Another "soft" rule I have is to not fly long distances when the
weather turns out different from yesterday's forecast. If it was
supposed to be lousy weather and turns out to be CAVU, I stay close
to home. The weather people obviously don't have clue today.

If the forecast is a bust, it's good to think about *why* it was wrong.

Weather changes for two basic reasons -- either the qualities of the
airmass where your at has changed, or a different airmass has moved in.
Let's say yesterday they were forecasting today to be rainshowers,
thunderstorms, and strong gusty winds, but it turns out it's really
CAVU. It could just be that an approaching cold front got here faster
than expected and the frontal mess is already past. One quick look at
the weather map might show you that there's a high over the midwest and
perfect weather clear out to colorado. Surely that's no reason to
cancel a trip?
