Description:

"Basic Weather keeps a continuous record of precipitation threat scores, no precipitation threat scores, and bias for a 60 station network for comparative purposes dating back to 1971. The bias scores (-) began in 1972 for 24-12 hrs. and 1975 for 36-12 hrs. The LFM POPS scores are included in the yearly comparative statistics for the first time in 1982, but we have been looking at them daily and monthly since they started. Basic Weather selects a POP station as a categorical pick (.01"/12-hr.period) if the POP "chance" is 45% or greater. These records are kept to evaluate the effectiveness of the "man'" and the guidance monthly, seasonally, yearly and longer in order to evaluate objectively how the "man" and the model, including the LFM POPS, compare and to see if changes in the model are positive or negative relating to precipitation output"--Introduction.
