Paste a METAR or pick a sample. The sky it describes is built around the airport: cloud layers at their real heights, visibility, wind, rain and storms. Tap any group of the report to see it in the scene, then get a go or no-go for your flight.
A METAR is always in the same order. Learn the order and every report gets easier.
Station · day and time (Zulu) · wind · visibility · weather · sky · temperature/dew point · altimeter · remarks.
Tap each decoded group and watch what lights up.
Direction the wind blows from, in degrees true, then speed in knots. 22015G24KT is from 220° at 15 knots, gusting 24. VRB means variable; 00000KT is calm.
Load the KFTY sample and look at the windsock.
Visibility is in statute miles. - is light, + heavy, VC in the vicinity. BR mist, FG fog, HZ haze, RA rain, TS thunderstorm.
Load KPDK fog, then switch to Pilot view.
Heights are hundreds of feet AGL: BKN035 is broken at 3,500 ft. The ceiling is the lowest BKN, OVC or VV layer. CB after a layer means cumulonimbus.
Load KRYY: SCT008 is not a ceiling, BKN012 is.
27/23 is 27 °C with a 23 °C dew point. M means minus. A2987 is an altimeter setting of 29.87 inHg. Hot air and low pressure raise density altitude.
Load KMGE and check the density altitude readout.
3 SM visibility, 500 ft below clouds and 2,000 ft horizontally from them. Wind and storms are about your aircraft's limits and common sense.
Raise your planned altitude under KRYY's low layer.
