blueloo,
The AO2 means its an automated site with a automated rain guage, P0005 is the amount of rain in hundredths of an inch since last hour (its a US site measurements are in inches). LTG DSNT ALQS, just means distant lightning over 10 miles away miles in all quadrants, sometimes will see LTG DSNT N which means lightning 25 statute miles north of the station. DSNT means over 10 miles away. VC means within 10 miles Other unusual ones .. OCNL LTGICCG OHD occasional lightning, in cloud, and cloud ground overhead DS - Duststorm SS - Sandstorm MIFG - Shallow fog DRDU - drifting widespread dust DRSA - drifting sand DRSN - drifting snow VCSH W would mean precipitation of unknown intensity within 10 statute miles west of the station PRESFR - pressure falling rapidly TN18/16Z minimum temperature 18 degrees occurred around 1600 UTC TX35/00Z maximum temperature 35 degrees occurred around 0000 UTC :ok: |

The NDV. Is that an OZ thing? As we couldn't find it in the Jepps the other day and had no idea till we asked the tower at OOL. Even they had a few seconds think on it too.

------- OCNL LTGICCG OHD occasional lightning, in cloud, and cloud ground overhead ------ I believe OCNL should be read as "Well Seperated" |
OZAZTEC,
What I had posted was correct for lightning. Lightning codes in metars ....
:ok: |
NCD - No Cloud Detected |
The abbreviations were developed during the times when teleprinters were being used to send these messages and the charge was per character, making full text messages expensive.
There is no need for abbreviations these days, why do they still persist in using them. |

And the public servants wouldn't know more trivia than the users.
