Key Factors
- 01 Hourly data shows 0-1% precipitation chance from 7am through about 8pm, with sunny to partly sunny skies
- 02 Temperatures of 59-79F rule out ice risk; winds are light at 2-9 mph with no gust hazard
- 03 Rain chances start rising around 9-10pm (12-28%), with showers and thunderstorms likely from about 1am and heavy rain possible
- 04 Flood Watch is in effect until the morning of Sept 13 for excessive runoff and possible flooding of low-lying and flood-prone roads
- 05 Patchy fog is forecast between 2am and 5am, and no visibility data is provided, so the extent is uncertain
- 06 The Flood Watch text says 'late tonight', and the alert end time differs between fields (00:00 vs 12:00PM Sept 13), which adds slight uncertainty

Recommendation
Drive in the morning between 8:00am and 11:00am, or in the evening between 4:00pm and 8:00pm, when it is dry and calm. Avoid driving after about 10pm and especially from midnight through the morning of Sept 13, when storms, heavy rain, fog, and flooded roads are possible. Never drive through flooded roadways.
