1. Each geographic region has key local forecast situations.
       We showed 8 examples for the lower Sacramento valley.
2. There are other significant weather situations that occur elsewhere.
       We discussed 7 examples in general terms.
3. Forecasts involve:
   • An educated and organized look at the guidance. (Selecting which guidance to examine.)
   • Then an interpretation of that guidance by combining two collections of knowledge, one "theoretical" and the other "empirical"
     1. What types of quantities, structures, etc. are important to look for? For example, we mentioned
        • locations of trough axes; maxima in vorticity, etc.
        • whether there is PVA or NVA; WAA or CAA
        • shape of the trough (implying direction of motion)
        • soundings for potential instability, etc.
     2. What does a particular pattern mean when you see it? This was the intent behind showing example patterns. For example:
        • recognizing characteristic patterns for significant weather conditions.
        • sleuthing out why the model produces precip where it does: is it frontal? is it from an upper level disturbance? convective? lake-effect? orographic lifting? low-level convergence zone? (a combination of the these?)
        • deducing features not plotted by model output (especially locating where the fronts are in the forecast output)
