Summary

Driving today includes an Extreme Heat Warning with heat index up to ~109 and a window of isolated to scattered thunderstorms from late afternoon into the night.

Key Factors

01 Active Extreme Heat Warning (dangerously hot; heat index 100–110; hottest through today).
02 Very high temperatures peaking around 101–103F (hourly up to 102F) increase risk of heat illness if stranded and can stress vehicles/tires.
03 Thunderstorm chances increase after ~4 PM: hourly shows isolated showers/thunderstorms 16:00–23:00 with PoP ~15–26% (daily: isolated after 4 PM; scattered before 2 AM).
04 Rainfall amounts could reach ~0.10–0.25 in (overnight period), which can create slick roads/visibility reductions during any storm (exact intensity/visibility not provided).
05 Visibility data is not provided, so storm-related visibility impacts can’t be quantified (adds uncertainty).

Recommendation

Morning safer window: 07:00–11:00 (sunny, very low precip chances). Evening safer window: 21:00–23:00 only if storms are not occurring on your route; otherwise delay travel until after the thunderstorm window ends (scattered storms possible until ~02:00). Avoid/limit driving 14:00–20:00 due to peak heat and the onset of thunderstorms after ~16:00; if you must drive, ensure A/C works, carry water, and never leave people/pets in the car.
