National Weather Service forecasts indicate an advancing frontal system and developing coastal low will drive multiple rounds of showers and thunderstorms across the eastern U.S. on September 20, with the highest probabilities concentrated from the Appalachians through the Mid-Atlantic and Northeast. Official guidance highlights moderate to heavy rainfall potential in these areas due to enhanced moisture, instability, and onshore flow, while western and southern regions face more variable or lower chances tied to separate trough and ridging patterns. Model consensus from sources like the Weather Prediction Center shows evolving QPF details, with updates expected from new runs and NWS briefings that could refine timing, amounts, and exact boundaries ahead of market resolution.
