Key Factors
- 01 Flood Watch is in effect from 2 PM EDT today through Monday evening; heavy rain may exceed 2 inches in an hour and cause flash flooding, especially in urban, low-lying, and poor-drainage areas.
- 02 Thunderstorm chances begin around 1 PM, rise through the afternoon, and are likely from 5 PM to 10 PM; showers and thunderstorms are forecast through midnight.
- 03 Heavy rain is specifically possible with storms; rainfall of 1 to 2 inches is forecast tonight, reducing visibility and increasing the risk of water-covered roads.
- 04 Precipitation probability rises from 33% at 2 PM to 61% at 5 PM, 72–74% from 6–8 PM, and peaks at 89% at 10 PM.
- 05 A Heat Advisory is in effect 8 AM–8 PM, with heat-index values of 95–100; this is mainly a health concern but can affect drivers if stranded or handling a breakdown.

Recommendation
Morning: If travel is necessary, the safer window is 7 AM–noon EDT, before storm chances increase; carry water and avoid prolonged outdoor exposure. Evening: No reliably safe evening driving window is forecast—avoid travel from 5 PM through midnight EDT. If driving cannot be postponed, check for active Flash Flood Warnings, do not drive through flooded roads, and stop in a safe location if heavy rain or lightning sharply reduces visibility.
