Severe Thunderstorms Possible for the Great Lakes into Ohio Valley; Heavy to Excessive Rainfall Over the Southern Plains

Severe thunderstorms will race along a cold front from the Upper Mississippi Valley into the Great Lakes and Ohio Valley with the main threat being damaging winds. The tail end of this front will possibly produce heavy to excessive rainfall across the southern Plains into the Lower Mississippi Valley through Saturday. Finally, Major-to-record river flooding continues across the Carolinas. Read More >

The Office of Water Prediction (OWP) conducts operational, development, and field support functions. The OWP operationally supports and delivers science-based, integrated, consistent, timely, reliable and accurate water resources monitoring, prediction and diagnostic information to the Nation. It operates and maintains numerical water resources analysis and forecast modeling and data assimilation systems in collaboration with National Weather Service (NWS) National Centers for Environmental Prediction (NCEP), 13 regional NWS River Forecast Centers, Federal water partners, academia and stakeholders. OWP development functions focus on advancing the maturity and transitioning to field operations applied research (R2O) from within the National Oceanic and Atmospheric Administration (NOAA), partner agencies, and academia, as well as supporting and improving core OWP operational capacity.

WPOD collaborates across all levels of the NWS and NOAA, and with federal partners, to provide consistent national operational services, which complement, support and enhance water resources decision support services delivered by River Forecast Centers (RFCs) and other field offices. Leveraging the assets of the National Water Center (NWC), the WPOD performs major functions, which are inherently interconnected and include: 

  • Analyze and Integrate Data through the routine production, analysis, and delivery of a suite of national hydrologic data and services;
  • Maintain Situational Awareness through continuous assessment, interpretation and collaboration of hydrologic data and model output, and related decision support activities;
  • Ensure Service Backup/Continuity of Operations by providing a service backup capability for RFCs to conduct limited, remote operations when needed;
  • Deliver Impact-based Decision Support Services by proactively supporting, and responding to, stakeholder-defined needs and requirements for information which supports decision making during high impact events, as well as routine, high-value operations; and
  • Facilitate Service Development and Operations to Research by providing operational support and feedback, and promoting innovation with respect to new water resources services.
The WPOD combines these functions to support a fully-integrated field structure that delivers first class water resource services to partners and customers across the nation. Moreover, the WPOD supports water-related services across other parts of NOAA, as well as other federal agencies to ensure a seamless suite of integrated water resource prediction services.
