Key Factors
- 01 High probability of precipitation and rain dominating the day: ~65% by 11:00-12:00, rising to ~82–94% from mid-afternoon through evening and night.
- 02 Rain continues after dark (about 18:00 onward), with temperatures near 51°F, which can increase slick-road risk from wet surfaces.
- 03 Gusty winds: hourly winds commonly 10–12 mph, and the daily forecast notes gusts up to ~23–24 mph, which can worsen control and visibility (especially for higher-profile vehicles).
- 04 Reduced temperatures falling from around 58°F early to around 50–52°F later increases the chance of more slippery conditions late day (no freezing/ice type reported, but wet-road slickness remains a concern).

Recommendation
Avoid driving during the wettest, windiest period. Safer window (morning): 07:00–09:00 when rain chances are lower (18–28%) and conditions are milder. Safer window (evening): 18:00–19:00 is only marginally better than later hours (rain likely throughout evening), but attempt travel before ~20:00 if you must drive; after 20:00 the probability stays very high (~87–94%) with continued rain.
