US TAF/METAR Question
Evening,
Could someone please shed any light on the obvious differences between European way and the US way on the PBI TAF/Metar below:
ie, what does P6SM mean and "RMK AO2 SLP145 T03060233 53007="
Cheers

This might be a useful resource for a US TAF etc.:
http://aviationweather.gov/static/help/taf-decode.shtml
Specifically, P6SM means forecast visibility of Plus 6 Statute Miles.
And for METARs:
http://www.srh.noaa.gov/lzk/html/metar.htm
And FMH-1 is the definitive statement on US METAR coding.
So for your specific example: RMK AO2 SLP145 T03060233 53007=
is Remarks: automated station with a precipitation discriminator : Sea Level Pressure 1014.5mb : Temp 30.6, dewpoint 23.3 : 3 hourly pressure change "Decreasing or steady, then increasing; or increasing then increasing more rapidly" 0.7 hectopascals change in 3 hours

Remarks...in this case "AO2 SLP205"
Note: The remarks section of an observation may have a variety of data. The most common remarks include "AO2" indicating an ASOS observation and SLP indicating sea level pressure in millibars (example: "SLP205"means a sea level pressure of 1020.5 millibars).
