Recommendation
Prefer driving in the morning from 7 AM to noon, when conditions are mostly sunny and precipitation chances are low. Avoid or postpone nonessential driving from about 4 PM through 8 PM because thunderstorms are most likely; if driving then, slow down and watch for rapidly changing conditions. A later evening slot around 9 PM to 10 PM may be somewhat better than 5–8 PM, but thunderstorms remain possible, so check conditions before departing.
