Experimental Forecast Program

2015 Spring Experiment Participant Information »

The HWT Experimental Forecast Program (EFP) is focused on the use of computer models of the atmosphere to improve predictions of hazardous and convective weather events from a few hours to a week in advance, and over several counties to the continental U.S. The EFP supports the NWS goal to increase lead-time and accuracy for weather and water warnings and forecasts.

The NOAA HWT EFP Spring Experiment is a yearly project 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 project 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 2015 Spring Forecast Experiment will be held from May 4–June 5 in the HWT facility at the National Weather Center in Norman. The Experiment is scheduled to run Monday through Friday from 8 am to 4 pm.
