Delve into the innovative forum of collaboration between researchers and practitioners at the NOAA Hazardous Weather Testbed, focusing on experimental warning and forecast programs, pioneering projects between NSSL and WFO-OUN, and the arrival of the SPC and annual spring experiments. Witness the evolution of technology infusion in weather forecasting and the operational impacts observed in tornadic supercells.
