Present numerical weather products do not include a current analysis or a forecast of large scale occurrence of cloudiness and precipitation. The model used in this paper uses vertical velocities and dew-point depressions at the levels of 850, 700 and 500 mb as inputs to a diagram which determines the accompanying weather parameter. Good results were obtained for a current analysis, but the prognosis scheme used proved to be unsatisfactory at the present time. The model is programmed for the Control Data Corporation 1604 digital computer to utilize the operational output of machine-processed data and analysis produced by the U. S. Navy Fleet Numerical Weather Facility FNWF, Monterey, California.
