Weather Maps

About the weather maps for Piedmont

Each preview is centered on Piedmont, with the red pin marking its approximate location. Satellite imagery provides cloud context, radar shows nearby precipitation, and the fog view shows the marine-layer or low-cloud field when that regional layer is available.

These images cover a wider area than the point forecast, so a nearby cloud or rain band may not be directly over Piedmont. Open a preview for the interactive map and its latest timestamp before making a weather-sensitive decision.

What the Piedmont climate comparisons mean

These cards compare recent conditions at Piedmont with the available local baseline. Temperature and year-to-date rainfall use long-term normals when available; fog, sunshine, wind, and comfort use the matching recent or modeled baseline identified on each card.

Positive and negative differences describe how Piedmont departs from its own usual pattern. They should not be read as a direct comparison with another city or as a forecast beyond the period shown.

Historical Climate Data

Long-term weather patterns and climate data

Data sources: NOAA URMA for recent temperature history, NOAA Stage IV for recent precipitation, NOAA HRRR for fog, cloud, wind, humidity, and sunshine signals, and NOAA 1991-2020 climate normals for long-term baselines.
