For the sake of brevity, it uses some contractions and can contain complex meteorological terms. Included at the end of the discussion are temperature and probability of precipitation forecasts that follow a format similar to the <a href="ccff.htm">coded cities forecast</a>. Finally, if any watch, warning, or advisory is in effect (except for severe thunderstorms or tornados), it is included at the end of the AFD. <h4>Example</h4> <div align="center"><table width="430" cellspacing="0" cellpadding="5" border="1" bgcolor="#eaeaea"> <tr> <td><pre> FXUS64 KFWD 140902 AFDFTW AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 400 AM CDT THU SEP 14 2000 UPPER LOW LOCATED OVER W TX AND RESPONSIBLE FOR MUCH OF THE CLOUD COVER OVER N TX EARLY THIS MORNING...WAS MOVING WWD ACCORDING TO WATER VAPOR SATELLITE.
