Once you know how to pick out the TAF forecast
time periods, the same logical sequence that we
saw in METAR will follow. Below, a TAF is broken
down to highlight its individual segments. Key
words (and their definitions) indicating a new time
period has started are in boldface

(3) Alaska and Hawaii will use 4-letter
identifiers beginning with "PA" and "PH"
respectively.
(4) Changes are planned to incorporate
3-letter identifiers for those weather
reporting stations where numbers and
letters are now used (e.g., W10 to KHEF)
