Key Factors
- 01 Chance of precipitation rises from ~7% at 3-4pm to 25% by 5-6pm and 41% by 6-7pm.
- 02 Rain Showers Likely from about 7-8pm through 9-10pm (hourly probability ~61–66%).
- 03 Wind speeds increase to ~15–16 mph in the late afternoon/early evening, with gusts noted up to 28 mph (daily forecast) and gusts up to 26 mph overnight (daily forecast).
- 04 Temperatures remain above freezing (around 45–63°F), so the main risks are wet roads/limited visibility from rain and wind gusts, not ice.

Recommendation
Safer to drive during a lower-risk window in the morning: 7:00–11:00 AM. If you must drive later, choose the earlier evening before the wettest period starts: 5:00–6:00 PM (conditions deteriorate after that, with likely rain later in the evening).
