This variation is only partly due to the range of latitude the continent spans.

(2) If the forecaster expected a widespread area of precipitation with 100% coverage to approach, but he/she was only 40% certain that it would reach the forecast area, this would, as well, result in a "40% chance of rain" at any given location in the forecast area.

Peer-reviewed research has concluded the practical limit to forecasting specifics is on the order of eight to 10 days. So how did AccuWeather's forecasts weeks and months into the future do? They were about half right.
