UV across the country today
The strongest sun among the cities we track today is over El Paso, TX, where the index peaks near 5. None of them reach the very-high band today. The index tracks the sun's angle, not the heat: it peaks within an hour of solar noon, runs higher at altitude and roughly doubles off snow or water.
