NOAA 1991-2020 climate normals, blended from 3 nearby stations and adjusted for elevation; closest is Port Salerno (5 mi W), FL, 14 km away (close match). A normal year, not tonight's forecast: check the forecast low for the night itself. Why elevation is part of the blend: how county numbers are made.
