Structural ice is a known flight hazard and there are plenty of forecasting products to help a pilot avoid it.

Because it is mainly an affliction of low-performance aircraft, it doesn’t receive as much attention.
This photograph was taken just after a cold front associated with a low pressure system passed over the field.
