    KFAR 111753Z 28029G38KT 10SM OVC033 16/05 A2980 RMK AO2 PK WND 28038/1749 SLP091 T01560050 10189 20139 53036

    I am trying to "decipher" the METAR past the PK mark. I understand that wind was 38 knots @ 280 at 1749 Z. What is after that?

    Sea level pressure, then full temp. Not sure last few sets of numbers

    SLP=Sea Level Pressure
    T01560050 is a more accurate Temp and Dew point 16/05= 15.6/5.0

    Annnd...
    T00640036 10066 21012 58033 TSNO $

    T00640036=HOURLY TEMPERATURE AND DEW POINT
    reported to nearest tenth of oC; sn: 1 if temperature or dew point below 0oC and 0 if temperature/dew point 0oC or higher.

    10066= 6-HOUR MAXIMUM TEMPERATURE,maximum temperature for past 6 hours reported to nearest tenth of degree Celsius

    21012= 6-HOUR MINIMUM TEMPERATURE, minimum temperature for past 6 hours reported to nearest tenth of degree Celsius

    58033=PRESSURE TENDENCY, the character (a) and amount of change in pressure (ppp) in tenths of hPa for the past 3 hours.

    $= Maintenance is needed on the system

    I'm bored at work.

    SLP091 means the Sea Level Pressure is 1009.1mb. T01560050 means Temperature is 15.6 and the dewpoint is 5.0. Its just a more accurate reading. From then on, I can't help you.

    Cool! Am bored at work too. The wind is howling outside, so I jumped on the interwebs to see what the METAR said.

    Thanks for the link and response!

    Temperature/dewpoint does not matter for us pilots but for forecast models the 10th of a degree can make a big difference. SLP used for surface analysis.

    Read my entire post- when was the last time you read a performance chart that had 10ths of degrees? Though in fairness to you I may not have been clear.

    He probably thought you meant T/D in general, and not the specific reading at the end of the METAR.

    It was the forecast models part that threw the sentence off. It reads like: pilots dont care about the t/d spread but forecasters are immensely concerned with tenths of degrees. No worries. Why I asked, wasn't meant to sound snippy.
