Strong/Severe Thunderstorms - Scattered showers and thunderstorms are expected to develop this afternoon. A few strong to severe storms are possible this afternoon into the early evening hours. The primary threat will be isolated damaging winds up to 60 mph, but cloud-to-ground lightning and brief heavy rainfall can also be expected. If thunderstorms persist over any one location, then localized flash flooding will also become a concern. If you have outdoor plans this afternoon and evening, please monitor the latest weather conditions and have a plan for shelter if threatening weather approaches your location.
