Accurately Predict Thunderstorm Activity with Ease

Thunderstorm Calculator by Piet Jonas simplifies weather forecasting, allowing users to gauge thunderstorm likelihood based on various meteorological data inputs.
This application provides users with a functional tool for calculating the distance of a thunderstorm by measuring the interval between a flash of lightning and the subsequent sound of thunder.
Instructions for Use:
