A SNOWFALL PREDICTION METHOD FOR THE ATLANTIC SEABOARD

Abstract

Melted precipitation and snowfall data from eight winters were used to develop a snow and melted precipitation prediction model associated with 850-mb cyclones along the Atlantic Seaboard. Results indicate that the major potential for heavy snow exists in a band extending from 75 to 225 mi to the left and from 350 to about 1,000 mi ahead of the 850-mb cyclone in the 12-hr period beginning 6 hr after routine upper air observation time. Application of the prediction model of snow amounts to some storms from the 1968?1969 winter season indicate they provide valuable guidance to the forecaster during periods of East Coast storms.
