The list is given in chronological order with a brief description of the damage or event and who reported it. TWEB's are forecasts for a given route, example Cleveland to Columbus, for a 15 hour period. TWEB's are issued 3 times daily one hour after the TAF's. These data are primarily reported in an alphanumeric code formatted for aviation users. In addition to this data special notes may be posted in the remarks section.
Special observations contain all the elements normally included in a record observation.
