Key Factors
- 01 Rain showers likely: PoP peaks around 10am–12pm (68–72%) and remains elevated through early afternoon (up to 63% around 11am).
- 02 Wet road conditions are likely, increasing stopping distance and hydroplaning risk, especially during heavier shower periods (rain showers likely before 5pm).
- 03 Temperatures are in the upper 50s to low 60s (57–62°F), which reduces (but does not eliminate) risk of ice; the main hazard is wet/slippery pavement.
- 04 Light to moderate northeast/east winds (about 5–8 mph) are unlikely to cause major crosswind issues for most vehicles.

Recommendation
Safer driving windows are when precipitation chances are lower: drive in the morning around 7:00–8:00 AM, when the forecast is “chance rain showers” (46–44%). For the evening, conditions look best from about 6:00–7:00 PM, when precipitation chances are very low (around 5% and “cloudy/mostly cloudy”). If traveling during 9:00 AM–1:00 PM (especially 9–12), slow down, use headlights, and increase following distance due to likely wet roads.
