Take a look at this METAR:
KSGH 021156Z AUTO 28006KT 7SM UP CLR M03/M06 A3004 RMK AO2 FZRANO 50006 60000 T10271061 10000 21027 UPB26 P0000 SLP181
Any idea what the contraction “UP” stands for? That is “unknown precipitation”. You’ll see another mention of unknown precipitation near the end of the report, “UPB26” That means that the unkown precipitation began at 26 past the hour and in the case of the METAR quoted above, that would be 1126Z.
Something else about this METAR report which is unique: FZRANO. This stands for Freezing Rain (FZRA) information is not available. Most likely this is due to an issue with the observation station (although I’m surprised there isn’t a “$” at the end of the report. That symbol <$> would indicate maintenance is needed on the observation station).
Ok, just a couple of quick things I wanted to show you from my weather report this morning…back to my preflight!
