In the realm of meteorology, the accurate prediction of severe weather events, such as thunderstorms producing damaging hail, is crucial for ensuring public safety and minimizing potential damages. Recently, Jonathan Douglas, a senior studying meteorology at the University of Oklahoma, conducted an internship to assess the modeling potential of the Rapid-Refresh Forecast System (RRFS), a cutting-edge model developed at the Global Systems Lab in Boulder, Colorado.

Douglas, under the mentorship of Amanda Back, analyzed 154 hours of severe weather observations to evaluate the RRFS’s ability to simulate strong thunderstorm updrafts and hail production. His research focused on two key aspects of the model: the accuracy of storm placement and timing compared to actual observations, and the comparison of simulated hail sizes with radar estimates to determine forecast reliability.
The findings revealed that while the RRFS excelled in replicating storm placement at the right time, it faced challenges in accurately representing storm strength. Compared to other existing models and observations, storms generated by the RRFS were smaller in size, had lower maximum heights, contained less water, and lacked intensity. However, the model showed promise in forecasting hail growth, with simulated hail sizes closely aligning with observed data.
Douglas’s internship provided valuable insights into the strengths and limitations of the RRFS, highlighting areas for improvement in storm intensity prediction while showcasing its potential for enhancing hail forecasting accuracy. His research contributes to the ongoing efforts to advance meteorological modeling and improve severe weather prediction capabilities.
In a field where precision and reliability are paramount, studies like Douglas’s play a vital role in refining forecasting tools and enhancing preparedness for severe weather events. As meteorologists continue to harness innovative technologies and models, the quest for more accurate and timely weather predictions remains a driving force in safeguarding communities and infrastructure from the impacts of extreme weather phenomena.
