The problem of precipitation forecasting in New England has been emphasized by the needs of the many varied industries of that region for accurate forecasts when rain or snow is in prospect. Some are especially interested in the type of precipitcttion, others in amourts. Among tbose which become extremely dependent upon estimates of the amount of future preci itation in directing their operations are the power and Eght companies, transportation interests, the U. S. Engineers, and others. Because of this need for forecasting service, the newly established Weather Bureau forecasting research unit a t Boston initiated the project described in this paper; the problem of forecasting the type of precipitation was not included in the project, since it is a separate one and fully as complex as that of forecasting amounts. In this study an attempt was made to combine the techniques of several previous studies and apply them to the particular problem of forecasting for Boston the precipitation amounts to be expected from winter coastal storms. Earlier investigations by Rodgers [l] and by Miller [ 2 ] , which were concerned with the typing and the recognition of pressure patterns which lead to Atlantic coastal developments included no attempt to evaluate quantitatively the resultant precipitation. Brier [3], however, demonstrated in his study of the T. V. A. Basin that objective techniques could be successfully employed in making quantitative forecasts of precipitation. This study, patterned loosely after Brier’s investigation, was made with a threefold objective: 1. To develop a practical method for computing the precipitation amounts from coastal storms, using data available a t the time of the forecast. 2. To show the relative values of the factors contributing to the computation of precipitation amounts. 3. To test the reliability of specific factors now favored by some of the Boston forecasters in determining precipitation amounts.
