The POPcast maps show the probability of precipitation for the current day and the next 48 hours at 6 hour intervals. The depicted contours on the maps indicate the likelihood that some form of precipitation will occur over the area. The value is blend of confidence that precipitation could occur, and the areal coverage expected to be impacted should the precipitation develop. If the value on the map indicated 60%, the correct way to interpret the forecast would be: There is a 60 percent chance precipitation would occur at any given point in the area. The maps for each region are available within the drop-down menu.
