The NOAA HWT Spring Experiment is a yearly experiment that investigates the use of convection-allowing model forecasts as guidance for the prediction of severe convective weather. A variety of model output is examined and evaluated daily during the experiment and experimental severe weather forecasts are created and verified. The variety of model output allows us to explore different types of guidance, including products derived from both ensembles and deterministic forecasts.
The 2009 Spring Experiment will be held from May 4th through June 5th in the HWT facility at the National Weather Center in Norman. The experiment is scheduled to run Monday through Thursday from 8am to 4pm with a short wrap-up on Friday mornings. Participants are encouraged to join us for an entire week, but shorter visits may be possible pending available space. More information about this year's experiment can be found in the 2009 Spring Experiment Operations Plan (pdf).
