A method and apparatus for forecasting the likely occurrence of convective weather
events, such as thunderstorms. An image filter is used to identify areas of interest
within a meteorological image that are likely to contain convective weather. The
image filter and an image difference processor identify areas within the meteorological
image that are likely to experience a growth and/or decay of weather events. The
meteorological image, interest image and growth/decay image are processed to produce
the short-term forecast.
