11106 The 6 hour maximum temperature (the highest air
temperature recorded during the previous six
hours) is -10.6 C. The first 1 is the group
identifier, the second is the sign (0 for + or
1 for -), and the final three digits are the
temperature (106 is 10.6).
21131 The 6 hour minimum temperature (-13.1 C) coded
as above. Here, the 2 is the group identifier.
4/001 The total snow depth on the ground in inches.
Usually found in the 06 and 18Z observations.
411061131 A nine digit group beginning with a 4 as the
group identifier would contain the 24 hour
maximum and minimum temperatures, in that order,
coded as in the "T" group above. Usually found
in the 08Z observation.
51016 The "5" group is the 3 hour pressure tendency
and amount of change. The the second digit is
the tendency (coded, where 0-3 are going up, 4
is steady, and 5-8 are going down) and the last
three digits are the change (016 is 1.6 mb).
60000 3 and 6 hour precipitation amounts encoded as
above. 60217 would indicate 2.17 inches. The
3 hourly precip is reported in the
70025 The 24 hour total precipitation (this will be
liquid equivalent for frozen precip) in 1/100s
of an inch. 70025 would be 0.25 inch. This
is usually found in the 12Z observation.
98096 Duration of sunshine in minutes. 98096 means
there were 96 minutes of sunshine during the
day. Usually in the 08Z observation.

Nice, I have referenced that exact page in the past.

I was told the same thing! AKA - my instructor didn't know them himself!
I've got to figure out an acronym to help remember them. Anyone?....

I expect my students to know that the "5" numbers are the pressure tendency, as well as every other numeric sequence in the remarks, because unless they know this, how can they know that the numbers contain no information for them? But I don't expect them to be able to decode what the tendency is; that information isn't intended for pilots, but for meteorologists.

I just tell them to look it up.
I mean, I have a general understanding but, they are not life threatening, just fun to know stuff.
