Important Conclusions:
Forecasters using 1-minute radar updates perceived significantly more information than forecasters using 5-minute radar updates and demonstrated improved projections of storm activity in the hail and wind cases worked, owing to earlier perception of severe weather precursor signatures and the ability to more easily observe strengthening and diminishing trends in storms. Such improvements in situational awareness from the use of 1-minute radar updates resulted in superior severe warning lead times and supported correct rejections of unverified threats.

Significance:
This paper summarizes qualitative findings from the 2013 Phased Array Radar Innovative Sensing Experiment. It builds on results presented in the published Impacts of Phased-Array Radar Data on Forecaster Performance during Severe Hail and Wind Events. This paper demonstrates efforts that are being made to learn about the forecaster warning decision process through the use of social science techniques.
