"The purpose of this paper is to show that the potential for snow squalls was clearly indicated by the forecast variables used in the Wintertime Instability Index (WINDEX), method of forecasting non-lake effect snow squalls (see accompanying Technical Attachment no. 93-11A). WINDEX uses the NGM low level temperature differences, boundary layer relative humidity, and an increase in the lifted index over a 12-hr period to produce a Wintertime Instability Index""--Introduction.
