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.

Ray's Weather publishes a per-town high, low and sky icon, so his town boards are graded on those. The icon is read as his precipitation call (a dry icon scores as a no-rain forecast, a rain or storm icon as rain). His wind text is one identical regional string across every town, so wind stays an honest forfeit here rather than a stamped guess. See the methodology for the icon mapping.
