Lingering moisture from a recent nor'easter continues to drive scattered showers and drizzle across the Northeast US on September 28, 2026, with National Weather Service models showing 40-70% precipitation probabilities and light accumulations under northerly flow. In the Southwest and Four Corners region, scattered convective showers are possible amid partly cloudy conditions and moderate temperatures, while the Weather Prediction Center maintains a marginal excessive rainfall risk. Broader patterns include isolated showers in the Pacific Northwest and tropical moisture supporting rainfall in parts of Brazil and convective activity over northwest Spain. Updated WPC quantitative precipitation forecasts and next NWS model runs will refine these short-term outlooks ahead of any market resolution thresholds.
