Turns the state of the atmosphere into a forecast somebody has to act on.

Aviation forecasting is applied physics with a deadline. The output is not a description of the weather, it is a decision aid: will this airport go below minimums, will the icing be in the climb, is that line of storms going to sit across the departure route at the wrong hour. Being usefully specific and being honest about uncertainty are both part of the job.
The standard route, with maths and physics behind it.

Covers research, broadcast and forecasting meteorologists together. Aviation forecasting is a small part of an already small occupation, about ten thousand seven hundred people in the whole country.
You will be wrong in public, on a schedule, and the verification is kept. Shift work covers the clock because weather does. And the pressure to say something definite when the honest answer is a probability is constant, and giving in to it is the one professional failure that matters.
