Neither of the TAFs issued by the Marquette Forecast Office at Sawyer International Airport (KSAW) or Houghton County Memorial Airport (KCMX) will change to the 30-hour service.

These TAFs will remain 24 hours, but still adopt the new format outlined above.  Detroit Metropolitan Wayne County Airport (KDTW), Minneapolis-Saint Paul International Airport (KMSP), General Mitchell International Airport in Milwaukee (KMKE), and Chicago O'Hare International (KORD) are the airports closest to Upper Michigan that will now be covered by a 30-hour TAF.
