Official station data show notable totals such as 0.66 inches in Raleigh and 0.25 inches in Baton Rouge, while Denver and Miami recorded only traces amid mostly dry conditions. Trader consensus aligns with these verified observations rather than pre-event model runs, as resolution depends on National Weather Service daily summaries and the measurable-rain threshold. Additional radar and station verification continues to clarify outcomes in active convective areas before final market settlement.
