My grading system rates temps (cold is better) and snowfall, with pack and blockbusters (or lack of same) adding subjectivity. It uses the 4/3/2/1/0 for grades, with +/- adding or subtracting .33, just like when I was in college.
A: Best or near best at my location. I've given A++ (5 pt) for snow/cold that breaks records at the Farmington co-op. 3/01, 4/07 (SN), 3/14, 2/15 (temp).
B: Significantly better than average
C: At/near average
D: Significantly worse than average
F: Worst or near worst. I gave 12/15 an F- (-0.33 points) for temps as it obliterated Dec warmth records by huge margins.
hopefully a quick change to rain wherever you are headed
Thanks. However, my homeward drive gains both elevation and latitude, so p-type changes (if any) tend toward the opposite direction.
