What are variable wind direction at 3 knots, greater than 6 statue miles, few clouds at 3000 feet?
What is 700' AGL?
Gray or white, patchy clouds that usually extend over a wide area, produce light turbulence, and may contain supercooled water droplets
What are Altocumulus clouds?
An observation of surface weather that is reported in a standard format.
What is a METAR
A solid magenta line on a map indicates this airspace
What is Class C?
Looks like large mounds of cotton with billowing cauliflower tops and contain moderate to heavy turbulence with icing and often develop into thunderstorms.

What are supercooled water droplets?
Issued every 6 hours with amendments issued, as necessary, for weather phenomena that are of operational interest to all aircraft.
What are AIRMETs (WAs)?
Class B airspace typically extends to this altitude.
