Key Factors
- 01 Flood Watch in effect from noon EDT through late tonight for flash flooding from heavy rain
- 02 Showers and thunderstorms likely much of the day with 80-85% precipitation chance in the afternoon
- 03 Rainfall rates up to 1-3 inches per hour possible in stronger storms, risking hydroplaning and ponding on roads
- 04 Localized rainfall totals of 3-5 inches possible, with flooding in poor drainage and urban areas
- 05 Patchy fog developing overnight between 1am and 5am reducing visibility
- 06 Winds are light (under 10 mph), so wind is not a major factor

Recommendation
Safest morning window is 7-8 AM before storms develop; in the evening, conditions improve after about 9 PM as precipitation chances drop, so 9-11 PM is the better window. Avoid driving from about noon through 7 PM when heavy thunderstorms and flash flooding are most likely, and use caution overnight due to patchy fog.
