Areas of fog, some potentially dense and reducing visibility to as low as one quarter mile, may be quickly encountered this morning while traveling. The fog may persist through daybreak. The reduced visibility could make driving conditions hazardous. If traveling, reduce speed, use low beam headlights, and allow plenty of distance ahead of you.

When a severe thunderstorm warning is issued, the storm may produce damaging winds, large hail, dangerous lightning, and heavy rain. In some cases, heavy rainfall produced by a severe storm can also lead to flash flooding. Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location.
