Nice evening in P Arenas...
At the risk of sounding ignorant and/or lazy at not looking up the answer elsewhere, What are the 'TX' and 'TN' references about in Chilean TAF's?
Thanks.

TX = forecast max temp for the time period
TN = forecast min temp for the time period

The Z time (indicated after the "/") is the approx hour at which these temps should occur.

These are found on other int'l TAFs as well
