This 'triangle with dot' shape is the symbol for sleet. Sleet is frozen rain. It forms as rain falls into a layer of air with a temperature below freezing deep enough for the droplets to freeze before they reach the ground. If the atmosphere above the cold layer is unstable enough then one can experience thundersleet - a thunderstorm which contains only sleet.
