It is a raw report code from weather stations. AI describes it:

 

KCDC: This is the ICAO airport identifier. KCDC stands for Cedar City Regional Airport, located in Utah, USA.

180722Z: This indicates the date and time of the report. It was issued on the 18th of the month at 07:22 UTC (Z is Zulu time, which is UTC).

AUTO: This indicates that the report was generated automatically by the weather station, without human intervention.

36007KT: This reports wind conditions. The wind is coming from 360 degrees (true North) at a speed of 7 knots.

5SM: This indicates visibility. The visibility is 5 statute miles.

-TSSN: This indicates that light snow (denoted by the minus sign) is occurring along with the presence of snow (TSSN) in the vicinity.

The AI has got the majority of it right but I can spot one clear mistake: TS means "thunderstorm" and SN means "snow", and a - sign means "light", so -TSSN means "light snow with thunderstorm".
