As a degreed meteorologist myself, with a masters in applied meteorology, and many years forecasting experience, I can say these men and women are the spear head of an efficient operation! Any airline would drool at the resource this department provides for their front-line crews.
With that said, and most meteorologists agree, that forecasting is theoretical and an art, and we forecast using all data available - including pilot reports. Please provide these reports to your company even if you think they are inconsequential - but especially if the weather is different than planned! A few keystokes on ACARS will provide the gaps in data your forecasters need.
