Recommendation
Morning slot: If you must drive, the safest window is before 8:00 AM EDT when precipitation probability is only 15-49% (though smoke and reduced visibility remain concerns). Evening slot: No safe evening window exists today — thunderstorms with 84-90% probability persist through the entire evening and night. If possible, avoid driving entirely today. If you must travel, go before 8:00 AM and avoid low-lying roads and flood-prone areas.
