This option plots convective outlooks (thunderstorm forecasts) issued by the National Weather Service's Storm Prediction Center (SPC) in Norman, Oklahoma. These are centralized human-produced forecasts issued several times a day, and are used to help provide guidance to National Weather Service forecast offices. They are also used frequently by storm chasers, pilots, and hobbyists.
To use this option, you must have imported a convective outlook as part of your raw data set or from one of the choices in Internet > .
Advanced users can modify the color scheme by changing the contents of the file DIGATMOS.CCC in the Digital Atmosphere directory using a standard text editor such as Notepad (never use a word processor such as Microsoft Word or you will corrupt the file). This file contains self-explanatory instructions for modifying the hexadecimal numbers used to determine colors of the various threat boundaries.
If there are any problems ingesting a bulletin, the problem is most likely an error in the composition of the bulletin. It is not necessary for the header to be intact, but the "STORM PREDICTION CENTER" title must appear in the bulletin along with the convective outlook type, valid times, and standard bounding locations of each threat area.
