  • Surface fields of 3 km forecast
  • Surface fields of 1 km forecast
  • East-west vertical cross-sections of veritcal velocity and equivalent potential temperature
  • Model extracted soundings west, east and at the dryline.
  • Model extracted mean soundings west, east and at the dryline but averaged along the dryline direction.
  • Surface moisture convergence from 1 km forecast
  • Cells A and B;  Cell B and C regions
  • Cells A;  Cell C region
