Abstract : The report describes a quasi-objective technique for preparing 24- to 36-hour horizontal weather depiction forecasts, using a blend of numerically produced guidance material and weather satellite data. Relationships between the Fleet Numerical Weather Central (FNWC) 500-mb SD analysis and cloud patterns observed by weather satellites are illustrated. Objective methods for modifying the 500-mb SD progs, based on the satellite-observed cloud patterns, are described. Methods are outlined for forecasting precipitation areas, amounts and types, cloud types and cloud top heights. Verification techniques and results are presented. (Author)
