Temperature Calendar Anomaly

A daily-updating map that reframes temperature anomalies as time rather than degrees. Instead of showing "5°F above normal," it shows how many days ahead or behind the normal temperature schedule each location is. If the forecast high for July 1 matches the climatological normal for July 15, that spot shows +14 days — two weeks ahead of schedule.
