Key Factors
- 01 Thunderstorms are likely from 8:00 AM to 11:00 AM, increasing the risk of heavy rain, reduced visibility, and hazardous road conditions.
- 02 Rain is likely or ongoing for much of the day, with very high precipitation chances peaking around 1:00 PM to 4:00 PM (83% to 95%).
- 03 Daily forecast indicates a 100% chance of precipitation during the day with 0.25 to 0.50 inch of rainfall possible.
- 04 Roads may remain wet and visibility may be reduced for extended periods, especially during heavier showers.
- 05 Winds are relatively modest at 6 to 12 mph daytime and 8 to 13 mph at night, so wind is not the main hazard.
- 06 No active weather alerts are posted, which lowers risk somewhat, but does not remove the hazard from persistent rain and thunderstorms.
- 07 Visibility data is not provided, so confidence is reduced somewhat regarding the severity of driving impacts.

Recommendation
Avoid nonessential driving from 8:00 AM to 6:00 PM, especially 8:00 AM to 11:00 AM during likely thunderstorms and 1:00 PM to 4:00 PM during the highest rain chances. If you must drive, the safer morning slot is 7:00 AM to 8:00 AM before thunderstorms become likely, and the safer evening slot is 8:00 PM to 10:00 PM when rain chances drop to 31% to 20%.
