You should also remember that severe weather events are predicted much worse than calm weather. On the fourth day it will be slightly off. The results from the accuracy analysis show that the forecast has been correct about 40% of the time at each location, which is higher than the expected 33 . Because they orbit at the same rate that the Earth rotates, allowing them to focus on one spot for most of their time in orbit, the satellites provide near-continuous images over a wide area. Analysis | How accurate were AccuWeather's 30- to 60-day highly Specifically, we assigned an error value: error=0, if the forecast matched with the observation at the location; error=+1 or +2, if the predicted precipitation was one or two terciles above the observed; and error=-1 or -2, if the predicted precipitation was one or two terciles below the observed. 5.
