On October 1, 2026, observed rainfall patterns reflected interactions between cold fronts, tropical moisture, and regional high-pressure systems, with official National Weather Service data showing marked regional variation across the United States. Heavy precipitation occurred in parts of the southern Plains and Gulf Coast, including 3.47 inches in Dallas-Fort Worth and 1.79 inches in Fort Lauderdale amid thunderstorms, while many Northeast and Mid-Atlantic stations recorded trace or zero amounts under mostly dry conditions. Internationally, China’s Central Meteorological Administration reported localized downpours exceeding 50 mm in Chongqing, Guizhou, and adjacent provinces, while Hurricane Rachel and an advancing cold front drove widespread heavy rain across much of Mexico. These verified measurements from surface networks and satellite-derived estimates provide the resolution baseline for market outcomes, with no further model updates expected.
