I am intrigued by the ding against the operator for not "... correctly completing the flight risk analysis forms."
The benefits of using them is obvious, but it lurches dangerously close to assuming that everything you encounter while in the air can be planned or anticipated. Surely the most effective flight safety device for being able handle the unexpected is called Captaincy?
That said, in this particular case you didn't need a flight risk analysis form, you only needed a TAF and METAR.
