Weather predictions can be inaccurate sometimes because weather predicting depends on how many eyes are there in the upper atmosphere. Thus, weather is always constantly moving. There are lots of measurements to be used in forecasting the weather just like measuring of temperature the timid and the humidity, air pressure, the direction wind and its speed, dryness, and rain. Also, there are planes, balloons used for weather and space station just to spread data to weather location on the ground but still there are times that forecasted weather may be often wrong although Meteorologists explain the computer-generated predictions with a comparison between dissimilar scientific models and squeeze them by relying on the flow of real-time data coming from the field.
We don’t know what the weather may bring because we don’t hold it. Therefore, it just normal that everybody can be inaccurate in predicting what will be happening.
