Heavier totals, with localized amounts exceeding 1-3 inches, occurred in south Alabama, northwest Florida, coastal Louisiana, and parts of Texas and Georgia, while lighter or isolated precipitation fell across the Ohio Valley and Northeast earlier in the day. Dry conditions prevailed in much of the northern Plains and Mid-Atlantic under continental air.
