Key Factors

- 02 Peak heat is 12pm-7pm (98-102F)
- 03 Isolated thunderstorms are possible 4pm-11pm (15-24% chance), becoming scattered around 11pm (26-30%) and lasting until about 2am; storms could bring brief heavy rain, reduced visibility, and gusty winds
- 04 Winds are light (3-10 mph), so crosswind risk is low outside of storms
- 05 Code Orange Air Quality Alert applies to sensitive groups
- 06 Visibility data is not provided, and storm timing is uncertain

Recommendation
Morning: drive between 7am and 10am, when it is sunny, dry, calm, and still in the 83-90F range. Evening: drive between 8pm and 10pm, when temperatures fall to about 89-92F and storm chances are still only isolated (about 20%); check radar before leaving. Avoid midday and afternoon driving (12pm-7pm) if possible. Make sure the AC and cooling system work, carry water, and never leave children or pets in the vehicle. If a thunderstorm develops, slow down, use headlights, and pull over safely if visibility drops.
