Despite tying Brad Sussman for the single-day worst error (21 degrees off the actual high) early in the experiment, Bruce Kalinowski ends up with very respectable numbers. Bruce doesn't take any gambles with his predictions, preferring warming and cooling trends which one can see reflected in the smooth curves in the chart above.

Advice: Although he can't tell you the exact temperatures in advance (nobody can), Bruce knows when it's going to get warmer or colder. Take note of the direction his forecast highs point and wear layers.
