Traditionally, the accuracy of the weather forecast is extremely difficult to achieve. In the course of time, the accuracy of the weather forecasts has changed consistently. Today, the accuracy of the weather forecast is very high compared to weather forecasts of the past. Nevertheless, it is still impossible to reach the 100% accuracy of the weather forecast.
In this respect, it is possible to refer to One week weather report. In fact, the report contains a relatively accurate weather forecast. The weather report is practically absolutely accurate in regard to precipitation. The forecast concerning the temperature is less accurate but still the difference between the forecasted and observed temperature rarely exceeds 5-6 Far that proves that the forecast is quite accurate.
At the same time, the existing inaccuracy of the weather forecast is quite natural, taking into consideration numerous factors that influence the weather. As the matter of fact, the weather is extremely changeable and there a lot of factors that influence the weather. In such a situation, it is very difficult to forecast the weather, especially in a long-term perspective. This is why weather forecasts rarely exceed one-two weeks. At this point, it is important to stress the fact that the longer is the period of the weather forecast the higher is the risk of error and inaccuracy of the forecast, whereas a few days or a week weather forecast can be very accurate.
Thus, in conclusion, it is important to emphasize the fact that the weather forecast cannot be absolutely, 100% accurate. The weather is changeable and the modern science cannot provide the 100% accuracy of weather forecasts.
