Meteorologists can give a pretty decent idea of what the weather will be like about a week in advance but as far as really accurate, they get accurate about 24-48 hours out. Based on forecast scores and experience, about 2 to 5 days seems to be the average forecast for accuracy.
As a rule of thumb, the closer a weather forecast is in time, the more accurate it is. Long–range forecasts predicting the weather for more than 7 days in advance should be seen as a rough guide, as the accuracy of weather predictions falls considerably around the one-week mark.
Additionally, can we predict weather? Meteorologists are able to predict the changes in weather patterns by using several different tools.
