The elevation of the indicated forecast area on the map shown on the
page I referred to, and as pointing to my Middle Tennessee location,
shows elevations in feet.
As luck would have it, I am not situated squarely within a forecast grid
cell but am near a corner of four such cells.
I am not familiar with Wireshark or with the website from which you
downloaded this data, Pierre. I took a quick look just now at their
Users Guide and their man page and had no success seeking 'weather' for
the command description.
I noticed that this data seems to come from the METARs and is "decoded"
by KRDU (your local NWS Forecast Office). METARs provide present/last
observations and do not provide forecasts. KRAH must be providing the
forecast info. I think you might like like to contact them about
formatting issues.

I ran Wireshark while running "weather -f" ("-f" means forecast; without the
option it displays current weather) and captured the following conversation:

The text starting with "City Forecast" was output verbatim, except for the
blank line. The current conditions, which include both °C and °F (but without
the degree sign, even though the charset is UTF-8), are from
http://weather.noaa.gov/pub/data/observations/metar/decoded/KRDU.TXT .
I went to the site you mentioned and found the elevation given as 200 ft. It
is 200 m, which I pointed out to the webmaster.
