Recommendation
Drive normally today. Best morning window is 9:00-11:00am once humidity drops and sun is up; best evening window is 5:00-8:00pm before rain chances increase late. Use extra caution around 7:00-8:00am for possible patchy mist and after 10:00pm as showers become more likely toward midnight.
