Today’s activities took us just a little further east into the Bismarck, Billings, and Cheyenne CWA’s. The Cheyenne group would later move to the Aberdeen CWA as activity shifted out of the CWA. Participants were able to analyze the LAP products and later the NUCAPS soundings to get an idea of where severe convection was most likely. The CI product was also monitored for initial development during this period. As convection grew and matured, participants utilized the ProbSevere Model and Lightning Jump to identify significant changes in the storm that would warrant the issuance of a warning. The ENI total lightning products were utilized throughout the life cycle to monitor the evolution of the mature cells. The 1-min satellite imagery was helpful when monitoring for initial convective development, and seeing that development as it occurred, along with failed convective attempts. Additionally, the 1-min imagery along with 10-min winds generated from the imagery aided a forecaster in his assessment of the near-storm environment.
