KRAH: SVR 1954z





ProbSevere Analysis: 2 main areas of interest, partner took northern cell and I took southern. Focused on the high ProbSevere area of southern cell.
  • Started looking at this cell with ProbHail & ProbWind were steadily about 80% with development  along the southern part of the line. 
  • Focused on that cell from ProbSevere, looked at the 1 min Vis and saw a nice look and development to the Cbs. Even though Z aloft wasn't that big, the trend was increasing.
  • Thought threat would be marginal for hail and more so wind from precip loading and cells that have had a history throwing out outflows. 
  • Didn't have great confidence in this cell, particularly when the GLM data didn't show an large uptick in lighting event output prior to issuance.
  • Result: Cell quickly collapsed, ProbSevere values dropped and no reports were received...yet.
