Summary
Today is warm and mostly dry in the morning, but rain showers and thunderstorms become increasingly likely from late morning into the afternoon and continue into the evening. Wet roads and lightning/visibility changes during storms make driving riskier, especially during the main storm-probability window.

Key Factors
- 01 Increasing precipitation risk: probability rises from ~15% at 11am–12pm to ~44–51% from 4pm–8pm and stays ~47–51% overnight.
- 02 Thunderstorms are explicitly forecast (“Chance Showers And Thunderstorms”) from about 12pm through at least 11:59pm, increasing risks of lightning, sudden heavy rain, and rapidly changing road conditions.
- 03 Wind is generally light-to-moderate (about 2–9 mph) and does not look extreme, so the main hazard is precipitation intensity and storm impacts.
- 04 Morning is the driest period: from 7am–10am precipitation chances remain low (0–8%) and skies are mostly sunny/partly sunny, which is safer than later in the day.

Recommendation
Safer to drive in the morning window of 7:00–10:00 AM (low rain chances ~0–8%). For the evening, avoid 4:00–8:00 PM when thunderstorm probability is highest (~44–51%); if you must travel later, consider after 9:00 PM when conditions remain storm-possible (~50%) but temperatures are lower and winds are lighter (5:00–3:00 mph range).
