hanges there will be in the weather in the short term. This is called weather forecasting. Many people rely on the weatherman to provide that information, but one method of weather forecasting is simply to use your eyes and brains. For example, if you see a rainbow in rainy weather in the evening, this is a sign that the weather will soon be clear and fine. Sometimes distant objects such as hills and tall trees seem to be very clear and near; this is a sign of much water vapor in the air, and then rain will probably come. If a fog appears just about sunrise in the morning, then the day will be arm. If the sunset is mostly red in color, then the following day will be fine. If the stars twinkle at night, then fine weather will come the next day 1.B2D3C4.A5.D Task 2: Wrong Weather Forecast M: Hey, Jane!
