Icing conditions- What’s a real threat?

[poadeleted20]

Three ways to determine an icing threat, first is obvious..visible moisture and below freezing, this means there COULD be ice but does not mean that there WILL be ice. Second is PIREPS...check em before you go and see what other pilots have encountered around your area. Third is experience, if you experience ice you know where it is most likely to form and when it does form, just how fast it can and what the threat is.

Fourth and fifth are the Skew-T data and the more recent CIP/FIP products on the ADDS site.

Just got back from KMDW. It's raining though cold air on the ground. This is the SkewT. The ones since have gone to -2 or -3 at the surface., e.g, freezing drizzle.
