Hastings, NE (SVR #2): Losing ProbSevere guidance due to cell merger

Was monitoring a developing cell mainly with base/dual-pol data. Was on the edge of a warning decision and looked to ProbSevere for added confidence. During the 20:08z scan had a ProbSevere of 54% (fig 1) with no growth of glaciation rate. During the subsequent 20:10z scan the cell merged with the northern cell and quickly jumped to 84% (fig 2). Lost confidence in this prob due to the merger. Ended up warning on base data info along and just the trend of the increasing ProbSevere from the previous scans. –Cattywampus
