You can watch the weatherman on TV, to find out what the weather will be like.
When the sun is shining, the weather is good and there are no clouds in the sky.
But some days are cloudy. On some cloudy days, it begins to rain or snow. You need a raincoat, umbrella and boots on a rainy day. Rain makes the flowers and grass grow.
Sometimes, the weatherman will say that it will be windy. It is dangerous if the wind is very strong. A hurricane or tornado is very dangerous.
Once in a while, the weatherman says there will be hail. Hail stones are small pellets of ice that fall from the sky.
Sometimes, the weatherman will say that there will be snow. If there is a lot of snow, you need a hat, coat and boots.
Sometimes, the weather forecast is wrong. That is not good if you are planning a picnic.
