Summary
Scattered to numerous showers and thunderstorms, some with very heavy rain under a Flood Watch from midday into tonight, will make driving wet and locally hazardous, especially in poor-drainage and urban areas. Conditions are generally driveable for most people but extra caution is needed during heavier storms and in areas prone to flooding.

Key Factors
- 01 Flood Watch in effect from noon through late tonight for possible flash flooding from excessive rainfall, especially in urban and poor-drainage areas.
- 02 High thunderstorm and shower chances for much of the day, with probabilities often 60–90% from late morning through early evening, increasing the chance of brief torrential downpours and water-covered roads.
- 03 Forecast rainfall totals of 1–2 inches with localized 3–5 inches in strongest storms and possible rainfall rates of 1–3 inches per hour, which can quickly overwhelm drainage and create hazardous hydroplaning and flooding conditions.
- 04 Temperatures well above freezing (upper 60s to low 80s °F), so no ice risk, but wet roads and ponding water remain concerns.
- 05 Winds remain light (generally 2–9 mph), so wind is not a primary driving hazard today.
- 06 Rain and storm chances continue into the evening and overnight with mostly cloudy skies and high humidity, which may reduce visibility at times, especially in heavier showers or patchy fog late night.

Recommendation
If you can choose timing, a relatively safer morning window is around 7:00–9:00 AM, before thunderstorms become more widespread and intense. A relatively safer evening window is around 8:00–10:00 PM, when rain and storm chances and intensities are generally lower than during the afternoon peak, but still drive carefully and avoid any roads with standing or moving water.
