Philadelphia Weather Radar - Live Doppler Map (PA)

🌦️ Philadelphia Weather & Live Doppler Radar Guide

Situated along the Delaware River in southeastern Pennsylvania, Philadelphia experiences a humid subtropical to continental transition climate characterized by hot, humid summers and cold, precipitation-heavy winters. The Delaware Valley is subject to fast-moving Appalachian squall lines in the summer and powerful coastal Nor'easters in the winter. Having access to high-resolution, real-time Doppler radar is crucial for tracking sudden rain bands, urban flash flooding along the Schuylkill River, and freezing winter rain lines across Philadelphia, Bucks, Montgomery, and Delaware counties.

📡 NOAA NEXRAD Station: KDIX (Fort Dix, NJ / Philadelphia, PA)

Our interactive Philadelphia radar streams data from NOAA's Level-III NEXRAD radar station KDIX, located at Joint Base McGuire-Dix-Lakehurst in nearby Burlington County, New Jersey. Operating with S-band dual-polarization technology, station KDIX provides comprehensive Doppler coverage across the Greater Philadelphia metropolitan area, detecting both horizontal and vertical hydrometeors to distinguish between cold rain, sleet, wet snow, and severe hail cores.

🎨 How to Read Doppler Reflectivity (dBZ Scale)

Radar reflectivity measures precipitation density in decibels of Z (dBZ). Use this color reference when monitoring approaching storms on the Philadelphia radar:

⚠️ Seasonal Severe Storm Threats in Philadelphia

Winter in Philadelphia brings intense coastal Nor'easters that can dump heavy, wet snow or create treacherous freezing rain along the I-95 corridor. Summer brings severe multi-cell thunderstorms, damaging straight-line winds, and occasional localized tornadoes emerging from squall lines advancing from the Appalachian mountains.
