Each forecast is scored out of 100 across four fields, by closeness to the actual recorded conditions. Those fields are high temp (30), low temp (30), wind (20, scored as a range when the source gives one) and precipitation (20, form and amount graded together, snow-aware). Same rubric for every town.
