An XKCD comic about how to decode a METAR:
METAR - "Meter" (Usually misspelled)
KNYC - Station ID
251600Z - Time (25:16:002)
18035G45KT - Wind speed has been 18,035 knots for a good 45 minutes now.
6SM - Observer is a size 6 small.
VCFCFZVA - Sorry, the station cat walked on the keyboard.
+BLUP - Weird noise the sky made earlier.
NOSIG - The observer has no significant other :(
LTG OHD - We overheard someone saying there was lightning.
A3808 - Hey look, an Airbus A380-800!
RMK - Remarkable!
A02 - Fanfic archive equipped with a precipitation sensor.
SLP130= - Observer got sleepy around 1:30.
Image alt-text on the website: "In the aviation world, they don't use AM/PM times. Instead, all times are assumed to be AM unless they're labeled NOTAM."
