Key Factors
- 01 Heat Advisory in effect until 8PM with heat index near 95F, mainly a concern for vehicle/tire stress and roadside emergencies, not direct driving hazard
- 02 Increasing chance of showers and thunderstorms starting around 1PM, rising to 60-65% likely from 4PM through the evening into the night
- 03 Thunderstorms can bring sudden downpours, reduced visibility, and lightning risk, especially between 4PM-11PM
- 04 Wind gusts up to 23 mph possible during storms, which could affect high-profile vehicles
- 05 No fog, ice, or winter weather concerns; temperatures well above freezing all day

Recommendation
Best driving windows are early morning from 7AM-12PM when skies are sunny and precipitation chance is low (under 10%), and late night after 11PM when storm activity tapers off (rain chance drops to ~39%). Avoid driving between 1PM-11PM if possible due to increasing thunderstorm activity and heaviest rain risk between 4PM-8PM; if travel is necessary during this window, watch for sudden downpours and lightning.
