Have a crack at understanding it and predicting it for yourself....
I teach...
Analysis Chart (Synoptic) to give me what has just happened in terms of fronts, troughs, winds etc
Forecast Chart (Synoptic) to see what the met man predicts is likely to happen in terms of the same values. Obviously that depends upon you having a reasonable understanding of the types of weather associated with cold/warm/occuluded fronts, troughs, ridges, cols etc....
From there, I look at the 214's and 215's to give a general (but narrower) picture and look at the zones where the route passes through and the 'upwind' zones to see whats coming.
From there it's TAFs, but 24 or 36 hour TAFs are only available for the larger airports, and don't forget to check the airports en-route.
Hate met with a passion, probably because i struggled to understand why it was such a dark art and it's only through practice and reviewing what you thought was going to happen with what the MetMan said is going to happen against what actually did happen. Now, its a chore but not such a dreaded one.
Once you've mastered it, where you get it from doesn't really matter.
WeatherJack seems to be a good place with lots of imagery etc.
