Key Factors
- 01 Extreme Heat Warning in effect until 8 PM with heat index values around 100–110°F, creating danger if you are stuck in traffic or if a vehicle breaks down
- 02 Very high daytime temperatures near 97°F mean car interiors can become dangerously hot quickly, especially hazardous for children, pets, and people with health issues
- 03 Increasing chance of showers and thunderstorms after 2 PM, with some storms producing heavy rain that can reduce visibility and increase hydroplaning risk
- 04 Highest thunderstorm chances from roughly 4 PM through late evening (up to 70% in the nighttime period), including potential for heavy rain and ponding on roads
- 05 Air Quality Alert for code orange conditions, which may affect sensitive groups (asthma, heart/lung disease) during outdoor exposure or if driving with windows open

Recommendation
Try to do necessary driving in the cooler, storm-free part of the morning, roughly 8:00–11:00 AM, when it is sunny, hot but not yet at peak heat, and with minimal storm risk. For evening travel, a relatively better window is around 9:00–11:00 PM, when temperatures have cooled and the probability of storms dips somewhat, but be prepared for possible showers or thunderstorms and postpone nonessential trips if active storms are nearby.
