Recommendation
Avoid unnecessary travel today if possible. Safer driving windows are limited: morning 7:00-8:00am before storms become more widespread, and evening 8:00-9:00pm only if you must travel, though rain and thunderstorms are still likely. Do not drive through water-covered roads, and be prepared for rapid changes in conditions.
