the operational efficiency of using guidance from a mesoscale numerical model to improve sea breeze thunderstorm forecasts at and around the shuttle landing strip was assessed. the prognostic three-dimensional mesoscale (p3dm) model, developed as a sea breeze model, reveals a strong correlation between regions of mesoscale convergence and the triggering of sea breeze convection thunderstorms. the p3dm was modified to generate stability parameters familiar to the operational forecaster. in addition to the mesoscale fields of wind, vertical motion, moisture, temperature, a stability indicator, a combination of model-predicted k and lifted indices and the maximum grid cell vertical motion, were proposed and tested results of blind tests indicate that a forecaster, provided with guidance derived from model output, could improve local thunderstorm forecasts
