigation and response actions can be shared by request. Please reach out to Molly Woloszyn for more information.
Regional Drought Planning Resources
Prediction + Forecasting
When will drought affect me? How long could it last? This section includes resources for drought prediction and forecasting on what could be ahead, including the short-term (e.g., 8–14 day forecast), seasonal to subseasonal (e.g., monthly), and future climate projections (e.g., mid-century). The appropriate time scale will depend upon how this information is being used (e.g., drought response, mitigation management action, long-term planning). Weather and climate prediction is an evolving science, as researchers continue to find ways to improve models and forecasting capabilities at various time scales.

Communication + Outreach
An important component for drought early warning is communicating this information to stakeholders across the Midwest region that need this information in order to make more informed decisions. There are various ways drought information is communicated across the Midwest, including a monthly webinar series, a quarterly climate report, and the Midwest DEWS email list.

Research + Applications
Research to better understand drought in the Midwest and its development, persistence, improvement, and interaction with other hazards is critical to providing timely and reliable information, products, and services in support of drought early warning. This page highlights research projects that are studying drought in the Midwest region, with support from NIDIS.
