Drought in the 2010s: 24 records against 6 in the decade before, 24 of them forecast-zone records. Cells marked z rose mostly through zone records. The local National Weather Service office files these once per forecast zone, so a change in how it draws its zones or splits a storm into records moves this count as much as the weather does; read it beside the Graham County days with a record above.
