An air mass is a body of air with similar temperature and moisture characteristics throughout.
A front is the boundary between two different air masses.
High pressure systems tend to produce hazy conditions and few or no storms.
Low pressure systems tend to produce stormy weather.
The weather that occurs at the front is dependent on the temperature, moisture, and stability in the area.
Temperature and pressure differences can be significant on either side of a front.
Hazardous weather associated with fronts can include thunderstorms, icing, low ceilings/visibilities, and wind/turbulence.
Forecasts are educated guesses, not guarantees.
Compare the forecast to actual conditions and pay attention to trends.
ATC, flight service, and onboard datalink technology are excellent in-flight weather resources to help assess if and how conditions are changing. Use them strategically, not tactically.
